Whether you need power for your home during an outage, portable power for yard work or a party, or electricity you can take on the go for a camping or RV trip, there’s a generator for you. The best generator is a convenient source of power in any situation. But choosing the right generator is about more than just power and performance – it’s also about choosing a generator that fits your specific needs.

To help you find the right generator, we looked at a number of different types of generators and the features that differentiate them. We first considered the type of generator – whether it is a conventional gasoline-powered generator, a dual-fuel generator that can run on propane and gasoline, a quiet and efficient inverter generator, or even a solar generator. We also looked at both portable generators, which are easy to take anywhere you need power, and standby generators, which are specifically designed for powering your home during an extended outage. We considered the rated and maximum power output of each generator, which determines what and how many appliances and tools you can power. For example, a 2,000-watt generator would be perfect for camping and tailgating purposes. If you need a compact and portable generator to keep all your essential appliances and tools running, a 4000-watt generator would be enough. A 10,000-watt generator, at the same time, will offer plenty of power during an outage. Finally, we considered features like the amount of time you can run your generator continuously and the price and warranty of each generator.

Yamaha EF2000iSv2Best Portable Generator

  • Type: inverter
  • Fuel: gasoline
  • Rated/surge watts: 1,600/2,000
  • Engine: 79cc, OHV, air-cooled, single cylinder, 4-stroke
  • Fuel tank capacity: 1.1 gal.
  • Runtime: 10.5 hrs (1/4 load)
  • Outlets: (2) 120V AC, (1) 8A 12V DC
  • Starting system: recoil
  • Noise level: 51–61 dBA
  • Warranty: 3-year limited

This impressive 2,000-watt inverter generator from Yamaha won our Editor’s Choice award and our pick as the overall best portable generator thanks to its impressively long runtime and compact design. The generator doesn’t produce a huge amount of power – just 1,600 watts of continuous power – but instead focuses on providing enough power for a set of outdoor tools or basic amenities during a camping trip.

Where the generator really shines is in its ability to run for up to 10.5 hours at a 50% load – on just over a single gallon of gasoline! That’s one of the longest runtimes of any inverter generator in this size class and the efficiency of the four-stroke Yamaha engine is sure to save you money on fuel over the long-term.

Another advantage of this generator, especially for use on camping trips, is that it is extremely quiet. The generator produces just 51.5 dB of noise at 25% power and even at full output users report that you can hold a conversation around the machine. The EF2000iSv2 is also tiny and lightweight – it is less than 2.2 cubic feet in size and weighs less than 45 pounds – so carrying it from your car to your campsite or storing it in the trunk of your car is never a problem.

To top it all off, the generator is built with a Yamaha engine. That contributes to the somewhat high price of this model compared to its competitors, but you can be sure that the generator will last for decades of use without any issues. To add to that piece of mind, Yamaha offers a three-year warranty.

The only real downside to this generator is that it lacks a few features for convenience – most notably an electric starter and a USB charging port. However, these are hardly an issue for the vast majority of users.

  • Inverter generator
  • 10.5-hour runtime at 50% load
  • Extremely quiet at just 51.5 dB
  • Lightweight and very compact
  • Highly reliable and durable Yamaha engine
  • Three-year warranty
  • Expensive compared to competitors
  • Lacks electric starter and USB charging port

Champion 3400-Watt Dual Fuel Inverter, 100263Best Dual-Fuel Inverter Generator

  • Fuel: gasoline, propane
  • Rated/surge watts: 3,100/3,400 (gas), 2,790/3,060 (LPG)
  • Engine: 192cc Champion 4-stroke OHV
  • Fuel tank capacity: 6 gal.
  • Runtime: 7.5 hrs. (1/4 load on gas), 14.5 hrs. (1/4 load on propane)
  • Outlets: 120V 30A (TT-30R), 120V 20A Duplex (5-20R), 12V DC
  • Starting system: recoil, electric
  • Noise level: 59 dB(A)

Warranty: 3-year limited


This versatile dual fuel inverter generator from Champion is an all-around performer. The generator is capable of putting out 3,100 watts of continuous power on gasoline or nearly 2,800 watts on propane, making it ideally suited for powering essentially household appliances during an outage or for running a small-to-medium-sized RV. To make running an RV easier, the generator even comes with a 30-amp RV-ready outlet so you can plug your vehicle’s grid directly into the power source. Be aware for other uses, though, that having just two 120-volt power outlets can be somewhat limiting.

Despite the somewhat larger power capacity of this generator, it doesn’t compromise on portability. The generator is surprisingly small and lightweight, and is mounted on a set of hidden wheels so you can easily take it anywhere. For RV camping, the generator is quiet enough – 59 dB at 25% power output – that you won’t attract attention from your neighbors.

The main downside to this generator is that the runtime is somewhat short, especially when running on gasoline. The small 1.6-gallon fuel tank only holds enough gas to provide 7.5 hours of power at a 25% load – so if you try running the generator near its capacity you’ll run through the tank in just a few hours. However, if you run on propane you can connect multiple tanks so that you can run the generator for essentially as long as you like.

That said, the generator is reasonably priced and even comes with an electric starter to make life easier. There’s also a backup recoil starter in case the battery ever runs dead, so you won’t find yourself without power. To sweeten the deal, Champion includes a three-year warranty on this generator.

  • Dual fuel inverter generator
  • Reasonably priced
  • RV-ready outlet
  • Relatively quiet for its power at just 59 dB
  • Mounted on stow-away wheels
  • Three-year warranty
  • Short runtime on gasoline
  • Only two 120-volt outlets


WEN 56310i-RVBest Inverter Generator for RV

  • Type: inverter
  • Fuel: gasoline
  • Rated/surge watts: 2,800/3,100
  • Engine: 212cc 4-stroke OHV
  • Fuel tank capacity: 1.85 gal.
  • Runtime: 7.5 hrs. (1/2 load)
  • Outlets: (2) 120V three-prong, (1) AC 120V 30A RV, (1) 12V DC, (2) 5V USB ports
  • Starting system: recoil
  • Noise level: 57 dB(A)
  • Warranty: 2-year

This medium-sized inverter generator from Wen is the perfect pairing for your next RV trip. The 3,100 watts of surge power and 2,800 watts of continuous power offer enough juice to power all of your basic RV appliances, including a refrigerator-freezer, microwave, and even a small air conditioning unit. On top of that, the generator comes with an RV-ready 120-volt 30-amp outlet so you can connect it directly into your RV’s power grid.

Users noted that the runtime on this generator is relatively short – just 7.5 hours at half-load – so you’ll need to keep a jerry can of fuel onboard your RV if you’re out for an extended trip. However, since most RV users only had the generator on in the mornings and evenings around camp, they didn’t find that their power was interrupted by having to add fuel to the tank.

What makes this generator even better for camping trips – as well as any other use – is that its relatively lightweight, compact, and quiet. The generator weighs just 80 pounds and is mounted on a small set of wheels so you can easily tow it around camp or home. While the design is boxy, this is precisely so that it can fit neatly into the generator compartment on the outside of most RVs. And when running at 25% load, this generator produces just 57 dB of noise so that it’s quiet enough to hold a conversation around and to not bother your neighbors at a campground.

In addition to the RV-ready outlet, this generator offers two 120-volt outlets and two USB charging ports for small electronics. The only other thing that users wished for was an electric starter, although few people reported having trouble with the recoil starter. Wen offers a two-year warranty on this generator for peace of mind.

  • RV-ready outlet and two USB charging ports
  • Relatively lightweight, compact, and quiet
  • Enough power for most RV appliances
  • Mounted on small wheels
  • No electric starter
  • Relatively short runtime

Pulsar PG4000iSRBest Generator with Remote Start

  • Type: inverter
  • Fuel: gasoline
  • Rated/surge watts: 3,500/4,000
  • Engine: 224cc 4-stroke OHV
  • Fuel tank capacity: 3.4 gal.
  • Runtime: 15 hrs. (1/4 load)
  • Outlets: (1) 120V 20A Duplex, (1) 120V 30A RV, (1) 12V DC 8A, (1) USB port
  • Starting system: recoil, electric, remote
  • Noise level: 63 dB(A)
  • Warranty: 1-year limited

This 4,000-watt generator from Pulsar is not only budget-friendly – it’s also one of the best choices if having a remote starter function is important to you. The remote start can be a major advantage during a power outage at home or for using the generator with an RV, since you don’t need to venture outside to turn the generator on. With those uses in mind, it’s important to note that the generator sports an RV-ready 120-volt 30-amp outlet and offers enough power to keep most RV and essential home appliances running. However, be aware that users found that this generator makes a loud whining noise when running close to its rated 3,500-watt power output.

The generator is also surprisingly portable for a 4,000-watt generator since it’s mounted on a set of small wheels and has a single carry bar across the top. Users also appreciated the telescoping handle, which makes it easy to carry this generator in tow around the house or campsite.

The downside to using this generator either at home or with an RV is that it’s somewhat noisy – it produces 63 dB of noise at a 25% load and gets even louder with its whine as you turn up the power. In addition, the fuel efficiency and runtime of this generator are not particularly impressive for the 4,000-watt inverter generator class. Pulsar’s model offers just 15 hours at a 50% load.

One other thing to keep in mind is that this generator only offers two 120-volt outlets in addition to the RV-ready outlet. Given the power output, many users would have liked to have additional outlets. However, the included USB port was a convenient addition for charging small electronics.

  • Remote electric start
  • Includes RV-ready outlet and USB outlet
  • Portable with telescoping handle
  • Relatively inexpensive
  • Noisy for its size class
  • Fuel efficiency and runtime are middle-of-the-road
  • Only two 120-volt outlets

Generac 7043Best Standby Generator

  • Type: standby
  • Fuel: propane, natural gas
  • Rated watts: 22,000 (LP), 19,500 (NG)
  • Engine: 999cc Generac G-Force 1000 Series
  • Fuel consumption: 92 ft3/h (LP, 50% load), 228 ft3/h (NG, 50% load)
  • Starting system: automatic
  • Noise level: 57–67 dB(A)
  • Warranty: 5-year limited

This standby generator from Generac is specifically designed to keep your home running without a hitch in the event of an extended power outage. The generator is outputs 22 kilowatts of power when running, which ensures that even medium to large houses won’t exceed the capabilities of this generator. While you can fuel the generator with propane for short-term outages, the generator can also be connected to your home’s natural gas supply line during installation to ensure that you have a nearly limitless fuel supply and runtime.

Importantly, this standby generator is one of the quietest on the market today. When running at a 25% load, it produces just 57 dB of noise – virtually ensuring that your neighbors won’t even notice you have a generator running. The monthly power cycles in the generator are even quieter.

The main catch to this generator is that it’s quite an investment. On top of the cost of the generator itself, you’ll need to pay to have it installed and connected to your home’s natural gas lines. Plus, since the generator only produces 240-volt power, you’ll need a step-down transformer to connect it to your home’s power grid – and installing that will require most people to hire an electrician.

That said, the generator’s price does include a 200-amp smart transfer switch, which allows you to seamlessly and safely switch between grid and generator power when an outage occurs. In fact, the smart switch will automatically turn the generator on when the power goes out and you can even get an alert on your phone that your generator has turned on. On top of that, Generac provides a five-year warranty on this generator.

  • 22-kilowatt standby generator
  • Runs on propane or natural gas
  • Includes 200-amp smart transfer switch with mobile app
  • Extremely quiet for a standby generator
  • Five-year warranty
  • Expensive
  • 240-volt output requires a step-down transformer

DuroMax XP12000EHMost Powerful Portable Generator

  • Type: conventional
  • Fuel: gasoline, propane
  • Rated/peak watts: 9,500/12,000 (gas), 8,075/10,200 (LPG)
  • Engine: 457cc 4-stroke OHV Forced Air
  • Fuel tank capacity: 7.9 gal.
  • Runtime: 10 hrs. (1/2 load, gas), 20 hrs. (1/2 load, LPG)
  • Outlets: 120V 20A, 120V 30A, 240V 30A, 240V 50A
  • Starting system: recoil, electric
  • Noise level: <74 dB(A)
  • Warranty: 3-year (residential), 1-year (commercial)

For the most demanding on-the-go power needs, there are few solutions better than this generator from DuroMax. The generator is rated to output an incredible 12,000 watts of surge power and 9,500 watts of continuous power. That’s more than enough to power most appliances in your home during an outage, as well as to power a massive work site or large RV. Even better for homeowners and contractors, the generator offers the ability to draw 240-volt power through one 30-amp and one 50-amp outlet for powering the most heavy-duty tools and appliances.

Another major advantage to this generator is that it’s a dual fuel generator, so you can use either gasoline or propane with it. The ability to use propane can be a major cost-savings measure over the long-term, since this generator unsurprisingly guzzles fuel. When running on gasoline, the generator runs through nearly eight gallons of gas in just 10 hours at half-load.

This generator is about as loud as you’d expect – 74 dB at 25% load – but compared to other behemoth generators it’s actually relatively quiet. You’ll still likely want ear protection if you’ll be working in the vicinity of the generator, though. In addition, despite the size of this generator, it is portable by teams of two to three. The generator is heavy to lift, but is mounted on large pneumatic tires so that you can easily tow it from your truck to your worksite or around the house.

Keep in mind that while users found this generator to be relatively reliable over the course of a few years, durability is an issue with any generator this large. DuroMax offers a strong three-year warranty for residential users, but drops that warranty to just one year for commercial users – a major disincentive for contractors to opt for this model.

  • Extremely powerful portable generator
  • Dual fuel generator
  • Offers 240-volt power through two outlets
  • Quieter and more portable than competitors
  • Three-year warranty for residential users
  • Commercial users only get one-year warranty
  • Voltage display is analog and somewhat hard to read
  • Power output on propane not specified

Goal Zero Yeti 1400 WiFiBest Solar Generator

  • Type: Lithium power station
  • Battery: lithium-ion (NMC)
  • Capacity: 1,425Wh
  • Rated/peak watts: 1,500/3,000
  • Outlets: (1) 120V AC inverter, (1) 12V DC, (1) 5V USB-A, (1) 5V USB-C, (1) 5V USB PD port, (1) 12V Power Pole Port
  • Dimensions: 10.1 x 15.3 x 10.4 in
  • Weight: 43.7 lbs
  • Warranty: 1-year

The price tag on this solar-capable generator from Goal Zero may be the first thing you notice, but don’t stop there. This generator is generously loaded with outlets and modern features like an LCD display, plus it makes absolutely no noise since it lacks the engine of a traditional generator.

The generator’s 1,425 watt-hour lithium-ion battery can be charged either from a set of solar panels (sold separately for several hundred dollars depending on size) or directly from your home’s power outlet. Once charged, the battery can power a standard refrigerator for nearly 24 hours, charge a laptop 23 times, or an LCD TV for 14 hours. Don’t expect to run heavy-duty tools and appliances off this generator, though, since it’s only rated to 1,500 watts of continuous power. Having 3,000 watts of surge output is helpful, but somewhat unnecessary given the lower continuous power rating.

The nice thing about this generator is that since it’s essentially a battery station, it doesn’t make any noise and doesn’t require any maintenance. You don’t need to buy gasoline to run it, either, and with a set of solar panels you can recharge it as you use it. It’s also extremely lightweight, at just 43 pounds, and relatively compact.

When it comes to outputs, this generator has everything you could possibly need. It has two 120-volt outlets, two standard USB charging ports, and two USB-C ports for newer devices. The LCD screen allows you to monitor how much power the solar panels are producing compared to how much power you are drawing from the battery, and even calculates a remaining battery life for you. Users also liked that the generator is WiFi-capable so that it can be controlled and monitored through a smartphone app.

  • Solar-powered rechargeable battery
  • Makes no noise and requires no fuel
  • Two USB-C ports for newer devices
  • LCD screen for monitoring input and output
  • Controllable via smartphone app
  • Very expensive relative to output
  • Solar panels not included
  • Only one-year warranty
  • Only 1,500 watts continuous output
  • Type: inverter
  • Fuel: gasoline
  • Rated/surge watts: 1,700/2,200
  • Engine: 80cc OHV
  • Fuel tank capacity: 1.2 gal.
  • Runtime: 10.75 hrs. (1/4 load)
  • Outlets: (1) 120V 20A 5-10R Duplex, (1) 1.5A 5VDC USB port, (1) 12VDC
  • Starting system: recoil
  • Noise level: not specified
  • Warranty: 2-year limited (residential), 1-year limited (commercial)

This relatively inexpensive inverter generator from Generac is a versatile choice for anyone whose power needs and budget are modest. The generator is capable of producing 2,200 watts of surge power and 1,700 watts of continuous power – enough for powering basic tools around the yard or for adding power to your next camping trip.

The generator is lightweight and portable, weighing just 47 pounds. While users found that the single carry handle is comfortable for short distances, the lack of wheels can become annoying if you need to frequently move the generator when filled with gas. While the noise output of this generator is not specified by Generac, users found that it is on par with other 2,000-watt inverter generators and that you can easily hold a conversation over the generator up to half-load.

The disadvantage of this generator compared to a more expensive alternative is that the engine is relatively inefficient and the gas tank is small. The generator runs for just 10.75 hours at a 25% load, essentially requiring you to turn the generator off, wait, and refuel it every few hours for most uses. Depending on your application, this can be a major limitation.

In addition, the warranty on this generator is relatively short, at just two years for residential users and one-year for commercial users.

That said, the outlet panel on this generator is nicely equipped with a pair of 120-volt outlets, a 12-volt DC charging port, and a USB charging port. The two 120-volt outlets have simple reset buttons so it’s easy to reset the generator without turning it off in the event of a short.

  • Lightweight and portable inverter generator
  • Noise level is reasonable
  • Budget-friendly
  • Includes USB charging port
  • Short warranty, especially for commercial users
  • Fuel efficiency could be better

Honda EU3000ISBest Quiet Portable Generator

  • Type: inverter
  • Fuel: gasoline
  • Rated/surge watts: 2,800/3,000
  • Engine: 196cc Honda GX200
  • Fuel tank capacity: 3.4 gal.
  • Runtime: 20 h (1/4 load)
  • Outlets: 20A 125V Duplex, 30A 125V Locking Plug, 12V DC
  • Starting system: recoil, electric
  • Noise level: 50–57 dB(A)
  • Warranty: 3-year (residential and commercial)

This incredibly quiet inverter generator from Honda is perfect for when you need power without the typical loud engine noises. The generator produces up to 3,000 watts of surge power and 2,800 watts of continuous power, enough to cover most essentially appliances like a refrigerator, freezer, television, and air conditioner all at the same time. Better yet, it does this while producing a maximum of just 57 dB of noise. For comparison, the similarly powerful Wen generator produces 57 dB of noise at a 25% power load.

On top of that, Honda built this generator to run for long periods. The hefty 3.4-gallon fuel tank is significantly larger than the average for this class of generators and allows the engine to run for up to 20 hours at a 25% load. That’s a huge difference if you need all-day power, since most other generators will require you to stop and refuel in the middle of your work.

One thing that users didn’t love about the design of this generator is that it is bulky and heavy, but doesn’t come mounted on wheels. While there are two lift bars on either side of the generator, these are better suited to a two-person lift than to a single person trying to move the generator.

In addition, while users appreciated the included electric start, the generator is somewhat lacking in additional outlets. There are no USB ports, only two 120-volt outlets, and one 30-amp locking outlet.

Still, users felt that the high price of this generator is somewhat justified by the extremely fuel-efficient and reliable Honda engine, which comes with a three-year warranty.

  • Extraordinarily quiet for its size
  • Very long runtime
  • Up to 2,800 watts of continuous power
  • Electric starter
  • Three-year warranty on reliable Honda engine
  • Very expensive
  • No USB ports
  • Difficult for a single person to transport
  • Type: inverter
  • Fuel: gasoline
  • Rated/surge watts: 3,500/4,200
  • Engine: 212cc OHV 2-stroke
  • Fuel tank capacity: 2.6 gal.
  • Runtime: 18 hrs. (25% load), 15 hrs. (50% load)
  • Outlets: (2) Duplex 120V 20A GFCI (5-20R), (1) 120V 30A (TT-30R), (2) 5V USB ports
  • Starting system: recoil
  • Noise level: 62 dB(A)
  • Warranty: 3-year limited (residential), 1-year limited (commercial)

This 4,200-watt generator from Westinghouse keeps its price tag reasonable by blending the features of a conventional gasoline generator and an inverter generator. Unlike most modern inverter generators, the engine is not fully covered – which does contribute to this generator making slightly more noise than necessary and leaves open the possibility of burning yourself on hot engine parts. In addition, the 212cc engine is a two-stroke, rather than a more efficient four-stroke engine like those used on most inverter generators. It also cannot be run in parallel like most inverter generators. Still, the generator is completely safe to use with sensitive electronics.

This hybrid design has some interesting advantages and drawbacks. On the one hand, the generator is able to produce up to 3,800 watts of continuous power – which is at the output limit of today’s consumer-friendly inverter generators. It also has an extremely long 15-hour runtime at 50% load, which users who need a generator for all-day power production appreciated.

On the other hand, the Westinghouse generator is somewhat noisy compared to competitors, producing 62 dB of noise at a 25% load. When running at full power, it will sound comparable to a conventional generator.

Users liked that the generator comes with a fully-featured outlet panel, including a pair of USB charging ports and a 120-volt 30-amp twist-lock outlet that can be adapted for use with an RV. There’s also a small LCD display that shows the wattage being drawn from the generator and the remaining runtime.

Keep in mind that while residential users receive a lengthy three-year warranty with this generator, commercial users are limited to a one-year warranty.

  • Inexpensive but powerful inverter generator
  • 15-hour runtime at 50% load
  • Two USB ports and 30-amp locking outlet
  • LCD display
  • Three-year warranty for residential users
  • Hybrid design uses less efficient two-stroke engine

Diesel generators like this model from DuroStar are designed to be both powerful and virtually indestructible – a potent combination for home users who need a generator that can stand up to extended power outages. This generator offers 5,500 watts of continuous power and 6,000 watts of surge power. That’s enough to allow you to run most of your household appliances as you normally would, as long as you’re careful about additional power loads like a washer, drier, or dishwasher. Plus, the generator can run for up to 12 hours at 50% load, so refueling is hardly an issue.

Users also appreciated the diversity of outlets on this generator for pairing with a wide variety of home appliances. The generator comes with a pair of standard 120-volt outlets, a 120-volt 30-amp outlet, and a larger 240-volt 30-amp outlet that can be used for heavy-duty appliances like an air conditioner. Even better, users took advantage of the remote electric start so that they didn’t even need to go outside to start up the generator in the morning or evening.

The downside to diesel generators in general is that they are quite loud and relatively expensive up front. The DuroStar generator produces 78 dB of noise at a 25% load – so you’ll need ear protection when you approach it at higher loads and you’re almost certain to draw complaints from your neighbors if you run it at night.

However, the upside to this generator is that it can be fixed indefinitely at a far lower cost than any portable generator and is much more resilient in the face of extended periods of use. To back up your generator, DuroStar provides a three-year warranty.

This small generator from DuroStar is designed to compete with the myriad of portable gasoline generators on the market. But where gasoline generators wear down over time, users note that this model can run for decades with minimal maintenance.

The generator is relatively powerful, producing 3,300 watts of continuous power or 4,000 watts of surge power. That makes it a great choice for everything from worksites to RV trips to home use. However, keep in mind that the eight-hour runtime at half-load can be somewhat limiting since you won’t get a full day’s worth of power under most circumstances.

The outlet panel on this generator offers few frills, but it does offer everything users wanted including an analog display of the wattage being drawn from the generator. The 120-volt 30-amp outlet is not RV-ready, but it can be easily used to connect to an RV’s power grid with the addition of an adapter.

The downside to this generator is that it’s very loud, especially when compared to similarly powerful inverter generators like those from Honda or Wen. The DuroStar generator produces 69 dB of noise at a 25% load, which is already loud enough to prohibit conversations and draw complaints from neighbors at a campsite. When the generator is running at full power, users warn that it’s worth having ear protection available.

When it comes to price, this probably isn’t the cheapest generator on the market – but it is one of the most cost-efficient. That’s because you can balance the lifetime cost of this generator – which will last for years and comes with a three-year residential warranty.

Buying Guide

Now that you’ve learned more about our 12 overall favorite generators on the market today, how do you choose between them to find the generator that’s right for your needs? In our buying guide, we’ll cover the differences you need to know about between different types of generators, fueling options, and features, as well as answer some frequently asked questions about generators.

Generator type

There are different types of generators for different needs. If you need power just at home, for example, you might be better suited by a stationary standby generator than a portable generator. Similarly, the types of appliances and electronics you plan to power can determine whether an inverter or conventional generator is better suited to your needs.

Portable or standby?Top 12 Generators for Any Budget and Purpose – Reviews and Buying Guide

The first choice you need to make is whether a portable or standby generator is best for you. A standby generator is typically designed to power most or all of a house’s electricity needs during a short-term or extended power outage. Because of this, standby generators are typically found in storm-prone areas where long outages are common. These generators are stationary, installed outside the home, and may be connected to a natural gas line to allow for unlimited fuel sourcing in the aftermath of a storm. Compared to portable generators, standby generators typically put out far more wattage – greater than 10 kilowatts – and produce very little noise.

Portable generators are more versatile and can be used for anything from camping and RVing to outdoor parties and powering your home during an outage. Portable generators come in a huge variety of shapes, sizes, and power ratings to cover the widest range of needs, but it’s important to keep in mind that some portable generators are easier to transport than others.

Inverter or conventional?

Conventional generators produce AC electricity directly from their engines, which can then be used to power appliances and tools. However, this AC electricity is relatively “dirty” – it can damage sensitive electronics like smartphones, computers, and anything with a microchip.

Inverter generators take that AC electricity and then convert it to DC power and back to AC electricity. This essentially cleans the electricity, reducing the overall distortion of the electrical waves so that it is safe to use with sensitive electronics. In addition, inverter generators use microcontrollers around the engine that allow them to be much more fuel efficient compared to conventional generators.

If you have multiple inverter generators, you can connect them in parallel to increase your power output.

However, there are some drawbacks to inverter generators. They tend to cost more than conventional generators, although that price gap is closing as the technology further improves. In addition, inverter generators are currently limited to a maximum power output of about 4,000 watts – if you need more power than this, you’ll need to choose a conventional generator.

How much power do you need?

Once you’ve decided what type of generator you need, the next thing to determine is how much wattage you need. Generators range from small portable generators offering less than 2,000 watts of power to massive portable generators like the model from DuroMax that offer up to 12,000 watts. Standby generators like the model from Generac offer yet more power – over 20 kilowatts.

The best way to determine how much power you need is to add up the wattages of all the appliances and tools you expect to run at a single time. This number needs to be less than the continuous wattage of your generator. If you have motor-driven appliances like a refrigerator, freezer, or air conditioner, you’ll also need to consider the start-up power requirements of these appliances. When starting, the wattage cannot exceed the surge wattage of your generator.

Keep in mind that it’s easier to opt for a larger than necessary generator initially than to increase your available power later. In addition, the closer you run your generator to its rated power output, the faster you’ll run through fuel and the more noise the generator will produce.

It’s always a good idea to choose a generator that is slightly larger than you calculate that you need.

Fuel options

When it comes to portable generators, gasoline is the most common fueling option. However, dual fuel generators like the models from Champion and DuroMax can run on either gasoline or propane. Propane is often less expensive than gasoline, but you’ll get slightly less power out of your generator when running on propane because it’s a less energy-dense fuel. That said, propane offers the advantage that you can run your generator more or less continuously by switching propane tanks out on a single fuel line.

Although more expensive and less common, some portable generators like the model from DuroStar can run on diesel fuel. These generators tend to be virtually indestructible and are more immune to the frequent price shifts around standard gasoline.

Finally, some tri fuel portable generators and many standby generators can run on natural gas. Natural gas is less energy-dense even than propane, so you’ll see some power loss when running your generator on natural gas. However, natural gas is by far the cheapest fuel option and is virtually unlimited if you tap into your home’s natural gas line. This is a major advantage for standby generators, since natural gas lines often continue to provide fuel even during extended power outages and in the aftermath of major storms.

Generator fuel tank capacity and runtime

Top 12 Generators for Any Budget and Purpose – Reviews and Buying GuideThe capacity of your generator’s fuel tank and the efficiency of the engine combine to determine how long you can run your generator for in one go. The fuel tank capacity is typically measured in gallons and can vary widely even between generators in the same size class. The runtime is measured in hours, usually at a 25% or 50% load.

If you are always planning to run your generator on gasoline, runtime can be extremely important. For example, a generator with a long runtime like the model from Yamaha can allow you to generate power for an entire day of work, or an entire evening in your RV or campsite. On the other hand, a generator with a small fuel tank and limited runtime can require that you turn off the power every few hours, cool down your generator, and then refuel.

Keep in mind that for dual fuel generators running on propane, it’s possible to extend the runtime simply by using a larger propane tank or by connecting multiple propane tanks to a stopcock valve. If you are running a tri-fuel generator or a standby generator on a natural gas line, the runtime may be extended up to several days.

Safety features

Modern generators are equipped with several important safety features that protect both you and your generator. The first of these is a low-oil shutoff – every portable generator that we reviewed will automatically shut itself down before it runs out of oil. This protects the engine from irreversible damage as well as power surges that could occur if the engine were to fully run out of oil. Nearly all generators also have a low oil warning light so that you know ahead of time to turn the generator off.

The other important safety feature that generators have is overload prevention. Generators will automatically shut themselves down if you exceed their surge power at all, or if you exceed their continuous rated power for more than a few seconds. This prevents the engine from overheating, which can essentially melt important components of your generator and poses a dangerous fire hazard.

Ease of use

Another important thing to consider when choosing a generator is whether it has features to make it easier to use. Many inverter generators offer electric starters in addition to the standard recoil starter, and some, like the model from Pulsar, offer remote starters so you don’t even need to leave the house to start your generator. Other generators, like the DuroMax model, offer voltage meters so you can keep an eye on how much power you’re drawing and whether you are close to overloading the generator.

Another important ease of use feature to consider is whether your generator has a drain on the carburetor. This feature makes it significantly easier to drain fuel out of the generator ahead of a long storage period, which is important so that you don’t end up with stale fuel in your engine.

If you don’t have a drain, you’ll need to run your generator dry – which isn’t good for the engine over the lifespan of the generator.

Noise level

The amount of noise that a generator makes can be a big factor in where and when you can use it. For example, a noisy generator might not be a problem at a construction site, but if you’re camping or trying to run your generator outside your house at night you’re likely to draw complaints from your neighbors.

In general, inverter generators are quieter than their conventional counterparts and smaller generators make less noise than larger generators. Keep in mind also that generators typically produce more noise as you push them closer to their rated wattages.

When choosing a generator based on noise, it’s important to think about whether your application requires an ultra-quiet generator. Generators like those from Yamaha and Honda are priced at a significant premium specifically because they are among the quietest generators on the market in their respective power classes – so you’ll need to consider whether that added price is worth it for you.


Not all portable generators are equally portable, so it’s important to think about the size and weight of your generator and whether it is mounted on wheels. Lightweight generators like the portable model from Generac may not have wheels, but this isn’t a problem since a single person can easily carry it. On the other hand, a massive generator like the model from DuroMax may require two or three people to lift it in and out of a vehicle – even though it is mounted on wheels to make transporting it the rest of the way easier. Consider where you’re likely to use your generator, how you plan to get it there, and whether you can lift the weight of your generator by yourself.

Warranty and customer serviceTop 12 Generators for Any Budget and Purpose – Reviews and Buying Guide

All of the generators we reviewed are built to last, but having a warranty from the manufacturer can provide significant peace of mind. Manufacturers’ warranties range from just one year, as for the Pulsar generator, to up to three years for most other portable generators. Warranties for standby generators are often five years or longer. Keep in mind that many manufacturers limit the warranty for commercial users since the generator is assumed to see more frequent use.

Customer service is also an important component of having peace of mind after your generator purchase. Companies like Generac and Champion are beloved by customers for their support – Champion offers lifetime technical support for many of its generators – which makes it much simpler to file a warranty claim in the event that anything goes wrong with your equipment.

Generator prices

Generators cover a huge range of prices depending on whether you are looking at a portable or standby generator, an inverter or conventional generator, or a small or large generator. On the inexpensive end of the spectrum, a generator like the DuroStar model costs under $300. Yamaha and Honda generators typically cost the most because of their premium engines – the Honda generator costs over $2000. Standby generators also tend to be large investments, costing in the several thousands of dollars depending on the exact model.


Maintenance is the most important thing you can do to ensure you get a long life of work out of your generator. There are two critical things you should always do to make sure your generator runs smoothly.

The first is to change the oil relatively frequently. You should change the oil in your generator after the first 20 hours of use, and then every 50–100 hours of use after that. Keep an eye out for the low oil light – if you see this come on, you should power down the generator immediately to prevent engine damage. It’s always a good idea to keep fuel and filters on hand with your generator when you’re using it or travelling with it.

The second thing you need to do to protect your generator’s engine is to prevent fuel from going stale inside your generator. Before you put the generator away for a long storage period, be sure to fully empty the gas tank and drain the carburetor of any remaining fuel. If your generator does not have a carburetor drain, you’ll need to run it dry to remove the leftover fuel. Be sure to always fill your generator with fresh fuel after the storage period, as well.

Beyond that, there are some important safety tips to keep in mind when using your generator. Always allow it to cool down before adding more fuel to the tank – adding fuel to a hot generator is a dangerous fire hazard. In addition, never backfeed your generator. If you plan to connect your generator to your home, you need to invest in a transfer switch and take the time to safely hook up your generator to your house’s electrical grid.


You can use any generator with your RV, but you’re likely to be best served by a generator that has a 120-volt 30-amp RV-ready outlet. This outlet allows you to connect your generator directly to your RV’s power grid, so that you can power all of the outlets in your RV in one connection. Without an RV-ready outlet, you’ll need to run cords from your RV appliances out to your generator’s 120-volt outlets.

Gasoline is the most efficient fuel since it’s the most energy-dense, but it’s also the most expensive. In addition, your runtime on gasoline is limited by the size of your generator’s fuel tank, which is often quite small. Propane is less expensive and you can connect two tanks two a stopcock valve to keep your generator running for extended periods. However, you’ll see a decrease in rated power output on most dual fuel generators when running on propane.

Typically, the amount of time you can run your generator continuously is determined by the size of the fuel tank and the efficiency of the engine. You should never fuel up the generator while it’s running, so you’ll need to turn it off when the fuel runs out. But, if you’re using a continuous supply of propane or natural gas, heat build-up is the main concern. Depending on how well ventilated your generator is, you may be able to run it for up to 24 hours at a time.

Yes! Typically, the easiest way to use a portable generator during a power outage is to run extension cords from your appliances to the generator outlets. If you want to connect your generator directly to your home’s electrical grid, you’ll need to invest in a transfer switch.
