What can you power with a 10,000-watt generator?
A 10,000-watt generator can power almost everything in your house, except the central heating. And this would only be because central heating requires close to 5,000 or 6,000 starting and running watts, which would leave little power for the rest of your appliances, considering you need 5,000 to 7,000 watts to power basic appliances in an average-sized home.
Otherwise, it will comfortably power a sump pump, refrigerator and freezer, space heater, humidifier, furnace fan blower, microwave oven, TV, desktop or laptop, laser printer, security system, and lights.
If using it at a job site, you can connect an electric lawn mower, pressure washer, chain saw, circular saw, electric drill, string trimmer weed trimmer, paint sprayer, disc sander, hand drill charger, and halogen work lights. You can also connect an RV.
Important features to consider before you buy a 10,000-watt generator
Below, we explain each of the features that are important in a generator.
Rated and maximum power output
The rated power is the amount of power the generator can handle under normal load. In other words, it can handle any amount of power up to the indicated rated amount. Feeding a higher amount of power than the rated amount into the generator can cause overloading and may cause the generator to malfunction or get damaged.
The maximum power refers to the additional wattage the generator uses at startup and occasionally when running at the highest level of consumption. Maximum power is also referred to as peak power. Note that maximum power is only used for a few seconds at a time, while rated power is consistent and continuous throughout the period the generator is in operation.
Both power ratings (rated and maximum) will be indicated among the generator's specs, so be sure to check what these are before buying.
The engine is the power behind the generator. The more powerful the engine is, the more efficient the generator will be. Generator performance may not always correspond to the engine size, but in many cases, a big engine means a better performing generator. A good example of a generator that confirms this statement is the HONDA EB10000. It has a massive engine and is one of the best performing generators you can buy. Again, some engines may be smaller but more powerful. The best way to gauge how good the engine is is by checking the rated power and peak power it supports.
Fuel tank capacity
The bigger your generator's fuel tank, the longer it will run without you having to stop and refill. If you choose a generator with a small fuel tank capacity, it means you'll have to top off your fuel more frequently than someone whose fuel tank is bigger. If you'll be using the generator for short periods of time, this may not be a problem. But if you expect the generator to run for more than 10 hours a day, it may be a little inconveniencing. Some people don't mind the frequent refills as long as the generator's performance is exceptional.
How long will the generator run before the fuel reserve is exhausted? Seven to eight hours is considered good enough. Some generators deliver slightly less than this, while a few give as many as 11 hours in runtime. A good example is the Pulsar PG10000B16 which has a runtime of 12 hours. DuroMax XP10000E and JDNA Gentron GG10020C generators are other good performers with 11 hours of runtime each. Choose a generator with a longer runtime if you intend to run it for long periods at a time.
Most generators come with numerous 120V outlets, a 120V/240V twist-lock outlet, and a 12V DC outlet. This makes it possible to power a diverse range of products. If a generator does not have a 12V DC outlet or a 240V receptacle, it means you can only power smaller appliances and cannot charge your batteries.
Gasoline generators overall tend to be noisier than propane generators. Generally, though, most portable generators have a noise level that's between 72 dBA and 80 dBA. Choose a quieter generator like the DuroMax XP10000E if you're keen not to disturb the people inside the house, if you'll be connecting your RV, or if your neighbors are only a short distance away. You don't want to be a nuisance in the neighborhood. If the distance between houses is great and the noise isn't likely to disturb anyone, or if you'll only be using the generator occasionally and for short periods, you can go for a louder generator, especially if its performance is remarkable.
Size, weight, and portability
If you'll be moving the generator around frequently, choose a model that isn't too bulky or heavy. No one expects you to lift the generator – it wouldn't be safe to do so considering most of them weigh more than 200 pounds – but it should have good quality wheels and fold down handles to make transporting it easy. A lot of the 10000-watt generators in the market have these, so it's a matter of choosing the best wheel kit and how easy each one moves.
You can't afford to buy a generator without a warranty. Even at their lowest prices, generators are costly and call for you to have some sort of back up from the manufacturer. Thankfully, all major generator manufacturers issue warranties, with validity periods ranging from 1 year to 3 years. Some manufacturers give different validity periods for parts and workmanship, so always confirm what's covered in yours and for how long.
Yes. The 10,000-watt generator is a high-capacity generator that allows you to power nearly everything in an RV. It will power your RV air conditioner, mini fridge and freezer, microwave, toaster, coffee maker, hairdryer, TV, laptop, and phone. Check the manufacturer's recommendations for RV use so that you don't veer off safe usage at any time.
The bigger a generator is, the louder you can expect it to be. Because of the amount of power a 10,000-watt generator gives, it will be louder than, say, a 3,000-watt generator. Some 10,000-watt generators are louder than others, so you have to decide how much noise would be too much for you and your neighbors. Noise levels for 10,000-watt generators range between 70 dBA and 78 dBA, which is slightly lower than average busy street and traffic noise.
Yes, you can, provided there are enough outlets to plug into. Each outlet, whether 110V or 220V, is designed to operate independent of the other, and this means you can safely plug multiple appliances into the 110V and 220V receptacles at the same time.
Our best pick is the Pulsar PG10000B16. It appeared well-balanced to us and offered all the benefits we were looking for without compromising on anything. That you can use both LPG and gasoline on the unit is a big plus, and the long runtime provides the kind of reliability you need when running a critical appliance. We also found the mid-range price tag acceptable for the kind of performance it gives.
At second place is the Honda EB10000, which we have to say, could easily take the top slot were it not for its steep price. Everything about this generator is premium, from the sturdy steel frame to the big and powerful engine, high-capacity fuel tank, built-in advanced technologies, and 3-year warranty. If money is not a hindrance, we'd say go for this one.
Our budget pick is the All-Power America APG3590CN. This is probably the lightest in its class, a quality that makes it highly portable. We like that it has many outlets, the 8.5-hour runtime, the volt and hour meter, the RV setting, the low price tag, and the fact that it's EPA and CETL-certified.
