What is a portable power supply? When do you need one?
A portable power supply is very much like a generator. They provide you with electrical power when you are camping or if the power is out in your home. There are a few differences, however, between a portable power supply and a generator. First of all, a generator runs on gasoline, while a portable power supply runs off of a rechargeable battery. It is necessary to charge a portable power supply before you use it, or it will not be able to run.
Another big difference between a portable power supply and a generator is their noise level. While generators can be extremely noisy, which makes them less than ideal for camping, portable power supplies are completely silent. No matter how much you have charging off of one, they will not make a sound.
Finally, generators put off fumes, since they use gasoline as their power source. This makes them a bit trickier to use in close quarters since the fumes could be dangerous in a closed space. Even in an outdoor capacity, these fumes can be a real bother. A portable power supply, on the other hand, will not put off any sort of fumes, making it an ideal source of power both inside and out.
It’s never a bad idea to keep an extra source of power handy. If you are going to be going camping for an extended period, then these products are good to bring along. They will help to keep all of your most essential devices charged and ready for use.
They work just as well in the home if the power goes out. While they aren’t quite powerful enough to keep a whole house running, they can be used to charge up your cell phone, tablet. In the case of some of the larger models, such as the SUAOKI Portable Power Station
, they can be used to run the lights in your home until the main power is back on.
Features to consider before buying
In this section, we will cover all of the different details that you need to keep straight to make sure that you get the right power supply for your needs.
Battery capacity and type
The first thing that you will need to take into account is the battery capacity and the type of battery that you want your power supply to utilize. The easier of these two questions to answer is the battery type. The only battery type that you should even consider is a Lithium Ion option. This battery type is easy to recharge, can hold a charge for a long time, and has a long life. This makes them ideal for use in a power supply, and we highly recommend them.
As far as the capacity goes, it is very much up to you and what you intend to use the power supply to charge. The higher the capacity, the more devices you will be able to run off of the supply. This will also cost a bit more than if you went with a smaller capacity battery. Then you will only be able to charge a limited amount of items, which might cause a problem in an emergency situation.
The amount of wattage or voltage that your power supply is rated for will determine what you can run off of it. If it has a lower output, then it can only be used with smaller devices, as well as a limited number of devices at the same time. On the other hand, the higher the output, the more you can run off of your supply at any one time. You would also be able to run larger devices, such as lights or fans if the output were high enough.
For instance, if you want to charge a laptop, you would need a power supply that could run about 60-90 watts, which even a smaller power supply like the EWEMOSI AC Outlet Portable Laptop Power Bank could handle with no problem. If, however, you want to run multiple items off of the same power supply, you are going to need one with higher maximum output.
Number of outlets
Once again, what you intend to use your power supply for will greatly determine the number of outlets that you need to have. If you are only going to be charging one or two items off your supply, then you can probably get by with one or two outlets.
If, however, you are going to be using your power supply for large gatherings, such as camping trips, you will want to have more outlets. That way, everyone can get in on the charging action, and no one’s devices will be left to lose power.
Type of outlets
The types of outlets that your power supply can accommodate are, once again, up to your personal preference. If you are only going to be charging a laptop or just want to power a desk lamp, then you can get by with a few regular, AC plug-in outlets.
If, however, you want to make things a bit easier on yourself, then it might not be a bad idea to get a power supply with a variety of plug-in options. This would include USB plugs, as well as DC ports. That way, you are covered, no matter what you need to plug in and charge.
No matter which portable power supply you end up settling on, you want to be sure that there are multiple charging options available to you. That way, you will always be able to keep it charged and ready for use, no matter the circumstance.
There are several different power source options available to you. These include standard AC plugins for home charging, DC plugins for your car, and even solar options. The only problem with solar is that you will usually need to purchase an additional solar panel to actually use this option.
Warranties on power supplies do not, as a rule, last too terribly long. At best, you will only be able to get one for about 18 months, with many being only a year in length. You want to make sure that whatever type of warranty you get will cover the most expensive part of the device, which is the battery.
There are several other features that, while not essential to the main function of the power supply, are still nice to have. These might include things like flashlights, hazard lights, battery indicators, and output meters.
Two of the better extra features to keep in mind are an overheating protection system, as well as a surge protector. These two features will help to make sure that you power supply doesn’t sustain any damage due to heavy use.
