Four matters needing attention before use Portable Power Station

1. They Can't Deliver Nearly as Much Power as Gas Generators
As with their gasoline-fueled counterparts, portable power stations require a transfer switch should you wish to power things such as your furnace, overhead lights, or any thing else in your home that's hardwired.
But while a recreational inverter generator would probably keep the TV and a few lights on for 8 to 13 hours on one tank of gas, you'd see anywhere from 3 to 9 hours of power, under the same circumstances, with a portable power station. And you won't be able to run, for instance, your power-guzzling well pump.

2. They Need Take A while to Charge
In our tests, most of these models require hours of charging (typically overnight) to provide you with a full battery and max runtime.
So—assuming you fully charged the battery before a predicted weather event—a portable power station could give you hours of electricity to run a refrigerator or another essential appliance.

3. Charging With Solar Panels Can Be Iffy and Lengthy
If you're dealing with an outage or you're otherwise off the grid, charging the power station via solar panels is your only option—and that's provided you have good sun and no obstructions. In our tests, we found that the solar panels can add to the runtime, but that might only amount to an extra hour or two of power with  larger appliances.

4. They're Not All That Portable
Portable power stations are about the size of an average microwave oven, but they're fairly heavy—most in our tests weigh more than 80 pounds.

That means you'll likely need an extra pair of hands to lift one into the trunk of your car. Some of the models come with wheels, but not all wheels are large in size, which makes rolling them across a lawn difficult.
