Never use a portable power station to run high-power devices for long periods of time or any device that exceeds its output capacity. When you don't need something as powerful as the Jackery Explorer 1000, look for a mid-range portable power station with a capacity of approximately 500 watt-hours. But you can charge your portable power station overnight in a wall outlet (charging most of them from empty to full takes 12 to 24 hours), store it in a trunk with the rest of your equipment, and carry it with you keeping your phone, laptop, camera, projector, GPS unit, breast pump, drone or other electronic device powered for hours at a time. Every company that sells portable power plants provides the expected amount of watt-hours that its products are supposed to last.
I put each battery to the test and considered factors such as battery life, wattage, power output, the type of charging ports the power plant offered (at least one USB port was a must) and more. Then, my accountant husband helped me convert every decimal into the expected operating time of each power plant. While each power station provides mobile power in a compact design, each portable generator has a different design and range of features. It is still the best seller in portable power plants on Amazon and that is due to its excellent customer support.
A portable power station is the best option if you need to use common personal electronics and small appliances while you spend long periods of time away from home AC outlets, or if you want to have backup power ready to go in an emergency. They can also provide backup power during a power outage when you need to keep your phone turned on or an essential device running. For example, most laptops only need 100W to charge at full speed, a portable cinema projector consumes about 150W, and a portable washing machine requires about 350W. If you have a short-term power outage and only need to power your refrigerator, a 200-watt-hour power station could keep you running for almost three hours.
If you plan to travel, keep in mind that, in most cases, portable power plants have to travel by land.
