Best Mid-Size Power Stations (500–1500Wh)
The best mid-size power stations from 500 to 1500Wh, ranked on our scoring, with fridge, microwave and CPAP runtimes worked out for every pick we name.
Power Stations
Every major portable power station ranked on battery chemistry, cycle life, inverter output, recharge speed and energy per pound, from 250Wh camping packs to 5kWh home-backup units.
We score power stations on the published specifications that decide what you get for your money over years of use: battery chemistry and cycle life, how much power it delivers, how fast it refills from the wall and the sun, and how much energy you carry per pound. We compare stations within the same capacity class. See the full method.
