What can a power station run?
One page per device: the real watts, the start-up surge, and how long each power station lasts. Times below are for a typical 1,000 Wh unit.
Run several devices at onceWhat a 1,000 Wh-class power station runs
Runtime = battery Wh × 0.85 ÷ the device’s average watts. The 0.85 covers inverter loss, and the average is lower than the running watts for devices that cycle on and off, like fridges and pumps. On the 7 units from 998–1,070 Wh we list, that ranges from about 35 min for an electric kettle to about 15 nights for a CPAP (no humidifier).

Estimates from a full charge with nothing else plugged in. CPAP rows count 8-hour nights. Real runtime depends on temperature, battery age and your model’s draw. Open a device for every station’s runtime and the sources behind its watts.
