What Will a 1000W Power Station Run?

A 1,000 W power station runs devices that draw up to 1,000 W, as long as their start-up surge stays under about 2,000 W. With a typical 1,000 Wh battery, that means about 21.3 h for a CPAP or 8.5 h for a TV. Calculate your own devices.

Watts or watt-hours?

Watts (W) tell you what a power station can run at one moment. Watt-hours (Wh) tell you how long it lasts. A 1,000 W station with 1,000 Wh runs a 100 W load for about 8.5 h, or charges a phone about 56 times.

What to know about this size

This is the most popular size for short outages and camping: about 15.5 h for a fridge, or two to three nights of CPAP use.
Check whether "1000" means watts or watt-hours. Many models with 1000 in the name store about 1,000 Wh but deliver 1,500–1,800 W.
Motors need headroom: a fridge or window AC can start on 2,000 W of surge, but a 1/2 HP sump pump (about 2,150 W to start) may trip it.
