How long will a 1,000 Wh power station run a refrigerator?

About 22 hours for a top-freezer fridge at the ENERGY STAR median of 41.4 W average on a 1,070 Wh Jackery Explorer 1000 v2, using Jackery's 85% conversion factor. Older fridges use more.

How long will a power station run a CPAP?

A ResMed AirSense 11 at its 56.1 W typical figure runs about 16 hours on a 1,024 Wh Anker SOLIX C1000 Gen 2, roughly 2 8-hour nights. Humidifier settings change this a lot.

Power station runtime chart

Hours each station runs one appliance at a time, starting full. Every cell uses the same formula as our runtime calculator: capacity × usable share × 85% conversion ÷ (appliance average watts + idle draw).

How to read it

Fridges and freezers cycle, so their average watts are far below their running watts; the hours above already account for that. To run several things at once, add their watts in the runtime calculator or size a station for your list with Size a station. For a CPAP or oxygen concentrator, read CPAP and oxygen: read this first. Appliance pages: refrigerator, CPAP, Wi-Fi router.

The BLUETTI AC180 row uses BLUETTI's published 90% depth of discharge and 15 W self-consumption. Other makers don't publish these, so their rows use 100% and 0 W; real runtimes will be somewhat lower. Full method: Methods and sources.
