What a 500 Wh power station runs

Nonstop runtime for one device at a time across the 7 models in this class, at 85% inverter efficiency. “Models that can run it” counts those whose output and surge cover the device, including a few that don’t publish a surge rating and may not start a motor.

Questions

How long does a 500 Wh power station run a fridge?
Between about 7.5 hours and 11 hours nonstop for a typical ENERGY STAR full-size fridge (58 W average), depending on the model. 4 of the 7 models here can start one. See the fridge page for older and larger fridges.
What can’t a 500 Wh power station run?
Only some can run a refrigerator (4 of 7) and drip coffee maker (2 of 7). The table above shows which ones, and the runtime calculator checks any device against any model.
Is 500 Wh the right size for me?
Battery size decides how long, and output decides what. List your own devices in the size finder to see which class you actually need, with a safety margin for battery aging and cold weather.
