Which power stations can run a window air conditioner?

Manufacturer specs for 8000 to 10000 BTU window air conditioners list cooling draws of 720 to 1020 W. Generator charts give higher running figures for 12000 to 13000 BTU units and add a compressor starting peak of 2800 to 7200 W.

Every station we track

Runtime = battery Wh x efficiency / 3,250 W (the highest sourced running figure) to 720 W (the lowest). "Check" means the station's surge rating is not published or the result depends on the model.

A window air conditioner runs a compressor and two fans, so its draw depends on its size and on whether the compressor is running. Manufacturer specifications for 8000 to 10000 BTU units list cooling draws of 720 W (Frigidaire FHWC083TC1) and 1020 W (GE ASV10AB). Generator sizing charts use more cautious figures for larger units: 1800 running watts and 2800 starting watts for a 13000 BTU unit in Champion's chart, and 3250 running watts plus 3950 additional starting watts for a 12000 BTU unit in Generac's.

The starting figure matters because a compressor motor draws a short surge each time it starts, and it starts again every time the thermostat calls for cooling. A power station needs both a continuous AC rating above the running draw and a surge rating that covers the start. Units with a variable speed (inverter) compressor are designed to ramp up rather than start at full load, but makers rarely publish a starting figure, so read the nameplate amps and leave headroom.

Runtime is the other question. The compressor cycles, so the average draw is below the running figure, but on a hot afternoon it may run almost without a break. Pick the smallest unit that cools the room, set the thermostat a few degrees higher, and size the battery for the longest stretch you expect the unit to run.

Runtime calculator

Runtime (hours) = battery Wh x inverter efficiency / load W

Efficiency is the share of battery energy that reaches the outlet. Where the maker does not publish it we use 0.85. Average W is for loads that cycle on and off, like a fridge; leave it blank to use running watts. Starting surge assumes one motor starts at a time. How the estimates work.
