Running a coffee maker on backup power
The short answer
A coffee maker uses about 700–1,500 watts while running . Over 24 hours it uses roughly 336–2,880 watt-hours.
Buy for the higher number in each range. 49 of the 58 products we track can run it. For example, the Zendure SuperBase V6400 would run it for 3.6–7.8 hours.
The numbers behind that
Heating elements draw hard but briefly. The brew cycle matters for output sizing, not for energy.
What it draws while it is actually on.
How much of the hour it is actually drawing power. This is what turns running watts into energy.
Multiply the battery capacity you are considering by roughly 0.85 to compare like with like.
Plugs into an outlet
This appliance plugs into a normal socket, so a power station or a generator's outlet can run it directly.
