How many watts does a coffee maker use?

A coffee maker draws 1,200–1,500 watts while running, which is 10–12.5 amps on a 120 V circuit.

Coffee maker watts, amps and circuit

Typical power use of a coffee maker
Running watts	1,200–1,500 W
Voltage	120 V
Running amps	10–12.5 A
Circuit	standard 120 V outlet

Also called: keurig, keurig coffee maker, drip coffee maker, single-serve coffee maker.

What size generator runs a coffee maker?

A coffee maker needs a generator that supplies at least 1,500 running watts. A 2,000 W generator covers it with its running rating alone; add the watts of anything else you run at the same time.

How long a portable power station runs a coffee maker

Runtime of a coffee maker on a portable power station, at 85% inverter efficiency
Battery capacity, Wh	At 1,500 W, h	At 1,200 W, h
500	0.3	0.4
1,000	0.6	0.7
2,000	1.1	1.4
3,600	2	2.6

A 500 Wh portable power station runs a coffee maker drawing 1,500 W for about 0.3 hours at 85% inverter efficiency. Runtime = capacity × 85% ÷ watts; the 85% efficiency is an assumption. The power station's AC output must be at least 1,500 W.

What it costs to run a coffee maker

Running a coffee maker at 1,350 W, the middle of its 1,200–1,500 W range, for one hour a day uses 492.8 kWh a year. That costs about $89 a year at $0.18 per kWh, the US average residential price for August 2026.

$7.39 / month

Per day: $0.24
Per year: $89
Energy per day: 1.35 kWh
Energy per month: 41.1 kWh

How it is calculated

kWh per day = 1,350 W × 1 h ÷ 1,000 = 1.35
Per month = 1.35 kWh × 30.4 days × $0.18 = $7.39

What affects coffee maker power use

The heater that brings water to brewing temperature draws most of the power, and only while it heats. Drip makers keep a warming plate on after brewing, and pod brewers reheat their reservoir unless set to turn off. Auto-off settings cut the standby use.

How the amps are calculated

Amps = watts ÷ volts. For 1,500 W at 120 V that is 12.5 A. The 1,200–1,500 W range covers typical models; the nameplate on a coffee maker gives the exact figure.
