The figures below are typical ratings; the label on your own appliance and its real draw can differ. A plug-in energy meter measures one corded 120 V appliance; a whole-home monitor's sensors clip on inside the panel and log every circuit.

How many watts does each appliance use?
How many watts does a refrigerator use?
A typical home refrigerator draws about 100–200 watts while the compressor runs (≈150 W average). Because it cycles on and off, it uses roughly 1–2 kWh per day. Startup surge is much higher, around 800 W for a moment, which matters when sizing a generator. Older or larger units use more.
How many watts does a TV use?
A modern 55-inch LED TV uses about 60–120 watts (≈90 W), or roughly 0.1–0.2 kWh for a few hours of viewing. Larger 4K and OLED sets draw more; older plasma TVs used several times as much.
How many watts does a microwave use?
Most countertop microwaves draw 900–1,200 watts from the outlet while cooking (more than the lower 'cooking power' number on the label). They run only a few minutes at a time, so daily energy use stays small despite the high wattage.
How many watts does an air conditioner use?
A window AC (≈10,000 BTU) uses about 1,000–1,500 watts; a central AC (3 ton) draws roughly 3,000–3,500 watts running, with a much larger startup surge (up to ~8,000 W). Air conditioning is one of the biggest summer electricity users.
How many watts does a space heater use?
A standard electric space heater uses 1,500 watts on high, the maximum for a 120-volt outlet. Run for 6 hours that's about 9 kWh a day, which is why space heaters spike winter bills so quickly.
How many watts does an electric dryer use?
An electric clothes dryer draws about 3,000 watts on its 240-volt circuit, and a typical load uses roughly 3 kWh. Gas dryers use far less electricity because the heat comes from gas, not a heating element.
How many watts does a washing machine use?
A washing machine uses about 500 watts while running, with a brief surge (~1,200 W) when the motor starts. Most of a hot-water wash's energy actually goes to heating the water, not running the machine.
How many watts does a PS5 or game console use?
A game console like a PS5 or Xbox Series X uses about 150–200 watts while gaming and only a few watts in rest mode. A few hours of play is well under 1 kWh.
How many watts does a house use?
An average US home uses about 30 kWh per day, which averages to roughly 1,250 watts of continuous draw, but it swings from a few hundred watts overnight to several thousand when the AC, dryer, oven, or EV charger runs. Estimate yours with our electricity bill calculator.

Values are typical averages: actual wattage is printed on the appliance nameplate. Starting (surge) watts spike for motor-driven appliances and can briefly run several times higher than running watts.
