Appliance Wattage Chart: Running Watts, Surge Watts and Wh per Day

Every appliance has three numbers that matter off-grid: what it draws while running, what it spikes to at the instant it starts, and how many watt-hours it eats in a day. This chart carries all three for 294 appliances, plus how long a 5 kWh battery lasts on each alone.

The chart

Click any heading to sort. Ranges are typical for the class; the bold figure drives that row’s arithmetic. In the 120 V view, anything over 1,800 W is shown on the 240 V circuit it would have to be wired to; in the 230 V view, anything over 3,680 W is a fixed connection rather than a plug.

Plate rating label VCE Virginia Cooperative Extension wattage table 2901-9014, 2020 ES ENERGY STAR and EnergyGuide data RECS EIA Residential Energy Consumption Survey 2020, modeled end use LBNL Lawrence Berkeley whole-house standby metering, 2000

How this is calculated

Watt-hours per day is running watts multiplied by hours used per day. The Department of Energy's Energy Saver pages write the same rule as wattage times hours used per day divided by 1,000, giving daily kilowatt-hours.

Worked example. A 55-inch television draws 100 W and runs five hours: 100 × 5 = 500 Wh a day. A 5 kWh battery does not deliver 5,000 Wh to the socket — after inverter losses, call it 4,500 Wh. So 4,500 ÷ 500 = 9 days on the television alone.

The surge column is running watts times a start-up factor: 1 for heating elements, 3 for compressors and induction motors, which briefly pull three times their running current while the rotor spins up. Current draw is watts divided by supply voltage, so the same appliance shows fewer amps at 230 V.

The reality check. Plate watts times hours is an estimate, and cycling appliances run past it. The EIA's 2020 Residential Energy Consumption Survey puts the average most-used US refrigerator at 617 kWh a year, about 1,690 Wh a day — above what 150 W over nine hours predicts, because the national stock includes older and larger boxes.

EIA table CE5.3b, released June 2023 and revised March 2024: 2.106 million Btu per household. RECS end uses are modeled from billing data and household characteristics, not measured appliance by appliance.

Quick answers

How many watts does a refrigerator use?

Roughly 90–250 W while the compressor runs, near 150 W typically. Because it cycles, daily energy lands around 1,200–1,700 Wh.

What are surge watts and why do they matter?

The spike at the instant of starting: about 3× running watts on anything with an induction motor, nothing on a kettle. Surge decides whether the inverter can start it.

How do I work out watt-hours per day?

Running watts × hours per day. A 100 W television for five hours is 500 Wh.

How long will a 5 kWh battery run my appliances?

Take 4,500 Wh of usable output after inverter losses and divide by the appliance's Wh per day. A 150 W refrigerator running nine hours covers just over three days.

Why does the same appliance use different watts in Europe?

Circuit limits differ, and so do the products built for them: a 120 V, 15 A US circuit stops at 1,800 W, a 230 V, 16 A European circuit allows 3,680 W.

How much standby power does a house use?

Lawrence Berkeley metered ten California homes for LBNL-45967 (Ross and Meier, 2000) and found 14–169 W of permanent draw, averaging 67 W. Standby rules have tightened since, so a comparable house today should land under that average.

Reading a rating plate

The label is on the back, the base, or inside the door. Sometimes it gives watts. Often it gives volts and amps, and you multiply: 120 V × 12.5 A = 1,500 W.

Two traps live there. Motor plates quote full-load amps, which says nothing about inrush. And a heating plate is a maximum: a thermostat cycling at 40 percent turns 1,500 plate watts into 600 average.

A plug-in energy monitor settles both traps. Leave it on the appliance for a day, then feed the measured watt-hours into the off-grid load calculator.

Why the same appliance reads differently on each side of the Atlantic

A 15 A, 120 V circuit carries 1,800 W. The National Electrical Code, article 210.20(A), sizes the breaker at 125 percent of any continuous load, meaning anything drawing for three hours or more, which holds that circuit to 1,440 W in practice.

That ceiling shaped the American catalog: kettles stop at 1,500 W, hair dryers at 1,875 W, portable heaters at 1,500 W. Anything larger moves to a 240 V split-phase circuit, and off-grid that means a split-phase inverter.

A continental socket circuit runs 230 V at 16 A, allowing 3,680 W from one outlet, so kettles and heaters are built bigger rather than moved to a second voltage. British sockets are the tighter case: the 13 A fuse in a BS 1363 plug caps a single appliance near 2,990 W, which is why British kettles stop around 3,000 W.

Ecodesign rules push the other way elsewhere. Regulation (EU) 666/2013 has capped corded vacuum cleaners at 900 W since 1 September 2017, down from the 1,600 W limit that applied from 1 September 2014.

The voltage selector recalculates the current column and swaps in the European figure wherever a class is built differently: kettles, dryers, water heaters, vacuums, cooktops and heaters.

Surge watts: the number that trips inverters

An induction motor at rest looks almost like a short circuit. For a fraction of a second the current runs several times higher than normal, and every compressor, pump and air conditioner does it on every start.

450 W 150 W 0 W start-up surge, under a second running watts, hours at a time time

A 150 W refrigerator compressor asks its inverter for 450 W on start-up.

An inverter must clear the largest single surge on top of whatever is already running, so a 2,000 W inverter and a 1,000 W well pump are not a match even though the pump uses 400 Wh a day. A soft-start kit is the cheap way out. Micro-Air specifies its EasyStart at a 65 to 75 percent cut in starting current against the compressor's locked-rotor amps, which brings most household surges inside a modest inverter.

Resistive loads have the opposite shape: a 1,500 W kettle draws 1,500 W from the first instant and never more.

The load nobody adds up

The bottom section of the chart is equipment that never turns off. The figures look trivial, 3 W here and 8 W there, and they run all 8,760 hours a year.

Lawrence Berkeley metered ten California homes for LBNL-45967 (Ross and Meier, 2000) and put the whole-house total between 14 W and 169 W, averaging 67 W — roughly 1,600 Wh a day spent on nothing.

Those readings were taken in 2000, before the per-device standby limits, so a comparable house today should land lower. The limits themselves differ by market.

The US route was purchasing rather than a ban. Executive Order 13221, signed 31 July 2001, requires federal agencies to buy off-the-shelf products drawing one watt or less in standby, and ENERGY STAR criteria carry standby limits product by product. Nothing stops a manufacturer selling a thirstier model to a household.

Europe legislated the device. Regulation (EC) 1275/2008 capped off mode at 1.00 W, then 0.50 W four years on, with standby allowed 1.00 W where the product shows a display. Networked standby has its own ladder, down to 2.00 W for most equipment since 1 January 2019.

Your own inverter belongs on the list. Victron's MultiPlus-II datasheet rates the 48/5000 at 18 W with nothing connected and the 48/15000 at 55 W. Search mode takes the 48/5000 down to 2 W, at the cost of a pause before it wakes for a load.

Where this chart stops

Ranges are typical for the class rather than a specification for your unit. Age, ambient temperature and duty cycle move a real appliance off the middle figure: a refrigerator in a 95°F (35°C) garage runs far longer than the same box in a cool kitchen.

Treat anything thermostatic as a daily watt-hour figure, size anything with a motor on its surge, and the rest is multiplication.

Tick your numbers off in the can I run my house off-grid calculator, which turns a load list into daily kWh, peak load, surge watts and a ballpark array and battery size. The load audit worksheet is the room-by-room long-hand version, what size power station do I need maps totals onto equipment, and inverter sizing covers motor starts. The tools hub has the rest.

EcoFlow

DELTA Pro 3, DELTA 3, River 3 & extra batteries

The densest hardware in the class: 4kWh and 4,000W with real 120/240V split-phase from one box, the fastest AC recharge here, and the highest expansion ceiling of any portable station.

Bluetti

AC200L, AC300/AC500 heads, Apex 300 & B300K packs

The only modular topology on this page: AC300 and AC500 are battery-less heads, so a dead inverter does not strand your batteries and a dead pack does not strand the inverter. Cheapest expansion per kWh, and lifting mode carries motor surge.

Jackery

Explorer 2000 v2 / 3000 v2 & SolarSaga panels

Genuinely the lightest 2kWh unit you can buy — about 37 lb, roughly 18 lb per kWh, half the carrying weight of the big split-phase boxes. The 2000 v2 finally takes XT60 solar input, so any third-party panel works.
