Two different numbers

Power isn’t the same as battery use

A kettle pulls far more power than a fridge, but a fridge uses far more battery, because it’s on all day.

Power (watts)

How hard something pulls while it’s on. It decides which power station can run it at all. A kettle pulls about 2,000W, so it needs a power station that can give at least that. Things marked High power pull 1,000W or more: use them one at a time.

Battery a day (watt-hours)

Power × how long it’s on. It decides how long a charge lasts. A kettle used for 6 minutes a day takes about 200Wh. A fridge-freezer averaging 45W, all day and night, takes about 1,080Wh: five times as much.

How long it lasts

The last columns show how long one charge lasts with that typical use, on its own. With a few things plugged in, add up the battery a day. Our finder does that for your own list.

Reading the bars

Battery use in a typical day

The same bars appear on our finder, so you can see at a glance what uses the most.

Tinyunder 50 Wh a day

Medium250 Wh to 750 Wh a day
High750 Wh to 1.5 kWh a day
Very high1.5 kWh a day or more

At home

Power cuts and Storm Season

Most used first. Fridges and freezers use the most, because they never switch off for long.

Typical figures for common models. Your own appliance may use more or less: the label or plug usually shows its watts. Fridges, freezers and heaters switch on and off, so we show their average. Starting a pump, compressor or fridge can briefly take two to three times its running power. Usable battery is about 85% of the rated size, after the inverter.
