Power station sizes explained: 300, 500, 1000 and 2000

Updated 11 October 2026

Power stations are named by numbers, and the numbers mean two different things. A "1000" can refer to the battery in watt-hours (Wh) or to the output in watts (W). Mixing them up is the most common buying mistake.

How many units we list in each battery size band. Battery size (Wh) and output (W) are separate numbers, so check both.

A 2000 Wh power station and a 2000 W power station are different things

  • Wh is the size of the battery. A 2,000 Wh unit holds enough energy to run a 100 W load for about 15 hours once you allow for losses.
  • W is how much it can power at once. A 2,000 W unit can run a kettle, but a 2,000 Wh battery behind a 300 W inverter couldn't.

You need enough of both. Watts vs watt-hours explains the difference with examples.

What each size tends to suit

Battery sizeTypically suits
300 to 600 WhPhones, lights, a laptop, a router, a speaker. A weekend of light camping or a short power cut.
about 1,000 WhA weekend with a laptop and lights, or a few hours of TV and a fridge in a power cut. See the camping examples.
about 2,000 WhA fridge running for a couple of days (see fridge runtimes), power tools, or a van or cabin with solar.
3,000 Wh and aboveLonger outages, heavier daily use, and setups that are meant to be expanded.

Units with 2,000 W of output or more

These can run higher-wattage items, such as a kettle or some power tools. Output isn't the same as battery size, so check the capacity column too.
