Which power station is right for me?
Five quick questions. You get the capacity (Wh) and output (W) you need, and the models from our price-checked quick picks that meet them. The math is shown.
How the selector decides
- Capacity needed (Wh) = average watts × hours ÷ 0.85. The 85% is an assumption for inverter and conversion losses, the same one our runtime calculator uses. It is not a measured figure for any model.
- Output needed (W) is the top of the range you picked in question 2. A model only matches if the brand lists a rated AC output at least that high.
- Budget uses the price on the brand's own site when we checked, which changes often.

Frequently asked questions
What size power station do I need?
Multiply the average watts you will draw by the hours you need, then divide by about 0.85 to allow for conversion losses. For example, 100 W for 12 hours is 1,200 Wh ÷ 0.85, or about 1,412 Wh of rated capacity.
What matters more, Wh or W?
Both. Watt-hours (Wh) set how long it lasts. Watts (W) set how much it can run at the same time. A big battery with a small inverter still cannot run a high-wattage device.
Did you test these models?
No. We have not tested these products. The selector uses brand-listed capacity and output figures and a stated efficiency assumption.
