About How Many Watts
An independent guide to sizing portable power for camping, power cuts and off-grid life.
The site is run by Michael Galvin, based in the UK. Portable power stations are expensive, and the specs are confusing: watts, watt-hours, solar input and boost modes. The goal here is simple. Work out what you actually need, then see which units from several brands can do it.
