Portable Power Station Sizes Explained: What You Actually Need in the UK

Picking the wrong size portable power station is one of the most common mistakes UK buyers make. Too small and you're rationing charge. Too large and you've spent £400 more than you needed to.

Here's how the size bands break down.

Small (200-500Wh) handles phones, tablets, and laptops. Fine for a day trip or a one-night stay with light usage.

Medium (500-1,500Wh) covers weekend camping properly. You can run a 12V car fridge for 24 hours, charge all your devices, and still have capacity left over.

Large (1,500Wh+) is for home backup, full-time van life, or anyone running heaters and water pumps. Don't underspec this. A small heater pulls 500-1,000W per hour.

Solar charging works in the UK, but slower than the marketing suggests. A 200W panel realistically delivers 100-140W here. Plan for 8-10 hours of decent sun to fill a 1,000Wh battery from flat.
