Size your backup
Add up the watts you must keep running, then multiply by the hours you need them.
-
Read the spec sheet
Watt-hours tell you how long a station lasts; watts tell you what it can run. Check both before you buy.
-
Verify the specs
Every review links the manufacturer’s spec sheet. Check those before you buy.
Common questions
- How do you rate portable power stations?
- We compare published manufacturer specs — capacity in watt-hours, continuous and surge output in watts, and recharge times — plus owner feedback and real outage math. Ratings are a starting point for sizing backup power for your home, not a sales pitch.

- UTrendCo is an independent review site for portable power stations and home backup power. We compare EcoFlow, Jackery, Bluetti, Anker and more on capacity, output, and recharge speed — in plain English.
- How do I size backup power for my home?
- Add up the watts of the devices you must keep running, then multiply by the hours you need them — that gives you the watt-hours to shop for. Our buying guides walk through the outage math in plain English.
- Where do your specs come from?
- Every figure we publish comes from the manufacturer’s published data sheet, cross-checked against owner feedback. We show capacity, output and recharge times in plain English so you can compare models apples to apples.
