How we test performance

How long does the power bank take to charge? How quickly will it charge your devices? And does it deliver on the amount of power that the manufacturer says it will?

Ease of use

Overall
Portability
Capacity and charging indicators
Sockets

How we test ease of use

Are the sockets well marked and far enough apart? Does the capacity indicator work properly? And how easy is it to carry around? We weight these results so that portability is more important in small power banks, and less important in large power banks
