AmbranePower Bank

Let's face it, the phone dies at the worst of times. A power bank can be godsend at such times. Or when travelling, you don't want to risk random USB ports on the plane or train, carry a power bank and you're sorted for days.

This power bank has a capacity of 10Ah so if your phone has a typical 5Ah battery, it can fully charge it twice. The charging speed is quite good at around 22W.

The Magsafe version can charge wirelessly as well although a bit slowly. It has an attachment to support Qi charge devices too.
