More juice on the go

The external battery is doing so far without problems, what to do a mobile phone on the road to power. He is of course a bit thicker than a phone but fits comfortably in your hand and can easily be stowed away by the well rounded shape in a jacket pocket. The included cable and various plug adapters are white (matter of taste). There are two cable lengths, I use only the short, about a hand span long cable.
The PowerPack invites me with a 1800 mAh almost 4 times on, while the phone is in standby while consuming energy.
