Verdict An excellent medium-sized power bank
This portable charger is about the size of a glasses case, so you can easily fit it into a tight space.
During testing, we found it has enough capacity to take your phone from flat to full battery twice, with some extra charge to spare. Plus, the power bank itself charges remarkably fast – you won’t be out of juice for too long.
If you're looking for a portable charger that does its job brilliantly, we suggest you stop shopping around, save yourself some time and grab this Best Buy.
