Always handy to know there are items like this about for times of need, I rely on my phone so much as spend a lot of time away and don't always have access to a plug point! This power bank is compact. It charges my phone reasonably quickly but best of all it's slim enough to carry in a pocket to keep the phone topped up. When full it will charge my phone and have a couple of bars left for a top up before it needs to be recharged
