This useful power bank can charge most phones from 0 – 100% around 3 - 4 times (depending on the battery capacity of the phone) before needing to be recharged itself.  If your phone has wireless charging capability, you can attach it to this power bank by using the suction pads. This will enable you to charge your phone while still using it, and without a cable getting in your way. The two USB ports enable you to charge more than one device at the same time.
