The Mophie Powerstation Hub is a socket charger and a power bank in one. Plug the charger into the socket and use one of the 3 USB ports to charge your smartphone, tablet, or any other device. Are you going out? If so, take the charger with you: you have a fully charged power bank of 6,000mAh at your disposal, which is enough to charge your smartphone 1 or 2 times. The Mophie Powerstation power bank supports both Power Delivery and Quick Charge, so you can charge both iPhones and Android phones extra fast. Moreover, there is also an integrated wireless charger present that you can use if you don't have a cable with you. Did you arrive home with an empty smartphone battery and an empty power bank?
