So,This Powerbank Is Shaped Like An iPhone 6,So Its Kind Of A Weird And Unique Accesory To Carry Around. The Materials Used For It Are Also Prone To Scratching. However,Its Works Just Fine With Normal Devices. There Is only 1 USB Port For Charging However It Works Just Fine. There Is Also A Micro-USB Port For Charging It. You Can Press the Home Button And It'll Tell You If the Powerbank's Usable Or Not. If Its Red,That Means Theres No Charge left. And If Its Blue,That Means There's Some Charge In The Powerbank And/or Its Ready For Use.
