This is small in size but packs a punch, charges up phones fast. Is built strong and durable, with nice rounded corners its easy to hold, small enough to fit inside a coat pocket, a backpack or a purse. Has 2 usb ports with power surge protection(ismart technology)that helps it from over charging my phone or tablet. Has a button on top, to check how much power you have left in the power bank. Comes with a nice pouch, instruction booklet, 2 usb cables and warranty card. This would make a nice gift too!
