For the battery, there is a bag with a strap with which to close the bag. The Power Bank needs about 6 hours to load and keeps in a smartphone with 3000mAh for about 2 charges. There are three terminals, a microUSB input (5V / 1A), a USB A output (5V / 1A) and a USB A output (5V / 2A). I can only recommend all the power bank, who need a small handy battery. Really a super practical part.
