The listing, USB Powerbank (Micro usb) has ended.
This is a usb Powerbank. It comes with the micro usb wire. you plug the Powerbank up to charge it then when it has charges take it with you. If your portable device gets low or dies all together the Powerbank can recharge it to about 30-50%, Or you can run the small portable device for about 4 hours. This little this is a must have on the go. I have a few of them and I just keep it in the glove box of my car or in my tablet case. As always good luck and good bidding!!
