I had received to review U5 5300mAh portable charger with BostonCell. The package included one U5 5300mAh portable charger with BostonCell and a USB cable. It's a small, lightweight, portable charger that can easily fit in your jeans pocket, jacket, purse, etc. The USB cable is sturdy and fits in my devices very well. What I like about this portable charger unlike the others I have is that it doesn't overheat while charging. It's great to take anywhere to keep your devices up and running while on the go!
