Video Review: U2O iUP-5400 Battery

Rating: 9 out of 10
Pros: Comes with tons of adapter tips for many devices. Built-in LED light.
Cons: You can only charge the unit with the wall AC adapter.
Overall: This is a very nice external battery pack that every iPhone owner should have. I’m still shocked that it can fully charge an iPhone at least 3 times. Even though it has some weight to it, it’s still pocketable and easy to carry. For $60, it’s a really good buy.
