Pros: 2 ports! and one is 2.1A (very important) This thing can hold a charge for awhile, probably charges my iphone 4s at least 3 times. I do use my phone while it is being charged. Comes with a micro USB cord Ports are labeled so you know which is 2A 7k mAh is accurate and even modest as proved by CNET reviews

Cons: Bulky for its power The case works but also very bulky Takes a LONG time to charge (overnight)

Overall Review: I got this as a slick deal for a total of 17$, there are better alternatives going on sale all the time. I would shop around. Overall very satisfied, but it is bulky.
