Compact Portable Charger, Oripow Spark A3 9600mAh External Battery, Power Bank with Two USB Outputs, Portable Charger for iPhone, iPad, Samsung, HTC, Nexus, LG, Battery Pack for More Phones, Tablets and 5V Digital Devices (Black)

I got this for a trip from January through March in Asia, and I ended up using it daily. This was my experience:What I like:1- VERY compact and portable. It is about 3 1/2 inches tall by just over 2" wide, and less than 1" thick, and it weighs about 6 1/2 ounces, so it is also very light. It is like a tiny pack of smokes - you can even fit it in a shirt pocket if you're caught in a bind.2- 9600mAh means you can charge your phone full about three times from 0%, or up to two times for a tablet.3- I got the blue one, which looks GREAT! It is sleek and stylish, I really like the look.4- It charges quickly. There are 2 ports, one for charging phones, the other for tablets. If you want to charge your phone quicker, use the tablet port.What I didn't like: At this time, a portable charger with this capacity should cost no more than $20.
