5 out of 5 eggsI love this thing!

Pros: Charges my phone and has enough juice for 2-3 full chargings before it needs to be recharged itself. Love the bluelight indicators that tell you how charged up the unit is. Comes with many switchable connections for various phones.

Cons: A bit heavy and clunky, but not a huge deal. Also, micro usb plug is beginning to bend with heavy use

Other Thoughts: The battery was going out on my Droid X so I got this to keep my phone afloat until I got a new one. Allows me to go on hikes and keep my phone alive until I can charge it again!
