1 out of 5 eggsDoesn't work after 2 uses

Pros: None - it doesn't work

Cons: I've used it twice and now it won't charge any device. The battery indicates that it's fully charged yet won't charge anything, just turns off as soon as I connect it to my phone, my wife's phone or tablet.

5 out of 5 eggsAmazing.

Pros: -High capacity
-Got it for $15 during an awesome Shell Shocker deal
-Charges my phone as fast as a wall charger would
-Small, about the size of my wallet. (Maybe a bit taller)

Cons: -Heavy
-Takes 10-14 hours to charge it (It's a given with any high-capacity charger.)
-I did not buy more than one of these

5 out of 5 eggsso far so good

Pros: Came nearly fully charged (4 LEDs), just had to top it up for about an hour. It has performed 2 full charges of my Samsung Galaxy Note II using the 2 amp port and just went from 3 to 2 LEDs (75% to 50%) of battery left, so I should get 1 or maybe two more charges out of it before having to recharge the unit itself.

If it keeps performing, this was a great buy for $15!

Cons: None so far.
