This review is from: Logisys Blue 4400 mAh Portable Charger CG4400BL
Bought as Christmas gift, but I tested first. Made sure it was fully charged, let it set a couple weeks, then charged my S-II 3 times from 35% to 50% discharge state. brought the phone to 100% and shutdown twice, on third charge it didn't do complete charge.
As an emergency source, it looks pretty good, but you must understand, it has to be charged also.
