Worked as advertised- great backup4/7/2013
Bought one for my wife- one day she realized her cell phone battery needed charging- connected this battery and was able to make her call. The unit is small enough that she told me she left it plugged in her cell phone and placed in her purse to fully charge. Other batteries for this use are much more expensive- it worked so well bought one for myself too. Well worth $20
charging light comes on but never charges. junk. save your money
