    Default 9900 and Powerrocks Magicstick (backup batterty)

    I recently purchased a Magicstick backup battery, however upon trying it on two different 9900s the phone says that it can not charge from the source. The battery does work on my 9700 and other devices that charge by usb. Does anyone else have experience with these batteries or know why its not working on the 9900?

    try a more powerful outlet
    I possess a device, in my pocket, that is capable of accessing the entirety of information known to man.
    I use it to look at pictures of cats and get in arguments with strangers.

    Check to make sure the voltage is high enough to charge the 9900.. I have one for my pb and 9790 and haven't had any probs charging them.. If not, it could be a software issue.

    Most likely it is the insufficient voltage. I always get this message while trying to charge with my car charger that is not from BB.

    Thanks for the replies. Looking at the Magicstick instructions, it says only a device that requires 700mA or less can be charged (although it's advertise with 1A output). The OE charger for the 9900 supplies 750mA, so I guess that is where the problem is.
