    Comments about Just Mobile Gum Pro Battery Pack (Black):

    I use this to get a quick charge on my iphone as I am a heavy 3G internet user. I could go from ~15% to 90% in 40 min or so. I could do this 3-4 times before it showed that the battery was low. It's small. powerful. easy to use. Total win

    the only problem with it is that it doesnt come with a wall charger. It expects you to have a USB connection. But, I had an old charger for an android phone that had the same volt/amps and it was miniUSB so it worked perfectly.
