    the portable battery works well , simulate a power supply turn on during 30 minutes.You can use to any device that use usb to charger
    The size is perfect to use in any where and with any system that use usb to charger.During the charger are there the led to change from red (charger) to green ( charger full)
    I recommend buying this device.I am not sure if has 3000mAh, but it help me every time that I need to use.

    Seems to charge my Nokia N9 just fine. It's hard to say how fast it goes, but I think it's comparable with the charging rate from a normal usb on the pc/laptopLED that tells u when it's charging, and when it's done charging.1 cable for all the work (made for powering devices afaik)
    Not sure if it stops charging when the device is full
    For the price, it's a handy tool when desperate for power
  • Great useful product.

    With the two outputs can easily charge my tablet and my smartphone. Especially if I'm in places that it is sometimes difficult to get a place to charge them or do not have electricity nearby.
    As it has multiple connectors my friends can also charge their electronic devices in an emergency sittuation.It is kind of big and heavy. So it is not very easy to carry. It is still good to have one in your car....just in case!
    Nice handy backup battery for an emergency or daybday sittuation.
  • Good Battery Pack

    -can charge a nook color from 0- 100 and a cell phone and there is still a little juice left too. small and fits in the palm of your hand. -dimensions are 3inches long, 2 wide, and 1 thick-simple to use -price, cheapest external battery over 6000 mah -
    -if it took less time to charge it would be amazing-the charging adapter is for the U.S
    buy it, its the cheapest 8800 mah battery pack I've seen around
