The Xtreme Cables 5200mAh Universal Rapid Battery Charger is what you might call a jack of all trades. In addition to charging standard USB devices, it allows you to charge Apple 30-pin, mini USB, micro USB and Nintendo DS devices using the four included adapters. So with a single charging device you can keep mobile phones, tablets, e-readers and more powered up and ready to go.
The 5200mAh charger simply plugs into the micro USB port on your device to provide up to 600 hours of emergency standby time. When the charger itself becomes a little low on power, you can connect it to a computer or USB adapter to rejuice it. For convenience, an LED indicator shows the capacity of the battery at the touch of a button. Another very handy feature is the built-in LED flashlight, which can illuminate your space in case you get caught in the dark.
