It looks like it has a microUSB port/cable which should be for charging. You can use the same cable in reverse order to charge any devices with microUSB ports.
In for one, my 3000mAh battery for my Samsung GS3 is great, but won't last a whole weekend of camping. 11000 should last me quite a bit longer, even with power-hungry high-end games
