That is correct, this is a mobile charging unit that can be taken with you to charge your items.
A rechargeable battery, like what is in the Veho Pebble Smartstick, can be recharged several hundred times, but like anything, this can't last forever. Sooner or later the battery will no longer be able to hold a charge (maybe you've seen this on an old cell phone, or some other device that has a chargeable battery). So sooner or later the device will no longer work.
This item comes with the following adapters: iPhone/iPod, Sony Ericsson, Nokia pin tip, mini USB, and micro USB. To see if one of these is compatible with your device, I suggest consulting your users manual.
