I doubt if this device works as advertised. Most devices of this nature actually contain a battery that is charged via USB. A standard USB port cannot provide sufficient power to properly charge a camera body.
While the battery can and will begin to charge with most of them, the problem is that the camera consumes power faster than the battery can be charged. The operating battery life is typically shorter than those of a standard Canon rechargeable battery.
