Negative Positive
Title: junk. it does nothing for you
Review: looking at canon's website and seeing this charger available on the accessories matrix, one would assume that it would power the camera. it does, kinda, the power goes into the battery compartment. so you can not chage a battery with this device. it only powers the camera if you are using the usb connector. it is practically useless.
