I bought after a long search of this device as a replacement for the original charger that came with my EOS 300D. Reason: LT In my total 4 batteries, 3 of only a few months old, were camera only half filled and broke after a short time a whole, although the charger identifying her as full.. A Google search showed that this could be the fault of the charger thoroughly, so I decided to buy a third-party device. The first test: Two supposedly full BP 511 taken from the Canon charger and inserted into the Hahnel charger; This diagnosed a charge level of 20%. The next morning: When a battery inserted in the camera, where they are now displayed as full. Canon charger properly as electronic waste ...
Positive side effect: The unit also charges the battery of my video camera (HG10), as it offers two different bays. Probably fit the batteries IXUS V3, but I've not yet tested.
Conclusion: For owners of Canon equipment thoroughly recommended.
