The Cube invites Canon battery fully. The camera is the battery will also be charged with 100% of. During charging the camera battery a loading progress in percent is displayed. In AA batteries only an animation on the display is running.
The USB port also charges an iPad.
The charging camera batteries and AA batteries will not happen in parallel since the adapter is placed on top, thereby hiding the manholes of photo batteries. The AA adapter is incidentally held magnetically. As a big disadvantage I feel that only 4 AA batteries can be charged as a set. Singly or at least two batteries can not be charged. Who needs only two for a small (additional) flash or a GPS device, is there something helpless!
Although the edges of the metal case have no burrs, would rounded (broken) but something like it better. Otherwise, the processing makes but a high-quality and durable, but unfortunately also some weighty impression. Plugging the Camera Batteries goes smoothly and without play. A Velcro tape for holding of the wound cable would also be desirable, as well as a small desiccant bag for the connector adapter.
Conclusion: at home chic and high quality, traveling good and versatile but also with a need for improvement and something too heavy.
