CH-910 Dual Battery Carger
The CH-910 holds two battery packs and can charge them one after the other. Once the batteries are charged, the CH-910, with batteries in place, can be clipped to your belt and then connected directly to a Canon Digital Camcorder. This will give you twice the recording time of just one battery. It can be used with any combination of Canon BP-900 series Lithium-Ion batteries
