I'd like to see this, too. Last summer on several occasions I ran through a set of batteries a day for my digital camera. For the 7 and 8-day outings I'm planning this coming summer, that's a lot of batteries! I'm not so worried about my headlamp (my only other battery-powered gizmo at the moment) because it seems to run forever on a set--one spare set is more than enough. But if I could recharge the AA's for the camera, it would save me some weight for longer trips.
