Digital cameras are power hogs! In some cameras a set of alkaline batteries will power the camera for only 30 minutes before they need to be replaced with a new set. Instead of throwing away a set of AA's when they can no longer provide the power your camera needs (and further clogging our landfills with leaking toxic alkalines), simply recharge the ProPower Pack with the supplied recharger as many as 1,000 times. And the ProPower Pack has no "memory" so, unlike rechargeable NiCad batteries, you can recharge it anytime it's convenient, whether it still has stored power or not.
