Contax RTW Power Pack projector but then againPower your Contax Real Time Winder externally with this power pack. Toss in the AA battery insert from your Real Time Winder and hook your camera up with the included power cord. Why would you do this? Well, if it's cold out, you can stash this holder in a pocket and prolong your battery life. It's quicker to swap battery inserts, too (inserts are not included). In excellent condition, with cable. Belt case not included.
