12v DC voltage adapter cable with 40D ? anyone using one of these adaptor cables ?

Fpund this http://www.firstlightoptics.com/prod...omiser300power

Looks pretty handy if it provides the correct polarity and regulation on the voltage and current at the right DC levels for the 40D , not many dark sites or parks have mains access so the Canon 220VAC convertor kit for the 40D is - well - next to useless for astro imaging.

Anyone splashed out and bought one of these ?

I bought the Canon External Power pack for my 40D. It supplies 7.8v to the camera. I chopped the lead to the camera in two and fitted plug/socket combo to the ends. Reconnecting them gives me the original power from the mains but a 7.8v battery can be connected when in the field. LiPo or A123 cells work great but each have their own charging problems. 12V gelcel with 4x diodes in series also will work.
