Maximum safe voltage to run a Canon EOS 400D?
Hi folks,
I found this thread when searching for info on the maximum voltage on which it's safe to run a Canon EOS 400D...
I've hooked up the 'fake' battery from a (non-functioning) AC-DC adapter to a 12V - 12V DC adapter (cigarette lighter plug into jump-starter battery pack on one end to standard DC plug/socket on the other). The DC-DC adapter I have supports (among others) 7.5V and 9V. If I run the 400D on 7.5V I get a low-battery warning and no function. If I run it briefly to test on 9V everything works perfectly - but I'm concerned about damaging the camera if I use it for prolonged exposures/cycles (e.g. 4 - 6hrs of 25s exposures with 2s between each exposure for startrails, etc.).
Does anyone have any solid data on what the maximum safe voltage is?
Many thanks,
Jessica
