The Canon genuine 5DmkII's batteries are rated as 7.2V, but the genuine AC adapter output is rated around 8.1V - seems like the camera is somewhat flexible with voltages?
Hopefully, Jaycar's 12V -> 7.5V adapter will work well with a DC coupler.

Hi Dave
I bought a Jaycar DC-DC converter and did use the "dummy" DR-E6 battery blank from Canon (you can of course use the eBay ones) and wired it up together with a 2-way plug-and-socket fitting - I also used 2 x 1N4001 diodes inline on the positive lead (to drop the voltage down from 9.5V, though the unit is supposed to be 9V on that setting - thus giving me a regulated DC supply of roughly 8.4V DC due to the voltage drop charateristic of diodes of 0.6V for each) - my understanding from the techie at the authorised Canon service center here in Perth is that it is not good to go over the 8.5V DC range for the cameras
Now I use this unit for both my 5D MkII, modded 40D & new 60Da - very happy with it all
HTH
Cheers
Bill
