I'm sure it's fine - but not for my needs... 4 by .. S. Dorsey (San Francisco Bay Area)
I purchased the CD-E6 so that I could plug in my 5D MkII using the old AC-E2 box that I owned for my old 5D Mk I. I did this because the full replacement is around $180 (for a power brick? Really Canon? REALLY?!?!) and I already had the 5D AC-E2, so I didn't need to purchase the whole thing.

The adapter plug that goes from the battery pod to the "brick" part of the adapter (from the old 5D adapter) is not the same on the new plug. So now, not only am I out $40 for the plug I purchased, but I'll be out another $180 if I want to purchase the ACK-E6AC adapter that will actually work with the camera.

I got scroooood.

So the REAL question is, now that I own the DR-E6, do the 5D and the 5D MkII use the same voltage? 7.8vdc 2.0A? If so, then I can just splice the 2 wires together from the old and new battery converters. I'm not cutting anything until I know for sure, but be warned that if you are an original 5D owner and you have the AC-E2 adapter, this is in NO WAY compatible with it.

One more thing - the materials on this version, when compared with the AC-E2, are much cheaper. The wires are thinner and flimsier, and the plastic is "cheaper". (I"m not sure how else to describe the plastic)

I agree with you S. Dorsey. For the money you spend on the EOS 5D Mark II with EF 24-105IS, you should get the basic AC Power cord with purchase. And you are are correct, when you order their DC Coupler DR-E6, you are still leveraging the battery charger that comes with the camera. (That's deceptive and cheap if you ask me.)
