Thanks for the correction John, I knew there was something about the power connectors I wasn't remembering. Still, I think that means the longer plug on the cable end of the ADC20 cable will not fit in the shorter V3 socket, but the shorter barrel on the "V3" power cable should fit fine in the socket of the ADC20. Even with a somewhat shorter barrel, that cord will still make good contact internally within the socket. The problem the other way around isn't that you can't get an electrical contact, it's that the longer ADC20 connector on that power cable is too long to allow for the lock-ring to work on the V3. I'd still call Ed.
