I have been using the Delkin ePad for sometime and really like it. Batteries are a bit of a problem, it is a bit difficult to change the battery (specially when its cold). I sent one of my ePads to
Quantum to see if they could design a custom cord to fit the ePad.
The engineers were VERY pleasant to deal with and a cord is being made. Will give an update when I receive it. With a Quantum Turbo 2x2 I will be able to power my 1-Ds, 550 flash and the ePad.
I have no idea how many transfers I will get out of one battery but I don't think you could shoot enough in a day to deplete them.
I am sure the cord will be available to anyone soon. You might give them a call if you need one.
