Many years ago I had a handy gadget for my A series Canon cameras that linked a small battery holder carried inside the clothing to the camera outside via a cable for shooting in very low temperatures.
My intention is to make something similar for a Fuji x10 using the CP-50 DC coupler unit.

This is where I need a little bit of technical advice. It's a long time since I learned some basic physics at school.
As far as I can see, the AC-5VX AC power adapter that this is supposed to couple with produces an output of 5 Volts at 1.5 Amps. (I hope I'm not missing anything obvious.)

So, is there any reason that this power could not be provided by a rechargeable USB style power pack along the lines of this one?

If that pack is not suitable, does anyone know something else that would do the job?
