I have been reading some posts regarding external power and not being very clued in the tech side of things. I was wondering if anybody had tried the tekkeon power all mp3400. Does anybody know if this item would work and if it did how long would it power an 80gig FS4? Thanks for any help.

12V DC should power your FireStore OK...it needs about 7.5W. However, you will need 15V if you want to power the unit and charge the internal battery.
