Not busting your bubble, but why not just buy an M10 or something like that, and just stock up on batteries[rechargeable] of course

I've made a few homebrew cables, no need to take the iriver apart.  It's just computer USB -> iRiver charger jack.  I leave my AC charger at home, use this cable to charge at work, in car, etc.

- Find a generic USB cable for computer, cut it in half.  Keep the computer end, toss the camera/printer end.
- Find a cable with the right tip to fit into the iRiver.  Cut that in half, save the tip, toss the rest.

In the USB cable there are 4 wires.  The outer two are 5 volts, generally red/black with red=+ and black =-  The other 2 are data lines, just forget about them.  Carefully connect the 2 cables, solder it together so it's 5V to the tip with + on the inside, - on the outside.  Double and triple check the polarity before you plug it into your iRiver.

Yep. I can't find either of my iriver chargers so I use a USB>iriver jack cable to charge my mp3 player at work.

Tapin...the iRiver I got from you runs on one of these....a trip to teh Shack and a hot Iron is all you need....

Build 5v battery pack

A couple people have had success building ~5v battery packs out of 4 x 1.2v NiMH cells.  Fully charged NiMH cells will put out ~1.4v each, so this pack will deliver around 5.6v fully charged - which is a bit too high for the iriver, outside it's operating voltage specs.  If you run it with a slightly too high voltage, you may lock up the iriver which will require resetting it by pressing the reset button on the bottom with a paper clip or toothpick.  If the voltage is a little high, run the batts for a few minutes on another device (e.g. small light bulb) to drain the battery which will reduce the output voltage enough to fall within the iriver's voltage specs.  There’s a thread about it here: http://www.misticriver.net/showthread.php?t=4937

usually on iriver you can switch charge via usb on or off in the menu. (mine is rockboxed, dunno if its also availiable in stock firmware)

Did ya do the mod Kev?
