I have an Iriver H10 (20 gig with the integrated battery). Do any of you bring along an mp3 player that dosen't take standard AA or AAA batteries. Do you have any methods to power them? I know theres an Ipod specific AA battery charger, but that won't quite work for me. I could probably rig up something with a generator, but I'm shying away from that for weight, complexity and price reasons.
I haven't been able to think of anything and figure I'll probably just end up taking a portable radio with me, but I figured I'd ask here anyway.
