ya that one is a good one, supposedly a aa battery is 3000mah, so 3v is 6000mah, but then you could have to boost 3v up to about 5 so lets just say u boost it to 6 (u wont but it is easy math) so then it would only be 3000mah without internal resistenace and crap like that.

you could get a couple of good recharges though.

and please keep us updated on this, and give us some pics please!

Yes, it will be turning much of the energy into heat and nothing more, but again, its a cheap and emergency charger. On mine I spent about $1, excluding the batteries.

If you use programs like Card Export you battery will die while connected if you dont have it plugged into the wall as well, your best bet is probably just to have it well charged when you leave the house.. or try turning the brightness all the way down, i find that is an awesome way to save hours of power. also dont use the camera a lot (provided you do).. never the less.. try looking at charge packs for gameboys. They might work, although i have no idea at all
