What I am really looking for is something called a battery box that hold 4 AA batteries and is used as an emergency charger for a mobile or PDA. I found one at Paden.com that serves this purpose for units that charge through the USB port. The idea is that you insert 4 AA batteries and the device to be charged sucks juice out of the batteries and charges the internal battery. This would come in handy if you were off the grid on a canoe or hiking trip.

The link for it is

Has anyone heard of anything like this with a 2mm plug?

I bought a 4 battery emergency charger for my Archos PMA430 (together with a lot of other stuff for my Archos) from here:

It never worked properly with my 770 (charged only to about 80%), but charges my N800 effortlessly, if a little slower than from an AC outlet. The tip is the "old style" big Nokia tip, but I have a connector with the small, new Nokia tip. I get around two recharges (not from completely zero!) with decent (2.5A) rechargeable AA batteries, or I can keep it plugged in and more than double the N800's battery life (especially nice if I want to play some Internet radio and snooze off).

It's not cheap, but until now it remains the only emergency charger that will charge my N800; none of the cheap, gas station models (they usually take AAA batteries) works. I guess it's got something to do with the charging circuitry in the N800.
