Does anyone know of any travel chargers for the Tungsten line that are powered by AA batteries? I have found one that has its own built in bttery pack which it uses, but you have to charge that first. I want one I can use with AA as I will be traveling soon a bunch to Korea and Japan and sitting in airplanes a lot where I can't recharge things with an outlet and would like to be able to use AAs as they are available everywhere...

Thanks
