I think I'll be sticking with my own solution: a Yuasa 6V gel-cell battery in a leatherette hip pack (an old digital camera case), with wiring and a generic power plug I added myself. The plug connects to the USB power adapter for my iPAQ hx4700. I also have a modded cigarette-lighter stepdown circuit, altered to plug inline between the hip pack and whatever else, just in case having less than 6VDC input is an issue. Total cost: a fraction of these.

Yup, I have a Zune tip from Gomadic and it works really well with the Quad Charge unit...but that's not so portable. :wink:
