Keyspan and Zip-Linq sell the same devices, all produced in Taiwan.

They're doing some very interesting things, leveraging USB charger
standards.

Note this universal charger: http://www.ziplinq.com/pwr.html [1] with
a USB connector. If one bought the USB accessory cable for an iPod, I
wonder if one could charge with this. Note it emulates a USB power
supply, the only "standard" low voltage power source. I also travel
with a cell phone and a Tungsten T. Keyspan/Zip-Linq sell USB cables
that work with this charger.

So, one could travel with a single charger, a set of Zip-Linq cables,
and charge a PDA, Cellphone, and iPod (though not all at once, maybe
rotating them one night at a time ... a bit tricky but I think I could
do it ...).

Anyone want to try it out and report back?

Come to think of it, another way to so something similar might be to
buy a compact powered USB hub. That would also have only one charger,
but it could have 3-4 USB connectors. Or combine a passive USB hub
with this device to charge multiple things at the same time.
Interesting ...
