Link: SynCh Universal Sync Charger for cellphones, iPods, Treos, BlackBerrys, headsets, USB and more. The kwiksynch dual charger is basically a two node USB cable, that permits doubling of a USB port for charging or connecting two USB peripherals to one USB port. I carry a tiny portable 4 port USB hub, but this inexpensive ($14.95) little cable is a a handy computer bag accessory, if you have more than one USB device that needs charging, and you only have 1 or 2 USB ports available. There are car charging cables and tips available from the same company.
