The Thumbdrive Car FM Stereo Transmitter. Plug in a standard USB flash memory drive. Then power up the unit via your car’s cigarette lighter socket. Play MP3 music ‘till you get arrested. $36.95.
Unlike other FM transmitters, it plugs straight into the car’s cigarette lighter/DC power outlet so no device power is used. The USB port even doubles as a charger for any USB device such as the iPod. Ipod and itrip (the leading ipod FM transmitter) users will agree that the itrip sucks ipod power rapidly. This device will charge your ipod (using an ipod USB cable) while transmitting an FM signal.
