Tekkeon has announced the myPower FM, an add-on for the company’s myPower rechargeable iPod battery/dock that adds the ability to transmit music to any radio. The myPower FM, which requires no extra software, snaps onto the bottom of the myPower and is also powered by the all-in-one device. It features a one-touch channel tuner to choose from seven FM frequencies (87.7, 87.9, 88.1, 88.3, 88.5, 88.7, 88.9) and will be available in April for $34.95.

The myPower provides 4G iPod and iPod photo users with an extra 32 hours of play time, 3G iPod users with up to 20 additional hours, and iPod mini users with up to 42 (6GB) or 28 (4GB) extra hours. The device also includes a FireWire port, USB 2.0 port, a line out port, and a 5V charging output.
