Wagan 2315 is the first to provide a battery charger & portable USB power supply in the same unit. Unlike any other FM broadcaster plug the 2315 broadcaster into your car's 12V power outlet. Plug your iPod (or any other mp3 player) into the USB port to keep your player charged. Plug your headphone jack into the line-in jack on the broadcaster and select an open FM frequency.
So far, this set-up is like dozens of other 12V FM broadcasters - but here's the difference: pull this FM broadcaster out of the socket and the tunes keep playing! The 2315 Broadcaster has two internal 'AAA' batteries that it keeps charged and these provide power to the broadcaster and your mp3 player when you are away from car power.
The 2315 Broadcaster provides a portable back-up power solution for your USB devices like iPods, MP3 players, handheld GPS, Blackberries & smart phones. When in car, the 2315 Broadcaster charges its internal 'AAA' batteries along with your USB device. Unplug it and take it with you - you've now got almost double your device's native battery power!
iPod users will appreciate the compact design and unlike the iTrip, the 2315 FM Audio Broadcaster has its own power & will not put an extra drain on your iPod's battery.

Idea behind this - good. Get your audio transmitter charged up, keep your iPod/iPhone/MP3Player charged up and listen to it at the same time. Unfortunately transmission is very poor in quality (and no way to improve it, no matter how you you move this thing near radio), and its getting horrible when you traveling through metro area, where FM stations are stacked on each other pretty close. FM station from outside can overpower transmission (or interlace with it) from this gadget.
