That seems to be the thought behind the latest iPod accessory to come out of the XtremeMac camp, because here is the InCharge FM, a device that will simultaneously top up the battery of your music player and send those tunes out via FM radio.

We’ve seen countless accessories for the Apple portable player in the past and there’s a good chance that this isn’t a novel idea. Even so, XtremeMac has seemingly done a great job of integrating the FM transmitter into what looks like little more than a power cable for your iPod. It’ll take its juice from a standard vehicular 12 volt power outlet (i.e., the cigarette lighter jack). They say that the Quintic PureFM technology provides “near CD quality.” How near remains to be seen.

The XtremeMac InCharge FM will be launching soon with an asking price of $69.95.
