Besides functioning as an FM transmitter, the Monster iCarPlay Wireless 250 also works as a USB charger. The USB cord detaches from the Cigarette Lighter Adapter and can be used as a transmitter around any FM radio/device. Plus the USB cable can be used as a charger via any USB 2.0 enabled port or with a Monster iSlimCharger or iCharger Travel USB wall charger.
