Most cars these days have a USB port. But often times, there’s just a single port, and it may make you listen to the music on any connected device via USB and disable Bluetooth calling on phones (I’ve encountered this on several cars). This handy 12VDC adapter solves both of those problems.
Just plug the ChargeIt! dual-output charger into your car’s 12VDC outlet, and you can charge two devices simultaneously, and without connecting them to your car’s media system. It’s got both a 1A and a 2.4A port for charging a phone or a tablet, and even has an attached MFi-certified Lightning cable for juicing up Apple devices without need for an extra cable.
