CALLY is a 2-in-1 device that combines the ability to make phone calls with a wireless headset and the functionality of a traditional car charger. The Bluetooth headset is constantly ready for use with the docking station. The set is extremely comfortable to use, because you only need to pull the headset out of the docking station during an incoming call and the call will be automatically answered. The charger allows you to quickly power two mobile devices at the same time via USB ports. Parameters: input power 12V, output power 5V/2.1A + 2.1A.
