The Tzumi HyperCharge Car Charger is a dual port car charger supporting up to 18W through Qualcomm Quick Charge 3.0 technology and 15W over USB Type-C. This level of charging should be sufficient to quickly charge your phones and tablets through the DC power outlet of your car.
The car charger has one orange USB Type-A port which supports Qualcomm Quick Charge 3.0 and the following power profiles: 3.6-6.5 volts @ 3 amps, 6.5-9 volts @ 2 amps, 9-12 volts @ 1.5 amps. These power profiles are almost similar as what you also find on the AUKEY CC-T7 Car Charger.
The other USB Type-C port provides 15 watts (5 volts @ 3 amps) standard charging for your USB Type-C devices.
