Do you have a device that is suitable for Qualcomm Quick Charge 2.0? Then you're lucky, because you can charge your device up to 75% faster than with a standard charger. This means that in about 30 minutes you can charge 60% when charging (depending on your device). Does your device not have Quick Charge 2.0? Then this charger will, depending on the type, adjust the power to the standard max, for a tablet eg 2.4A and for a smartphone 1A or 2A. He automatically adjusts the required output level depending on your device! The two QC 2.0 ports can also be used simultaneously! This way you can charge 2 QC2.0 devices super fast. The total power of the charger is 36 Watt, which means that 2 ports of 1.5A on 12V (QC2.0) can both deliver 18W.
