There are three form of output: 3.6-6.5V / 3A, 6.5-9V / 2A, 9-12V / 1.5A,it will automatically detects your phone and switch the output form.it using the optimum voltage intelligent negotiation INOV (Intelligent Negotiation for Optimum Voltage) technology, which will be in 200mV incremental steps, and the charging speed, while effectively reducing the thermal energy consumption.
Contrast QC 2.0 fixed voltage approach is directly transferred from the 5V up to 9V, which would be more blunt, now 3.0 to 200mV as a progressive unit. A start charging when the voltage is not high, and later gradually improved, this intelligent upshift method can better optimize charging, because if put up a high voltage reference, in the middle there will be power loss, which will be in the form of heat dissipated.
In addition, it has the ability to backward compatibility, compatible with 2.0, also compatible with other traditions, such as USB charging device, it can also support the iPad or iPhone as before fast charging.
Multiple safety protection, avoid over-current, overload, overheating, short circuit, overcharge and so on.
