Product Details

What is the Quick Charger 3.0? 

Quick Charge 3.0 is engineered to refuel devices up to four times faster than conventional charging. It is 

designed to charge twice as fast as Quick Charge 1.0 and to be 38 percent more efficient than Quick 

Charge 2.0. Now consumers can spend even less time charging, and can grab and go more quickly.

How does it work? 

Quick Charge 3.0 employs Intelligent Negotiation for Optimum Voltage (INOV), an algorithm which 

allows your portable device to determine what power level to request at any point in time, enabling 

optimum power transfer while maximizing efficiency. It also supports wider voltage options, allowing a 

mobile device to dynamically adjust to the ideal voltage level supported by that specific device. 

Specifically, Quick Charge 3.0 offers a more granular range of voltages: 200mV increments, from 3.6V to 

20V. That way your phone can target one of dozens of power levels.
