Quick Charge 3.0 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. Intelligent Charge 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. Full Compatibility Full compatibility and interoperability enables true universal charging. When plugged into a powered device without Quick Charge 3.0 capability,the IC automatically disables the higher-power/higher-power capability to ensure safe operation.Tests confirm that smartphones with high-capacity batteries can be fully charged in as little as one hour.using Quick Charge 3.0 chargers.optimize input current range Enable ture nuiversal charging. Rigorous Safety standard This 3 port charger comply with rigorous standard, like UL/FCC/3C , to keep you and your devices safe.
