Quick Charge is a technology found in Qualcomm SoCs, used in devices such as mobiles, for managing power delivered over USB. It offers more power and thus charges batteries in devices faster than standard USB rates allow.

Details[edit]

Quick Charge is a proprietary technology which allows for the charging of battery powered devices, primarily mobile phones, at levels above and beyond the typical 5 volts and 2 amps for which most USB standards allow. Numerous other companies have their own competing technologies; these include Mediatek's Pump Express, OPPO's VOOC (licensed to OnePlus as Dash Charge), and Motorola's TurboPower.[1] To take advantage of Qualcomm Quick Charge, both the host providing power and the device must support it. In 2012 the USB Implementers Forum (USB IF) announced that their USB Power Delivery (USB PD) standard had been finalized which allows for devices to transfer up to 100 watts of power over capable USB ports.

Beginning with version 3, the driving technology behind Quick Charge was named INOV (Intelligent Negotiation for Optimal Voltage), with ensuing versions successively improving upon allowed charging voltage levels.

Quick Charge version 4 was announced in December 2016 alongside the Snapdragon 835. Version 4 implements additional safety measures to protect against overcharging and overheating, and is compliant with both USB⁠-⁠C and USB Power Delivery (USB-PD) specifications.[2]
