Details[edit] It 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 which most USB
USB
standards allow for. Numerous other companies have their own competing technologies; these include Mediatek's Pump Express, OPPO's VOOC
VOOC
(licensed to OnePlus
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
USB
Implementers Forum (USB IF) announced that their USB
USB
Power Delivery ( USB
USB
PD) standard had been finalized which allows for devices to transfer up to 100 watts of power over capable USB
USB
ports. From Quick Charge
Quick Charge
v3.0 onwards the driving technology of it has been named as INOV (Intelligent Negotiation for Optimal Voltage) with independent versioning that improves on the quantized levels of allowed charging voltages. Quick Charge
Quick Charge
4 was announced in December 2016 alongside the Snapdragon 835; it will implement additional safety measures to protect against overcharging and overheating, and will be compliant with USB-C
USB-C
and the USB
USB
Power Delivery (USB-PD) specifications.[2] Versions[edit]
