How Battery Charging works:
Batteries get charged when current is passed through them. Higher current and voltages lead to faster charge. Depending on the voltage input.
Power is measured in watts and we calculate watts by multiplying the current by the voltage. The more watts, the more power. The higher the power the quicker the battery can charge. Simple!

Quick Charge vs VOOC Fast Charging
What is Quick Charging:
Quick Charge is a technology found in Qualcomm SoCs, used in devices such as mobile phones, for managing power delivered over USB. Batteries get charged when current is passed through them. Higher current and voltages lead to faster charge. Depending on the voltage input.
The best known fast-charging system is Qualcomm’s Quick Charge, versions 2.0 and 3.0.
What is VOOC Fast Charging
VOOC (Voltage Open Loop Multi-step Constant-Current Charging) flash charging technique developed by OPPO Electronics.
VOOC uses a higher current than normal USB 2.0 charging. VOOC operates at 5V and 4A.
VOOC Fast Charging Versions
VOOC has developed 3 variations:
- VOOC 2.0, which operates at 5V and 4A.
- SuperVOOC a different successor of VOOC 2.0 it operates at 10V/ 5A. It charges a two-cell battery in parallel.
- VOOC 3.0 (2019), which operates at 5V/5A version of VOOC
