The Suitable VOOC (Voltage Open Loop Multi-step Constant-Current Charging Flash Charging system is a proprietary rapid-charge technology , which, at present, is able to charge certain devices from 0 to 75% in just 30 minutes In contrast to USB-IF's USB Power Delivery technology which increases the voltage during fast charging, VOOC uses a higher current than normal USB 2.0 charging Thus, VOOC operates at 5 V and 4 A. The VOOC Flash Charge circuit technology reportedly lowers the temperature of the charging adapter, and creates an interface from the adapter to the phone, which improves the speed and safety of the charge.
