Oppo VOOC (Voltage Open Loop Multi-step Constant-Current Charging), also known as a Warp Charge or SUPERVOOC on OnePlus devices and Dart Charge on Realme devices, is a proprietary rapid-charge technology created by BBK Electronics. In contrast to the USB Power Delivery and Qualcomm Quick Charge technology, which increases the voltage during fast charging, VOOC uses a higher current than standard USB charging. 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, OPPO claims, improves the speed and safety of the charge.VOOC 2.0 has been licensed to OnePlus as Dash Charge technology. A single-cell, 30-watt (5 V/6 A) version of VOOC 4.0 has also been licensed to OnePlus as Warp Charge. OnePlus does not market its phones as VOOC-compatible despite the fact that VOOC 2.0 and Dash are compatible with the phones.As of July 2019, VOOC has been licensed to 14 other corporations, most of which are in the phone charging and power strip industries. Oppo claims that more than 1000 patents around VOOC have been filed worldwide.
