VOOC flash charge charges quickly.
VOOC flash charge is OPPO independent research and development of fast charging technology, and has 18 patents, obtained a number of authoritative certifications, including the Swiss IEC, the fastest charging speed increased by 4 times, and there is an invulnerable intelligent full-end five-level protection, VOOC flash charge is the world's first mass-produced commercial fast charge scheme, compared with other fast charge schemes. The technical threshold is higher, and the VOOC flash charge requires a customized adapter and battery to be used together. OPPO customized a special adapter, battery, data cable, circuit, interface, and for this in-depth development of intelligent all-end five-level protection technology, security is impeccable.
Dual-engine flash charge is a mobile phone fast charge technology, similar to OPPO's VOOC flash charge technology, but the charging speed is not as fast as VOOC flash charge technology. VOOC flash charge is 4 times faster than the ordinary charging speed, double engine flash charge is 2 times faster than the ordinary speed, according to the actual test, with OPPO R7s charging test, full charge only takes about 70 minutes.
They just call it something different. Are fast charging technology, but the way to achieve is not the same. OPPO VOOC flash charge is a low voltage high current fast charge, low temperature when charging, more safe. QC3.0 is high, low current fast charging, charging temperature is slightly higher, but the wire requirements are low, more convenient.
