OPPO Employs GaN MOSFETs in Three New Flash Charge TechnologiesSeptember 19, 2019 by Paul Shepard
OPPO has announced the launch of three new flash charge technologies: 65W SuperVOOC Fast Charge 2.0, 30W Wireless VOOC Flash Charge and VOOC Flash Charge 4.0, reinforcing its leading position in the fast charging space as the mobile industry enters the 5G era.
The SuperVOOC 2.0, which will be debuted in OPPO's forthcoming Reno Ace smartphone, is the world's most advanced production charging solution, with the ability to fully charge a 4000mAh battery in just 30 minutes.
The 30W Wireless VOOC is one of the best wireless charging technologies on the market, enabling wireless VOOC, for the first time, to be on par with wired VOOC in terms of charging speed.

VOOC 4.0, which has undergone a full upgrade and will be featured in the OPPO K5, is positioned to be the next-generation Flash Charge solution for all.
Zhang Jialiang, head of OPPO's flash charge team said: "VOOC Flash Charge technology has reshaped the way people view charging and allowed OPPO to bring the ultimate charging experience to more than 145 million users worldwide to date. In the future, OPPO will continue upgrading VOOC, SuperVOOC and Wireless VOOC to meet user needs in various scenarios."
65W SuperVOOC: OPPO's most cutting-edge charging technology to date
The industry-leading 65W SuperVOOC 2.0 is taking charging efficiency to new heights through customization and optimization in hardware, software and algorithms. The 65W SuperVOOC 2.0 technology can charge a 4000mAh battery from 1% to 100% in just 27 minutes, and battery fully filled in 30 minutes (battery is not fully filled when the charging indicator hits 100%). The solution can also charge up to 27% in a mere five minutes. It is also backward compatible with SuperVOOC and VOOC Flash Charge.
Building on previous super Flash Charge technology, 65W SuperVOOC 2.0 adopted customized and advanced components, design, and manufacturing process to improve charging efficiency while suppressing heat generation, delivering a superb charging experience. OPPO SuperVOOC 2.0 also adopted the Gallium Nitride (GaN) semiconductors, which effectively shortens charging time and further reduces adapter size.
The SuperVOOC 2.0 not only delivers improved charging performance, but also enhanced safety. OPPO has placed five safety protection measures throughout the adapter, wire and handset ends to ensure maximum safety during charging.
30W Wireless VOOC Flash Charge delivers performance as fast as wired solutions
OPPO's 30W Wireless VOOC Flash Charge technology is designed to meet the needs of the increasingly diversified and fragmented nature of users' charging scenarios.
Using one of the best wireless charging technologies on the market, the 30W Wireless VOOC Flash Charge allows a 4000mAh battery to reach a full charge within 80 minutes. Compatible with the QI standard, it also supports a charging power of 5W or 10W, delivering a charging experience on par with that of wired VOOC Flash Charge.
The 30W Wireless VOOC Flash Charge uses real-time adjustment of the charging process and efficient charging components to ensure a more efficient and safer charging while avoiding overheating.
To enhance safety, OPPO has adopted several hardware designs to avoid overheating, HVDC and a foreign object detection function that ensures charging stops immediately when the charging board detects the intrusion of foreign metal objects.
30W VOOC 4.0: The next generation Flash Charge solution for all
In addition to the 65W SuperVOOC 2.0 and 30W Wireless VOOC Flash Charge, OPPO has upgraded VOOC Flash Charge to Version 4.0. Featuring a charging experience with end-to-end optimization, VOOC 4.0 is set to become the next generation Flash Charge solution for all.
Thanks to larger charging power comparing with VOOC 3.0, VOOC 4.0 enables a 4000mAh battery to be charged to 67% in 30 minutes and 100% in 73 minutes, 12% faster than previous generation . A further optimized VFC algorithm serves to reduce the charging time required for charging the final 10% of battery capacity. OPPO has also reduced the internal resistance of the entire charging system and suppressed heat generation through efficient adapter and advanced battery cell design. Even if you play while charging, the temperature can be well controlled.
Positioned as the next generation Flash Charge solution for all, VOOC 4.0 boasts extensive compatibility. It can be compatible with all Flash Charge protocols prior to VOOC 3.0, and can achieve full load charging power of 5V4A (20W).
