Alongside SuperVOOC 2.0 (65W) and 30W Wireless VOOC Flash Charge, OPPO also announced VOOC 4.0 Flash Charge Technology; a successor to VOOC 3.0.
VOOC 4.0 will also bring 30W charging to devices but via wired charging. It surpasses Xiaomi’s 27W Mi Turbo Wired Charging. OPPO says the new technology is the Flash Charge solution for all.
The new charging solution will allow users to charge a 4000mAh battery to 67% in 30 minutes and to 100% in 73 minutes – a 12% increase in speed compared to the previous generation. OPPO adds that the optimized VFC algorithm helps reduce the charging time required for the last 10%. The charging technology also features reduced internal resistance and reduced heat generation thanks to an efficient adapter and an advanced battery design. With VOOC 4.0, the temperature is controlled even when playing a game and charging at the same time.
VOOC 4.0 is also backward compatible with all Flash Charge technologies up to VOOC 3.0, so you are fine using a VOOC 4.0 charger for your older devices.
OPPO also revealed that the new technology will appear first in the upcoming OPPO K5, a successor to the OPPO K3. This is the first time we are hearing of the device. So other than the new charging technology, we practically know nothing else about it. We expect more details will surface soon.
VOOC technology was first launched in 2014 and now OPPO has filed over 1700 patents related to the technology. It is now used in over 30 devices and serves more than 145 million users. OPPO has also licensed the technology to other companies.
