How long has OPPO flash charging developed?

VOOC flash charging is completely independently developed by OPPO, with 16 patents. It adopts a revolutionary 4.5V low-voltage scheme, which increases the fastest charging speed by four times as never before. For Find 7, flash charging means that you can make a phone call for 2 hours after charging for 5 minutes; Charging 15 minutes, continuous call for 6 hours; After charging for 30 minutes, the power can directly soar to about 75%, which is enough for most people to use all day. There is no doubt that VOOC flash charging is the fastest mobile phone charging technology in the world! And it has solved the problem that the mobile phone heats up when charging, and neither the adapter nor the mobile phone will heat up again when charging. It can be seen that VOOC flash charging is also the safest mobile phone charging technology in the world! The 5pin interface of ordinary mobile phone can't meet the demand of high current and fast charging. OPPO spent 15 months trying six schemes, and finally found a solution and customized the 7pin interface. The R&D investment of 7pin interface alone is close to 65.438 billion yuan. In addition, OPPO added MCU to the adapter for the first time and developed a unique intelligent control program, which is the world's first adapter with a brain! OPPO has also deeply developed intelligent full-terminal five-level protection technology to realize low-voltage flash charging, so that you can sit back and relax completely when charging quickly.
