Last week, Xiaomi announced its Mi Charge Turbo 30W wireless charging technology, a significant upgrade to its 20W wireless Mi Charge Turbo that it announced earlier this year. Today, OPPO announced its own 30W wireless VOOC Flash Charge technology to rival Xiaomi’s.
The new wireless charging technology will now tie with Xiaomi’s Mi Charge Turbo for the crown of highest-rated wireless charging technology.
Zhang Jialiang who heads OPPO’s Flash Charge division said at the announcement that the wireless charging technology can charge a 4000mAh battery from empty to full in 80 minutes. This is slower than Xiaomi’s own which charges a 4000mAh battery in 69 minutes.
He also revealed that the charging temperature is controlled and does not exceed 40°C. The wireless charging technology uses a custom wireless charging chip, has foreign object detection and five protections built-in.
The 30W Wireless VOOC Flash Charge technology actually charges at 20V 1.5A but also supports 5W and 10W wireless charging. OPPO said in the official press statement that it “uses real-time adjustment of the charging process and efficient charging components to ensure a more efficient and safer charging while avoiding overheating.”
Mr. Zhang said the wireless charging technology will soon appear in a commercial product but did not specify which of its upcoming phones it is.
