Oppo announces 125W technology that charges phones in 20 minutes

Oppo has long been a leader in fast-charging solution engineering – developing the technology behind the Dash Charge system used in OnePlus phones, for example, and achieving even faster results on many of its own devices. Today, the company is taking it one step further with the announcement of a 125W system that it claims is the most advanced in the industry.

The main figures of the system are that it can charge a 4,000 mAh phone battery in 20 minutes and up to 41 percent in 5 minutes. If necessary, this would break Oppo’s record for quickly charging a battery of that size in about 10 minutes.

This is not simply a matter of building a large power adapter and plugging it into a regular phone – the charger, cable, and battery itself should be designed together for added safety and efficiency. Oppo says the phone, which is not yet a commercial product, uses 6C dual cells with an “innovative battery ratio”, while the charger takes advantage of the improved power density properties so as not to overgrow. It uses USB-C on both ends of the cable, unlike Oppo’s previous USB-A VOOC chargers.

Oppo has yet to announce a phone that ships with this technology, but it often announces features like this before commercial products. The world’s fastest charging current phone is the Oppo Reno Ace, which has a 4,000 mAh battery which in my tests I was able to fully charge in 31 minutes with its 65W charger. Vivo, which shares ownership and technology with Oppo , announced last year a 120W technology that is supposed to be able to charge a 4,000 mAh battery in 13 minutes, but it still doesn’t ship to any phone.

Oppo has been extremely slow to embrace wireless charging, only announcing its first phone to use the technology earlier this year, but the company now claims to have the fastest wireless system, too. Oppo claims that its new 65W AirVOOC technology can wirelessly charge a 4,000 mAh battery in 30 minutes, which would even make it faster than any wired solution currently available.

Oppo has designed a 65W AirVOOC charger, but it is not known when it will be available or when phones will support it. Lack of wireless charging was really my only major complaint with this year’s excellent Find X2 Pro flagship, so I hope Oppo takes the feature seriously.

Finally, Oppo is completing its tech news load day by announcing a pair of compact adapters that use GaN technology to reduce their size. There’s a 50W SuperVOOC mini charger that Oppo compares to the size of a business card holder, along with a 110W mini flash charger that’s about the size of a normal 18W adapter.
