Oppo has long been a leader in the development of fast charging solutions – it has developed the technology behind the Dash Charge system, which is used in OnePlus phones, for example, and achieves even faster results on many of its own devices. Today, the company is taking another step forward with the announcement of a 125 W system, which it claims is the most advanced in the industry.
The headlines 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 so, this would surpass Oppo’s own record for quickly charging a battery of this size by about 1
Not only does a large power supply have to be built and connected to a normal telephone. The charger, the cable and the battery must be designed together for safety and efficiency reasons. According to Oppo, the phone, which is not yet a commercial product, uses double 6C cells with a “breakthrough battery ratio”, while the charger benefits from improved power density characteristics so as not to get too big.
Oppo has not yet announced a phone that ships with this technology, but often announces features like this before commercial products. The currently fastest rechargeable phone in the world is the Oppo Reno Ace with a 4,000 mAh battery, which I was able to fully charge in 31 minutes in my tests with its 65 W charger. Vivo, which shares ownership and technology with Oppo, announced 120 W technology last year that is said to charge a 4,000 mAh battery in 13 minutes but isn’t yet ready for delivery on every phone.
Oppo introduced wireless charging very slowly and only announced its first phone using this technology earlier this year. However, the company now claims to have the fastest wireless system. Oppo says the new 65W AirVOOC technology can wirelessly charge a 4,000mAh battery in 30 minutes, which would make it even faster than any currently available wired solution.
Oppo has developed a 65W AirVOOC charger, but there is no word about when it will be available or when phones will support it. The lack of wireless charging was really my only major complaint with the otherwise excellent Find X2 Pro flagship this year. Hopefully Oppo takes the function seriously.
Finally, Oppo rounds off its day of technical news loading with the announcement of some compact adapters that use GaN technology to reduce its size. There’s a 50W mini SuperVOOC charger that Oppo compares to the size of a business card holder, and a 110W mini flash charger that’s about the size of a normal 18W adapter.
