Oppo announces 125W tech that charges phones in 20 minutes

From The Verge: Oppo has long been a leader in engineering fast-charging solutions — it developed the tech behind the Dash Charge system used in OnePlus phones, for example, and has achieved even faster results in many of its own devices. Today, the company is taking a further step forward with the announcement of a 125W system that it claims is the most advanced in the industry.

The headline figures of the system are that it can charge a 4,000mAh phone battery in 20 minutes and up to 41 percent in 5 minutes. If accurate, this would beat Oppo’s own record for fast-charging a battery of that size by around 10 minutes.

This isn’t simply a matter of building a big power adapter and plugging it into a regular phone — the charger, cable, and battery itself need to be designed together for safety and efficiency. Oppo says the phone, which isn’t yet a commercial product, uses double-6C cells with “breakthrough battery ratio,” while the charger benefits from improved power density properties so as not to grow too large. It uses USB-C at both ends of the cable, unlike Oppo’s previous USB-A VOOC chargers.

Oppo hasn’t announced a phone that will ship with this technology yet, but it often announces features like this before commercial products. The current fastest-charging phone in the world is the Oppo Reno Ace, which has a 4,000mAh battery that in my testing I could fully charge in 31 minutes with its 65W charger. Vivo, which shares ownership and technology with Oppo, announced 120W tech last year that can supposedly charge a 4,000mAh battery in 13 minutes, but it’s yet to ship on any phone.
