Oppo has thrown down the gauntlet in the race to speed up smartphone charging. The Chinese brand has just announced 125W Flash Charge and 65W wireless charging – its fastest solutions to date. The 125W charging technology can fully juice up a 4,000mAh battery in as little as 20 minutes, according to the company. That’s slightly slower than what sister brand iQOO promised with its upcoming smartphone. Oppo stressed that its new charging solution is compatible with all previous products based on its proprietary VOOC protocol, as well as mainstream protocols like USB Power Delivery up to 65W. Powering up with a cable is generally faster than wireless charging, but Oppo is catching up quickly. Its new Qi-compatible 65W AirVOOC charging solution is said to be able to charge up a 4,000mAh battery in 30 minutes. In comparison, it takes just as long for OnePlus’ Warp Charge 30 Wireless charger to boost the OnePlus 8 Pro’s 4,510mAh battery to 50 per cent. Oppo hasn’t said when it will ship these new technologies, though it did show off a concept design for a 65W wireless charger. The company also introduced two portable chargers on Wednesday. The 50W mini SuperVOOC charger is designed for users to charge smartphones or laptops on the go. It’s around 1cm thick and fits easily inside a shirt pocket. The 110W mini charger is slightly thicker.
