The 320-watt fast-charging technology, dubbed ‘320W SuperSonic Charge’, was developed by Chinese consumer electronics company Realme and beats out previous chargers. Smartphone maker Redmi had previously unveiled a 300-watt technology to charge up a device in four minutes and 55 seconds in 2023, but no manufacturer has since been able to go beyond this, until now. Realme representatives demonstrated the new technology at the Realme 828 Fan Festival event in Shenzhen, China, on 14 August. The record-breaking fast-charging capability can power up a smartphone’s battery to 26 per cent in one minute and to 50 per cent in less than two minutes. It takes four minutes and 30 seconds to fully charge a smartphone.
