Apple has told third-party accessory makers that they must use the fast-charging Apple Watch module in all future accessories, according to a report from AppleInsider.
Fast charging was introduced with the Apple Watch Series 7 in 2021. It enables the Apple Watch Series 7 and Apple Watch Series 8 to charge quickly, from empty to 80 percent in around 45 minutes. The Apple Watch Ultra also has fast charging, but needs about an hour to go from empty to 80 percent.
