CryoBoost's phone-cooling fan and heat-dissipating components keep your phone below 98°F during charging while other MagSafe chargers heat your phone to over 108°F. This cooling protects your battery, keeps charging speeds at their maximum, and ensures your phone stays cool to the touch.
Apple-certified 15W MagSafe charging and CryoBoost tech combine for even faster charging speeds. Standard MagSafe-style chargers create heat that slows down charging. CryoBoost keeps your phone cooler and charging speeds at their maximum so you can keep charging at 15W for longer.
Official MagSafe and Apple Watch certification let you charge your iPhone at 15W and Apple Watch at 5W, twice as fast as non-certified chargers. That means safer, more reliable charging at faster speeds and your everyday essentials fully charged even quicker.
