What is Cryoboost:ESR Wireless Cryoboost Charger with cool fan

The biggest enemy of fast wireless charging isn’t the cable—it’s heat. Standard MagSafe chargers cause iPhones to heat up rapidly, triggering Apple’s safety protocols that throttle charging speeds to a crawl. This is why your phone often feels hot while barely gaining any charge.

CryoBoost™ is our engineered answer to that bottleneck. We didn’t just build a charger; we built an active cooling system. By integrating a high-powered cooling fan and precision thermal components directly into the charging pad, CryoBoost™ pulls heat away from your iPhone the moment it snaps into place.

The result? Your phone stays cool even while binge-watching videos or using GPS navigation. While other chargers slow down to protect the battery, CryoBoost™ maintains peak 15W charging speeds, getting you to 100% significantly faster than official MagSafe alternatives. It’s the only way to charge while using your phone without triggering overheating-related charging slowdowns.
