Mophie’s StealthCharge is a new wireless charging design that moves heat-generating electronics from the charging pad into the stand’s base, keeping your iPhone cooler while maintaining full charging speeds. Unlike most MagSafe chargers, it reduces heat without noisy cooling fans, resulting in faster, quieter and more consistent wireless charging. Who is it for? Apple users wanting fast, cooler multi-device charging with minimal desk clutter, especially iPhone 16 owners and anyone charging a MacBook too. Mophie’s StealthCharge is a new wireless charging design that moves heat-generating electronics from the charging pad into the stand’s base, keeping your iPhone cooler while maintaining full charging speeds. Unlike most MagSafe chargers, it reduces heat without noisy cooling fans, resulting in faster, quieter and more consistent wireless charging. Wireless charging is so fast these days that it’s catching up with wired cable charging. The only thing holding wireless charging back from truly catching up with wired cable power is the inefficiency of heat that can force the device being charged to slow the charger down when it gets too hot for the phone’s good. Mophie, a pioneer in phone charging since the beginning, has come up with a novel solution that’s so simple it seems strange that it’s not commonplace. It calls its new technology StealthCharge, and its first products are a range of multi-device chargers: the 3-in-1 and 4-in-1 Wireless Charge Stands and another folding travel charger called Roam . Why wireless charging usually generates heat Wireless charging is convenient because it eliminates the need to find the right cable when your phone needs a boost of power. It has improved rapidly with Apple’s MagSafe technology that corrected charging coil misalignment between phone and charger. MagSafe and its third-party Qi2 and Qi 2.2 offspring have progressed the coil alignment to reduce the magnetic field not transferring energy (electromagnetic induction) efficiently, which otherwise can generate heat. Temperature is a battery’s nemesis. To protect its battery, your phone’s thermal management system automatically throttles charging speeds when the heat risks damaging it. This throttling slows down charging. To reduce this heat problem and maintain a steady charge, some manufacturers install fans near the charging pads, but this can create unwanted noise as the fans struggle to reduce the heat. Simon Jary How StealthCharge reduces heat Mophie’s solution is clever because, like many of the best challenge beaters, it’s simple. I’m sure the engineering isn’t simple, but the idea is. StealthCharge moves the hottest components from the charging pad itself (in direct contact with the phone) to the product’s base. In effect, the base now serves as a heat sink to dissipate heat more efficiently. The power is then sent to the charging pad via the stand’s stem. StealthCharge relocates the following components: Integrated controller circuitry , including the 25W Qi2.2 controller integrated circuit Power Delivery (PD)…
