ESR has released the CryoBoost 3-in-1 magnetic charging station designed to cool iPhones while they charge wirelessly [1].

Overheating during fast wireless charging often leads to throttled performance and slower charging speeds. By integrating active cooling technology, this station aims to maintain optimal device temperatures to ensure consistent power delivery and hardware safety [1, 2].

Rosemary Orchard and Mikah Sargent demonstrated the device on the iOS Today program by TWiT [1]. The station utilizes CryoBoost technology to dissipate heat, which is particularly useful during high-temperature days or intensive use [1].

Technical specifications for the device vary by measurement. The charging station is described as a 100W unit [1], while the wireless charging output is rated at 25W using the Qi 2.2 standard [2]. This combination allows for high-speed energy transfer without the typical heat buildup associated with magnetic chargers [2].

According to reviews published in November 2025, the station can charge compatible Apple devices in approximately 30 minutes [3]. The 3-in-1 design allows users to power multiple accessories simultaneously, reducing the number of cables required on a desk, or nightstand [2, 3].

The product was reviewed by industry outlets on Nov. 17, 2025 [2]. It targets iPhone users who experience thermal throttling during fast-charging cycles, providing a hardware-based solution to a common software and physics challenge [1, 2].

The introduction of active cooling in consumer charging stations addresses a primary limitation of the Qi 2.2 standard: heat. As wireless charging speeds increase, the resulting thermal energy can trigger iPhone safety protocols that slow down charging. By removing heat externally, ESR allows the device to maintain peak charging speeds for longer durations, potentially extending the long-term battery health of the phone by reducing heat-induced degradation.
