ESR Unveils 25W CryoBoost Wireless Charger and Corning Glass Protectors at IFA 2026
The accessory maker targets thermal throttling in flagship devices with active cooling and premium materials.
ESR Tech unveiled a new suite of high-performance accessories at IFA 2026 in Berlin, centering on a high-wattage wireless charger designed to combat heat. The launch signals a strategic shift toward premium hardware integration to support the next generation of flagship smartphones.
At the core of the showcase is a 25W wireless charging pad that supports the Qi2.2 standard. To maintain these peak speeds, ESR integrated its proprietary CryoBoost system, which utilizes active cooling to prevent the overheating that typically triggers software-led charging slowdowns. Alongside the power hardware, the company introduced a new line of screen protectors manufactured from Corning glass, specifically engineered for the iPhone 17 Pro Max and the Samsung Galaxy S26 Ultra to improve scratch and drop resistance.
The Battle Against Thermal Throttling
Wireless charging has long struggled with efficiency due to heat generation. As standards like Qi2.2 push for higher wattage, the resulting thermal energy often forces smartphones to throttle their intake, significantly increasing the time required to reach a full charge. ESR has been expanding its CryoBoost line to address this specific bottleneck. By incorporating active cooling mechanisms—such as fans or semiconductors—the company aims to stabilize device temperatures, allowing the hardware to sustain 25W speeds without the typical thermal pauses.
Positioning for the Premium Market
This move positions ESR as a high-end alternative to standard MagSafe and Qi accessories. By partnering with Corning for its screen protectors and investing in active thermal management, ESR is directly targeting users of the most expensive flagship devices. The integration of industrial-grade materials and active cooling suggests a move away from passive plastic accessories toward engineered hardware that complements the sophisticated thermal envelopes of the iPhone 17 and Galaxy S26 series.
Future Outlook
Industry observers will now watch to see if active cooling becomes a standard requirement for all high-wattage wireless chargers as Qi standards continue to evolve. While the 25W CryoBoost system addresses current thermal limits, the long-term adoption of such hardware depends on whether users prioritize charging speed over the added bulk and power requirements of active cooling systems. It remains to see if other accessory makers will follow suit with similar active thermal solutions for the 2026 device cycle.
