FAQ

Most KryoZon coolers are powered via USB-C or USB-A. A standard 5V/2A adapter or any USB port on your laptop will work for most models. The H7 Cooling Pad benefits from a higher-wattage adapter (12V/2A or USB-C PD) for maximum cooling performance. Check your product page for specific requirements.

Yes. All models can run from a standard USB port. However, for maximum TEC cooling performance on models like the H1 MAX and H7, a dedicated power adapter is recommended.

Phone coolers (S9, S6, K12) use their own power source �� they do not draw power from your phone. You'll need to connect them to a USB power source separately.

The H1 MAX and H1 PRO support laptops from 11" to 17". The H4 PRO and H7 Cooling Pad support 12" to 17" laptops. Check individual product pages for exact size ranges.

The K12 uses magnetic attachment and works best with MagSafe-compatible cases or without a case. The S9 and S6 use a clip-on design that works with most cases up to 3mm thick.

Yes. All KryoZon phone coolers are universal and work with any smartphone regardless of brand or operating system. The K12 magnetic cooler provides the best experience with MagSafe-enabled devices.

Our semiconductor TEC models can reduce surface temperature by up to 22��C below ambient �� independently lab-verified. Actual results depend on the device, workload, and environmental conditions.

TEC stands for Thermo-Electric Cooler. It uses the Peltier effect to actively pump heat from one side of a semiconductor chip to the other, creating a cold plate that can go below room temperature. This is fundamentally different from fans, which can only cool down to ambient temperature at best.

Most models operate at 25dB or below �� quieter than a whisper. The S9 water-cooled phone cooler is completely fanless and silent.
