1. Breakthrough refrigeration technology, TEC temperature control chip, every part is , providing an upgrading experience beyond ordinary radiators 2. Semiconductor superconducting refrigeration plate, refrigeration speed is 6 times faster, and TEC refrigeration area is expanded by 3 times Close fit, increased cooling speed, seamless fit to the phone, high thermal conductivity cooling for even heat dissipation 3. Powerful turbo fan, silent cooling, 9-blade large angled fan blades for cooling 4. Silent noise reduction design, the sound is too small to be heard, decibels less than equal 25dB 5. Compatible with 99% of mobile phones on the market, regardless of model. With a back clip, the back clip is more convenient to remove, does not affect the heat dissipation of the phone, and is compatible with more models.
