TEC semiconductor refrigeration breakthrough refrigeration technology high-power semiconductor refrigeration chip fast cooling, long burning time, full fire, immediately put into battle, no lag. Real room temperature freezing strong refrigeration uses semiconductor refrigeration, 5V 3A or above charging head can be frozen below room temperature 25℃, and does not block the air inlet and outlet. Rapid cooling freezing overclocking refrigeration system uses TEC refrigeration chip + built-in brushless motor + ultra-thin heat sink fins + superconducting refrigeration plate. Multi-function button one-button control gear switch short gear switch to adjust the cooling effect, short the light switch to adjust the lighting effect. High energy strong magnetic suction force this time it is really stable built-in strong magnetic suction ring, can provide about 500g suction force, firmly adsorb the phone without fear of falling, can not be thrown away at .
