Cooling principle:
After the semiconductor refrigeration chip is powered on, it makes heat while cooling, blowing away the heat at the same time, so as to keep the cooling side at a low temperature.
1. Turbines on both sides gather wind, with super strong wind.
2. Four places are windy, and the wind is out from up to down.
3. 4000mAh large capacity battery, super long endurance.
4. Carry a small air conditioner and experience ice cooling.
6. Silicone connection, deformation inlet, easy to wear.
7. Type-C interface, front and back can be plugged, which is easier to use
