Cool down quickly. Temperature drop. turbo cooling. battery protection. RGB colorful lights. Worry-free bass. Heat dissipation type: Semiconductor refrigeration. Voltage and current: 5V2A. Material: ABS PC aluminum alloy. Features: After more than ten hours of continuous live broadcast, the heat dissipation is still good. The mobile phone only needs a clip to cool down, and the temperature can be directly lowered by 5°C when the phone is turned on. Dual-core semiconductor cooling film, dual fans and double fins, silicone non-slip mat, low power consumption design. Charging and cooling without delay. Comes with bracket access port, can be used with universal wheel bracket, bracket access port. Support bracket modification, gimbal modification, universal wheel accessories, suitable for 1/4 screw head and universal wheel modification. The live broadcast is smoother and more durable, which solves the problem of long-term live broadcast heating. The width can be extended to 88mm, and the buckle can be stretched, flexible and compatible to meet the needs of multi-size equipment. Instructions for use: Real-time temperature display, ideal temperature can be set manually. After turning on the machine, it drops to 5°C to reach the preset temperature, enters the smart energy-saving mode, the fan stops, and starts cooling every 90/s → energy-saving cycle. Press or - to adjust the temperature. Temperature control range: 0-40°C, the maximum temperature drop is 15-20°C (depending on the outside temperature). After booting, press and hold the switch button 2/s to boot.
