Advanced Cooling Technology: Featuring over-frequency refrigeration technology, this cooler directly targets the heat source for rapid cooling Comprehensive Heat Dissipation: The 360° circular air outlet ensures quick and accurate cooling, covering the entire phone surface Powerful Magnetic Attraction: Built with a strong magnetic ring, this cooler stays firmly attached, providing stable and efficient cooling Wireless Fast Charging: Enjoy 15W wireless fast charging while keeping your device cool during intense gaming sessions Innovative Design for Maximum Cooling: Equipped with a TEC semiconductor cooling chip and a frozen cooling surface, this device cools your phone faster than conventional methods Enhanced Cooling Surface: The high-conductivity cooling surface covers a large area, quickly lowering the phone's temperature for optimal performance Specifications: Minimum starting power: 3.3V±0.2V Fan and cooling plate start working (optimal working voltage is 9V) Power supply mode: Type-C USB Temperature requirement: When the indoor temperature is 27°C±1°C, the product temperature drops below 22°C within 30 seconds of operation, and the lowest temperature can reach 1-6°C under no-load state Size: 61x58.5x31mm Net weight: 72g Shell structure material: ABS Input power supply: Input interface type: Type-C Input: 5V/2A, 9V/2A, 9V/3A Working compatibility: non-inherent charging protocol Heat dissipation function:  Heat dissipation diameter: 43mm Cooling effect (25℃): 2-7℃ Cooling effect (30℃): 6-12℃ Note: 1. Connect the power supply to start cooling and fan operation, and press the side button once to switch on wireless charging. 2. Wireless charging supports up to 15W. When powered by 3.5V, it only supports 5W cooling mode. When powered by 9V or 12V, it supports 10W, EPP 15W. Cooling + wireless charging power is 15W. 4. Supports 7.5W wireless charging for iPhone. 5. Use QC, PD protocol charger. (That is, a mobile phone charger with fast charging) 6. The power supply line for the product must have a 4-core 3A or above data cable. If you use a C-to-C data cable, you need a 6-core data cable. 7. The charging power of wireless charging is based on the power that the mobile phone can achieve. (For example: many Android phones from Xiaomi and OPP have EPP15W standard protocol.) 8. Wireless charging LED light: ① The blue light is always on during wireless charging. ② When the wireless charger detects that the position of the mobile phone is abnormal, the blue light flashes. ③ When it is checked that there is no mobile phone, the blue light is not on
