• Wireless charging=transmitter+receiver 1. Mobile phone has wireless charging function: If the phone comes with wireless charging function, it can be charged wirelessly by tapping the transmitter directly 2. Mobile phones do not have wireless charging function: If the phone does not have its own wireless charging function, it is necessary to simultaneously capture the receiver and transmitter to achieve wireless charging. Product parameters: Transmission distance: 0-10mm Input power supply: Type-C port: 5/9/12v/QC3.0 Soldering wire: 5/9/12V, can be powered by a power adapter Charging power: Input 5V, output 5W; Input 9V, output 15W Input 12V/QC3.0; Output 22W-5W automatic recognition Coil size: diameter 50mm * thickness 2.5mm PCB size: 35 * 35 * thickness 4.5mm Executive standard: QI wireless charging standard Product certification: CE/KC/FCC/ROHS and other certifications Safe and fast charging · 6 major protections Built in MCU and charging management lC chip) Overcurrent protection: prevent excessive charging current Overvoltage protection: prevent excessive charging voltage Over temperature protection: prevent charging temperature from being too high Overpower protection: prevent excessive charging power Undervoltage protection: prevent charging voltage from being too low Short circuit protection: Automatically cut off the circuit in case of a short circuit The temperature during charging is 5-10 ° C lower than that of similar solutions Frequently asked questions: Q: Is the coil divided into front and back sides? How is the correct placement? Answer: The transmitting coil is facing the receiving end of the phone (placed on the back) Q: What is the charging speed of 5V input? Answer: The 5V input is a 5W output, and fast charging is only available for 9/12V input. In addition, the USB port voltage of the car is 5V, and an onboard fast charging head is required to quickly charge. Q: Can the black porcelain chip on the back of the wireless charging coil be removed? Answer: No, the black porcelain plate on the back of the coil is a magnetic separator. Removing it will cause the wireless charger to malfunction. Micro cracking of ceramic tiles does not affect charging.
