Electric Character 5. Charging Range Test 6.Sensitivity Test 7. Reliability Test 8. Automatic Protection Function 9. Product Outline 10. Disclaimer 1. Product Function 1.Wireless charging function introduction This product realizes short distance radio transmission through magnetic induction mode, and adapts to PD protocol QC2.0 protocol double 9V 1.5A digital product charging and communication, furniture, fire, waterproof and other digital products. The product conforms to the Qi wireless charging standard. Mobile phones compatible with the Qi standard can use this product to charge, supporting the quick wireless charging function. This product has unique appearance and wide working voltage (DC9V-12V). It is suitable for adapters that comply with PD protocol and QC protocol (PD protocol is preferred, 9V is the default value of this product when using PD adapter). Features: maximum 15 watt output for two mobile phones (or 1 mobile phone +1 earphone) and a watch with an output of 5V 1A USB-A interface for digital products. It is perfectly compatible with apple 12 and 13. The shield position magnetic automatic absorption, no need to align position. The charging process does not slide when using mobile phones. The platform can be used for earphones, mobile phones with wireless charging function without magnetic absorption function or other digital products. Compatible with Apple Watch 1-7 generation, power adaptive (that is, the adapter automatically adjusts the output power when the power is insufficient, but the charging effect will be affected. The USB-A power is not included in the wireless charging power. That is, the maximum power of wireless charging is about 30 watts, and USB-A is 5 watts. When the adapter power is insufficient, protection disconnection charging will be carried out.) When the device is fully charged, if the phone is not removed for a long time, the phone will keep the power at 100% (supplementary charging). 2. Basic Operation Tips: The larger the deviation distance, the lower the charging efficiency. It is recommended to use QC protocol 9V 3A or PD protocol adapter and data line with current 3A or above, PD protocol adapter is preferred. Usage: Connect the transmitter USB cable, the product works in fast wireless charging mode, supporting double 15W load. If the object is iPhone 12/13 or with magnetic phone cases, there is no need to align the device with automatic adsorption and pop-up charging. If the platform position is placed at the center of the receiving coil on the mobile phone end (anti-skid ring), the center of the transmitting coil is offset from the allowable distance (±3mm). If the deviation is too large, the transmitter will not work, and the phone needs to be correctly placed again, and the device will re-enter the charging state. The watch can be placed directly in the charging position. Indicator Light Description: The power standby indicator (spaceman's eyes) is on, another color is on when wireless charging is working, indicator lamp will not off when power on. FOD foreign body detection: there is a metal foreign body light flashing, and protect until the metal foreign body leaves the charging range. Spaceman shape: The head can be rotated from side to side at an Angle of about 30 degrees. Disassembly method: 1.) Assembly: Aim at the base gap and press down the spaceman, and hear a click sound. 2.) Disassembly: Hold one leg of the spaceman and push it up against the base with your thumb (transportation needs) 3.
