PRODUCT SPECIFICATION

Customer Name:————————–
Product Model No.: ————————–TH02
Product Type: Magnetic 4-in-1 Wireless Fast Charger Dock

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 a 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 a 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 Type-C interface for digital products. It  is perfectly compatible with apple 12 and 13. The charging process does not slide when using mobile phones.
   The platform can be used for earphones, mobile phones with wireless charging functions without magnetic absorption function or other digital products. Compatible with  Apple Watch 1-6 generation, power adaptive (that is, the adapter automatically adjusts the output power when the power is insufficient, but the charging effect will be affected)
   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 an iPhone 12, 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: for the first power on, the red, green, and blue light flash out 3 times. The blue light flashes 3 times when the phone is charging, and the green light flashes for 3 times when the charge is disconnected. There is no light indication for watch charging.
Touch Key Function: short (about 1 second) touch once, turn on the colorful circulating atmosphere light, short touch once again will stop in the current color, touch once again to turn off the light, long press touch (about 3 seconds) will turn on the 5V 1A output interface output red light flashing twice. Long press and touch again to close 5V 1A  output red light flashing 3 times.
FOD Foreign Object Detection: when there is a metal foreign object, the blue and green light flashes alternately and will keep protecting until the metal foreign object leaves the charging range.
Disassembly and assembly method: 1 Assembly: align the gap of the pole with the protruding buckle of the base and press it gently. When feeling resistance, rotate it gently to the left for 15 degrees.
2 Disassembly: Rotate 15 degrees to the right, gently lift up (transportation needs)

Charging range test

Automatic positioning adsorption of mobile phones, accurate docking, and quick charging.
The charging position of the platform is ±3MM, and the watch is magnetically charged without alignment.

Sensitivity Test

The first power on needs to wait for the light to flash, and the host program starts in about 3 seconds.
Automatic adsorption of mobile phones, accurate docking, and quick charging, response time is about 2 seconds, different brands of mobile phones are slightly different.
The response time of the watch charging is about 3 seconds (it depends on the electric quantity and the temperature of the watch)

Automatic Protection Function

When the transmitter detects that the load current connected to it is too large (the current exceeds the rated output value), the transmitter automatically shuts off the connection with the receiver for automatic safety protection. If dual 15W charging at the same time, the adapter function is insufficient and will automatically adjust the applicable output power. If the device is removed for 5 seconds and placed correctly during charging protection, it can enter the charging state again only after a successful connection.
