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 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 function 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 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 flashes out for
3 times. The blue light flashes for 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)

8. 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 charging state
again only after successful connection.
