Working status indication
Charge Status Indication
| Charger Status | Power On | Standby | Charging | Battery Full | Fault |
|---|---|---|---|---|---|
| Blue LED | Blink（1Hz）1 time | OFF | ON | OFF | Blink（1Hz） |
The transmitter has five working states, namely, power on, normal standby, normal charging, full power and failure. After the power on, the red light is always on, and the green light does not glow after flashing 1 times; When the normal standby, the red light is always on; When charging normally, the green light is always on and the red light is off; When abnormal or malfunction occurs, the green light blinks and the red light goes off. Abnormal phenomena include over-offset location of the receiver, over-high PCBA temperature, entry of metal foreign matter, overcurrent of input current, and overvoltage of input voltage, etc.
Protection Character
Input Over-Current Protection
The Qi transmitter has the input current overcurrent protection. Once the overcurrent fault is triggered, the transmitter will automatically shut down and restart, and try to reconnect. If the overcurrent protection is triggered for many times, the system will stop working and flash the light to alarm
Coil Over-Current Protection
The Qi transmitter has the primary side coil current overcurrent protection. Before entering the power transmission stage, once the overcurrent fault is triggered, the transmitter will automatically shut down and restart to try to reconnect. If an overcurrent is triggered after entering the power transmission stage, the emitter will automatically adjust the current to below the current limit point.
Foreign body detection Protection FOD Protection
The Qi transmitter has the function of foreign body detection. When the transmitter enters the power transmission stage, a metal foreign body entering the charging area will be recognized. The transmitter will self-lock until the receiver moves away, and the charger will automatically resume its normal working state.
Over-Voltage Protection
The QI transmitter has the function of over-voltage protection. When the DC voltage of the transmitter exceeds a certain value (9.7V), the transmitter will stop working in time to protect the circuit safety. Once the voltage drops to the allowable operating range (9.5V), the transmitter will automatically return to its normal operating state.3.5 UVLO
UVLO
The Qi transmitter has the function of under-voltage protection. When the DC voltage of the transmitter is lower than a certain value (4.3V), the transmitter will stop working, so as to protect the components and chips from damage. When the voltage is restored to the allowable operating range (4.4V), the transmitter will automatically resume its normal working state.

Test Instruction
Mobile phone test
The wireless charging performance of a mobile phone is greatly affected by its own temperature. When the temperature is above a certain value the phone will not draw power and thus the power will not increase, or even overheat to protect and stop charging. Therefore, when testing the wireless charging of mobile phones, it is necessary to avoid testing in confined and narrow spaces, as well as avoiding overheated ambient temperatures. The wireless charging performance of the phone will be better when the ambient temperature is below 25°C.
When multiple devices are used
When multiple devices are used at the same time, the center points of the coils need to be more than 35 cm apart from each other, otherwise they may affect each other and cause unstable charging.
Additional Notes
- Avoid placing any metal on the heating surface during working.
- Avoid placing magnetic stripe card on the heating surface which can easily damage the card.
- Make sure that the thickness of the upper desktop is within the range of thespecification, otherwise it will not be able to charge.
- Avoid humidity, liquid, fire and high temperature as it may cause hazard to users.
- Do not try to disassemble or modify the product.
- Do not attempt to disassemble to avoid fire hazard or short-circuit
- Any of damage by abnormal use of product will void the manufacture warranty.
- Do not use product when the cord is damp, damaged or loose as it may cause short circuit and overheat.
- Do not handle the power cord with wet hands or pull the built-in cable.
- Contact with overheated equipment may cause discoloration or surface damage.
- Keep to other electrical devices such as Microwaves, sufficient distance.
