3 Test items and report
3.1 wireless transmission test items
3.1.1 system efficiency:
The ratio of output power to input power is the actual efficiency of wireless charging.
3.1.1.1 test method: connect the DC power supply, adjust the input voltage to 5.1V, connect the output of
the receiving end to the load meter, and the load meter outputs in a constant current way, and adjust the
output to 1a with 100mA as a gear.
3.1.1.2 precautions: the wiring from DC power supply to product input terminal shall be as short and
thick as possible to reduce DC loss. The measured input voltage point shall be placed at the product
interface, and the actual input voltage shall prevail. Similarly, the wiring from the output terminal to the
load meter shall be as short and thick as possible, and the output voltage shall be subject to the output
terminal voltage of the receiver. The effective distance between the transmitter and the receiver is about
2 ~ 4mm, so as to achieve the best test results 
