Coil is circularized using enamel insulated wire coiling, close-packed arrays between coil and coil.
In use, pressure stabilizing output USB interface is connected with the USB interface of the electronic equipment to charge is needed, can start
Wireless charging is carried out to electronic equipment.
The effect of booster circuit is: transmission power amplifying circuit converts electrical current into electromagnetic field emissions and goes out, with transmitting
The increase of distance, magnetic field energy will decay, produced when such electromagnetic field receiving coil receives magnetic field reconvert into voltage
Voltage can be more much lower than the voltage of transmitting terminal, such as transmitting terminal operating voltage 12V, is received by 0.5 meter of receiving end distance emitter
Device can export 5V voltage and charge for mobile phone, but when 1 meter of receiver distance emitter, since distance produces voltage
Decaying, receiver can only export 3V voltage, just be not enough to charge to mobile phone, so 12V is inputted electricity using booster circuit
Pressure boosts to 30V or so, and when 1 meter of receiver distance emitter or so, receiver still can export the voltage of 5V or more.
The effect of transmission power amplifying circuit is: small-power high frequency oscillation signal is converted into high-power high-frequency concussion letter
