Product Description


  This mode using the electromagnetic principle to qi wireless charging with smart watch smart balance ,  the charging distance coil to coil is 4mm , charging efficiency 50% . 

 it can full support wireless quick charge battery within 2 hours;At the same time it has good compatibility with 5W wireless charger , and it can support Ti, IDT, PANASONIC, and others Qi standard receiver. 

  Power input 5V1A power control IC driver MOS transistors (Drive circuit),MOS push-pull resonant capacitance and inductance, issued 50V voltage 105-189K shock power,Communication module detects the received feedback information to the MCU,Feedback information processing modulation frequency is 500-1000Hz,At the same time electrical detection module will send back to the transmit power MCU,MCU based on feedback to adjust the transmit frequency,The circuit control within a certain range. Wherein the main operating frequency is 48MHz.LED have blue and green color, the power will turn every 0.5S bright look.Standby completely destroyed, charging blue lights up, full of green light.when an error occurs, double light flashing.
