Wireless Charging Module 5V/300mA (DFRobot)

Introduction

Wireless charging uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.

This is a new wireless charging module, which could provide 5V@300mA (MAX 600mA) power output. It is using the new technology "resonant magnetic coupling, which will reduce the electricity consumption during power transmission. The transfer efficiency could arrive at 90%. It could meet your most project requests.

Wireless power supply technology (wireless charging) allows the receiving end to transmit power through air, paper or plastic casing. Our wireless power supply uses the magnetic coupling resonance technology, which consumes only the traditional electromagnetic induction power. One-millionth of the technology, when the transmitter is energized, it does not emit electromagnetic waves outward, but only forms a non-radiative magnetic field around it. This magnetic field is used to communicate with the receiving end to excite the resonance at the receiving end to transfer energy at the expense of little consumption. In this technique, the strength of the magnetic field will not be similar to the strength of the Earth's magnetic field, and people do not have to worry about the adverse effects of this technology on their bodies and other equipment. 
This module is designed with the latest high-current wireless power supply chip. The circuit is the simplest. When the 5V low-voltage power supply is used, it can output 5V@300mA current at the receiving sensor. If the loss is received in addition to the rectifying and stabilizing circuit, the transmission transmission efficiency is as high as 90%.
