Wireless Charging Module 5V/2A
US$16.25
This is a wireless charging module based on “magnetic-coupled resonance” technology that only consumes one-millionth of the power of traditional electromagnetic induction power technology. When the transmitter is electrified, it does not emit electromagnetic waves but forms a non-radiating field magnetic field around it. This magnetic field is used to connect with the receiving end and excite resonance at the receiver, by which the energy can be transmitted with minimal power consumption. Transmitting efficiency can reach up to 90%.
