With a transmitting coil 2*3cm, the coil of the same size is received. The efficiency is about 58% when the distance is a few millimeters. The efficiency decreases rapidly with the increase of the distance. When the distance reaches 10 cm, the efficiency is only 30%. Power first I did 5W, but I only used 20 LEDs, so I guess the power is enough for 3W. Have you ever done this kind of gadget in your spare time? Come and exchange the income. This transmission method may It will be used a bit later, and it can be used to charge the battery in a mobile phone charging and fully sealed product.
