Background

In the prior art, besides the iPhone of apple, many other mobile phone manufacturers have also proposed mobile phones supporting Magsafe wireless charging, such as samsung, millet and the like. These phones also use apple-like Magsafe technology to charge by placing a magnetically attractive charger on a magnetic disk on the back of the phone. The design makes the charging mode of the mobile phones more convenient and quick, and is compatible with the Magsafe charger. However, due to apple company patent limitations, these manufacturers need to comply with related patent and regulatory compliance in designing and using Magsafe technology to ensure mutual compatibility and product quality.

The Magsafe wireless charger is a charger which uses magnetic force to be adsorbed on equipment for centering, and can be charged faster by using higher charging power and magnetic force positioning technology. However, the existing Magsafe charger is large in size, and there is some degree of magnetic leakage and interference to surrounding equipment.
