When charging, the charging core creates an electric field in the surrounding environment, then connects the replacement receiving end with the design that needs to be charged, and the charger starts charging the device. The ring will emit red light to remind the charge is complete. As long as the mobile phone is placed within the electric field coverage, no matter where it is, it will not affect the charging effect.
Recently, a Finnish company has designed a unique charging device for the iPhone, iPad, iPod and other Apple products. This wireless charger is composed of two parts: the receiving end of the ring and the charging core. Although the company said it was designed for Apple products, the charger is also suitable for other music players and computers.
