Can the universal magnetic wireless charger 25W be plugged in all the time?

A universal magnetic wireless charger 25W refers to a charger that is not connected to a terminal device that needs to be charged using a traditional charging power cord. A universal magnetic wireless charger 25W is a device that uses the principle of electromagnetic induction to charge, and its principle is similar to that of a transformer. By setting the coils at the sending end and the receiving end, the sending end coil sends out electromagnetic signals under the action of electric power, and the receiving end coil receives the electromagnetic signals and converts the electromagnetic signals into electric current, so as to achieve the purpose of wireless charging.
Wireless charging technology obtained 20 patents in 2007, a variety of devices can use a charging base station, the wired charging of mobile phones, MP3 players, power tools and other power adapters will no longer exist.
