How Does a Wireless Charger Work?

Wireless technology has taken over many elements of consumer IT, with wireless headphones, keyboards, and mice being very popular. New wireless charger technology has taken off in recent years as it is more convenient and flexible between many devices than wired systems. This technology has a series of benefits, it is a universal approach that eliminates a variety of proprietary charging cables and the connections are much safer with no physical component in in-desk modules.

From a physics approach, wireless charging uses the principle of electromagnetic induction. This concept has been known since the 19th century, but it has not been implemented effectively until recently. Put simply, a wireless charger takes in electricity and produces an oscillating (constantly changing) magnetic field. When a capable device is inside this field, the field will create, or “induce” a current in its receiver coils; this current can then charge the battery. Many newer phones are compatible with this technology for in-desk modules (meaning they have the needed components installed) including iPhone 8 and above and many Samsung Galaxy models after 7.

Wireless charger technology has been somewhat limited in the past, with many only working for devices in close contact. More recent models such as in-desk modules are capable of passing through wood surfaces and charging at longer ranges, top-end models working up to a foot away. They are also slightly less efficient than using wired charging methods, about 80% as energy efficient. These limitations are vastly outweighed by the benefits of universal and safe connections.
