Trending Wireless Charging Products in 2021: November Edition

Wireless charging is the transfer of energy from a power source to a recipient device without using wires or cables. It is a reliable and convenient method to charge consumer devices. Wireless charging of electronic devices is commonly done via inductive charging technology which uses electromagnetic induction to power devices. Magnetic coupling is another form of wireless charging technology that increases efficiency by allowing power transmission over longer distances. This article lists trending wireless charging products on everything RF in November 2021.
