In this article, we’ll explore the world of wireless charging and uncover the devices that can take advantage of this technology.
The Basics of Wireless Charging
Before we dive into the list of devices that can be charged wirelessly, it’s essential to understand how wireless charging works. Wireless charging uses electromagnetic fields to transfer energy between a transmitter (the charging base) and a receiver (the device to be charged). This technology is based on the principle of electromagnetic induction, which was discovered by Michael Faraday in 1831.
There are three main types of wireless charging:
Qi (Inductive Coupling)
Qi (pronounced “chee”) is the most common type of wireless charging. It uses a coil in the charging base to generate an electromagnetic field, which induces an electromotive force (EMF) in the receiver coil in the device. This EMF is then converted into electrical energy, which powers the device.
Rezence (Magnetic Resonance Coupling)
Rezence is a wireless charging technology that uses a resonant coil in the charging base to generate a magnetic field. This field is then coupled to a resonant coil in the device, which converts the magnetic energy into electrical energy.
Radio Frequency (RF) Charging
RF charging uses radio waves to transfer energy between the charging base and the device. This technology is less common than Qi and Rezence but is gaining popularity.

How does wireless charging work?
Wireless charging uses electromagnetic fields to transfer energy between a charging base and a device. When a device is placed on a wireless charging pad, the pad generates an electromagnetic field that induces an electrical current in the device’s receiver coil. This current is then used to charge the device’s battery. The technology is based on the principle of electromagnetic induction, which is the same principle used in transformers and other electrical devices.
The charging process is typically initiated when the device is placed on the charging pad and aligned with the pad’s transmitter coil. The device then detects the electromagnetic field and begins to draw power from the pad. The charging process is usually slow and efficient, allowing devices to charge safely and reliably without the need for a physical connection.
Is wireless charging slow?
Wireless charging can be slower than traditional wired charging, depending on the device and charging pad being used. However, the difference in charging speeds is often negligible, and many modern wireless charging pads can charge devices at rates comparable to traditional wired charging.
