Wireless charging is a hot topic in the tech world these days. With the push for more devices to be wireless, it's no surprise that charging them wirelessly is becoming more popular

So, how does wireless charging work?

Wireless charging is a method of powering electronic devices without wires or cables. It uses an electromagnetic field to transfer energy between two objects, usually a power transmitter and a receiver. Wireless charging is used in various applications, including cell phones, electric vehicles, and medical devices.

The technology behind wireless charging has been around for over a century, thanks to Nikola Tesla. Still, only in the last few years did it become widely available for consumer use. The most common wireless charging technique uses inductive charging, where an electromagnetic field transfers energy between two coils. One coil is linked to a power source, and the other is attached to the device that needs to be charged. When the two coils are affixed, a magnetic field is created that causes an electric current to flow between them. This current is used to set the device.

When you place your device on the charging pad, it creates a magnetic field. This magnetic field is then used to transfer energy to your device, which charges the battery. The charger must be placed close to the accused device so that the magnetic fields can align and the current can flow.

Most wireless chargers use the Qi standard, which includes several safety features to prevent overcharging and overheating. However, several other wireless charging standards are in development, and future devices may be compatible with multiple criteria. Some manufacturers, including Samsung, use the PMA standard. PMA-compatible chargers are typically not compatible with Qi-compatible devices.


The Qi standard uses inductive charging, an electromagnetic field, to transfer energy between the charger and the device. The PMA standard uses magnetic induction magnets to transfer energy between the charger and the device.

Wireless charging technology is becoming increasingly popular, as it offers a convenient way to charge devices without cables. There are several different ways that wireless charging can be used, and it is finding applications in a range of various industries.

One of the most common applications for wireless charging is in consumer electronics. Many smartphones and other portable devices now have wireless charging capabilities, and dedicated charging pads are widely available. This allows users to place their devices on the pad to charge them without fiddly cables.

Wireless charging is also being used in several public places, such as airports and coffee shops. This allows people to charge their devices while on the go without searching for a power outlet.

And here are some wireless charging devices that use the technology of electromagnetic field transfer.
