What is Wireless Charging? How Does Wireless Charging Work?


Wireless charging has become pretty common these days. With the addition of Qi wireless charging in Apple’s iPhone 8, iPhone 8 Plus, and iPhone X, wireless charging is expected to increase in popularity. Some Android phones, such as Samsung’s Galaxy Note 8, Galaxy S8, and Galaxy S7, include it.

Wireless charging uses a magnetic field instead of a conventional power connection to charge electrical gadgets. It’s also known as inductive charging or wireless charging.

How Does Wireless Charging Work?

Wireless charging is based on the successful transfer of energy by electromagnetic induction between a transmitter and a receiver. This phenomena involves inducing an electric current by modifying the magnetic field. Finally, this allows for the wireless transmission of power to an electronic device.

An electromagnetic coil in the wireless charging base transmits a magnetic field. Another smaller coil placed within a compatible device, like as a smartphone, picks it up. The smartphone’s circuit transforms this energy into battery backup after it has been collected.

What You Need for Wireless Charging ?

You’ll need a wireless charger and a compatible smartphone to charge your phone wirelessly. Wireless chargers are available in a variety of shapes and sizes, ranging from big mouse mats to small discs built into furniture.

Is Wireless Charging Faster?

The answer is simple: no. In most circumstances, wireless charging is slower than using a cable to charge your smartphone or tablet.

There are, however, several wireless chargers on the market that are meant to charge faster. They are fitted with modern higher-powered induction technology that can charge a smartphone battery completely in around two hours.

Chargers are usually categorized by wattage, with 5W and 10W being the most prevalent. They can also be classified according to their output amperage, with 1A at 5V wireless chargers being equivalent to a typical 1A USB cable charger (as most commonly found with iPhone 7).
