Hey friends, Happy Wednesday!
Last week, I went on a mandatory yearly shopping to Stonestown galleria. And went on a hike with a friend, in San Francisco.
I’m including an extended summary of how a gadget works in my newsletter, from which you can understand the essence in less than 3 minutes.
Let’s look at how Wireless charging works this week. I aim to write my newsletter issues in a way one can follow them while traveling on a bus, having a coffee, waiting for your food, etc. Let's jump in!
I’m sharing a cool fact about gadgets every day on Twitter. And here is one of them for you!

Introduction
Wireless charging is based on the principle of transferring electrical energy from a power source to a device utilizing electromagnetic fields to transmit power wirelessly. This is made possible through a combination of two essential components: a transmitter (or charging pad) and a receiver (embedded in the device being charged).
Principle
According to Faraday’s law of electromagnetic induction, an electric current is induced in a conductor when it is exposed to a changing magnetic field. This principle forms the basis of how wireless charging operates.
Working
Limitations
The power transfer efficiency is generally lower compared to traditional wired charging, resulting in slightly slower charging times. The range between the charging pad and the device is also limited, requiring close proximity for effective power transfer.
And this is how wireless charging works. Thank you for reading!
Have a nice rest of the week, and take care!
Until next Wednesday,
