How does wireless charging transfer power to devices?

Wireless charging uses electricity to send power from one place to another without wires.

Imagine you have a toy car that needs batteries to move. Usually, you take out the old batteries and put in new ones. But with wireless charging, it’s like having a special mat on the floor, when your toy car is on the mat, it gets power automatically, just like magic, but not actually magic.

Think of it like a game of catch. The charging pad throws electricity to the device, and the device catches it. This happens through something called electromagnetic induction, a fancy way of saying “electricity moves from one object to another using invisible waves.”

Inside your phone or watch, there’s a tiny coil that acts like an antenna. When you put it on the charging pad, both coils start working together, and electricity flows in, just like how your toy car gets power without touching any wires.

It's kind of like having a special playground where your toys don’t need batteries, they get energy from the ground when they stand on it. No more taking out batteries or fiddling with cords! Just place it on the mat, and it starts working again.
