Induction heating of liquid in a steel pan occurs much faster than simply placing it on a fire or electric stove. This principle can be used to make a cordless kettle. This device will allow you to brew tea, coffee or other drink in a minute.

The process of making an induction heater for a mug with your own hands
To assemble such a kettle with your own hands, you need to etch the proposed circuit onto the printed circuit board.
Components of the specified denomination are soldered into it.
Field effect transistors are installed in miniature radiators.
Next, select a small steel glass. Enameled wire is wound around it. The ends of the coil are soldered to the board.
Then you need to make a holder for the kettle body from a dielectric material. It is best to print it on a 3D printer. It should include a handle, places for batteries, boards with components and a switch.
The parts are placed into the housing and soldered.
The coil must be insulated from the inside so that it does not directly touch the glass.
As a result, 12 V power is supplied to the circuit through the switch. Now, when you press it, induction heating of the glass and, accordingly, the liquid in it will occur.
