How to Make a Simple Wireless Charging

Inductive charging (also known as wireless charging) uses an electromagnetic field to transfer energy between two objects through electromagnetic induction. ... Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device.

Step 1: Video

see this video if you like it you can make it

Step 2: Make a Simple Wireless Charging

To make a sample wireless Charging we need

1- NPN transformer (2N2220A)

2- 1Kohm resistor ()

3- copper wire

4- LED

5- 1.5v battery

Step 3: Coils

make a coil two coils

the first coil make 15 Turns and make a center tap then make more 15 Turns

the second Coil make 30 Turns

Step 4: Circuit

draw the circuit such as the photo

Step 5: Other

for test connect an LDE to the secondary coil and test it

Hello, could you please tell me why are we using a transistor? Could you give us more detail about the logic of the circuit?

When making a coil what am I supposed to tie the wire to?(type of metal)

It's not charging ... is this really working

Nice design !

Classical. This build is not efficient at all but fun to experiment. Simply take care that there's an alternative current on the secondary coil.

dear I said its is only a simple . before i build a DC to DC converter it the best efficiency for a make a good wireless charging.
In secondary coil if you use a diode and capacitor you can make a DC
