Well done!

For a start, you've done well. However, using it for a phone isn't the best use case though. You can try ferrite transformers and design from the to achieve size reduction.

My next project will be power bank!

Okay. The cost of charger in the market will let you know if production on a large scale will be feasible.

Good one
I believe it's will not damage my phone, i can't sale phone to buy charger.

Can you make a laptop charger?

I made a laptop powerbank.

It can charge laptop and phones at the same time

I am sure you won't be using a phone if that's what a charger looks like.

I score you zero!

Components used for this project includes
.
1) 240v (9-0-9) transformer
2) 4 Diodes (no unit)
3) 1k/25v capacitor
4) 7805 transistor (regulator)
5) 0.1/25v capacitor
6) light emitting diodes (led)
7) USB port
cool a connection board
.
I first of all connected my four diodes in series, then my 1k/25v capacitor followed by transistor, 0.1/25v capacitor, light emitting diodes, USB port then my 240v transformer on the connection board, I read it with my meter and it gave me exactly 5v.

Can it charge any phone type? Smartphones and iphones?

Very necessary

I have used up to 30 laptop chargers or even more since I started using laptops...the worse na blue mouth charger and more expensive than others

Nna, wazobu!?
Na wetin dey killi ya lappie charger lak dat nah?
Check your voltage (DC) power source...


Even Yahoo boys and forex guys nor suppose dey change chargers lak dat cool

Great job for effort if you are still in secondary school or thereabouts

However as a university student, you need to be thinking outside of the box to truly innovate and solve our energy problems i.e. creating a phone charger that’s totally dependent on renewable energy

Do you have a circuit diagram for this?

You used the transformer to step down the Ac. How many volts did you get after stepping down the voltage?

The diodes were connected to AC to rectify the current. Then a cap. The DC voltage is high at this point.

Did you use the transistor to reduce the voltage. What voltage are you getting at this point?
