Welcome to the forum.

Key word in your post is CHARGER.

You need a power supply and not a charger - save yourself a lot of future hard to track down issues and follow the link provided above (been there - had the problems - bought the power supply)...

There is nothing to charge up on a Raspberry Pi SBC !!!

Thanks for the reply of course I meant power supply (my fault).
But would I power the raspberry pi with an ps4 controller charger (it is a micro usb) if it was inserted in a pc or would I need to get the official power supply?

(I am new to English and most google translate so sorry if I missed something)

I would get the "official" power supply.
It is cheap to buy, is good quality, and works perfectly - probably because it was designed specifically for the job.

You can't power the pi from a USB port on a PC using your charger cable, as the USB port on the PC will only supply 500mA which is not enough to power a pi3B+, the answer has already been supplied get the official power supply.

Just for your information... These forums have an extensive list of sub-forums in various non-English languages. The odds are very good that there is one for your native language.

Battery chargers are not required to maintain precise voltage regulation, because that is not needed for charging batteries (in fact, some charging algorithms require voltage changes during charging). Because of that, many will not maintain a stable 5V under load.

I used to have a "5V/2.4A" phone charger that dropped well below 5V at only a 1A load. It worked fine for charging my phone and tablet, but it was a lousy Raspberry Pi power supply. In addition, the battery in a PS4 controller is likely quite small, and I can't imagine the charger would output anywhere near the 3A recommended for powering a Raspberry Pi 4B.

So using your PS4 controller charger is not recommended, and would probably not work well.

The official Raspberry Pi4 power supply is affordable, and of course, works great.
