Mobile phone and PS4 from Germany to Turkey by plane?

I live in Germany and fly to Turkey to study and I want to bring a cell phone from Germany to mine from Turkey and a PS4 for myself. I'm flying from Germany directly to Turkey by plane.

My question is is it allowed to bring a new cell phone and a Playstation in the suitcase?

Yes, but mobile phones are best for hand luggage or where you can reach us quickly.

It is allowed, but there may be import duties (the cell phone should apparently remain in Turkey).

Here the regulations differ from airline to airline. The focus here is on device batteries.

So I would ask the airline directly what is allowed and what is not. Some airlines only allow lithium-ion batteries to be carried in hand luggage, others up to a certain capacity also in checked luggage.

In principle, I would not put a Playstation in my checked baggage. If you can see how the suitcases are partially transported, it should otherwise be extremely well packed.

No, as far as I know, this is not allowed.

According to EASA law, it is forbidden to transport batteries in a suitcase. In addition, many airlines have a ban on batteries in the suitcase.

I wouldn't put the two devices in the case anyway, because firstly it could get lost, secondly, it is not always handled so gently and thirdly because they are not allowed.
