Excellent, it is the extension in photo (2).
It is the same as the one in the car.
The (1) that is more common has a difficult and narrow opening and you have to look for it every time.

I'm buying it for the second time even though I haven't been impressed by its quality. The advantage and at the same time the disadvantage is that they designed it (probably) to be compatible with all cars. So its socket is quite wide and it is the only extension that accepts the clip of my car (Hyundai i20 2013) which requires a minimum socket of 2.54 centimeters and I assume it also accepts narrower clips. On the contrary, the clip is narrower in order to fit into narrower sockets, but for this reason, it does not fit perfectly in my car, but it does fit. Because it is short, I bought 2 of them, which I connected together to give the required length, they do not fit perfectly due to the peculiarity I described, neither between them, but they do fit. For my car, however, they are the only ones that have managed to work.
