Unfortunately not, because the housings, although they look small, are in each other's way and part of the triple socket is covered in such a way that there is not enough space to connect more devices.
Generally, I advise against buying a PowerLine with 500Mbit/s, because that is money down the drain. Today there are solutions that can do more than double that. With PowerLine it is very important that you start with high speed, because otherwise you won't get much at the other end. That's why I recommend at least PowerLine AV1200 products, such as
Devolo Magic 1 LAN Starter Kit 1-1-2 (1200 Mbit/s)At least you still have a socket on the PowerLine device that you can continue to use.
