It's an actual converter, here's the link: https://www.amazon.fr/dp/B09H6G8MS7?psc=1&ref=ppx_yo2ov_dt_b_product_details

I bought a powered radioshack splitter recently to replace my unpowered ones, i live in Europe so I obviously had to buy an adapter/voltage converter, except nothing is happening. And both have no indication whatsoever to indicate that it's on.
If someone who knows what's happening can help me cause this is getting on my nerves.
