Ah, EU-only. That explains why I've never heard of it, among other things.

Well... if you look behind anything that plugs into a wall socket you will see that it has ( among many other things) a CE mark. Even things in the USofA have a CE mark.

If your new product cannot have its CE mark for whatever reason, you will not have the approbations to sell in the USA either.

What the CRA will do, is if you do not have a "CRA" compliant product, you will not have the CE mark. Which means you will not (with very high probability) have the other marks needed to sell outside Europe.

Maybe then you can just sell to your close family members who like you, but good luck if you get caught and it can be proven that your shitty device caused a fire ...
