No relation to what this specific extension cord advertises. The safety of it kept failing and I had to take it to an electrician to see what the problem was. This one is not a 2.5mm² but a 1.5mm². It seems like whoever manufactures it gets whatever certification they want.

First of all, it has a very good price and so far, from the time I have been using it, it has not presented any problems...

Purchased for charging an electric vehicle in exceptional cases. In case of overheating, it automatically trips the internal safety and has a reset button. For its price, it is a fair choice.

It smells good, thick good quality cable, it has a grounding pin in every position. I haven't seen this in a power strip since the last century
