I have been trying to find a non-isolated buck converter (12 Vdc input to 5 Vdc, 2A output) with the CE certification. This is similar to a USB charger that fits in the cigarette lighter of a car but with wires or screw terminals for input/output instead of the USB and cigarette connectors.
I know these converters are very popular and are used in cars/boats, solar, lots of battery powered devices. I don't think it's a coincidence that none of them are CE certified. How are these imported and sold in Europe without the CE marking? Is there an exception for very low DC voltage devices?
