I would change it too, but it may contain a sealed in fuse, ie if the built-in fuse goes pop, the unit is thrown away, not repaired, ever.

Can you open the plug up to see what's inside please? If it doesn't contain a fuse, the whole power-supply is suspect. Is it from the 'too-cheap' family! Is it CE marked?

What fun!

If you bought that from a UK supplier then trading standards should be advised. It certainly does not look to comply with current electrical standards.

The plug is the most obvious breach of CE regulations and should be changed. My concern though is whether what is inside the enclosure is safe to use (I'm being serious). We have no idea what you intend to use it for but potentially under fault or failure conditions there is always the possibility that mains voltage could be present on the output connector.

It's a BangGood special! I'd bin it…

It may be CE marked but there is a subtle difference in letter spacing between the EU mark and the Chinese Engineered mark.

They are lethal, cut it of and fit a proper plug with the corrrect fuse. I have had a few of these turn up on devices like hard drive enclosures and other computing related equipment, they are all in the bin, it does raise doubts about the rest of the engineering of the equipment but as they are attended devices and as long as they work I don’t worry too much. I would have second thoughts about a device that would be powered for long periods or permanently on and unattended. People will slag off China but remember they also manufacture a lot of top quality electronic equipment but usually with a top brand name as well.

If you must use it, don’t leave it plugged in and switched on at the socket – it is powered all the time, despite it having a switched potentiometer – it only switches the output (and the display).

Too many transformer wall warts have spontaneously burst into flames. What is the transformer rating, if of that type (it must be shown, by law)? Lower grades are not allowed to be sold, these days, I believe, as transformer losses can be considerable.

It isn't the plug that is a threat unless you expect it to b used by children or halfwits and you could easily clue on a plastic disc with 3 holes in it if you are really worried. The danger as mentioned above will be fire especially as it is advertised as 70W . It is switched mode so no transformer and probably fully potted inside which actually helps heat dissipation. Of course there are lots of non CE items being imported as long as you allow advertising and direct shipping of electrical goods. What do you expect – trading standards to open every package arriving from China?

Doesn't CE stand for China Export?

I have never understood the British love of fused plugs: most of the world seems to be happy with unfused plugs. None of the electrical equipment that I bought when I lived in Switzerland has a fused plug, for example.

Other than the regulatory requirement here (and after all it does sound like a good idea), can anyone explain why Britain and the colonies have this different plug philosophy?

The earth pin on that plug is shrouded which is another no-no and instant giveaway of a non-conforming plug.
