You clearly didn't bother looking at the links and have less than zero idea about importing and reselling in this or likely any other country outside your own so stop making claims to the contrary based on your brain instead of the facts. Cause a house to burn down or electrocute someone with non confirming equipment and see how you go. Importing non conforming/tested power supplies into Oz is NOT illegal reselling them is. Physical testing is part of that so again to be clear you are WRONG re Mouser, E14, Digiokey et al and conformance.

Mouser is a web gateway and is a US based retailer with an office in Hong Kong I am not aware of a local presence. Again you seem to be trying to make believe different to prove your non argument.

As this is now well OT feel free to keep getting your knickers in a bunch with others who dare cross your lack of knowledge and imagination.  :palm:

Please see this thread: https://www.eevblog.com/forum/buysellwanted/acdc-adapters-12v-4-16a-50w-earth-referenced/
Although they may be overkill for your purpose (12V 50W output), they are decent quality.

Buy a used adapter for a quality name brand item on eBay...  they are often very little money, and you will get a nice unit.

I have just recently upgraded my under cabinet lighting.  For each cabinet, I used a little PIC controller, with a 433Mhz receiver. I used 12V supply for both the LED lights and with a 5v regulator for the digital parts.  I have tested quite a bit of supplies, both from Ebay and Amazon. I mostly just buy the 12V power bricks and just remove the cover and use the bare parts.  I also bought, on Ebay the power brick parts, with the plastic cover.  Most of the problem I had was that they could not supply the claimed current.  I bought all 5A, 12V.  A couple of them can only supply about 2.5A.   One, had a bad filter cap that I had to replace.  Aside from that, they all seems to be OK.   None of them broke.  I'm now running these 24/4 for about two weeks.  I'll have to see how long they'll last.

+1, buy from reputable suppliers please...

I once brought a spare laptop adapter from ebay (for the first time) and thought it would be ok. Exploded in my hands as soon as I plugged it in (I was at Uni, it tripped half the office)  :--
Luckily my laptop also made it out unscathed !!!

Emailed Asus about it and reported the suppliers and then brought an official spare adapter from them was quite expensive, but I was just happy I was safe and didnt cause any irreversible damage.

I've been using some of these https://www.aliexpress.com/item/32905696401.html (various models at different voltages) for a while and they appear to work stable over months of operation.
