Learned something new here, great list !! Opened my eyes to what I
already knew, and yup, it makes sense.

Keep in mind a linear wall wart will offer transformation to the lower voltage
from a specific voltage input: think transformer winding ratio.
If it’s 110/115 VAC in and 12 V out, you’ve landed a transformer/based linear
power supply.
If you are offered a wide range of voltage in, say 110-240 VAC and 12 V out you
have a switching power supply.
The only exception I have seen is on travel adapters where there is a specific
input voltage selector switch, changing the taps on the primary transformer.
Hope this helps.
And do read K9YC’s writings on the subject. He’s spot-on in his observations
and recommendations.

If you read the questions and answers of the amazon page for the item you sent, you will notice the seller has posted a link to the 12v
version to someone who was asking for a 12v one. Here is the 12v version:
https://www.amazon.com/dp/B073F51QPY?m=A2G2V645G57K3Y&ref_=v_sp_detail_page&th=1 However, I need to say, I only copied and pasted
the link from the page you posted below. I have no experience using any of the mentioned products and can't recommend any of them. Aly

radio and am not pleased. I would like to replace all switching power supplies with the non-switching kind, everywhere in my house. I found
this 5V one:

It states “regulated” and not “switching”. Also, I can see a transformer on one of the pictures. I am looking
for a 12 V one. Anyone have recommendations? Thanks, Andy KU7T Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for
