Made in China is Made in China.
Well there is a lot more nuance to this.
I use Meanwell on a professional level.
With companies like Meanwell etc, you know for sure they went through the trouble to pass all kinds of EMI and safety regulations.
They are way to big of a company to be able to fly under the radar, but also put their credibility at risk.
Because Meanwell PSU's are being used in A LOT of products and companies.
Unless you really can't get anything else in your region, but for the small difference in price, I wouldn't recommend any unknown Chinese brands.
The very vast majority I have tested don't even pass basic safety regulations (clearance and creepage), EMI is even worse.
I also had way to many just quite literally dying out of the blue, or even "exploding".
Running the risk of frying the rest of the electronics as well.
I personally have only bad experience with unknown Ali PSU's and I have tested a whole lot PSU's in my life.
If you're in Europe, either just buy at TME or Elpro.org, I think Mouser is also possible for private consumers these days?
In the US you can use Mouser anyway as far as I know.
Btw, a problem a lot of these PSU's have is that they go into some "green" more efficient mode at low loads.
This will not only create a lot of noise, but this can also create a lot of other issues.
19V is not very common unfortunately, and Meanwell still seems to be a bit behind with stock (we also have issues with this at my job).
At TME there are still a few in stock;
