Re: Noisy Pi4 - particularly on 2m

They are definitely all not equal. I have one now running a 4B with no under voltage alerts for months.
There are lots of little, cheap, USB voltage and current monitors that are available. Plug your module into it and then from the monitor to the Pi and you can see the voltage and current draw. I use it to check 5V supplies, and some will show 5.2 or 5.24 volts, and some show 5.0, or 4.98. You take what you get. The 5.2 volt outputs work great for all the Raspberry Pi models.
Search on eBay for "Multifunction USB Tester"

Alas they do not do what the Raspberry PI 4B calls for.
So far I’ve not had one go wrong for 5v needs.
i had good results for anything that needs 5v with these black power modules
they can be found with open end wires or with usb connector

Could you please provide a link or two just to give us a clue about what you're talking about specifically ? There are so many devices on Ebay it would be really helpful to narrow it down.
