USB-C Trigger Boards

USB C power supply's are everywhere these days, my house has quite a bad infestation.

It seems they are of more use than I imagined. Using a USB C Trigger Board can turn the charger into quite a handy power supply with higher voltage and power outputs.
This video explains how it works.

A search of USB C chargers revealed some chargers output up to 240W  using the  USB PD 3.1 Extended Power Range (EPR) specification.

Lots of USB C trigger boards are available on eBay.

Thanks Ken,
Like you I have those phone chargers but couldn't use them for 5v for the reasons you describe. The devices you've pointed out will be a solution.
Thanks
John

I have a USB-C Trigger Board on the way; I will let you know how it works out. I'm thinking of making a 6BM8 SE stereo tube amplifier for my computer. The USB-C power supply will give me a legal galvanically isolated connection to the mains. I may design a 20VDC to 275VDC and 12.6VDC power supply myself as I have some control the RF noise generated. It is possible to limit the slew rate swapping efficiency for lower noise, it seems easier to make less noise than to filter it out.
I want to use USB-C supply at 20V 2.25A output.
BTW I purchased a 3D printer (Bambu Lab) and now would not be without one.
