3Pcs Type-C QC AFC PD2.0 PD3.0 to DC Fast Charge Decoy Trigger Polling Detector USB-PD Notebook Power Supply Change Board Module Support 5V 9V 12V 15V 20V Fixed Voltage Output

First thing I wanted to do with these is attach it to my NodeMCU board so I can power it and my LED lights for WLED. This actually went pretty well, got it attahed to the board with 5V and just simply made a splitter wire to connect it to both the NodeMCU and the LED connector. I also attached one of them to my soldering fume extractor I made from a 3D printed holder and a old PC case fan I had lying around. This one was a bit more annoying because I was working with small wire but it ended up working out; got it working on 12V. Having the various different voltage modes makes these boards really flexible for various different projects; I just wish it wasn't as expensive (they can be found on other sites for MUCH cheaper, but they take quite a while to arrive and I needed these rather quickly).

Edit: Thank you to Zed for the suggestion that my issue below may be due to using USB-A/USB-C instead of USB-C/USB-C. I am so grateful for your suggestion. After switching to the cable as suggested, it works great! Original Review: I connected this to a power bank which specifies that it can supply 12V at 1.5A, yet when connected to a 1A load (with the dip switches on this board set for 12V), this device stopped supplying power (output reduced to 1V) and remained this way after disconnecting the load - until disconnecting and reconnecting the power to this device. I verified the load device worked as expected with a 1A wall power adapter. Testing with other devices I got the same result but with output reducing to 5v instead of 1v. The listing does not specify a limit on current draw for 12 output.

You often see people give electronics modules poor reviews on Aamzon. This is simply because they have no idea what they are doing. These are great modules.

Decent board.I was able to get 5, 9, 12, 15, and 20 volts from a laptop charger. The cable I used was a 240W usb c 10 foot.I got 12 volts from a power bank that boosts 3.7 volt 18650 lithium ion cells.At 20 volts the ancient (LM?)75L05 linear voltage regulator got very hot without a load. This chip is many scores old. The unmarked chip remained cold. Talk about generic, the 10 pin dual-in-line-package surface-mount chip was completely unmarked except for the pin-1 marker.Starting from 12 volts, the 3-pin chip gets warm with no load. I would recommend using small loads. I haven't tested load size, sorry. Just keep it small, no jackhammers.Nice DIP (dual-in-line-package) switch, needs pointed tool to move.There are 3 connections for positive + and 3 connections for negative -.It is completely flat on bottom.
