DollaTekPD/QC/AFC fast charge decoy trigger support 5V 9V 12V 15V 20V fixed voltage output Type-C USB For Phone Solar Fast Quick Charger

Only down side is I needed to get the film off the top of the switch. It’s only there to help the machine that puts it on the PCB lift it with its sucker. I think some reviews left it on and struggled to operate the switches.Managed to get all the voltages I need from my Ugreen power brick & Asus monitor. Planning to use it on my home project to get the voltage current I need.

Electrically OK, but could be more compact. Switch labelling is misleading on the board: an "On" switch is 0 in the truth table, not 1. Check the voltage before connecting anything fussy !

switch logic as supplied - 'on' = 1output voltages programmed on generic usbC000 - 12001 - 12010 - 9011 - 9100 - 20101 - 15110 - 5111 - 5on Dell type 3 terminal with 7.5mm to usbC adapter000 - 9001 - 9010 - 9011 - 9100 - 20101 - 9110 - 5111 - 5

Works fine, was able to get 5V, 9V, 12V, 15V and 20V from the output depending on the switch positions.Bear in mind this needs a USB-C PD power source that can provide these voltages, it is not a converter and if you only provide 5V then it is only going to output 5V.My only complaint is the switches are a bit too small and feel like that may break if changed too often.

Output is only 5V. Maybe DIP switch is broken or its just Chinese crap.

Can output all voltages up to 20V so long as the PD source you use is also 20V. That said, i think the DIP switches are inverted, so where it says on is actually off. Or im reading it wrong. Either way, with a bit of trial and error it works perfectly.

After a while with the multimeter I finally figured out the 3 switch positions to get my desired voltage. It was nothing like the combination in the instructions though. It's reasonable. I haven't tested it for very long.

Didnt notice this at first but for those who cant get down to 5v… Down position is 1. Up is 0. So 5v looks like this.
