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

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.

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.

switch logic as supplied - 'on' = 1 output voltages programmed on generic usbC 000 - 12 001 - 12 010 - 9 011 - 9 100 - 20 101 - 15 110 - 5 111 - 5 on Dell type 3 terminal with 7.5mm to usbC adapter 000 - 9 001 - 9 010 - 9 011 - 9 100 - 20 101 - 9 110 - 5 111 - 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.

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.

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 !

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.

Ottimo trigger! Funziona perfettamente con PD, QC e AFC, permette di selezionare facilmente le tensioni da 5V a 20V. Ideale per testare caricabatterie e alimentazioni rapide. Compatto, preciso e davvero comodo per chi smanetta con l’elettronica. Buon acquisto!

As my title says not sure why it gets warm but that's it. All of the combinations you can see on the back work as intended. Just keep in mind the actual voltage might be different depending on charger you use. In my case on some charger all voltages gets output except for 12V because charger doesnt have that option. So what this board does when its on 12V option is that you get lower voltage of that (instead of 12V you get 9V). When set to 15V or other options works as expected. Soo before anyone judges it that it doesnt work, please check your charger's specifications

Ordered two, one works but does not provide 9v. The other one did not turn on at all.

This module is useful in several different situations. Im currently using it with my soldering iron, which is powered by USB-PD but has problems with its built-in PD chip, and thus only take 5V from all PD chargers, so now with this module in between the charger and iron i can get 20V to my soldering iron instead of only 5V. When it comes to the voltage settings according to the writing on the backside of the PCB, the DIP switch is "0" on the side of the Switch that says "ON KE" and is considered "1" on the other side that says "1 2 3", this can be a bit unclear. But always measure the output voltage with a multimeter before connecting the module. I have only used it briefly with peaks up to around 65W, i wouldn't use it for an extended time at 100W though, at least not without active cooling. Will have to see how it holds up in the long run, but so far im satisfied, it does exactly what i want it to do.
