JacobsParts USB C PD DC Voltage Trigger Test Module 9V 12V 20V Adjustable Power 5A 100W E-Mark Type-C

This does not come in a pretty case or keep you from frying your stuff. That said, it does exactly what it says it does and does it really well. There are two buttons for voltage up and voltage down. Like the description says, it does the negotiation for voltage for you from the power supply. So if you're used to plugging your USB-C phone into that neat little Macbook power puck and it's set to 20v, you will most likely see smoke from your shiny smartphone. I would recommend getting a power tester similar to ASIN B08N3JYDMC to make sure it's putting out what you actually want. A nice touch is that the USB-B connector seems to always put out the correct 5v, regardless of that the USB-C is set to. The buttons can be used to 'lock' the voltage if desired to avoid an accidental change. Instructions are on the back of the unit. One last note is that it is sensitive to which way the USB cord is plugged in. It's actually missing two power pins, which is set by spec, so if it dosent seem to work, flip the cord around.

This review is for the LX-PD01-V3.1 trigger. I purchased both, LX-QC03-V2 and LX-PD01-V3.1 triggers from JacobsParts. Both triggers work perfectly. With both triggers, you can control any modern charger. The PD trigger had a bad solder job (see attached video) two of the pins on the male usb-c were bridged, luckily I saw this before using and used my iron to fix it. I used the AOHi 65w Magcube for testing. The PD trigger was able to get the charger up to 20V mode, although the QC trigger stopped at 12V, because QC uses the data lines to communicate mode, we can use a voltmeter to verify the trigger is doing it’s job. The output is dependent on the charger and example why it’s good to get both triggers.

I got it about an hour ago and was able to test all its functionality other than the presence of the E-Marker chip since I don't have a tester for it. Nor do I have a 100W load. Everything works as described though I don't know what a permanent key lock is supposed to do. It remembers the last voltage that was set with the buttons even if you connect and reconnect. It wants to see a pulldown resistor on the USB-C female connector to start energy flow there but will enable energy flow to the USB-A connector so it must have a pulldown resistor on the USB-C male side. This was the main reason for me to buy this decoy because I want to be able to charge my LiIon car jump starter from a USB PD charging block And, unlike what Michael observed and stated in his May 12 2021 post, I observed that the USB-A connector follows the voltage selected for USB-C rather than remaining at 5V. Now to find a decoy that implements PPS!

I use this to test USB C PD chargers at the various voltage levels using an electronic load to confirm rated PD voltage and amperage rates. It works very well. Simple two button control to change the voltages. I soldered on a couple headers pins to run jumpers to my electronic load. Make sure you use heavy enough wire for the amperage you will be drawing. I used some high gauge wire (thin) and it melted but no problems with is tester handling all the loads.

I bought this somewhat impulse buy to test PD ports on my portable power banks. I was rather surprised to see it work so easily. Plug it in and it negotiates the voltage to the last setting. The two rectangular tactile switches select up and down for voltages and some other functions printed on the circuit board that I didn't test. My USB load tester can only go to 25W so I added 20awg wires and an PP15 connector for my larger load tester. I then coated with urethane conformal coating and liquid pvc to protect the contacts and parts from my fingers. I would prefer better protection, but this low cost device. It handled 100W (20V at 5A) without too much voltage loss. Overall, recommended for testing USB-C power delivery ports.
