Featuring an e-Mark chip to unlock high current modes, LED voltage indicators, and voltage lock functions, it’s designed for tech-savvy users who demand precise power control and reliable testing of USB-C PD chargers and power banks. ## Description Instructions:• USB-C power supply must support the PD protocol• Basic operation: Connect the module to USB-C PD power supply. The LED indicates the current voltage. If no LED is illuminated then it is currently at 5V. While holding S+ press S- to unlock the board. Press S+ to increase voltage. Press S- to decrease voltage.• Reset to 5V: Press and hold the S- button while connecting the module to the power supply• Quick key unlock: After powering on, while holding S+, quick press S-• Quick key lock: After powering on, while holding S-, quick press S+• Permanent Key Lock: Press and hold the S+ button while connecting the module to the power supply. Press S+ or S- to enable or disable the key lock. If the key lock is enabled, then the voltage cannot be changed until it is unlocked.• Test Mode: Press and hold S- and S+ simultaneously while connecting the module to the power supply. The output voltage will automatically cycle between all supported voltages. Review: 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. Review: 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. ## Features - Power all kinds of electronic devices with USB-C PD chargers and power banks • Test power supply capabilities - Performs real PD power negotiation • Supports up to 5A / 100W • Has the e-Mark chip necessary to unlock 5A output on 100W power supplies - Trigger 5V, 9V, 12V, 15V, or 20V output (not all USB-C power supplies support all voltages) • The module just performs the PD negotiation and passes the output - LED voltage indicators • Retains setting after power loss - Power supply must be connected to the male end of the module ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08NWG54LP | | Best Sellers Rank | #174,133 in Electronics ( See Top 100 in Electronics ) #1,665 in International Power Adapters | | Brand Name | JacobsParts | | Color | Black | | Customer Reviews | 4.5 4.5 out of 5 stars (49) | | Manufacturer | JacobsParts | | Maximum Operating Voltage | 20 Volts | | Measurement Type | Voltmeter | | Minimum Operating Voltage | 12 Volts | | Model | POWTRIG-E | | Part Number | POWTRIG-E | | Power Source | Dc Power Supply | | Specification Met | e-Mark | | Style Name | Electronic | | UPC | 845832031903 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** JacobsParts - **Colour:** Black - **Min.

I've only used it for the selectable voltage output, and that's the typical use. **Q: is there any mode to program custom voltage like 14.2V ?** A: I don't know about that part, but you can build the power supply and the voltage range. **Q: When plugged into lenovo m90n (mini desktop), this flashes and stops working. Any help? Unit works with other sources.** A: Since the PD works with other sources, the problem has to be with the M90m. Try a different port on the computer. **Q: Is this usb-C directional? I was about to return it because it didn't work, but then discovered that when I flipped over, it did?** A: The specification IS bidirectional. To take advantage of that, any cables you use, and any adapters, and any devices you plug into it will also need to be bidirectional. Another thing you might like to know, is your cable(s) must also be rated for the POWER you want to draw from your source. Power may be rated in Watts (usually) or in Amperes (Amps). Amps times Volts = Watts. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***R on 13 May 2021* This does not come in a pretty case or keep you from frying your stuff.

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! ## Frequently Bought Together - JacobsParts USB C PD DC Voltage Trigger Test Module 9V 12V 20V Adjustable Power 5A 100W E-Mark Type-C - DROK USB Load Tester, Electronic Load Test Resistor Module 25W LD25 USB and Type C Interface Discharge Adjustable Constant Current 0.25A-4A Intelligent Temperature Control with Cooling Fan - Treedix USB Cable Tester Board USB Cable Checker Data Wire with Acrylic Case Charging Test Data Line Type-C Micro Type A Type B --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/388022954-jacobsparts-usb-c-pd-dc-voltage-trigger-test-module-9v](https://www.desertcart.in/products/388022954-jacobsparts-usb-c-pd-dc-voltage-trigger-test-module-9v) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-04-28*
