Ideal for educational demonstrations and experimental setups, it features a pulse current output with a strict 1-minute usage limit to prevent damage. With precise discharge spacing and easy wiring, this module delivers powerful sparks safely when handled responsibly. ## Description Size：24x22x63mm Input voltage: DC 3V to 6V Input current: 2A - 5A High pressure type: the type of pulse current Output voltage: 400000V(Please pay attention to safety) High pressure discharge distance between: 10mm - 20mm The output high voltage wire length: 100mm Input power cord length: 100mm (the red line is positive) Review: great for teaching - yes they work very well. Review: These ROCK!!! - Major Warning!!! Treat these modules with respect. They will set you on your you know what if you aren't very careful. A *brief* touch to a 9 volt battery will pop out an inch long spark and a loud snap. They are NOT rated for 9 volts, and operating in that range will destroy them quickly. The dielectric properties of insulation are absolute. Exceed it, and it perforates. Period. I marked the module I tested, and plan to discard it. They are also not rated for high current, so include a (high voltage) resistor in your final circuit. Remember that at 400 kilovolts, it only takes a current of 0.0025 milliamps to produce 1 watt of current. And that would probably be about the limit to these, unless someone wants to do some destructive testing. Quarter watt resistors aren't going to do the job, which is why I said HIGH VOLTAGE resistors. If you don't run them continuously, and don't exceed the input voltage constraints, great. Just don't complain when they stop working. ## Features - ★Output voltage: 400000 v(Please pay attention to safety) - ★High pressure type: the type of pulse current - ★input voltage: DC 3 V to 6 V,Input current: 2 A - 5 A - ★High pressure discharge distance between: 10 mm - 20 mm.To avoid burning, use the time limit for 1 minute. - ★Package Includes:1pcs 400000V Boost Step-up Power Module. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07S712WKL | | Best Sellers Rank | #167,129 in Computers ( See Top 100 in Computers ) #31 in Modem Cables | | Brand | DEVMO | | Color | Black | | Colour | Black | | Customer Reviews | 4.3 out of 5 stars 424 Reviews | | Input Voltage | 6 Volts | | Input voltage | 6 Volts | | Item Weight | 0.07 Kilograms | | Item weight | 0.07 Kilograms | | Manufacturer | DEVMO | | Model Number | 2c749d5a-be5d-4ce6-9ae5-51ad72222c70 | | Output Voltage | 400000 Volts | | Output voltage | 400000 Volts | | Plug Type | Type A | | Plug type | Type A | | UPC | 016071890013 | ## Product Details - **Brand:** DEVMO - **Colour:** Black - **Item weight:** 0.07 Kilograms - **Input voltage:** 6 Volts - **Output voltage:** 4E+5 Volts ## Images ![DEVMO DC 3V-6V to 400kV 400000V Boost Step-up Power Module High-Voltage Generator - Image 1](https://m.media-amazon.com/images/I/71wP2xR5aIL.jpg) ![DEVMO DC 3V-6V to 400kV 400000V Boost Step-up Power Module High-Voltage Generator - Image 2](https://m.media-amazon.com/images/I/71unZwPDatL.jpg) ![DEVMO DC 3V-6V to 400kV 400000V Boost Step-up Power Module High-Voltage Generator - Image 3](https://m.media-amazon.com/images/I/61zas70zEhL.jpg) ## Questions & Answers **Q: Is there a good way to extend the output leads? I need them to be longer than they currently are.** A: Strip the outer end of the wire about 5mm and solder on longer wires. Then heatshrink the joined part for insulation. **Q: is the output a ground and a high positive or high negative, or is the output a high negative and positive?** A: i beleive it is 3 volts dc to an inverter with high volts AC out not DC out **Q: Is the output voltage ac or dc?** A: AC. Probably around 40 000V peak to peak. Low amps. **Q: How can it be 400kv if the output leads are only 1 inch apart and use ordinary 250v insulation? if it was more than 25kv it would just arc the leads** A: Well, first of all, that's not ordinary insulation. I didn't test it, but it looks like kynar. The maker used good output wiring. I'm not going to back his claim of 400KV, because I personally have not taken one of the units into my lab and measured it, but I know a good bit about HV. Don't assume that the breakdown characteristics of air are linear. They're not. Under normal kitchen table conditions, you can draw 4 inch sparks from a 20kv source. Once a plasma conduction path is established, it is self-sustaining as long as the current keeps it hot. ## Customer Reviews ### ⭐⭐⭐⭐⭐ great for teaching *by A***R on 28 June 2025* yes they work very well. ### ⭐⭐⭐⭐⭐ These ROCK!!! *by D***T on 18 January 2022* Major Warning!!!
