## Overview

The DEVMO 5PCS DC 3V-6V to 400kV Boost Step-up Power Module is a high-voltage generator designed to convert low input voltages into an impressive 400,000 volts. With a user-friendly wiring system and safety features, this module is ideal for DIY enthusiasts and professionals looking to experiment with high-voltage applications.

## Description

description please notice:  the high-voltage module should avoid the use of electricity in high voltage no-load . (Power must be adjusted to a suitable distance to the high-voltage output line , battery capacity is proportional to the distance and the use of the high-pressure arc ( not a voltage as high as possible , you must provide enough current ) . Experimental test of the arc distance from short to long , Do not exceed the maximum arc distance electricity, energy can not be released due to high pressure , can easily damage the module. )  Work: intermittent , continuous work does not allow more than 1 minute and the output side does not allow shorting . Improper voltage and long working hours easily damaged module  Package included:  5pcs

## 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.

    AWESOME SPARKS!!

     Nowhere near 400KV, obviously.  The description suggests a maximum 20mm spark gap which indictates more like 60KV but I wouldn't try it, personally. Regardless, these things rock!Having done some testing, I don't suggest over-driving these units. They push hard enough at 6V and won't survive being abused. That said, here are the data I've collected from a single randomly selected unit (1 of 5)3V > 1.9KV4V > 3.3KV5V > 5.5KV6V > 7.0KV7V > 8.3KV8V > 9.7KV9V > 11.1KV10V > 12.3KVIn my opinion these units are best driven at 5V for an 1100x increase to 5.5KV as more input power, even 6V, hardly increases the multiplication factor and dramatically increases the stress on the components even producing a high pitched squeal that would go unheard during normal use as the sparks are LOUD, and likely go unrecognized until the unit fails.Overall, I love these little monsters and highly recommend them of you like inexpensive fun! Just be safe, don't abuse them and temper your expectations. 400KV would jump over 5" easily and my gap is only 3/8" in the video. Still, super fun :)

     I bought these to beef up my electric insect racket. I got tired of wasps, yellow jackets, and hornets not dying on contact. Referencing the video, this is definitely no longer an issue. Highly recommend.

    Not sure if they are actually 400000V but they sure do hurt
  

*by A***S on Reviewed in Canada on 18 December 2023*

I made a pretty sweet lightning finger device out of 3 of these run in parallel and it arced through my protective glove and shocked me worse than walking in on my girlfriend and my upstairs neighbor.
