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 ### ⭐⭐⭐⭐⭐ Seems good *by A***R on Reviewed in the United States on 11 November 2024* Just testing the first one seems to be working well. 3V in pulled ~9 watts (~2 amps), I put a 5 ohm 10 watt resistor on it so it hopefully won't cook itself. ### ⭐⭐⭐⭐⭐ AWESOME SPARKS!! *by N***E on Reviewed in Canada on 29 September 2023* The media could not be loaded. 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 :) ### ⭐⭐⭐⭐⭐ Amazing *by K***N on Reviewed in Canada on 12 May 2024* They worked perfectly to really make my taser really arch ## Frequently Bought Together - DEVMO DC 3V-6V to 400kV 400000V Boost Step-up Power Module High-Voltage Generator - 9V Battery Connector,10 PCS T-Type 9 Volt Buckle Connector Hard Plastic Shell Used in Student Experiment,or Other Equipment with Battery - WGGE WG-026 10 Pieces and 5 Colors Test Lead Set & Alligator Clips,20.5 inches / 22 AWG Copper Wire.
