5pcs High Voltage Generator DC 3V-6V to 400kV 400000V Boost Step-Up Power Module High Voltage Transformer

I picked up this little high‑voltage generator out of pure curiosity — you know, the kind of curiosity that usually ends with someone saying, “Hold my drink, I wanna try something.” Surprisingly, this thing works really well, and even more surprisingly… I did NOT get shocked, which already puts it above half the projects I’ve attempted in my life. It puts out an impressive arc for such a tiny module, and once you power it up, you definitely feel like a mad scientist (minus the smoke and emergency room visit). The build quality is solid, the output is exactly what’s advertised, and it’s perfect for experiments, demonstrations, or just convincing your friends you’ve suddenly become an electrical wizard. If you want something fun, powerful, and capable of making you feel like you’re doing dangerous science while actually staying safe — this is the one. Just keep your fingers where your fingers belong, and you’ll be golden. Would absolutely buy again. Still shock‑free, still proud of it. Great value for the money!

Good working condition

It works great and more voltage input means higher output remember that not sure about if its really 400k tho but everyone who says it breaks well their wrong and probably over did it with voltage. Side note buzz buzz.

i have found that you get better results if you use ac voltage other then dc although the instructions say to use dc power. my personal opinion is that you will get better results with ac voltage . especially if you are running two or more in series. when i say in series in talking about the input power!! this my personal opinion ! have a good day you all
