5pcs High Voltage Generator DC 6-12V to 1000kV Boost Step-Up Inverter Arc Pulse Generator Power Module High Voltage Transformer

Whatever you're building if you need one of these I recommend it thank you.

I purchased a 5 pack of these dynamos. I attached a nine volt battery to the black and red (line) leads, but there was no current at the other (load) end. I tested all five with two batteries. Then I tested all 5 with a multi meter and found no flow of electricity from one side of the dynamo to the other. There was however, continuity from the black lead to the red lead. This was true for every voltage generator. I returned that first five and quickly received another five. All of these new ones tested identically to the previous five. It looks to me as if they have a defective manufacturing process and no quality control.I would like to retract this review. I used a fresh battery and ended up shocking myself.

So me and a buddy are enrolled in an electrician course, and we might👀 have used these and some 9v batteries to build a taser (don’t worry we knew what we were doing). I will say that these things are really strong, we ran WAY too much current through them and they’re still working fine. It was a great project, super fun, and honestly made us jump when we first started it up.

Mini transformers 1million volts of electricity each kilovolt is equivalent to 1000 volts times 1000 is 1,000,000 volts of electrical concurrent energy satisfactory guranteed perfect for my diy hobbies and engineer crafts thanks guys will be back to purchase in bulk amounts

all of mine worked no idea what kind of amusement i plan on using the rest for

The media could not be loaded. These are a lot of fun. This 9 V battery is almost dead yet look how much voltage this little module produces holding your hand fun

The media could not be loaded. OK here's the thing. After testing these things for a while I can say that their lifespan depends on how they are used. I'm sure as long as you aren't being to hard on them they will be fine. Also another thing the transformers likely aren't what are burning out on your tazers. Tact switches which are what most people use are only rated for around 50ma or so. When you are pushing such high amperage it's really easy to fry them. My first taser I made I fried the switch. I replaced it shortly after and it worked perfectly fine. Overall really good product I definitely recommend

The first one fried after half a dozen arcs. Hopefully number two does better!
