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

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.

Nowhere near 1000kv, I ran a test steady on 5volts and I’ve determined that every 200mA, it will deliver 900volts. This is only in my experience and it could vary depending on the transformer because I’ve only tested it on one.

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

Some work some don’t

Don’t be fooled, these give you extra bang for your buck! If you need to reengineer your Webber ignition THESE will absolutely amaze you!

One of five, didn’t work and there was a limit to continuous operation, arcing.

OK I purchased these as I'm a gadget junkie. With a 9 volt battery I was able to get a very loud arc of up to a half inch. Putting the wire ends closer produced a quicker arc while extending them to half inch apart produced an immense impressive slower arc as one would get from a high power stun gun device.Only used one so far to see what they were about with maybe 10 minutes of total on time (but not all at once. Just intermittently) Seem to be impressive enough & stable enough. As with all electronic stun devices that produce an arc I'd advise to not let it arc for more than 5-10 seconds at a time. Great very simple demo item.

It works well but it's fragile. The description says I can input 5 amps but it can only handle 3.5 before it breaks

Ich habe sie mal zum ausprobieren an einen 9V Blockakku angeschlossen, nichts. Dann an ein Netzteil (12V) und habe mich ganz furchtbar erschreckt. Alle Achtung, das knistert ordentlich. Nachdem ich den Blockakku dann frisch geladen hatte, brutzeln die Dinger auch damit schon recht beachtlich. Ich sag mal so 10-15mm zwischen den Ausgangsdrähten überbrückt das dann schon. Da fallen mir bestimmt ein paar lustige Experimente zu ein. Schönes (nicht)Spielzeug.

4 out of 5 worked other 1 just started to smoke and heat up

Wird bei 9 Volt Betrieb sehr warm! Aber Preis Leistung passt
