How long is the body of this transformer?

The product never arrived. Though, I got a refund for this transaction. For the first time I was very disappointed with Amazon. I had ordered twice and waited over 30 days each time. The product never arrived.

Direct Current output, alternating current input

Can I see schematic? Or to at least tell me if its a H.F inverter or is output rectified? Can it be hooked directly to the primary of Tesla coil?

I hooked mine directly to, two 123 batteries in series, 6 volt and got some nice spark out of them. I had one bad one out of the bunch, but for the price I wrote that one off.

Great bug zapper

These are simply amazing for the price. I'm building my own wasp killer that I mount on a pole and trigger it from a safe distance. I'm one of those "prove it" guys and yes it knocked me right on my butt!

Very durable, delivers very high voltage

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.

Fits harbor freight electric flyswatters

Put these in harbor freight electric flyswatters and now they're much more powerful. They make it arc between the screens like a taser. Much more enjoyable bug swatting experience

Zap zap fried...

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

Complete failure...My bad. my batteries were old and not delivering enough power

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.

Haha

Bought these when drunk... Both worked though! Fun stuff, lots of goofy potential. 1.7v is pretty uncomfortable, burns and muscles in the arm want to lock up. I plan to build at 3.4v and I am not looking forwards to testing it lmao
