Banggood

i love this thing. i dont know about output but it gives a really good strong spark. i only use it for a few seconds at a time. I glued it on top of a £1.00 powerbank and wired it to a momentary button. It's rechargaeble and the power bank is , of course, still a powerbank. hehe. I bought two. I made a video of the arc :) https://youtu.be/rq41C5FmL1w

I already have made one high voltage teaser from it, for personal protection! It's working perfectly! Power Supply is Power Bank. Working frequency is 2 Hz (every second 2 high voltage punches)! Thanks, "Banggood"! Kind regards, Dean, Republic of Ireland, EU

Powerful and noisy using a fully charged 18650, and even says you can put 2 in series... I'm not trying yet. (Photo reference low battery, a fully charged sounds so much that it even hurts the head)

Ottimo prodotto , pienamente funzionante , da usare con molta attenzione , l'errore può causare seri problemi , una scarica a persone deboli può essere letale , io lo uso per l'accensione di razzi in pre combustione , perfetto!!!

A very good product. With an input voltage of approximately +5V DC, the arcs could reach a length of more than 1.5cm.

I took three. Powered at 5 volts the absorption is 1 ampere. The spark is very strong ! Be careful.

It worked exactly as expected. Very powerful - and loud - sparks even at 2 or 3 volts. Great and cheap!
