    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)

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

    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 :)

    Superb and astonishing 400Kv boost circuit. you can generate very loud and powerful sparks. USE WITH PROTECTIVE LENS AND INSULATING GLOVES TAKING PROPER PRECAUTIONS because a so high voltage could be dangerous and could kill you. Exciting for high voltage experiments Circuito boost 400Kv superbo e sorprendente. puoi generare scintille molto forti e potenti. UTILIZZARE CON LENTI PROTETTIVE E GUANTI ISOLANTI PRENDENDO LE PRECAUZIONI CORRETTE perché una tensione così elevata potrebbe essere pericolosa e potrebbe ucciderti. Emozionante per esperimenti ad alta tensione
