I sure would not feed anything close to 7 1/2 V at 4 A into this thing… I’m sure it would kill it. Having said that, even with an input closer to half that, you still get a good long bright spark, and a wicked loud snap. You could probably get usable output by powering it with no more than a USB rechargeable power supply. Running one output through a large diameter needle and aimed at a little aluminum grid connected to the other output, about an Inch and a half away, I-got a nice flow of negative ions that I could feel with my hand, and the smell was immediately noticeable. I think the best way to get a good gap distance is to get it hooked up and slowly move the grid towards the needle until you can see a nice purple corona at the very tip of the needle. Much easier to do in the dark, obviously. That’s what I use these for, as I have found that it really does make a difference in the air quality, removing stale odors, reducing dust, and I totally agree with the research that has shown that people work better, become less fatigued, and generally have a better mood when there are plenty of negative ions in the room. It just adds a freshness and purity to the air that I find very pleasant. In fact, I think this subject is under researched… I wish someone would do some controlled studies to see if food in your refrigerator in the dark would stay fresher longer, and mold would be held at bay with a combination of negative ions, and a UV light that came on intermittently when the door was closed.
