The Chinese and Japanese sure do love their solid state air freshener units, and this is by far one of the best I've come across yet. It's unusual in having proper lithium battery protection, and the ability to operate continuously on a USB charger.
It's a unit that creates ozone on demand by applying a high voltage between a needle and ring to cause a small plasma discharge that temporarily rearranges oxygen atoms. It uses ionic airflow to carry the resultant ozone into the surrounding area.
The units are available in two versions. A battery version that takes four AA cells and runs for one of three durations when activated, or a USB rechargeable version that will cycle on and off to provide a continuous low level of ozone in timed bursts.
The units are sold for freshening cupboards and fridges and can be found by searching for this keyword string:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

YouTube algorithm served this up a year after publication. I can already hear Homer Simpson saying, "Mmmmm… High voltage Twinkie."
I bought one and it stopped working within a month. The HV supply seems to be working but the electrodes have corroded pretty bad
A new twinkie flavor to try? Yum!
I just bought one of these little units. It certainly gives off decent ozone for its size. I immediately swapped out the 1aH battery (tested 1007) & swapped in a 3100mAh. Will run for ages now.
Thanks for the video @BigClive.
very interesting little circuit, made my own 18650 charger, thank you for that lesson as well
I bought one for my car after you released the video . After a couple of months of continuous use it recently stopped producing ozone. Only a high frequency noise.
I found that both the metal plate with the hole and the metal spike were heavily corroded. I cleaned both with some fine grits sandpaper and now it's working again. Maybe this helps others who encounter similar issues.
Mr. Big Clive, would an ozone-twinkie or one of the other cheap ionic refrigerator fresheners you looked at in other videos be effective in reducing the noxious fumes of a resin 3D printer? They fit neatly inside the printer enclosure. I’m not that concerned about the vapors from my printer but there are many who are more concerned about their health than I am.
Ebay: Ozone Generator!
Me: Putting charcoal inside the fridge 😆
Ozone generators can be dangerous to your health so consider using Ionic air cleaners with HEPA filters instead.
I bought one of these Twinkies w the LiPo cell, I'm thinking of modifying it (grounding the ozone module neg lead) so it runs full-time for a larger room.
i got one of these for my little mini fridge that always stinked of coffee (i quite like making iced coffee). after a day of it being in there it no longer smells! Result!
Fantastic little beasty
I bought two of these off ebay. The 1000mah version. I opened one to replace the 1AH battery with a 2.6AH battery I harvested out of some dead gear. Your concern about them stuffing the wires is very valid; the red wire was pinched between the HV spike and the module. Theres a visible crease in the insulation. It has also occured to me this board would be good to use for running anything you can think of on a regular time interval with a battery charging circuit.
If the circuits ever fail, they make a good carry case so your twinkie doesn't get squished in your pocket.
you have gathered quite a collection :D. Between this and the triangular one which would you say is the more powerful one. Also do you think they would work in a car (maybe if I leave them for longer)
I ordered the rechargeable one. Thanks for the heads up on what needs to be tweaked.
They also seem to be selling a rechargeable 2000 mah version now. Do reccomend that one over the alkaline and 1000mah model?
