XIT DC Car Charger w/ BT Earphone & Oxygen Bar

Is this using a high voltage to generate ozone (O3)?

It’s actually a negative ion air purifier.

Which means it also unavoidably generates some ozone. Possibly a lot of it, if it’s cheap and poorly made.

This is possibly more effective than a simple ozone generator and probably a bit safer. But presuming it manages to have any substantial effect at all, I’d still be concerned about concentrations it could achieve in a small space like a car.

This appears to be a failed product that’s being dumped on a number of sites (Zulily, “Tumbledeal”, and here, at least); quite possibly because this is simply a bad idea.
