Car ozone ionic air freshener teardown.

Teardown of a compact air freshener that plugs into your cars cigarette lighter socket and freshens the air with ozone and ions.

Or just lights up dull blue and does nothing.

The only reason I bought this was to see if I was lucky enough to get one of the bogus ones. The teardown would have been just as interesting if it had actually had a high voltage ion or ozone circuit in it.

Like all these bogus products, it wasn't even designed properly even as a bogus product. The circuit board is insulated from the case by luck, there's no fuse and the guts fit so badly that it's really hard to assemble again without squishing the LED sideways or having the negative stud on the side pop inside. And the blue LED is super-dim due to the use of an inappropriately high value resistor (26,000 ohm) meaning it runs at a fraction of a milliamp. Maybe it's supposed to emulate the dull glow of a corona discharge ozone generator.

However, all is not lost. I improved it so that it now makes the air minty-fresh.
