I've attached a picture of the eBay thing I tried to link earlier.

This inverter is working quite well, but, like you maybe can conclude from the transformer size, its operation frequency is ~42kHz. That's no problem, if you want to feed for example a mains LED lamp or any other device, where the AC is rectified again to a DC, but you cannot use it on any device with a 50/60Hz mains transformer

Was hoping the output would work on a WC ionizer.

Back to back transformers, it's actually a good ol' boy way of isolating the mains without expensive isolation transformers.

Ever heard of MOT's? (Microwave Oven Transformers) - freely available providing your local council junk yard inspector is not being an arsehole.

Any time I hear of someone playing with a microwave transformer, I swear I can hear Darwin cackling with glee.

I've been playing with them for many years, they are not any more dangerous than any number of other things people play with. Flammable materials, firearms, cars, power tools, etc. It's simply a matter of understanding the risks and using a bit of common sense. The primary side DC bus in just about any SMPS can kill you just as dead if you aren't careful.
