On just buying a 800 watt 'two' stroke petrol generator from Aldi, we

connecting to
televisions or other sensitive electronic equipment.

Likely it is not just acoustically noisy but electronically noisy too
and the ignition system radio emissions will cause snow on a portable
TV. It might be so rough and ready electrically either voltage or
frequency wise that it could fail or wreck some old sets completely.
I'd expect most modern switched mode PSUs to cope with almost anything
but then you are taking a risk since the maker says it is unsuitable.



I would have said the exact opposite of that. Linear supplies with a
nice big chunk of L in the way, are pretty much unconcerned about such
nasties as spikes, whereas switchers will fail if you just look at them
wrongly on a day with a Y in it ...


No. they just rectify teh peaks.

But iron transformers dont like odd waveforms.

Having said that, ive used a genny to power a laptop for watching TV on
in a camper.


However, that said, I would agree with everyone else that using this
with modern electronic equipment would not be a good idea. OK to run a
few lights (but not CFLs or electronically ballasted linear
flourescents), and maybe power tools, which is probably what Aldi had in
mind for it. I've actually found Aldi to be pretty honest in this
respect. It's cheap, and they know it, hence the warnings.
