It's relatively easy to measure today, looking at the mineral layer just under the layer of ashes from a volcano from just after said event.

If it happened TODAY it might not send us all the way to the stone age, but the worst Carrington style events happen about a decade before the micro-nova, when the Earth's magnetic field is at its weakest. But give it 4-5 years of additional decline, and we'll be close.

Any X 7 flare might do it today, although I don't know the exact classification of the December 16, 1988 flare which was the most disruptive one that I can personally remember, with our grid in Québec going down for over 3 weeks.

Bottom line, there is quite a bit of data.

I rephrase: How do we know how powerful it truly was on electronics if there were very little electronics back then?

Well, it is known that solar flares can range up to a certain energy level, and the geomagnetic disruption levels are easily calculated per flare energy level. The stronger flares will feel like the EMP from a very strong nuclear weapon... EVERYWHERE.

And once again, it is known that a strong EMP kills everything electrical and of course electronic. It is inescapable and true.
