... and the photo when there is a toothbrush charger or re-chargeable razor charger plugged in?

... and you've just re-posted them. However, as I've asked, where is the corresponding photo when there is a charger plugged in - without that you are only speculating that the voltage won't fall to acceptable levels under those circumstances.

Not got one, but I did have an overheated rechargeable shaver that I had to throw away due to this.
... and your reason for knowing that such was the reason for the shaver's problem was?
As I said, whilst there is a theoretical basis for a potential problem, we are merely seeing speculation about whether there is, in practice, an actual problem. Given that rechargeable toothbrushes have become pretty ubiquitous, I'd be surprised if we hadn't heard more about 'problems', if they were common - and, indeed, surprised if the manufacturers of the shaver sockets had not responded accordingly.
Because it ran very hot in the shaver socket, but was normal connected directly to the mains.
Shaver sockets don't seem to have changed. I have measured lots and all appear to give nearly 280v output. But perhaps toothbrush manufacturers are aware of it and actually rate their products to 280v but don't tell us. But why take the risk when you can (except with MK shaver sockets) use the 110v outlet.
Well that's interesting- what's in them to allow that trick then? (I've never really thought about it tbh, v small shoddy isolating transformer?)
Yes, but you're still talking about the off-load voltage. I don't know, and you clearly also don't know, what voltage they produce when powering a load such as a toothbrush charger.
Indeed, but a toothbrush charger is a somewhat lower load than a shaver so I guess it is way above 240v. If I can find a 2 pin 2 way adapter lurking in the garage I'll have a go at measuring it sometime.
It's not a trick, or necessarily particularly shoddy. Being (necessarily) small, and not designed/required to supply large currents, the transformer will probably we wound with very fine wire, with an appreciable resistance.
If they designed such a transformer so that it produced 230V or 240V with no load, then that voltage could (because of the internal resistance of the transformer) fall to an unacceptably low level when a main-powered razor was plugged in. They were therefore designed so that the on-load voltage (with a mains-powered razor) would be around 230/240V.
The problem is that these 'other things' (chargers) which probably require much less power than a mains-powered razor have come along, and people now want to plug them in to something that was not actually designed for that purpose.

It may well be - but as you now admit yourself, you are guessing.
Don't forget that Winston starts out with a higher supply voltage than most of us.....
To be fair to winston (he does occasionally deserve it!) I think the supply voltage he's always talking about (and probably has) is much the same as the supply voltage that most of us usually have (in fact, a bit lower than the supply voltage I usually have).
Kind Regards, John
Yes, I know.…
