Are USB-C Chargers Interchangeable?

They don't. It's hardwired to the base, which the kettle detaches from. Do you still have a kettle with an old skool lead?

No. We have one that sits on a base too, but I had to go and check just now.

Nerdy pedantry alert!
A handy image for reference (odd is socket, even plug)
These days it will be a switch mode power supply not a transformer, they get to the same place but in very different ways.
And they are of course wrong that is a C14 connector and only rated to 70°C an actual kettle lead is a C16 has a notch in the base and is rated to 120°C. And of course neither is to. Be confused with the C6 or clover leaf connector.

Exactly!

I gave up engineering as a profession soon after I left university, but every now and then my inner engineer finds an outlet....

I have several rechargeable einhell batteries (+drill/torch/strummer etc). I see that they sell a Bluetooth speaker that has a usb charge point. Wondering it this could effectively turn these chunky batteries into power banks for mobile phone etc ? Any other way to use these for phone charging on extended holiday trips etc as I don’t need another Bluetooth speaker?
Can one work out how many times a 3.0Ah 18V battery would charge my pixel 8 phone (4575mAh)?

None. It's 18v instead of the 5v available through USB.
You'd need some sort of adapter to drop the voltage.

Alternatively known as a PC power cable.

The spec. Shows USB output 5v 2A.....so must be some integral transformer built in....

There would be in the case of the cordless speaker but not directly from the battery.

That wouldn't fit my PC.

Exactly. And yet it's a PC power cable.
Everyone knows what is meant by kettle lead. If you want to be precise, then pick the type on the diagram posted above. But PC power cable isn't very helpful.

3x18 = 54 watt hours
3.7 x 4.575 = 17 watt hours
so approx 3 times -assuming the declared capacities are accurate.
And it's unlikely to be a smart charger - so slow...

Well, I hope you correct him when he calls them PC power cables and not IEC C13 connectors.
Why do those modern switch mode power supplies 'not transformers' cause such massive interference on AM and SW radio?

They use high frequency for efficiency and to use far smaller transformers / inductors / capacitors - with lots of harmonics.

I try not to think about how many we have left plugged in permanently for computers, phones, TVs, streaming sticks etc. The stairs are made of wood and the window openings are too small to get out of and then there's the drop...
