@nf3xn Standard endurance for USB-A ports is 1,500 connect/disconnect ("mating") cycles.

@ryanc @nf3xn

Good USB-C endurance is 10,000 cycles.

Cheap endurance testers for NEMA 5-15P have a counter that goes to 999999. Expensive ones go another digit.

@dashdsrdash @ryanc @nf3xn is that more or less than a standard AC wall socket?

@Zeugs @ryanc @nf3xn

NEMA is the US standard, 5-15P is the 3 conductor 15A plug side that 90% of the appliances you can buy use, 5-15R is the wall outlet side that 90% of the walls will have. The exceptions are mostly 220/240V outlets and plugs for large air conditioners, electric dryers and such.

Very old houses will have ungrounded 2 conductor plugs; some appliances use ungrounded 2 conductor plugs that work in NEMA 5-15R.

@Zeugs @ryanc @nf3xn

I checked the DE standard, and I'm a little surprised to see manufacturers boasting about 20,000 insertion cycle testing for type F / Schuko plugs. I would have guessed 500000 or more.

@dashdsrdash @ryanc @nf3xn
I could imagine that the plugging frequency could differ for USB.
20.000 is a bit more than two 2 plugging cycles per day for 25 years.
If you use it that much you should think about a good durable power converter in the wall. 🙃

@Zeugs @ryanc @nf3xn

I don't believe I have any devices which use USB A or C and will last 25 years.

I have several NEMA 5-15P devices that are more than 50 years old and still in reasonable condition...

but in any case, the question is what you should put into your walls. I wouldn't put USB in the wall; as @cstross said, we'll have a new standard every few years.

@dashdsrdash @ryanc @nf3xn @cstross We need the USB forever* standard.
*Support 50 years

After 25 years. "Why was it called USB forever? " "Because it takes like forever to transfer data."
