Essentially whatever you do will be obsolete to some degree within 2 years.

Then make sure the things you buy use the standard 5v? ;-)

It's not the PS which is obsolete. It's makers moving goalposts to try and
make you buy something new extra yet again.

If Apple or whoever wish to use a non standard charger, why not invent a
new connector too? They obviously not very upset about it being
standardised.


Well, you can, if you never want to use new things and/or enjoy slow
charging.

I'm starting from the premise people might actually want a practical
solution that can evolve as all tech does ;-) The one true standard in
all of this is 230-240VAC 50Hz - so it's probably the best place to draw
the demarcation point. 5V looked solid for a while, but with the caveats
the current kept jumping.
