Yeah - don't bother, replace with a decent socket, and buy a slimline
plugtop USB charger.

Taking up one of the two sockets whilst doing so, no good if you want
to charge your device in the kitchen in the same socket(s) containing
the kettle or toaster.

Apart from what you found, the USB charging standards improve every
couple of years and any charging socket will be obsolete in terms of
providing the max charging current soon enough.

Personally, whilst my Samsung Galaxy S7 will fast charge, I generally
don't because I'm not sure the extra heat generated is good for
anything (charger, battery, phone etc)?

Plus I think you have to use a 'fast charge' cable (even on the right
charger) to get a fast charge?

I'm not sure if the charging capacity of the mains socket USB itself
is going to limit the charge rate of 'most devices', especially, if
used singularly and without any special cables?
