It's not just the charging current. USB-C supports multiple charging

seem to be becoming popular just as USB is moving away from a single
5 V standard.


I rest my case, m'lud!

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

Whereas something like:

can be upgraded, takes little space, doesn't even cost a socket and can
be turned off ( or unplugged) when not in use.
