| Hmm, couldn't this be just the adapter's regulation getting started,

The charger was plugged into the wallsocket all the time, it's dealt
with its inrush current hours ago.  I was sat there plugging and
unplugging on USB socket side.

| Could be. We also have a bunch of specification-violatingly large

A 2A-capable wallcharger should just blow right through them.
