Cyanoacrylates (super glue) is very brittle which doesn't work on

dropped the wall wart on the floor. I suspect more glue would be
better, but have never tried it.

There are "toughened" cyanoacrylates which are supposed to be better
about this... the ones I've seen apparently include some extremely fine
rubber particles or other fillers. Most of the big glue manufacturers
seem to sell one variant or another of this.

I haven't spotted any mention of hot-melt glue guns - not suitable?

I've not had much luck.
Hard to get it spread around before it gets too cold.
Doesn't stick well to smooth plastic.

Might be interesting to roughen the surface, lay it on thin, assemble,
then reheat with a heat gun.

My plastic welding experiment seems to be plenty strong with just
four patches, one in each corner.
I put a tie wrap around it just in case.
