“Owing to the significant amounts of electronic waste caused by unused chargers …”
Really?
Really?
Because no, you can't. And that's the whole problem.
GP specifically said the chargers had standard USB ports - and they do. Either A (old) or C (new). You're talking about the cable which is a completely different thing (obvs.)
Roll on more USB C dominance.
Rip the barrel plug off of things and replace it with USB-C input, or make your own USB-C 'dongle' to power anything that needs 12v.
Ridiculous. I’ll take throwing them all in a landfill if I never have to use or see one again.
