get a switch into the equation ASAP
That's about the size of it. However, how much arcing is there going to be in that switch?
Even with a crappy switch it's a one time transient at the switch end and along the cable, that doesn't cause
'spot weld' zaps on the device plug or mains socket,
as opposed to the straight out jiggle 'n sizzle plugging in
(russian roulette...) method to live 240/120 mains.
Switches are cheaper to replace, not that I've seen many go bad, especially the domestic style 10 amp rated 2 pole/single throw ones, they last ages, literally!
A
no frills quality power board/strip with individual switched outlets, or just one master switch, is a must have if using a lot of switchmode power warts and chargers,
preferably one with a small resettable thermal cutout switch (which most SHOULD have) in case of overloads or heat creating shorts.
They fit in the toolbox easily and squeeze fine into most laptop bags
