xkcd: dual USB-C plugs
Oh, nothing could go wrong with that.
I keep intending to bring that up and ask Hal wotthehell it
means. He'd probably know. I can't tell the thing from a
standard two-prong plug.
Well that's kind of the point. You can plug it into a wall outlet.
But you absolutely shouldn't!
Hilarity will Ensue.
It may be a parody of the all too frequent real situation
of a computer interconnect plug being found inserted
firmly in a socket of the wrong shape, or even a socket
of the right shape but with an incompatible purpose,
such as keyboard/mouse or networking/phone line.
Experts aren't immune to doing this though usually
it precedes a user calling the IT helpdesk, but usually
only expensive equipment is hurt. This one's deadly.
A couple of other thoughts come - that some USB-A
appliances - disk drive, CD-ROM - use relatively a lot
of power and require to be plugged in to /two/
USB ports - one for power only. (Always from the
same source device.) (USB-A is the somewhat larger
rectangle that is somehow wrong-way-up the first
/two/ tries.) And also, some wall adapters to output
USB power do have USB sockets lined up. There's
pictures of a thing here, for USB-A.
