I sympathize with the OP, Carmanje!
When Apple made a big-to-do a couple of years ago about being ecologically conscious and dropping the included power adapter, they specifically emphasized that it was because most people supposedly already had lots of power adapters laying around!
They meant, of course, USB-A power adapters, just as Night Spring mentioned.
Plus, unless you are into following Apple, visiting MacRumors, and poring over tech news, none of that would have been on a typical consumer’s radar screen.
Until this past month, they did NOT even explain on their product pages, OR under What's Included in the Box, that customers needed to buy or already own a separate USB-C power adapter. They put it in fine print, too, which is not consumer friendly, either.
As a prospective buyer. I found the entire situation confusing and, I have no doubt, that many were surprised Christmas Day to discover they needed to buy an adapter! It'd be like selling a car without a key to the gas tank — or a Mac without a power adapter.
Also, as I recall, they changed the charger included with the Watch SE last year from a USB-A to a USB-C one. That, too, was NOT made clear. It also undermines their point that many or most already had a bunch of power adapters laying around. USB-adapters?! No, many of us don't!
