Being as we are in the cyber world these days, many of us have little electronic things that take cords. Or we get things that need cords but come without them. Two cases.
(1) I have an Olympus digital camera bought at the Goodwill for 59 cents a pound. Didn't work, lens was stuck with a piece of sand that I cleared out and it worked fine after that. I prefer this digital camera to a smart phone, better quality pictures. Anyway, of course it came without a cord, memory card or anything else, it was just loose in a junk bin. I bought a memory card for it after I got it working; didn't want to spring for a card if it wasn't gonna work. It had a small amount of internal memory to enable me to see that it was functional. So when I've uploaded pictures, I always do it via the card. I have a little adapter do-dad that my son gave me, takes all imaginable sizes of camera memory cards, plugs into the USB port. This is all well and good, but how about those pictures trapped in the internal memory? For those, you need a cord to plug the camera directly into the USB port.
(2) Case 2, my son gave me a smart phone, bare bones, he set up some kind of arrangement where I don't have to pay a monthly bill. The arrangement has changed since he gave it to me, so I don't know how it works now, but he pays for it so I don't concern myself with that. But being bare bones, the manufacturer cheaped out and didn't include a cord with this little device. I don't use the thing very often, but enough times that I've trapped some pictures and a couple of videos in it. One time, I sent a couple of pictures to my own email account but it seemed like a nuisance to do it.
Solutions! Cords for everything are available on eBay! You just pay money! And not very much, as it turns out. I got little cords for both of the devices mentioned above for about $3.50 each, you just have to know the model number of the contraption for which you need the cord. One came from the US, one from China. Now I've unlocked those trapped images and have them in my PC! Some dating back to 2015! How about those exclamation marks?!! !!! !!!
All those little crappy electronic things are highly competitive in price, a million people are selling them, all in a race to the bottom to get your money.
I have a new policy now. Don't save cords, adapters, power supplies, etc. Why wind up with a box full of tangled junk, most of which you will never use again and much of it you've long since forgotten what it's for anyway. Shittsall available on eBay for next to nothing, let somebody else be the warehouse.
Let's be honest here. How many of you have a box full of little black AC to DC power suppliy units? Of who knows how many different outputs. Many you have saved after the device they originally powered is long gone. You kept it, just in case. Yeah, right, first of all, odds are you won't ever match voltage output and connector plugs to any other thing in the future. That is, if you even remember you have it or want to spend the time digging around for it and untangling it from the many other orphan and useless power supply units you've retained. Go ahead, tell me I'm wrong about this.
