You can get USB cables that output selectable voltages from about 1v-20v to a barrel jack. I just make sure the power requirements are labeled on the device and get rid of the bulky wall adapter. I have to keep a few weirdos like the N64 power supply, but I was able to free up a significant parcel of closet space.
So you are saying that there are USB cables that can replace an AC adaptor? So I can run an older unit off my computer using a special USB cable? Or in my car?
This is interesting, I’ll have to look into this.
I’m also wondering if there is a way to replace the power supply within a gadget, to convert it from say, 2 AA batteries, to being rechargeable with USB. Could you collect the little rechargeable “beans” from old headsets and such, string them together, and wire them in? Or maybe hook up a small portable rechargeable phone bank. Is it possible to wire in something like that?
In case it isn’t apparent, I know nothing about electronics.
I am not sure what you mean by beans. But I have shoved some alligator clips into a battery compartment in a pinch. Two AA batteries in series are 3v so that is the voltage you would supply for that. Doesn’t come up much because I have quite a few rechargeable batteries around. I did recently find my old Tamagotchi and have been considering putting it on display somewhere after Frankensteining a power supply for it.
No, not those. I’ve taken apart small electronics like headphones, and found what I thought were the “batteries,” but maybe they weren’t. I can’t find any photos of what I am thinking of.
I can only conclude that I don’t have a clue what I am talking about. Please ignore.
I am saying that. Just checked one that I have and it appears to be capable of supplying up to 60w. Give it a try before getting rid of any official adapter. Make sure the polarity is correct (most things besides music gear are centre positive).

By beans, I mean those little batteries that you find when you dismantle old headphones and such. They don’t look like batteries, just little blobs.
I am wondering if you are talking about capacitors. Like this?
