After switching to solar DC and batteries I suddenly cared a lot more about ac/dc power inverters needlessly wasting my limited energy supply.
Slowly I figured out how to power my devices without ac outlets. Mercifully 5v,9v,12v,19v at 1-5A are pretty standard values for most lower powered DC appliances.
A good DC barrel plug 5.5mm universal adapter kit, a usbc-PD adapter cable with manually selectable voltage levels to 5.5mm barrel plug, and a car plug to dc barrel plug universal adapter kit have taken good care of 95% of my adapter woes.
It feels sooo good to figure out how to power something directly with USBC and see the wattage drawn get cut down significantly.
Whats my point? If people knew a little bit more about the finer details of power supplies and dc barrel plugs most of their box of junk cables could be phased out with confidence. If you have 20 year old electronics with some weird incredibly specific voltage and barrel plug I would heavily consider just getting a new version that runs on usbc-pd or a more standard power rating. And if I ever need an old video cable? You'd better believe amazon and eBay still got it.
I really like your comment. Nothing gets me going more than eliminating unnecessary waste and streamlining the system to a simpler one, even if it is more work. ๐ค
