Agree to a degree.
I agree in your observing same as you, most owners don’t care.
But these same very non-caring people also find their phone about to turn off flat and I get out my Powercore, 3-in-1 cable, top off their phone, they then say “where did you get that… how much did it cost…”
I think what most people need to do is carry a Powercore, even if just one of the lipstick shaped Mini+ but I’d always recommend a 10000.
They then don’t ever really get remotely flat, and then don’t really need fastest possible charge and then can use whatever older charging tech when they get to bed.
10W standard USB socket is perfectly fast enough, if you’re not in any rush.
More Powercore, less Watts. Then people can live and use their expensive phones as much as they like , enjoy their spend, without angst.
The flaw with this suggestion is many of the people who don’t care about phone charging, is they just end up with a flat Powercore instead as they didn’t plug it in at night. This is why the Powercore Fusion idea has its merits.
