> Maybe all the complexity around this is too much and people just want to plug it in and quick 100% as quick as possible and will change their phone regularly
It's this, 100%. The nerds that care about charge temperature and battery degradation and proliferation of incompatible charging standards are a rounding error, most people just want to know it can charge fast in case they forget and need to leave soon.
I am happy with my Chargie [1], an interposing dongle which provides a Bluetooth receiver and app that lets you set arbitrary preferences on your phone and fast charge, slow charge, or turn off the charger at configurable state of charge setpoints or times.
I had never thought such thing existed commercially. Mainly because I had looked for it myself in addition to asking about it without results.
It needs an app but doesn't mention interoperability. There, I said it. It is not perfect.
At least they allow you to set-up-in-app-and-use-without-app which is more than many products.
>needs an app
Now imagine the same product but with different physical toggles or buttons on it for all the different charging modes. No apps. That'd be great.
