I think smart TVs are a little more aggressive with their anti user changes because they see it as a captive audience. They market the hardware specs, then add ads to the UI. Streaming sticks really only have their user interface and user experience to market, so they’re a little less aggressive with the negative changes.

I suspect that you already have one cable that will charge all five devices. The device pulls the necessary current, the cord does not push current into the device. This means your most capable charger should charge all of the devices.
