True, but this has no bearing cos the device will draw as much current as it needs, up to the maximum deliverable by the power supply. AT that point the power supply will current limit or shut down (or even reduce) current output.

Quote:What those fast chargers do is to supply up to 20 Volt in riple mode to force more current into the device being charged. This is well above the standard 5 Volt expected by the Prime, i would say.

Begging your pardon, unless there's something being lost in translation?, but this is nonsense!. USB is USB, it follows standards.
USB3/USBC allows a different charging voltage which can be 20VDC, but that's USB3/C

This. I charge mine with several Apple/Samsung USB bricks. They all work fine, as USB is designed to.

If you are using something that uses USB3/C or whatever, taht could be the issue. I have a couple of USB C devices whose bricks cannot be used with other devices.
