USB charging question

waaaay less consequential.
If an equipment requires a minimum of power — say 3A — and the
interface does not supply it, it will not work properly. If, OTH, the sup-
plied power is the zillion A, these are still at the same voltage that is
the only crucial value here. Voltage is a must in terms of working con-
dition as amperes are an operation availability.
and the only way I know this to be true is that I was wondering the same and had asked my brother in law who's works with electronics .

Should read:
Just to clarify, as long as they all have the correct voltage,
A / amperes should never be less than the reworking re-
quirement but may be much greater?
Light is free… capturing it is not!

I'm guess the question mark at the end "much greater?" is a typo then? If it is, everything is crystal clear, thank you!

Voila!
