Sometimes Frank is right but Frank is simply wrong in the case above.

I get anything I want for free from Amazon Vine, and as a result, I must
have dozens of chargers, and the fact is that they're different.

When you review chargers, you'll see that the specs are completely
different between them and when you review items that are being charged,
you find that what Frank said (and Arno said the same thing) is just wrong.

The fact is there are plenty of low-power devices (not smartphones though)
which simply will not charge with a modern PD/QC USB-C charger.

They just won't.
That's just a fact.

Frank and others may be ignorant of that fact.
But it doesn't change that it's a fact.

Also, Frank is wrong on a few other counts, where some chargers are QC and
some are PD and some are a combination and even others are PD and QC
advanced standards, etc. There's a mix.

To say that any charger will charge a phone is like saying any fuel will
run an engine, whether it be jet fuel, kerosene/diesel or gasoline.

That's just wrong.
The USA M35 series military 2-1/2 ton 6x6 cargo truck could run just as
well on almost any fuel, but you won't get the charging speeds you pay for
if you try to charge a $2000 phone with a $5 5-Watt 1Amp charging brick.

Those who claim otherwise are simply clueless how phones actually charge.
