Hi Arno,

Good. Because anyone who wants to be respected in this discussion needs to
distinguish between any old charger and specific high-wattage chargers.

This is important because Apple & Samsung on purpose do NOT make that
distinction when they tell people they have plenty of chargers at home.

And the correct term is not "PD" but "USB-PD".

That's a good point, but I'm gonna stick with PD; especially as I generally
link it with QC (and I could even link it with AFC, which is Samsung's QC).

And both protocols,
USB-PD and QuickCharge come in different versions and work with
different voltages to achieve the wattage without burning the cable or
plugs.

Yup. I get any charger I want off of Amazon Vine for free. Plenty are
double-digit voltages for short periods of time, as you must be aware.

 Do you even understand why a higher voltage is needed to be able
to deliver 20, 40 or even 65 watts using a USB-C cable?

Arno - Amazon selected me as one out of millions who knows how to write
good reviews - so I've written plenty of charger reviews - so of course I
know the difference. I have an EE degree among others for Christ's sake.

Do you know why high-tension lines are hundreds of thousands of volts?

And I also have a USB-C powered soldering iron:

So don't tell me, that I have to learn something in this area.

Actually, due to poor design probably, I've run across some Amazon USB-C
non-phone items (e.g., clocks, lights, earbuds, etc.) which will NOT take a
charge from PD/QC chargers. They actually need the dumb 5-Watt bricks.

Before you say that's crazy, it's not, but I do agree it's poor design.

I know it for two reasons:
a. The damn things don't charge on the fancy chargers, and,
b. The instructions say so.

Having said that, they "should" charge on any charger; but they don't.
Sigh.

The point is that everyone has 5-Watt chargers but they're useless.

 
I don't have 5-watt chargers. Mine have at least 65, some even more.

Most of us have entire boxes of 5-Watt chargers; did you throw yours away?
