Try remembering the 19th century  philosopher (who was admittedly a bit of a weirdo, but even a stopped analog clock is right twice a day!) Thomas Carlisle. He is paraphrased as saying "The world is full of men, mostly fools."

Intended in that was also women...(it's arguably sexist these day to leave them out of generalisations..)

I did sign up for Ham test online an hour a day and in 30 days the average person should be ready.  I am far from average.

Sure ya did. Right up to the point where you say you didn't.

I always wonder why YouTube video producers think we want to see them? Much of their credibility rests on their appearance. And why are they always in the middle of the screen and their product or presentation is off on the side? Haven't they learned anything from all the years of television presentations?

It's called "drivel" and if you still have the receipt to that gift I'd return it for exchange or refund. Obviously broken.

I don't know why this jealousy thing keeps getting mentioned, there is none of that here.
I also made mention that the utuber has a few good points on other tubes.
But to say that a usb adapter will "destroy" you car is just plain wrong.

...
His claim is that those little usb adapters that you plug into your automobile lighter will sent out rf thru the use of an ac signal to create a 5v source....

That part is correct. A DC-DC converter generates a square wave (AC) waveform in the process.

There is probably no waveform at all. It could use something like a 7805 to do the job.
Certainly not a full SMPS as he claims.
It could possibly be a bucking type regulator, but even that would be an overkill.

A 7805 wouldn't work very well in that form factor. To supply 5 volts at 1 amp to the USB connection, the regulator would need to dissipate north of 8 watts.

The common form of regulator for this application is the buck topology. That is simply one form of an SMPS (switch mode power supply).

Wait.

Did you just say that they gift you have is “intellectual dribble”?

All righty then.  Who are we to argue?

Definitely belongs on a billboard, though.  Just sayin’.
