The AC side voltage/frequency doesn't matter as long as you have a wall adapter that works for that situation. The device being charged sees a USB power source and doesn't care what's driving that.

(Also note that many, but not all, common wall-plug USB power supplies are natively designed to work under both voltages. It's usually just matter of having the appropriate plug adapter to connect the pins from whatever sockets are used abroad)

The outside shell of the connector is electrically neutral, the only points in the connector with a different voltage are inside the connector, and no properly designed device should ever supply power along a USB+c connector without verifying it can receive power

Wall plugs have two different exposed conductors an inch or so apart with a over a hundred volts AC between them

Side note, curved escalators can be made, but they're very expensive (I've never seen one outside of Las Vegas) and take up a huge amount of floor space in comparison

Look at it another way, a person who for years has been able to handle having a few hundred dollars in revolving accounts, and never missed a payment, would appear as a lower risk than someone who has never had any kind of loan before.

The general idea of a credit score is that is a numerical summary of a person's credit history.

Credit cards are among the easier ways to establish a revolving line of credit without any additional spending, so they're often discussed as ways to do exactly that.

The kinds of customers who would shop at warehouse clubs generally would have no issues spending about $60/year on a membership, and these warehouse club chains generally choose locations where there is no shortage of customers

If they didn't charge for memberships, prices would have to be adjusted elsewhere to make profit for the company.

The person checking IDs at the checkpoint isn't investigating which airline you're flying on, they're just checking you have a boarding pass issued for that day and that you're the same person named on the identity document.

It's the traveler's responsibility to know where they need to go, and airline staff and communications will often help.

There's not much of a point in overly restricting the windows OS.

End users who don't want to pay for it anyone are just going to find a workaround.

It's the OEMs and corporate users where Microsoft makes their money, and who also lucrative targets for legal action if they are using it unlicensed

It's a similar strategy to how Adobe has protected their creative suite products: they rather have college students and personal enthusiasts familiar with that particular software than fight tooth and nail enforcing licensing on the average person.

A typical US household outlet can only be used for 1500 watts continuously, and that's sometimes complicated by the fact there may be other devices on that same circuit that are also drawing electricity.

1.5kw isn't a very fast charging speed for electric vehicle batteries, especially for vehicles driven every day or close to that.

A household EV charger is just a special connecter wired up to a power source rated for a higher current at 230v.
