Spoken like someone that should probably be using a desktop.

Personally, having backup batteries is a requirement for the places I work.

Yes, that's why USB-C powerbanks exist. I can charge my laptop from one and it's nicer than lugging around laptop batteries, plus the laptop can be thinner.

Such a bizzare way to respond.

Laptop being thinner is a trade off you're willing to make, I am not.

Charging a battery with another battery is extremely inefficient.

Lugging around laptop batteries is exactly the same thing as lugging around power banks, except laptop batteries don't require a dongle and a cable to tether you to a table.

Laptop batteries mean you laptop can continue to in fact work from your lap.
