>If it needs to be plugged in all the time, why do you need a laptop? Why not just a desktop?

I never said it needs to be plugged in all day, I said that's where it spends most of the time. Because desktops take up way too much space and because sometimes you leave the house with your computer for work or leisure. And when I do, I don't need more than a few hours of battery because I don't like doing work outside the ergonomics of a proper desk.

>short trips, airports

And do you do a full day's work in an airport?

And when you travel via airports, you probably don't air travel in just your shorts with nothing on you, other than your phone, keys and wallet, like you're going to the local pub, but I assume you also have a backpack/bag with you for your laptop and belongings, which can also fit a <100g charger you need for your phone anyway.
