  • far different size.

    Size first. Power electronics don’t have the same miniaturization benefits (or expectations) for laptops as they do for phones. Some factor here is that there’s just a different convention for these two different types of devices.

    larger bricks that have separate mains cable which plugs into the brick

    There’s a manufacturing benefit having one circuit where you can just change the mains cable for length or country adaptor types. High probably the wall warts have the same ability, but it isn’t as obvious if the plastic parts are press fit.

    Why is that so?

    Some laptops could run off of 65 w, but only the very basic types. An Alienware m18 R2 gaming laptop has a 280 w adaptor and it isn’t close to the same size or price as a phone adaptor.

    Same for phones. 65 w is pretty beefy for a phone charger. It will come down to the requirements of the device.

    Generally speaking, a charger can have more amps than the phone or laptop requires and that’s usually okay. The voltage is what you have to be careful about. 5v is kind of a common electronics safe voltage. Good chance all these “universals” chargers are 5v.

    Again, something like an Alienware m18 R2 is going to require more than 5v.

    Or is it simply cheaper to manufacture while being sold for the same price?

    Good chance of that. Much easier to price fix on big warehouse type online marketplaces.










  • MMA has an interesting trajectory where people actually didn’t know which style would win at first. Dudes in gis would actually fight some dude in kickboxing gear. Look up some old MMA fights and you’ll see the fights were usually awkward and bad.

    Someone else called out in this thread that the rules of MMA influence what wins. I think that makes sense. They can’t just immediately kick each other in the balls.

    I say join a gym and try out a few fights just so you know what it feels like to get punched in the face, and then do like everyone else says and get good at cardio. If you have asthma carry concealed I guess.
