Yes, a terrible idea, like putting a motor on a sailboat! I mean, why would you ever need 2 methods of propulsion?! (Some boaters even bring oars and towline! Insane!)

That analogy is silly. Two methods of propulsion is a good idea - when the wind is not blowing then use the engine. If the engine runs out of petroleum use the engine. Having a proprietary power interface and a USB C interface that does the same thing is ridiculous.

  USB-C can’t charge nearly as quickly as a high power proprietary charger. In use USB-C needs to supply power for both charging and operating the laptop, so what might take 3 hours to charge with USB-C might take 20 minutes to charge with a dedicated connector. That’s not to say every laptop’s proprietary charger will supply noticeably more than 100W, but many examples exist.

    I'd be surprised if a 13" Surface doesn't charge well enough at 100W, though.

      13” Surface laptops had up to 90Wh of battery. Batteries get hot when charging due to inefficiency, meaning it takes more than 90Wh to charge a 90Wh battery. Subtract the power demand while in use and your well over an hour to fully charge. By comparison a quick charge to 80% in under 20 minutes while under full load should be possible assuming sufficient cooling and power. That’s not a huge deal most of the time, but it’s still plenty useful if your sharing a single outlet etc.

        I’m sorry, what laptop charger has a brick that’s over 100W?
        oblio 6y ago
        There are some. Thinkpads can go to 135 and if I recall correctly, maybe even 170W. The bricks weigh as much as an ultrabook, though :-D

        Here’s a 230W example: https://www.amazon.com/Charger-Adapter-GTX1070-RTX2070-RTX2080/dp/B0874KKC3G/ https://www.amazon.com/Charger-Adapter-GTX1070-RTX2070-RTX20... Their still common with gaming laptops like Razor 15’s. It’s ancient at this point, but a friend used to have a dual GPU laptop that used 2 different AC adapters at the same time.

A bad attitude and a bad analogy. A second charging port is redundancy, a second motor is auxiliary. Don't start about multiple usb ports because those are also auxiliary in purpose Edit: Not making a judgement as to if a second charging point is a good idea or not. I don't care, why not.

You obviously don't sail. You need a motor on a sailboat to either fight a strong tide to dock, to escape an incoming storm if the wind is pushing you towards a storm. Many other uses such as regenerating the batteries so you have your food not spoil. Sails/masts/rigging also fail so you need a backup to get you to port in an emergency.

  The true statement is that either I don't sail OR sarcasm is sometimes hard to pick up on the internet. I grew up cruising on my dad's sailboats, raced dinghies in college, and have owned a variety of sailboats myself, the last being a humble 35' Erikson. So, I would say it's the later.

    Awesome a fellow salt. Sarcasm was definitely hard to pickup but glad you had so much fun on the boats. I picked it up later in life and would have been so nice to have done that as a kid.
