USB-C head-to-head comparison

The reign of the Lightning cable is over, and the USB-C era has begun — leaving us wondering what sets one charger apart from another. We do a teardown of Apple's Thunderbolt 4 and its competitors.

    I wouldn’t mind the various levels of there were a simple, consistent marking standard for speed and power rating.

      Same feeling honestly but don’t forget that it still would take research to buy the right one. Think about SD cards and their various speeds. You still need a chart to make an informed purchase.

        Sure. I think they could get a lot of mileage out of color/dashed bands to mark things on the cable like:

        • supports display out
        • voltage for charging
        • high speed data

        Each of those has a spectrum of support and could be marked separately. Maybe they put it on the connector, or maybe on the head, IDK, but something on the cable somewhere so you can find it in a box.

        Then repeat for your device, either next to the plug or in software. That way you could go look for the markings you need from the device on the packaging of the cable. I’m sure someone can devise an intuitive UX here.

        That should be a hard requirement for advertising USB compliance, not an optional thing.

          In a world of honest actors this is brilliant.

          In a world of AliExpress that’s just another way to lie.

            AliExpress products will always lie, that’s a constant. The important thing is for people buying stuff from reputable brands. If there’s an issue, people will usually blame the sketchy brand, regardless of the claim.

            It’s also obvious, not sure why it isn’t a thing. For example:

            • orange band means it supports “fast charging” and a number indicates the voltage supported
            • black indicates “high speed” data, and a number indicates the speed
            • green indicates display out, and a number indicates resolution

            So you’d have a colored band always at the same spot (for color blindness), and a number on either side of the plug in the color band. Maybe use Roman numerals so it’s easier on the eyes. No color band would indicate basic features (5v charging, slow data transfer, no display out).

            Previous USB standards also used colors on the plug to indicate speed, so it fits right in.

      They do have standard icons for them, but it’s not required to use them. Companies like Apple are a problem case there since they value a clean look over information, random Chinese brands sometimes use them.

      That is part of it, but I kind of feel like PCs and phones need better reporting to the user, if adequate data is accessible to the host.

      If I’m being bottlenecked in thoughput by speed or in power by the PD capabilities of a cable, I’d like the host to tell me if it can figure that out.
