The dream of "one cable to rule them all" is finally a reality, and dozens of devices are better off because of it. USB-C gave us permission to own fewer single-use cables than we used to, and it opened the door to interesting functionality that would otherwise be impossible, like running data, power, and video between a single port on a laptop and a monitor. Still, USB-C as a standard is plagued by a lack of strictness, and it's created some brand new headaches as a result. One shape, a million uses Can you name every USB-C spec off the top of your head? I can't! If you're shopping for a USB-C cable and you see one that's advertised as "USB4," it's not unreasonable to assume that the cable offers really fast charging, high-speed data transfer, video capabilities, and cutting-edge stuff like eGPU connectivity. After all, USB4 is the latest specification. A big new number should equal big specs. Unfortunately, the "USB4" label can mean a dozen different things; it's a super-loose definition of a cable's capabilities. Some USB4 cables don't support PCIe tunneling, USB4 cables aren't required to support video over DisplayPort Alt Mode even though USB4 ports are, and you might be looking at transfer rates anywhere between 20 Gbps and 80 Gbps. Things get even worse when you shop outside of the USB4 milieu. A USB-C cable might deliver super-fast charging speeds but lack any form of data transfer support, for example. Manufacturers barely even seem to know what they're selling half the time; they just vomit a bunch of numbers that may or may not be correct in their Amazon listings and call it a day. And some brands purposefully violate USB-IF standardizations, because why not? Chinese smartphone brands like OnePlus and Oppo hit non-standardized charging speeds by adding an extra pin to their USB-A to USB-C cables. The original Nintendo Switch went a bit willy-nilly with its charging, which is why its power adapter won't work with a lot of phones and laptops (this non-standard charging scheme may have bricked some consoles in 2018, too, but I don't believe that this has been verified in any real way). Nothing is labeled You bought a nice USB-C cable. Can you actually remember its specs? Credit: Andrew Heinzman / How-To Geek I have no clue what most of my USB-C cables are capable of. Maybe I knew when I bought them (assuming that the manufacturers were honest), but that knowledge is gone because the cables aren't labeled, and there's no practical way for me to check a cable's specs without buying a dedicated tester. Some brands, like Plugable, do print detailed specs on their cables, but I shouldn't have to buy from one of the more expensive brands just to enjoy this courtesy. This problem also extends to USB-C ports. Do you know your phone's maximum charging speed and data transfer rate off the top of your head? How about your laptop? I know that I've overpaid for USB-C cables and power adapters because I assumed (or didn't bother looking up) that my MacBook Air couldn't take advantage of a 100-watt output, or because I thought that my monitor needed a ThunderBolt cable when it really just needed a DisplayPort Alt Mode-capable cable, for example. Though I should note that most laptops and desktops now use Thunderbolt or DisplayPort labels to highlight which ports you should use for high-speed data connections, external monitors, and things like that. Plus, a PC is something that you familiarize yourself with over time, while cables may spend a few years parked in a drawer before they're pulled out for a new job. The lack of labeling on cables is a far bigger problem. We all own too many USB-C cables And 99% of them are genuinely just trash Do you ever find yourself leafing through a twisted rat's nest of USB-C cables, just hoping to find one that actually works well with your phone? Chances are, you've got a wad of USB-C junk stuffed in a tiny drawer that can barely close because it's so full. And most of those cables are garbage. Years ago, every new USB-C cable that entered my home was like a free prize. I had two or three of them, and then my collection accumulated, and accumulated, and kept growing until I had too many. And yet I still find myself buying new USB-C cables every now and then because most of the ones I own are useless, or the good ones in my possession are impossible to find because they're buried under a mound of spindly little white USB-C cables that I never asked for in the first place. Stop giving me free USB-C cables, I don't want them! To be clear, I'm not advocating for phone brands that shortchange customers on USB-C cables or power adapters. Expensive devices that are capable of PD charging, high-speed data transfer, DisplayPort Alt Mode, and other fancy features should come with the equipment to utilize those features. But little doodads like flashlights or walkie talkies that happen to charge at 3 watts over USB-C don't need to be accompanied by a crappy 2-inch-long cable. It's a waste of money and resources that burdens customers with the guilt of either throwing a cable in the garbage or tossing it in a drawer along with a bunch of other junk that will never be used for anything.

It just disappoints us sometimes In all the ways that really matter, USB-C is a resounding success. It's a universal standard that can replace all kinds of cables, from HDMI to the humble DC barrel jack. But it'd be nice to hop into a time machine and lay down some laws, like a labeling requirement for cables and ports, or a strict classification system that customers can understand at a glance.
