Japanese Firm's USB-C Cable Rotates 360 Degrees (tomshardware.com) 28

Posted by msmash from the how-about-that dept.
Japanese electronics manufacturer Sanwa Supply has launched a rotating USB-C cable capable of 240W power delivery but sadly USB 2.0 transfer speeds, Tom'sHardware reports. The $16 cable features a 360-degree rotating connector and is available in 1-meter and 1.8-meter lengths, with both USB-C to USB-C and USB-A to USB-C options, the report adds.

    Wow, raising the bar on the number of ads possible on one page. Awesome!

    These swivel-type connectors are awesome - my kid kept going through normal cables like crazy (they would always break apart at the sleeve near the connector due to tension) for the tablet we have; once I switched to these types of connectors I've not had to replace a cable since. That plus a magnetic adapter saves the connection socket too.

      Technology is so great that we don't have to adapt or change our behavior.

      • I could use power and data cables like that. I've seen it with phone cords and laptops where I use the same manner in picking up and putting down, yet still the cords rotate and twist for some reason after a while.

        Well, I suspect it's cable gnomes. They must also be the reason why the cabling from my stereo ends up tangled even when untouched for years.

        Interesting. I have been using NetDot magnetic adapters and cables on most everything I own for many years without a single problem (phones, power banks, communicators, headsets, headphones, tablets, flashlights). They are fantastic- super easy, fast, and protect the USB ports from damage. I just point the device at the cables on the desk and they connect themselves. Only thing I have never tried are laptops (but I only have one that i

        • Ditto here. Going on, at least 4 years now. The reddit post says static electricity, but I'm pretty sure the plastic around a port will store more static electricity than a magnet around it. It talks about static electricity due to humid climate but, I live in Taiwan. A tropical island. It talks about exposed pins, but the pins inside a USB port is just as exposed as some of these USB C magnetic connectors. Another thing they point out is, if it's possible, why didn't Apple or MS do it? But they did/do. App
  • the USB-C subreddit has a lot of examples of non-standard cables that look super useful but are electrically unsound in a way that can damage some devices.

      Yes, and "they're not always wrong", but overall they're also a bunch of pearl clutchers. iirc there's a blanket ban in that subreddit on asking about magnetic connectors in there because the ONLY answer is "though shalt use usb-c certified hardware only! anything else will burn your house down".

  • Anything USB3 and above are a fairly high-speed correction, a transmission line. USB3 alternates 1s and 0s to keep the cabled from becoming too energized or denergized. The cable makers caused such major discontinuities that there was too much reflected power and insertion loss.

      They are "differential pairs" not transmission lines.
      They don't "alternates 1s and 0s" either.

      Differential signals will have a voltage on one wire and a matching but negative voltage on the other.
      The wires are twisted around each other specifically so they WILL interfere with themselves.
      +3 and -3 constructively adds to zero. +5 and -5 also constructively adds to zero.
      That way there is always zero magnetic flux around the pair, and any other pairs in the same cable are also zero, so pairs don't interfere wi

    • Um, the alternating 1s and 0s isn't about power, it's about signal whitening. Also differential pairs. Because wires are analog and not digital.

  • Wow, sounds like something you buy at the drugstore. Yesterdays tech at tomorrows prices. Also saw a VHS copy of Harry Potter movie for $20 at my Rite Aid before they closed up shop.

  • You can get about 4 lines, maybe 6 in extreme cases, through connectors like that and the signal will not be very good. That is just enough for USB 2.0. If you wanted to get USB3 through a rotating connector, you probably would have to go optical. Say > $500 for a connector or so.

  • I've been ordering them from China for nearly a decade.
