Do You Understand USB-C Well Enough to Confidently Pick Cables and Chargers?

With the various charger and cable deals there are always questions such as:

  • Can I use this to hook up a display?
  • Will this charger work with my device?
  • Can this be used for data transfer?
  • Will this Super Fast Charge my device?

USB-C is common across many phones, laptops, consoles and other electronic devices now.

Do you understand USB-C including data and charging to confidently buy the correct cable or charger?

    I would like to retract my last statement.

      Hmm, interesting. Yet once again, here you are commenting.

        Don't listen to him, he's just jealous of your insight in finally canvassing an opinion on this matter.

            @ihfree: It won't be as popular as next month's "If You're Eating A Sandwich, Do You Use A Small Plate or a Big Plate" but sometimes we need to look past the clicks and appreciate the art beneath.

              @CrowReally: Woah, that's a complex topic to translate into a poll. There are so many factors to consider:

              • Type of bread, how many crumbs
              • Sandwich filling
              • Size of sandwich
              • Is the sandwich cut?
              • Where are you eating the sandwich?
              • How easy is it to dispose of the plate?
              • Indoors/outdoors?
              • What is the impact on social standing?
            • +4

              @CrowReally: I think a large plate is superior, as it is better at catching the pesky crumbs.

              • @brendanm: Don't buy small plates. Only use large plates - life is now more simple.

        You have run a lot of polls . Seems quite odd.
        Is someone(OZB?) paying you?
        Do you work for OzB?
        Are you a Mod here?
        Did you fail marketing or never finish psych certificate 3 ?

            I'd like to see your proof I 'read every thread'.

      Well, I couldn't resist a look what someone who criticises threads for being mundane posts:

      Fascinating stuff, mate!

      • How do roundabouts work?
      • I don't understand cricket
      • Is this car ugly?
      • How is this font different?
      • Which form of deep-fried potato do you prefer?
      • Reddit isn't working and I didn't check the status page
      • Are you offended by a number plate?
      • I think you're confusing criticism with sarcasm and poor attempts at humour.

          Oh, you're still here… on this mundane thread. I guess you need to keep that average of 12 comments per day up somehow.

      Boy he really is a mod and a nasty one

  • Is there any advantage to a usb-C charger (C to C cable) as opposed to the older usb-A charger with an A to C cable?

    • -1

      probably voltage

    • The short answer is yes for most modern devices.

      It depends on whether the device supports charging via USB-C and what charging protocols are supported.

    • +1

      I assume you answered NO in the poll.

    • +3

      On supported devices, it's much faster.

      On other devices, it might not work at all. There is a lot of "USB-C" stuff out there that requires A chargers and A->C cables and will not charge via a USB-C adapter because the manufacturer didn't add the appropriate pulldown resistors or signalling. Sony 1000XM4s and Anbernic RG351P are such devices in my collection. The Raspberry Pi 4 was also infamously broken with higher grade USB-C cables.

      I travel with a three port A charger, a 100W dual port USB-C charger, and a bunch of cables.

      • Ha, sounds like the Universe is a real mess.

      • How can you tell which needs what? And do you mean your raspberry pi was damaged by using a particular cable/charger?

        • +1

          No RPIs damaged - just didn't work with 5A cables with e-markers. A later revision fixed the issue.

          There are a lot of articles already on what to choose. Personally, I carry:

          • 100W/USB 2.0 cable for charging
          • 100W/USB 3.1 for charging or data transfer
          • 60W/USB 2.0 for a cursed device that doesn't work with 100W cables

          For chargers, the general rule is meet or exceed the wattage of the original charger.

          • I use 100w multiport chargers around the house
          • If you have a Samsung phone, you may want a charger that supports PPS for super fast charging
          • Some devices don't support USB-C properly and still require USB-A cables. This should be documented when you buy them. For me, that's a torch or two
          • If you have a device that uses a proprietary extension, you may need a special charger(and/or cable) - eg: 130W Dell laptops, Non standard charging options eg VOOC.

    Confidentially? Well, that's not something I'm willing to share!

    In answer to your poll, yes.

    u need to set up a new website and provide this info on all cables

  • +1

    No I don't. I'm hoping that soon more devices and cables will be certified as Thunderbolt 4 instead of USB C.

    • +1

      Do you need the Thunderbolt cables? I only use them with a Thunderbolt dock.

      I generally use 2M 100W/USB2 cables for charging as I don't need data transfer and 100W covers all my devices.

      When I do need to transfer data or use displays I use a 100W/USB 3.1 cable. I generally don't use it as much as it is thicker and less flexible.

      You're on a bargain website that primarily drives consumerism. You may also notice that USB-C chargers and cables are one of the more popular categories

      Get off your high horse.

      • High horse?
        You don't need to be high on anything to spot someone taking the piss.And I missed the 'rule' about what I can/can't comment on.

    It's a mess of a standard imo. Different wattages and delivery standard (PD etc), whether the cable transfers video as well (eg lightning), needing to check both your device and charger for what wattages they accept/deliver to make sure the cable will work optimally etc

    One thing I've never been able to properly clear up is can I safely plug anything lowish power (eg a raspberry pi, mobile phone) into a high-wattage charger for say a laptop? Are charger adjusting delivery wattage based on the receiving device? I think some do but not really sure.

    I find myself doing a solid google search any time I'm about to buy a cable or charger just to make sure…

    • +3

      I concur. I’ve had to learn all of the components of the USB C cable family for work and I’m still, two years in, finding shit that shouldn’t happen.

      Better yet, half the cables out there aren’t actually capable of what they say on the box because….made in China.

    • In your research (device-specific I assume) have most or all devices had appropriate current setting on the charge circuit?

      I've so far found it to be the case with Micro USB and switching between 500mA and 1A bricks. Did a similar thing with an Acer laptop, the voltage matched and at the time didn't consider the current. I'm guessing it's max rated current…

    • +1

      Yes you can plug a device that needs 10W by example in a 60W or 100W charger, it won't blow-up the device.

    • whether the cable transfers video as well

      If you are using a thunderbolt dock, you would need a thunderbolt cable which are generally marked with a lightning symbol. For more basic display needs, a USB 3.1 cable is fine (eg: Steam Deck to portable monitor).

      One thing I've never been able to properly clear up is can I safely plug anything lowish power (eg a raspberry pi, mobile phone) into a high-wattage charger for say a laptop?

      Yes, that's fine. The device will negotiate what it needs. For almost all cases, you don't have to worry.

      I have charged earphones, phones, steam deck, and controllers with a 100W charger without issue. I've even used the Apple 140W charger which implements PD 3.1/EPR(extended power range) for these devices. This should be a non-issue with the next version of the standard as well.

      The RPI issue was a bad USB-C implementation. IIRC, it just didn't charge when used with 5A cables. 100W cables have a chip in them that says the cable can handle more current.

  • legit question what is my Samsung S21 charging cable called?

    • Pretty much any quality USB-C cable will work with the S21. If you want faster charging, you'll need a reputable 25W+ charger that supports PPS.

      IIRC, they skipped the 45W charging on the series which I believe requires an e-marked cable.

    I can confidently pick a cable off Amazon that will do the job I need.

    However, could I confidently pick one from the draw of cables I have in my office? Not a chance. Any time I need a USB-C cable for video I just buy a new one rather than spend 3 hours testing and labelling cables.

    You sure know about the OMG cable then ??? if you answered Yes
