These USB-C to Micro-USB adapters are great for your legacy devices

We're roughly two years into the major transition to USB-C as a standard port on computers and phones. It's pretty tough to buy a new high-end device today that doesn't have a USB-C port, and most new laptops have at least one USB-C ports for charging and data.

But of course we don't all refresh every device we own every year — there are still plenty of phones, tablets, and most importantly accessories we all own with Micro-USB ports. All the while, every new device we get comes with a USB-C cable in the box, and the number of old Micro-USB cables we have is decreasing.

Instead of buying new Micro-USB cables to carry around for those old devices like my Bose QC35 headphones (opens in new tab) or Anker PowerCore battery (opens in new tab), I picked up a pair of awesome USB-C to Micro-USB adapters. Nope, these aren't the super-popular adapters that go in the other direction — these little bits of plastic and metal let you use your new USB-C cables with old Micro-USB devices!

Micro-USB is still going to be around for a while — make the transition simpler.

The adapters that I've been using are from TechMatte, and are just $8 for a pair (opens in new tab). Yes it feels a little dumb to be buying new things to help me continue using old technology, but try as I might to have everything in my life be USB-C it just isn't possible right now. By spending a few bucks on these adapters, I can keep using my old Micro-USB devices without having to keep a whole Micro-USB cable around. The adapters also work for data transfers to a computer, which isn't something I necessarily expected to work.

Now I've wrapped up and stored my Micro-USB cables, swapping everything out to USB-C to use a majority of the time while I have these adapters around for the edge cases when I have to power up something old. It isn't ideal, but it's far better than the alternative — and it only cost me $8.

  • I'm pretty sure Benson said these are out of Spec, the same with female USB-C to Male USB-A adaptors. saying that, having to keep a MicroUSB charger separate for my YogaBook is a pain, so I might pick some of these up
  • Out of spec for what? Micro USB? We are converting a USB-C to micro USB.
  • The problem is that USB-C is designed for high power applications, such as laptops, which micro USB was never designed to handle. These have the potential to be dangerous if you attached a high power source to a microUSB device that could not manage it or the microUSB port itself might not be able to handle. EDIT: Actually, I think Mobile-dom's explanation was the one Benson gave. Ignore me, I might have been confused.
  • Blindfusion..... wrong. Try again bud
  • out of the USB-C spec. USB-C was designed to be bi-directional from the start, so it has the precautions in place, Micro and USB-A never where, so these adaptors allow you to create a Micro to Micro or an A-A cable which could result in something that the USB-IF or the OEM can't account for.
  • Do they have one that goes thew other way
  • Nearly all of them that are for sale go from micro USB to USB-C. These go from USB-C to micro USB. Letting us use our USB-C cables to charge tablets, speakers, battery packs, etc...
  • Yes most of these adapters go the other direction.
  • Yeah if you search 'micro usb to USB C' you will mostly see adapters that take your old micro cables and convert them up to USB C cables. This adapter is great so you don't have to carry two cables to charge gadgets with legacy ports like Bluetooth headphones or a battery pack or speaker
  • I've bought several of these little adapters on Amazon from a few different sellers. They all look to be the same quality. I've found that they start to become loose and need to be taped onto the end of the cable or they start falling off. I was constantly fidgeting with them to make a good connection.
