  • Great for keeping smartphones and tablets topped up
  • Best for 12v USB adapters and in-car USB ports

Why would you need USB to USB-C adapters? USB chargers are a ubiquitous feature of modern life, especially in the world of in-car entertainment. It’s a safe bet that your bedside draw is a tangle of cables, each a reminder of yet another piece of tech purchased that can charge via USB. Headphones, personal tablets, e-readers, smartphones, and cameras are just a few of the products we all need to keep powered up.

It turns out that manufacturers have clocked that most of us have eight or more USB cables to our name, so they’ve stopped being so generous with their cables. When they are included with a purchase, you’ll often find that they are too short to be of any practical use. This trend has also coincided with the dawn of the super-quick charging USB-C connection, meaning that lots of us are left without adequate USB-C charging cables but an abundance of older USB types. 

Luckily, there’s a way to make use of the older, square box-style USBs you’ve got knocking around. Technically called USB Type-A, these older USB formats are still usable with the help of a USB to USB-C adapter, so you can keep your phone or car journey tablet charged. These adapters are also handy for anyone whose car comes fitted with a USB Type-A port, allowing the port to be changed to USB-C. They can also be used by anyone with a 12v USB adapter who doesn’t fancy having to shell out for a second. And now that Apple has introduced a USB-C port for the iPhone 15 (ok, so you might have a few redundant lightning cables), it opens up a whole new realm of compatibility with other devices. So let’s have a look at some of the best USB to USB-C adapters.

The best USB-to-USB-C adapters 

Best USB to USB-C cable
Price: £8.99
Cutting out the middleman, Anker’s cable lets you get power and data passing between USB and USB-C ports with ease. What’s more, as the USB Type-A connection is generation 3.1, you can still enjoy all the benefits of USB-C – fast recharging is the best and most applicable for when you’re driving and using a smartphone as a sat-nav. At 1.8m, it’s got plenty of lengths to work with your situation, too.

Pros

  • All the benefits of USB-C
  • Reliable
  • Braided for added protection

Cons

  • Cable can be quite stiff to manoeuvre or route
Best USB to USB-C adapter

Rrp: £8.49

Price: £6.70
This UGREEN is the only true ‘convertor’ in our list, and that’s because we think a cable that does it for you is the easiest way. However, if you own an iPhone, then you’ve probably got a USB-C to Lightning cable. This adapter will let you use the manufacturer-provided cable in your car. If you’re somewhat of a tech-head elsewhere in your life, it’s also handy to have on a keychain in case you need to hook up to a laptop. The data handled here does drop from 10Gbit/s to 5Gbit/s, but that’s more than fine for document transfers.

Pros

  • Let’s you use already-owned USB-C cables
  • Versatile and well-made
  • A decent data rate for tech use

Cons

  • Some cables do the job all-in-one

Best USB-C cable for travelling with a group

Rrp: £8.99

Price: £6.99
Like our favourite Anker recommendation above, these two packs from Anker are a cable and convertor all in one. Though the cables are not braided, and the older USB Type-A generation does limit charging time, the length does mean that they can reach the back of a car, keeping a teen’s smartphone or kid’s tablet topped up on the way to family holidays.

Pros

  • Very long length
  • Two-pack

Cons

  • Limited charging speeds
One of the cheapest ways to convert USB connections to USB-C, these three packs do come with a compromise. The USB Type-A 2.0 connection doesn’t have very good power or data throughput, so you’re losing all the benefits of USB-C. However, if you just need to keep something trickle-charging as you’re driving around, these will let you do that.

Pros

  • Affordable
  • Three pack

Cons

  • Blocks most USB-C benefits
Best for flexibility in tight spaces
Price: £6.99
This Ugreen USB C to USB Adaptor features full super speed data transfer up to 5Gbps, more than adequate for most in-car entertainment purposes, and ideal for transferring files, movies, and songs in seconds. There's a built-in 10cm cable, which is enough to allow some flexibility but not to clutter up your dash or console.

Pros

  • 10cm cable for flexibility
  • Speedy

Cons

  • Cable can be a bit stiff

FAQS

Why USB-C? 

USB-C is a notable step up from USB Type-A. It’s a cable that is much more capable of carrying power to a device, offering a full charge 20 per cent faster than the old-style USB. While this is great for keeping your smartphone topped up while driving around town, the cable also impresses with data transfer rates, hitting up to 10Gbit/s. If you like to keep your phone charged while on the move, make sure to keep it safe and secure with car phone holders.

What devices use USB-C? 

USB-C is widely adopted. Android smartphones, Apple MacBooks, Nintendo Switch consoles, e-readers and wireless earphones are a few examples of products that universally use USB-C connections. While the Apple iPhone doesn’t currently use a USB-C connection – opting for its patented Lightning cable – the cable provided with the iPhone does connect to USB-C ports. Given the upcoming European regulations, even Apple iPhones should soon be moving over to USB-C. Fancy upgrading to a wireless phone charger? We’ve ranked our favourites.

The universality of USB-C is a great thing. It simplifies life for consumers lives, helping them reduce the number of converters, adapters and plugs that they need to contend with. It’s for this reason that we hope that the USB to USB-C adapters that we are covering in this article will be among the last of their kind.
