In recent years, Thunderbolt has become an essential part of many laptops and PCs. Developed by Intel, the Thunderbolt protocol uses USB Type-C ports to deliver very high speeds — up to 40Gbps, as of Thunderbolt 4 — that can be used to connect all kinds of peripherals. Many of the best laptops you can buy today come with Thunderbolt ports, and the accessories you can use with them range from docking stations to external GPUs, all of which can greatly expand the capabilities of your laptop.
But if you have a Thunderbolt port, how do you make the most of it? We're here to help, so we've rounded up a ton of the best Thunderbolt accessories you can buy that make use of this high bandwidth. As we've mentioned, there are docking stations and external GPUs, but some monitors and storage devices also use Thunderbolt. And, of course, you might need Thunderbolt cables, so we have some of those as well.

Best Thunderbolt accessories in 2023: Bottom line
If you're wondering if your laptop has Thunderbolt, there's something you should know first. Being a proprietary Intel technology means that Thunderbolt isn't available on almost any AMD laptop. While the technology is royalty-free, there are costs associated with delivering such high bandwidth; plus, there's a certification process that needs to be paid for, so companies often leave the feature out of cheaper laptops. You'll also find Thunderbolt support in the latest MacBook Pro 14-inch and 16-inch, even though they don't have the Thunderbolt logo next to their ports. A few more laptops also come with USB4 now, which can often use many of the features available in Thunderbolt 4.
When it comes to buying any accessory, it's always up to your personal needs, so you may or may not find value in all of these categories. Either way, Thunderbolt accessories have capabilities that far exceed most USB devices, such as giving you ultra-fast external SSDs, allowing you to play high-end games on a lightweight laptop, and powering your whole desk setup with just one port. For all of those needs, the accessories on this list will serve you very well, and you have a few options to choose from. As we've mentioned, some laptops and devices now come with USB4 ports, which can support most Thunderbolt features, but that will vary from device to device.
If you're still looking for a laptop that can make full use of these accessories, we have a list of the best Thunderbolt 4 laptops you can buy today; all will support the accessories on this list. Make sure to check out our list of the best Thunderbolt docks, too, depending on how many accessories you plan on using.
