Best Prime Day deals on Thunderbolt docks and USB-C hubs

USB-C hubs and Thunderbolt docks use the same physical USB-C connection. A USB-C port (and USB-C hub or dongle) use a basic 10Gbps connection, while a Thunderbolt port increases the throughput to 40Gbps. Ideally, you should see a small “lightning bolt” icon signal a Thunderbolt port, while an unmarked port may be just a generic USB-C port.

Manufacturers, though, aren’t forced to label their ports. Your best bet is to haul out your laptop’s manual and check.

Thunderbolt docks will only work with a Thunderbolt connection. You can buy a USB-C hub or dongle and connect it to a Thunderbolt port, but it will only run at the 10Gbps speed.

Laptops have generally begun replacing all of the legacy ports (the boxy USB-A plug, HDMI, SD card slots, and more) with generic USB-C ports. That’s fine, but what if you have a wired printer or mouse or external SSD? You’ll need to connect it to your laptop, and you might need the right physical port connector.

If you have a fast external SSD or hard drive, the external throughput will certainly help you get the most out of your peripheral. And if you want to connect multiple displays, you’ll need a USB-C hub (and preferably a docking station) with support for two display connectors.

I use hubs and dongles interchangeably to describe the small devices that hang off your USB-C port with a short cable. A docking station is generally large and heavy enough that it will remain on your desk. Virtually all Thunderbolt devices are large enough to be considered docking stations.

You can buy USB-C docking stations that lack Thunderbolt connections, but those are a bit rarer. A docking station also usually includes a charger so you can use it instead of your laptop charger.

USB4 and Thunderbolt 4 are functionally the same. Intel refuses to certify non-Intel platforms like AMD’s Ryzen for Thunderbolt, and the new Copilot+ PCs from Microsoft powered by Qualcomm Snapdragon X Elite chips are in the same boat.

USB-C hubs work with basically anything with a USB-C port on it. Don’t worry about those at all.

Thunderbolt is backwards-compatible, so you can own a laptop with Thunderbolt 4 and connect it to a Thunderbolt 4 or Thunderbolt 3 dock without worry. It’s not forward-compatible, however. While Thunderbolt 3 and Thunderbolt 4 both transfer 40Gbps, you’re probably best to play it safe and match the specs of your port to the specs of the device.

This is the big wild card. The United States has paused its reciprocal tariffs on foreign goods until July 9, the second day of Amazon’s Prime Day deals. At that point, it’s anyone’s guess what will happen.

Many hubs and docks are made in China, which has been a prime tariff target for this administration. On the other hand, dock makers like Plugable have specifically told me that they’ve moved manufacturing out of China, too. But consider: CalDigit announced its TS4 docking station in 2022 for $359.95. Its current list price: $449.95, and it’s “on sale” at Amazon for $379.

Unfortunately, it’s become even more complicated, practically overnight. Some dock and hub makers have moved their manufacturing out of China and Taiwan to Vietnam, and the Trump administration just set a 20 percent tariff on goods imported from Vietnam, and 40 percent on goods routed through the country. It’s just not clear exactly which company makes its products in Vietnam or China, however.

There’s probably one sure answer to avoid tariffs: buy early to avoid paying the possibility of extra import tax.

While Macs adopted Thunderbolt first, some of the Apple M1 silicon couldn’t keep up with Intel Thunderbolt controllers used by Windows PCs, and the Apple MacOS experience suffered as a result. If you see a negative comment, try and determine if it’s a Windows user making it. The experience may be totally different.

Historically, yes. I check other sites, but over the past few years Amazon has consistently offered the best deals on these two product categories. Thats not always the case; Best Buy, for example, is often very competitive in Chromebooks.
