While Thunderbolt 4 didn’t bring significant upgrades in terms of speed and features, it significantly improves our user experience and confidence when buying new Thunderbolt products. All Thunderbolt 4 products must be certified. Rest assured that your performance will be reliable no matter which Thunderbolt 4 cable you end up buying.

Thunderbolt 4 Vs. Thunderbolt 3 Cables

Buying a Thunderbolt 4 cable can improve the performance of your existing Thunderbolt 3 setup. Previously, Thunderbolt 3 was restricted to 0.5m if you wanted the full 40Gbps bandwidth. Beyond 0.5m, an active cable was required, or the bandwidth dropped to 20Gbps.

Active Thunderbolt 3 cables are great and can support 40Gbps over two meters, but there is one problem. According to 9to5Mac, active Thunderbolt 3 cables lack support for USB 3(x). When you connect a 2m Tb3 cable to a USB 3.0 or USB 3.1 device, the connection reverts to USB 2.0 speeds. Another downside is that active cables don’t support USB-C monitors.

You can solve most of the Thunderbolt 3 challenges by simply getting a Thunderbolt 4 cable. A Thunderbolt 4 cable brings support for 40Gbps and USB3x over longer distances up to 2 meters (6.56 feet). You can also connect a USB-C monitor to a long 2m Thunderbolt cable.

In addition, Thunderbolt 4 cables bring other performance improvements with support for 3,000MBps transfer speeds on compatible external drives. Unlike Thunderbolt 3, all Thunderbolt 4 cables now support up to 100W power delivery for laptop charging. Falling victim to Thunderbolt 3 cables that only support 15W charging is a thing of the past.

If you don’t have Thunderbolt 4 devices yet, investing in a Thunderbolt 4 cable for your setup can significantly improve the reliability and performance of your Thunderbolt 3 devices.

When buying a Thunderbolt 4 cable, look for a lighting logo and the number 4. Shopping made easy.

Choosing the Best Thunderbolt 4 Cables – Our Buying Guide

Thunderbolt 4 cables must be certified, so no matter which brand you end up buying, you’re always going to get the same performance and features.

All Thunderbolt 4 cables will support 40Gbps over up to 2 meters, high resolutions up to 8K, dual 4k displays, fast 3,000MBps storage speeds on compatible external drives, 100W power delivery, and all the other features in the Thunderbolt 4 Specification.

However, there are still some factors and differences that help you find just the best Thunderbolt 4 cable for your needs because w


Thunderbolt 4 supports high speeds up to 2 meters, meaning you don’t have to stress yourself on the shenanigans of active and passive cables. You’ll still get the same performance and features despite the length of the cable.

Most Thunderbolt 4 cables are available in 0.8m, which is ideal for most desk setups. Plus, shorter cables are cheap and reduce cable clutter on your desk.

If you’re building a laptop gaming setup, you can benefit more from a longer Thunderbolt 4 cable. Longer cables also give you the flexibility of arranging your desktop the way you want. You can route cables in every direction or place your devices as far as possible and still connect them to your PC.

The OWC Thunderbolt 4/USB-C Cable is the best option if looking for a longer Thunderbolt 4 cable. It is well-built and cheaper than the other options from Zikko and CalDigit.

Cable Jacket

Most companies tend to use braided cable jacket to improve the durability of cables. It works, but it also reduces the flexibility of the cable. If your setup requires bending cables to connect some devices, this is not the kind of cable you want.

Most of the Thunderbolt cables on the market come with a flexible TPE cable jacket, so you’ll be good with either of them. Although, I’ll give credit to CalDigit for their excellent build quality and measures to protect your devices from damage caused by excess power delivery.


Who does not want peace of mind when buying new stuff? It does matter if I am spending a dime, I always look for a warranty.

Most of the Thunderbolt 4 cables are backed with a warranty to cushion you against faults and damage. It can be a year or a lifetime warranty, depending on the company. It’s always good to buy a product with the best warranty and a favorable return policy.

For Thunderbolt 4 cables, OWC has the best warranty of three years.

  1. Hello Ed how are you. I have a Dell Inspiron 16 plus 7610, great laptop except one issue but maybe my fault. I tried charging it using a USB A to USB C port on my LT but nothing happened. It turns out I should perhaps use a Thunderbolt 4 cable but TB4 to TB4 cables, as you know, are not cheap. In your opinion should this cable charge my laptop?
