USB-C extension - pay attention to this with USB Type C cables!

Whether a USB-C extension with plug and socket or a long USB Type C cable - when buying, you should pay attention to properties such as USB generation, data transfer rate and power delivery. The latter means that the extension or the cable supplies up to 20 volts at 5 amps, i.e. 100 watts, in order to be able to quickly charge iPhone, iPad, MacBook, Nintendo Switch and Co. For the USB generation, at least USB 3.1 Gen 1, or even better Gen 2. The data transfer rate should be up to 10 GBit / s. This not only ensures you a good charging cable, but also a useful aid for data exchange, for video transmission in 4K and more.

A USB-C extension or a USB Type C cable should offer Power Delivery (PD), have at least USB 3.1 Gen 2 for up to 10 GBit / s and have a usable length. Here you will find good and very good rated examples.

USB-C extension for bridging longer distances

As already described, what I mean by an extension is a cable with a plug (male) and socket (female). As with an extension cable for powering electronic devices, the USB-C extension should have some quality features. Here again briefly listed my requirements for the accessories for iPhone, MacBook, Switch and Co .:

  • As possible USB Power Delivery (PD) with 100 W (20 V with 5 A)
  • A useful length of 0,5 to 2 meters
  • Data transfer of at least 10 GBit / s (USB 3.1 Gen 2)
  • By no means only USB 2.0 (which you can sometimes find at AmazonBasics), because the data is transferred very slowly
  • As robust as possible, so that you don't have to buy several times

Examples of good and very good USB Type C extension cables

On Amazon, I found four examples of good to very good rated USB Type C extension cables that meet some or all of the requirements listed. Here is an overview with which you can find the right USB-C extension for your end devices, chargers, hard drives and monitors:

USB-C cable with USB 3.2, Power Delivery and up to 3 m in length

When the requirements listed above are met, cables and extensions are already Thunderbolt 3 quality and can be used on the MacBook Pro, for example, for data transfer as well as for charging the battery or transferring video signals with 4K resolution and 60 Hz frame rate. In addition to an extension with a plug and socket, there are also cables with two plugs, which are also of this quality and can also be longer. Because a plug connection is always a weak point - not only because of the purely mechanical connection, but also in terms of its functionality.

That's why I would tend not to use a USB-C extension, but rather a longer cable. A USB-C cable with 100 Watt USB PD, USB 3.1 Gen 2 and thus 10 GBit/s data transmission and a length of 1, 2 or 3 meters are available from CABLETEX, for example. Of course, these cables can be used on Thunderbolt 3 ports and other outputs and inputs to also output 4K video at 60 fps transferred to. The price varies depending on the length at 14,95 to 29,95 euros. The cables are also braided, which makes them resistant and prevents cable breaks. What do you think? Feel free to leave a comment;)
