There is a reason for USB-C extensions not to be part of the standard. They can be bothersome in the best case and dangerous in the worst.
Anybody care to sum this up for people who can’t watch videos?
This is what AI says about this video:
The video is about the dangers of using USB-C extension cords. The narrator explains that USB-C extension cords are not officially certified by the USB Implementers Forum, which means that they are not guaranteed to be safe or reliable. He also explains that USB-C extension cords can be dangerous because they can overload the power supply of the device that they are connected to. This can cause the device to overheat and even catch fire. The narrator recommends that people avoid using USB-C extension cords altogether. Here are some of the specific dangers of using USB-C extension cords:
- They can overload the power supply of the device that they are connected to.
- They can cause the device to overheat and even catch fire.
- They can degrade the performance of the device.
- They can be unreliable.
The narrator also explains that some USB-C extension cords have a label that says “USB 2.0 low speed devices can only work with one side of the ultra high rate extension cables interface.” This means that the USB 2.0 connection is only available on one side of the cable. This can be a problem if you need to connect a USB 2.0 device to the cable.
The narrator recommends that people avoid using USB-C extension cords altogether. If you must use one, he recommends that you use a high-quality cable from a reputable manufacturer. You should also make sure that the cable is rated for the power requirements of the device that you are connecting to it. Overall, this video is a helpful resource for anyone who is considering using a USB-C extension cord. It provides important information about the dangers of using these cables and how to avoid them.
As always AI doesn’t quite get it. One of the main points is that it could catch on fire and burn down your house. Plus you’ll run into other problems as well. You’re not supposed to buy extensions for USB. Buy a longer cable instead.
Jokes on you buddy. Most people can’t afford houses these days.
But yeah, if you don’t know what exactly what you’re doing, err on the side of caution
If you want a more detailed explanation, USB-C is a small connector that was designed primarily for data transfer, extended power range delivery (240w) was essentially hacked on to the standard. Electricity arcing between the contacts on the connector is the biggest challenge with this hack, since the contacts are small and very close together, which could burn out the circuit board and start fires. For EPR to work safely, there needs to be a lot of extra components on the circuit board/female connector side, which there simply isn’t enough space for on an f2m extension cable.
As for why USB-C cables are so short, it’s simply a matter of physics, carrying high speed data over larger distances would result in higher losses and requires thicker conductors and more shielding, which is why you don’t see USB4 Gen3 cables over 1 meter unless they are optical, and longer “charging cables” are only rated at USB 2.0 speeds, because more often than not they don’t even have the USB 3.x data pins on their connector.
