Comment on Realized 99% of all my chargers are USB-C. This can only mean one thing. New USB bout to drop!
rumba@lemmy.zip 2 days agoWell, that covers my phone, but then 45 watts won’t run my laptop, and if I plug in my phone and my laptop, they only get 22 watts each.
Then the cable: Can it be used for data transmission? What speeds does it cover? Will it transmit data through a DisplayPort or HDMI? If I unplug it from the power and plug it into the USB-C on my monitor, will I get video?
There are so many features, and it’s not like you can just go ohh I’ll get this USB-4_g cable and know what it does. Even the webpage for the Rundhult has no mention of what features are supported other than 100w.
The whole spec is complicated AF. You could spend $100 on a brick/cable that can do either 100W or high speed, but if you only need part of the equation, you can spend $30 on a brick and cable. What they support is almost never enumerated, even on the packaging.

Your laptop will charge at 45W. Easy!
Cable will work for data at usb 2.0, as it says on the packaging. So it won´t work for video alt modes. Easy!
My monitor has an input cable that allows for maximum video resolution and maximum power delivery. I never need to take it out. Easy!

Which cable are you talking about? This one supports data and mentions nothing about alt modes. ikea.com/…/rundhult-usb-c-to-usb-c-black-white-20…

The one that came with my monitor. Easy!
If I ever need a new one for such an extremely specific task, I´ll make sure to spend a few minutes to make sure I buy the right one. Takes a minute, but easy!
The Ikea one says it only supports 480Mbps, so that´s a no-no for video. Sad, but easy!

lol, no it’s not easy. You saying “easy” doesn’t mean it is in any sense of the word. Like the person you’ve been responding to before said, usb c can support many things and not support others. For example, USB C cables can literally be unidirectional! That sure isn’t listed because it’s assumed to work bidirectionally, but it’s not a requirement. I literally have a unidirectional usb c cable in fact.
Just cause it says 480 doesn’t mean jack when
You weren’t talking about this cable originally, you were making a claim about a cable that literally wasn’t mentioned in the article. I gave an example of a cable that directly disproved your comment in a facetious manner.
No consumer should be expected to know usb c standards (that’s literally the point of this conversation)
480 Mbps has nothing to do with supporting video. This Reddit thread explains it way better than I can, but support for a feature in the cable has absolutely nothing to do with data transfer rate. www.reddit.com/r/UsbCHardware/…/j5dohy5/

So what happens when your laptop is pulling more than 22w?
Let’s say your cable is 5G. Guess what, that doesn’t mean it supports display port or thunderbolt.
These cables all have ID chips in them that tell the systems what they do and don’t support. 1 they just can’t be bothered to put it on the packaging, 2 a lot of the cheapest Chinese cables have their chips set incorrectly.
The one cable for all solutions problem is a great idea. They could just standardize on a 240 watt 40/60 cable and sell it everywhere that would be great. Hell, I’d be satisfied if there were two cables, 240/5 with black connectors and a 65/60 with white connectors.

Then you need a more powerful charger!
If you really keep tumbling into these kind of situations, you need to a) read up on what you buy or b) get advice from a trusted seller. Easy!
