Finally, a clear logo showing if a cable supports 240W. The USB 40Gbps logo is fine too. Now can we also get some logos for the other speeds: 20Gbps, 10Gbps, 5Gbps, 0.4Gbps (480Mbit). Also the other (PD 2.0+) power levels: 100W, 65W, 45W, 27W, 15W. https://en.wikipedia.org/wiki/USB_hardware#USB_Power_Deliver...
These all do have distinct logos already?

Not at all - its likely they wanted to reduce support calls from people who try and charge the laptop using mobile phone and other inappropriate chargers. I use dell, Lenovo, & apple PD chargers interchangeably without issues.
You can charge a laptop with a mobile phone charger. It just charges really really slowly (or probably not at all if you're actually using it).

This is all too confusing to me. Why isn't there a mandatory (or reference) specification string that combines all the necessary, useful information in one neat package instead of countless repetitive and easily misunderstood logos? Something like (just a basic, messy example) USB-C/ / / / / /etc. I had to buy some cables recently and really couldn't pick one nor distinguish particular features at glance, and the ite…

> most people will have to guess, and will get the more expensive one “just in case” Good. The more full-features and the less underfeatured USB cables are bought and found around - the better for everyone. I don't buy/grab a USB cable "for the drive" I expect it to do the job every time I happen to need a USB cable. In fact I'd like a single ultimate USB-n-All logo to exist which would mean the cable is fully and re…
But there are crappy expensive cables, expensive cables that aren't better than cheap ones, and great cheap ones. What I'd like is a mark for servicable USB-C cables so everyone can just compete on price on that. These logos kind of solve that, but personally I'd like the threshold only being the combined certification. But at least most people can just filter on one logo and compare on that, even if they don't under…
I doubt many people ever look at the logo. For ordinary people it's just USB and "this is a shitty cabble" if it doesn't work as they expect, geeks will look for a specs table on the page/box.
The intention is obviously good and sort of addresses the problem but nowadays (even with Micro-B, not just C) I don't feel like I can trust any logo really. I have to read the specs, the comments, consider the brand reputation and buy the best cable I can find (which is a game of luck anyway) to minimize the chance it will surprise me unpleasantly.

A 2m cable with 100W charging (the highest currently, but not for long) and video using Thunderbolt 3 is £70 inc sales tax, it's also stiffer and heavier than other cables. How many of those do you plan to just have lying around for convenience? My XPS 15 already takes more power than that so has its own charger with a physical USB C connector (but also accepts standard USB C chargers with lower wattage). The next ve…
I can find cables claiming the same spec (100W, TB3, 2m) for 20-30 EUR. Less if you drop the length requirement -- 2m seems quite long, especially if you're using TB3 to connect a laptop to a display. I agree that there's a place for lower-spec cables that are cheaper and thinner.
Anyway, the 2m 40gbps cables I have are actually thinner, lighter, and more flexible than either of the 2m 5-10 gbps USB-C cables I have, or even some of the really short and cheap 5gbps cables that come bundles with SSDs. Active cables might be expensive, but at least they allow using higher gauge and/or less shielding for signal wires.

I would get 5 if I could be sure they really will work reliably with every device in every case possible and the standard won't change in a couple of months. I almost feel like buying an insurance against this bullshit.
And I don't think they can be so heavy to the point it would be relevant. I'd rather buy the hardest I can find as mass positively correlates with reliability in electronics.

Isn't charging also complicated by some fast-charge protocols? I know the phone accessory companies are always saying things like "Supports Qualcomm Quick Charge 23.45 with Sprinkles" in addition to "18 watts". I think the cables might more or less be the same, but it's still a complex ecosystem question. I have two devices with USB-C chargers. I can make a reasonable guess that the bullion-cube sized charger provide…
> On my laptop, I can apparently use a USB-C to DisplayPort cable to get 4k/60 output (while the HDMI is limited to 4k/30). But now I've got no way to charge it. I don’t know what laptop you have. DisplayPort is native to USB C cabling and the Type C connector is the modern DisplayPort connector. I have my Mac plugged into a Thunderbolt display that uses DisplayPort to display the image and also powers the computer.…
For computers with USB-C only the situation is more complicated.
Please, for the love of god, make it obvious if a USB C cable can be used as a display cable or not. One thing that absolutely blows about USB C is that they all look the same, but to connect my LG UltraFine to my GTX 2070 I had to do literally hours of research before I could find a reliable cable on Amazon that was a “bidirectional USB C DisplayPort” cable because I naively assumed that USB C was a general purpose…
I'd guess 'cost'.
