I hate it how we went from simple, to simpler to totally complicated regarding computer ports. "Back in the days", it was a bunch of different ports of different sizes and shapes, and each thing had its own cable that fit into that thing only, and into only port only on the back of the pc. Yes, you needed 20 cables, but things were simple. Then came the USB... one cable, one protocol for all.... except video (firewir…

But the reverse is not true: All USB PD chargers are not QC chargers. Some are, but not all. I admit this is not a huge problem because QC is fading away and it merely means that some older equipment won't charge with a newer charger, but the issue does exist.

A French octet is a byte . The b here is a bit.

I really like the idea of having distinct abbreviations for bytes/octets and bits!

We do: b for bits, B for bytes. People are just sloppy when using them.

> 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? 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…

That's one option, but not everyone has £350 to spend on cables. (Especially when next year they'll all no longer be the full-featured-est around, there will be some newer thing only newer cables do).

G-d knows I would hate to spend this much on cables and this is not a negligible amount of money for me either but I would bear this if they wouldn't change the standard every year. USB 3 persisted for long enough, I really hope this hassle with USB-C will end and the things will stabilize for some years.

That's probably indicated when the posted stated that they "...plugged it into a different USB C port..." Considering USB c != thunderbolt

Thunderbolt 3 uses the USB-C format. Headline from the official thunderbolt website: "Thunderbolt™ 3 – The USB-C That Does It All" -- https://thunderbolttechnology.net/blog/thunderbolt-3-usb-c-d... This whole sub-thread is just a really good hilarious demonstration of the whole problem, nobody has any idea how to figure out what a given cable or port will do anymore. We can't even talk about it without getting confus…

I've dealt with it too. Some USB c extenders even won't carry some signals, such as video. It's an unbelievable frustrating mess. Just because thunderbolt uses the same USB c style connector doesn't make it usb c I wouldn't think. I figured the connector itself would have its own name, such as rj45 does. But who knows with this shit show.

I believe the name of the connector is "USB-C". So that's thunderbolt over USB-C, which is what all thunderbolt 3/4 is.

The wikipedia article is both helpful and hilariously complicated:

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).

i could not charge my late 2016 pro with my huawei charger (45w)

The 2016 model will charge in sleep mode on a 30w charger, it's just glacially slow, 2-3% per hour at best. 65W seems to be the universal standard for day-to-day use with laptops.
