Suck it micro USB, mini USB, and lightning! 🪫🔋
USB-C doesn’t have speeds, it’s just a connector type. USB 1, 2, 3-3.2, 4 etc. is the protocol responsible for speed. You can have a USB-C connector with any implementation (except maybe USB 1). It can even do DisplayPort stuff.
So for USB-C to become irrelevant we need to come up with a better connector form factor. Which is unlikely to happen soon. But also, same thing happened with USB-B Micro connector (colloquially called micro USB), it was designated as a standard (but Apple managed to get an exemption) and manufacturers had no issues moving to a better connector, which is USB-C.
On the downside, you can’t tell what the port supports by just looking at it.
Even with this graphic, I still don’t know what they support. Is circle-20 also 20gbps? What is the speed when there’s no number? Do the non-DP ones not support displays at all? And there appears to be no such thing as USB4-DP?
And good luck getting your grandmother to identify any of this over the phone. “Is it marked SS-subway diagram-20, or circle-20-subwaydiagram? Yes it’s etched gray on slightly different gray, go put on your strongest glasses first, grandma.”
My phone doesn’t have any kind of marking anywhere on it so I’m guessing it’s USB DP
Was wondering about thunderbolt. Found this, which I interpret as
usb 4 40 = thunderbolt 4
Very much in favor of the mag induction charging! That should be a standard for wall plugs as well
MagSafe/Qi2 is definitely convenient, but you have to be wary of its downsides. 2 of which are:
- wireless induction wastes a good amount of energy being transferred
- wireless induction additionally heats up the battery and reduces its lifespan
But the good news is, it’s basically the defacto standard. Since Apple opened up this standard it pretty much killed all the competition. The adoption is expected to increase in the coming years.
I wouldn’t have even known what to google to learn this. Thanks for sharing! I actually love the C form factor I didn’t realize that was kinda what made it C and not what it could do. I appreciate your response.
Wikipedia is a good resource
What I don’t understand is what was wrong with mini-USB.
Too thick? Just why do people want a portable computer to be thinner that their wallet, or their notebook, or their damned pen, or that Snickers bar in their pocket which nobody made thinner. Who the hell told them that “miniaturization being the future of tech” has anything to do with the box inside which that tech is mounted being just a bit thinner? I mean, were it thin enough to put computers into printed magazine pages, maybe (I think I’ve read that someone did this, with a computer kinda as powerful as ZX Spectrum). Why do they specifically need it? Not to appear “modern”, but really?
The question is, because for me personally mini-USB was very convenient. It held well, was easy enough to stick the right way (and not ruin it trying to stick it the wrong way).
Now, I guess USB-C is fine if it can do the same and go both ways. I actually like it, except RPi 4 is the only device I have needing it.
It’s just … how can one try so many connector types for one group of standards?..
If I were to guess, it would be the additional pins. USB-C PD is capable of decent power transfer while also having enough data transfer capability simultaneously. USB-C docks are a good example, seeing that you can hook up a display, charger, other USB devices, ethernet, etc and have it all go through a single cable and (compact, convenient) connector. The reversibility is an added bonus
Mini-USB sucked, big time. Not so bad as micro, but yea it was bad.
The main advantage of C over all previous versions is that it’s reversible, you can’t plug it in wrong. The shape is also… “flat”?, so it’s easier to fit into the socket, mini had that wavy like thing going on.
My data source is my small kid: he’s broken 3 (and counting…) usb-mini micro connectors by tugging the charging PS4 controllers, and he has to ask me to connect the cable to charge them, he’s unable to do it himself yet. With his tablet, 0 usb-c connectors broken and he can plug it in himself.
I think you guys are taking about micro USB. PS4 controllers have micro, PS3 controllers had mini USB.
USB micro (not sure if you’re getting micro confused with mini, but doesn’t really matter) only supported data transfer, not video transfer (like HDMI). Some USB-C ports are data only, but it theoretically supports more than USB micro was ever capable of.
For example you can buy a USB-C to HDMI cable for a few dollars, which could theoretically plug your phone directly into your TV (if your phone supports that). But a USB micro to HDMI cable was called an “MHL adapter” and was expensive and only worked on specific MHL capable phones like this one. It has a separate box that requires its own power cord in order to work, it’s not just a simple cable. USB-C should, in theory, eliminate the need for such a thing.
At the risk of sounding like Blizzard, don’t you have a phone? Even my previous phone, Galaxy S8 had USB-C. Or do you have an old iPhone?
Pretty much all electronics that came out in the past 4 years use USB-C. Just an example, here’s a non-exhaustive list of things that I charge with C:
- MacBook (2020)
- iPad (2018)
- Galaxy S10e (2019)
- Steam Deck (2022)
- Nintendo Switch (2017)
- Kindle (2020)
All of these are, on average, at least 4 years old. So I’m pretty sure the average consumer has already switched to primarily USB-C
