I legit have never seen the battery used at all. They often use a plug, a lightning bolt confusingly, or don't even label it at all.

You won't find these symbols on most devices though (certainly not on any macbook as the picture suggests).
By removing the symbols they were able to shave the case down 0.0003nm, making it the thinnest and lightest laptop ever.
Courage!
Stunning and brave!
It gets even better, each function of the port also needs proper support from the cable. Often cables do not support the full spec of usb to cut costs.
While the symbols in the post are often put on computers, for usb cables this is seldom done (only a few brands do).
Source: had to find a cable that supports both DP and PD to connect a portable external monitor after I lost the original cable. (1/9 cables worked)
Yes, this is incredibly annoying and it's also the reason why some USB cables cost more than others, even they may look the same superficially.
What is the difference between USA and USB?
One connects to all your devices and accesses your data, the other is a hardware standard.
exept when manufacturer don't give a fuck and print whatever or nothing next to the port. like always
TL;DR: The USB Implementers Forum is ridiculously bad at naming, symbols and communication in general. (And they don't seriously enforce any of this anyway, so don't even bother learning it.)
This is the correct answer; after the whole USB 3.2 Gen 2 2x2 (hands of blue) bullshit, I wouldn’t trust that team to name a park bench in the middle of the desert. Let alone something important and universally used.
The bench is called "Bench" (legacy name, it's actually more like a concrete slab, but at the time it was more benchy that the previous bench which was just a pile of sand).
the whole USB 3.2 Gen 2 2x2 (hands of blue) bullshit
If you're not trying to wire your own USB port you can just use the recommended names "USB SuperSpeed 20 Gbps" or "USB 20 Gbps". You don't have to be confused by technical names if you don't want to be.
The real bullshit is between your ears--you and only you can fix it.
The USB-C standard and particularly the USB PD (power delivery) is so complex it almost feels comical.
The PD standard document (freely available on usb.org) is over 800 pages long and features a lengthy part about the role of the cable alone which is mostly hidden from the user. Here's a short video about this issue: https://www.youtube.com/watch?v=6bZ0y9G-4Pc
The USB standards are just... Comically overcomplicated. And almost everything about it is optional. They need a full revamp, making it simpler and mandatory on all future ports, devices and cables.
But they won't do that, will they.
Almost everything about it needs to be optional because sometimes USB is used to charge some cheap battery powered thing and sometimes it’s used to make a backup of a harddrive and sometimes it’s charging my laptop with enough power for it to be rendering video but still have a net charge increase to the battery while also providing Ethernet, video output, and keyboard/mouse input over the same one port.
EDIT to make it more clear why the variability of USB standards is what it is, compare a modern laptop to one from 10 years ago.
The older laptop has:
- for video, an HDMI port (or the less common mini HDMI port), and perhaps a mini DP port
- an Ethernet port
- a charging plug
- possibly some FireWire ports (may or may not be the same as the mini DP port)
- USB A ports for keyboard/mouse and other random devices
The newer laptop has:
- USBC ports that can do all of the above
The perhiperals, however, don’t support all of the features. They only support the features they actually use. As long as the laptop supports all of the optional features, you don’t need to worry about it.
The is especially helpful for less technical users who may not want to know what the difference between HDMI and DisplayPort is. With a fully USBC based laptop and USBC perhipals you can just plug it in and it will work.
Of course this is all dependent on the laptop implementing all of the extra features, which is still only really true of more expensive laptops.
Thank God there's a standard for USB. And another one. And another one. And another one. And another one. And another one. And another one. And another one. And another one. And another one. And another one. And another one....
USB = Unintelligible Symbols of Bewilderment
My laptop has two USBC ports. No logos of any kind. They are Thunderbolt 4. ¯_(ツ)_/¯
Here, you've lost an arm: \
I have never seen one with SS, but maybe they removed that part in Germany.
For those that don’t know

Also don't forget the dubious AliExpress devices that have all these symbols, no data lines, Vcc at 12V and ground attached to a loose M8 nut.
Additionally, USB 3.0, 3.1 and 3.2 labels provide no information on the speed. Rather, "Gen 1" means 5Gb/s, Gen 2 means 10 and Gen 2×2 means 20Gb/s. These "Gen" labels are seldom found on products however.
So for example USB 3.2 Gen 1 is 5Gb/s while USB 3.1 Gen 2 is 10Gb/s
Every device I have just has a couple of blue ones and a couple of black ones, perhaps some orange ones and some USB-C ports, and good luck figuring out what they all can do. No symbols anywhere.
Most devices don't have theese symbols and basically say fuck you unless you know how to find the specs
Meanwhile my thumb drive:
The best I can do is 20Mbps with the curve xy = 1
I just love that in a world with Power Delivery (PD) they decided that the best way to indicate Display Port (DP) was to have an ambiguous symbol involving a P and a D.
USB keeps changing their own standard every 2 years why bother learning it.
