1). If I have 4 USBC devices, and 1 USBC port, how do I connect them? With previous versions I buy a $10 hub. There are literally zero options to accomplish this with Usbc ( if I am wrong I would love to know about it, this is actually a problem I have)
2). The cables. Some cables support certain data. Some certain power. There are no markings to give me any of this information at all.
...albeit it'll only do data, and won't let you do P/D or video.
My impression is that the cheap-hub product got a lot harder to make because of how much more USB-C supports, such that you need to caveat any cheap product (as I had to there), and the products that do support all the USB-C features wind up being full dock-type hubs that start at around $70.
It has its own power supply. I have a USBC 14 inch monitor and a webcam plugged into the hub, and the hub plugs into my MacBook. The hub can power my external monitor, webcam and the MacBook.
Even chargers from ALLCAPS manufacturers on amazon?
It's just absurdly epic, in my book. Pick a completely random no-name brand it and there's like 98% chance it'll do the job fine, if you want a $30 100w charger for ex. In most cases, I would not be afraid to plug it in and find out. I expect some cheap chargers indeed probably won't be able to sustain full load, but I also expect they'll shutdown fine & not harm anything. It just seems unfair to try to reach into the absolute bottom-most reaches we can find to judge, and even if we do, I think most people would be impressed & shocked how little harm is done here.
But more so, there's so many perfectly fine all-caps brands that do have thousands of reviews that seem either quite legit or mostly legit. Nekteck has a 100w gan charger you absolutely can do fine with for $40. PPS and multiport capabilities abundantly available at under $50? Can we not be impressed a bit here?
Making 20V 5A & not messing causing damage is not the worlds wildest problem, even if you are cutting every corner you can.
I was trying to consolidate my chargers into a single charging station and I didn't realize started a saga. Eventually I had to give up. While I was getting down the rabbit hole, I tested dozens of different chargers and the results were quite unexpected. Though I didn't use an oscilloscope, the usb power meters used gave almost the same results, thus I would say the results were good. The best of those were a few ~$7 ones bought from Amazon, good/fair ones were either came with mobile devices or from popular brands such as A*r or B**n(I hid the names here deliberately to avoid being taken as ads). The worst were also among the two aforementioned popular brands. For A brand, its voltage dropped to 4.8V when under load ~1.8A but it caused significant interference that the USB light's switch stopped working after powered on. B brand were even worse, voltage dropped to 4.5V when under ~1.7A load.
So literally I gave up and continue to use what I have right now, at least for now.
I have no idea why a brand new cable would behave like this but after several scary interactions on the road I stopped trusting the standard and bought a better cable.
USB-C has such a loud hate-mob after it. And it's really just not bad. It really mostly is great.
