Most of them will be incredibly fine, not harm a fly, and offer like 2x+ more value than where we were before with charging which also had lots of no-name replacement brands & hard to get $100 OEM chargers. While being completely intercompatible.

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've definitely bought a charger off Amazon that later shit the bed and the NAS device it was powering wouldn't boot. I wound up buying a whole new enclosure off of ebay before determining that the power supply went just slightly bad enough to make it power up but not successfully spin up the drives or whatever and boot. It didn't burn down my house, but it caused me way more hassle and economic cost than its price was worth.

Nas enclosure from a shitty off-brand, powersupply from a shitty off-brand. User = that usb-c standard really sucks.

Except I really like the USB-C standard.

Actually, to my surprise, the answer is YES!!

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.
