you ought to be a scientist. have a nice day.

They don't work the same. You won't put your hand in an active power socket while you can safely touch both ends of a 12V battery. Super vooc @50W is only 10V it is relatively safe. What are you being concerned about? Afraid of what you really don't know? It is either your example is just poorly written or you're just trying to reason out on a topic you know nothing about. This is the internet and ignorance is now a choice. If you want to learn about basic electricity, you can but you just won't.
Cable fraying is wear and tear or manufacturing defect. That's physical damage on the cable, an electrical fault is different because it will fail the very first time you use it.
Concerned about being electrocuted? Learn about ground fault on AC systems. You'll know what I meant. Do you know why chargers or power socket have third prong? Yeah, search it. If your socket is just 2 prong, I really do hope that it has an internal ground system because at that point, the issue is with your poorly designed socket. Basically, any device with bare metal part will zap you no matter which charging tech you use. But at this point, I'd guess you won't be able to comprehend that. lol.
You keep on barking on the wrong tree and trying to reason out via disjoint samples. You don't have the capability to know where faults are on electrical systems but you keep doing so pointing at the wrong sources. It just shows how incompetent you are in this topic. There, I said it. Happy now? lol.

while any fast charge tech does have issues, higher amps are inherently more dangerous than higher voltage. you can receive 30,000 volts on your hand but nothing will happen if there are no amps. tasers are high voltage with low amps for that reason and even then they end up killing people with a bad heart or a pacemaker. its the amps that matter.
that's my point about vooc tech. i hope you know the difference.
as to your other points, incl the oneplus point, it looks like you didn't bother reading/comprehending so i'd rather not waste my time. reg. cable fraying, looks like you haven't met half the apple users in the world and a sizeable population of android users too (typically those using less expensive phones).
see, end of the day, you aren't gonna change your mind as you are reading requirements in theory, but don't have an idea of the spurious practices cheaper manufacturers follow - even the better ones aren't perfect. huawei is supposedly so amazing but they messed up the nexus 6P's wiring. similarly i'm not gonna change my mind either, rather i don't ~need to, as i've seen how QC people just tick boxes without actually doing extensive checks. i've worked in Chinese factories before as part of my work.
i stand by what i said - vooc is promising but is equally more dangerous.
so whatever rocks your boat man. you wanna have the last word, please do. i'm done.

It has been proven but that phone was from 2015, an issue with Qualcomm tech where USB PD wasn't implemented yet. Qualcomm has to use their own standard for their quick-charge (QC) that time for their fast charging implementation because that's the only way possible.

It isn't, it simply disabled because there's no handshake being done on non-compliant peripheral. Your arguments were focused more on VOOC implementation as being the issue/faulty while pointing out examples that CAN happen on any charging technology available. And that's where you're wrong, you're barking at the wrong tree all this time.
Oneplus USB cable not truly fast charging? What's Warp charge then? Lol. Poor quality aside (which are also happens on other manufacturers not just OP), not all cables will be compatible with each and every high-power fast-charging mode available. If they charge slow using the cable, then it's already using the default fallback charging speed which is the slowest (handshake failed for the fast charging mode). Short circuit on the other hand is a quality-control issue and is not an issue of VOOC for example.
Tell everyone to make their own? That's more of your thing, asking someone to start a website here is not a good idea isn't it? lol.
Half of them does not understand USB C spec? It's their problem. RTFM, at the very least. Oh, no one reads that? It's the person's issue, not the manufacturer.
If only you knew how these systems works, you'll know what I meant. I already know what USB-C issues are, they're even present in the world of single board computers and I know too well about them after dealing with them for months in the forum and by checking the type c schematics. But these have fallbacks which is slow charging, that's it and anything related to short-circuit is a quality-control issue which is a manufacturing defect, not an issue of the fast charging tech, I really do hope that you know the difference.

quality control, yeah right.
it seems you imagine 'brands' are perfect, when more often than not, they aren't. and with the new stringent requirements in usb-c form unlike the older legacy forms, there is far more room for error.
scoring brownie points online to sound 'politically correct' doesn't change what's real - but yeah, keep thinking whatever you wish.

my comments to this point merely stated the fact that assuming the phone's power controller is correctly designed, the dangers a regular customer would have to face are in the cable side or the adaptor/powerbank side. this means vooc tech ought to have more concerns for a regular customer who does not know what to look at when buying a replacement or spare item.
you state after-market and third-party products are not a problem, however even a 'first-party' product, a usb-c cable released by oneplus, was of poor quality and not truly fast-charging compatible, flouting the usb-c design norms.
yes, please go and tell that to everyone to make their own thing. you expect the regular customer to figure out technical intricacies when most aren't even sure of the difference between ram and rom. lol.
half of them don't even understand the usb-c spec and the dangers an improper cable poses to them and their device.
a website only for me? not expecting any visitor eh? well whatever. not like i care either way. there are decent and more informed people out there like Benson or Nathan, who know the risks of badly designed power tech and honestly review even individual cables from a variety of brands for the sake of others, instead of doggedly supporting something 'just because'. go figure.

A dumb-charger can easily regulate because they only give power to whatever the phone is currently asking, the phone is the master, the charger is just a slave. I can basically make a dumb charger using a 5V5A rated regulator and that will charge my 5V2A phone at 5V2A because that's what my phone is rated. Also do you remember handshake? It requires both parties to aggree. In this example, my phone is capable charging up to 27W, my basic diy charger is not compatible with higher protocols and the phone will just use the smallest power that it's rated for which is 10W.
Using frayed wire is a blunder for the user. That's an obvious disregard for safety from the user's side. No matter which device is being used (noth just phones).
It is not a problem for me if I know a lot about electronics. That's my hobby. It's not that hard for me to create a powerbank for my phone right now if I wanted to. The appropriate question is that, you, how much do you know about HV and HC charging and specifically Quick Charge, USB PD and OPPO's VOOC? It's not that hard to learn, documentations are out there in the open. If I have knowledge about this subject matter, would that be an asset in itself? lol.
I can easily make a website for you but that would be unnecessary. Do your own homework. It's not that hard.

with an original charger/brick, we can be reasonably sure of the handshake (and even then, Benson Leung) but that's not the case with a replacement charger/brick, and that is my point here. can anyone absolutely guarantee that an after market third party charger/brick would operate without flouting the requirements?
further, your assumption would be right if the power regulators of those phones in question are designed to handle the high amps or high volts properly. if the charger is designed to be 'smart' enough to figure that out, great, otherwise its a nice formula for getting a nice toast.
i've seen burned out wires from 'currently popular brands' and i regularly see idiots using frayed cables, so yeah, i'm sure its all fine.
actually i'm mildly miffed that you speak as if you have personally designed every charger/brick out there. the tech may be 'supposed' to act in a specific manner but would you personally guarantee that the manufacturers selling cheap phones did not cut costs here and there? if so, go ahead and start a website selling those personally guaranteed stuff promising insurance/monetary guarantees and i'll buy your stuff and promote your website with my own cost.
stobs, 22 Jul 2020any non-VOOC charger/brick would fall under that category. with high current, you need a high ... moreAll these fast charging spec requires a handshake before doing the fast charge and that requires cable detection which has been being done for years on both high voltage and high current charging tech. If the cable is not thick enough, it will fail at handshake on Super VOOC as well as it will fail on lower voltage high-current spec of Quick Charge (ie 5V 3A). Super vooc or vooc has atleast 5V/2A (10W) fallback same as with Quick Charge. The 50W spec for example is not absolute. Fast USB chargers have more than one output. If you have a cable burned on a super vooc charger will also burn on QC or USB PD, because the only fault that these systems could fail that hard is an obvious short-circuit. Not because of thin wires inside of the cheap cable.
Current mismatch is also not a point of failure compared to a voltage mismatch. For instance, a smartphone with charge rating of 5V1A can be charged using a charger with 5V5A, keeping voltage the same is the most crucial because current only shows the max capability of the charger, the smartphone will just get what it can consume during charge which is 1A. If a thinner cable is introduced, the smartphone will just receive lesser than 1A. I don't know where did you get your points toward your fear of super vooc failing hard but I'd always associate fear with the user knowledge, or the lack thereof regarding basic electricity/electronics basics.

also, though some say there's no extra pin in VOOC cables, there does seem to be something that identifies a cable as a VOOC cable vs a standard USB cable, as well as whether the receiving device is a VOOC compatible device vs a regular device. if the replacement cable is not properly designed or if the replacement charger/brick is not properly configured, that will cause a variety of problems, the least of which is cable burn.
btw, major phone manufacturers aren't the only sellers of fast charging bricks (those fellas that are 'major' today were not close to the term 3 years back) and people don't buy only the products of major manufacturers either. there are a lot of duplicate chinese products of duplicate chinese products on the market (meta), and people who gravitate towards cheaper phones will naturally tend to gravitate towards cheaper chargers/cables/bricks etc.
that said, as long as you stick to the official/authorised cable + brick/charger and don't do something dumb, you should be fine.

also, it is technically safer for humans to receive higher voltage with lesser amps rather than higher amps with lesser voltage. even a seemingly tiny increase in amps has a higher likelihood of killing someone.
therefore, a frayed cable with VOOC tech is a higher electrical shock risk than a frayed cable with regular USB/other fast charging tech.
in other words, apple should never implement it since their cable quality is terrible (though the pin itself is awesome).
also applies to most humans who don't change their frayed usb cables.
