Hi,
I've read some threads here about charging the S3, but not all is clear to me. I would appreciate some explanation:
1) I've read that the stock chargers output 1A. However, on the charger I got with my S3 it's written "output: 5V 0.7A". So do you think I somehow got a wrong charger?
2) I want to buy a car charger for the S3. There are many generic car chargers in ebay, some of then output 2A current. What is the maximum current allowed for the S3? I couldn't find this number in my S3 manual or on the phone itself. Will a charger of 2A cause harm to my phone? or to the battery? or to both?
Thanks in advance!
bump... does anyone know?
My charger output states .05v=1.0a.
As for what aftermarket charger to buy, I would stay away from chargers with more output than the official for 'peace of mind that my charger's specifications are the same as the official charger that came with the phone' reasons.
Cheers
Generally wall chargers output 1000mA (1A) and USB ports 500mA (0.5A)
You do not want to purchase anything that goes above 1000mA

I attach a picture of the adapter I got with my S3.
It says 0.7A on it, while it appears that other have one with 1A.
Did they con me with this adapter?
And regarding the maximum current allowed: do you think an adapter of 1.2A might harm the S3?
Do not know where your S3 come from but this charger is not made For S3 but for S2!
I just checked the model number:
S3 charger: ETAOU81EBE
S2 charger: ETAOU10EBE (like yours)
And there is no cable on the S3 charger, it use the USB cable
Thank you for this!
I don't get it. The charger was inside the S3 box and looked original. Damn!
I think the store I bought from import their S3 from Germany, since it came with Vodafone German stock ROM. Is it possible that this is the charger they sell on German vodafon? Or perhaps the store switched it for some reason?
Mine also come from my carrier: french vodafone
Was your S3 box sealed?

Hi,
Background - I am an electronic engineer and have designed power supplies.
The Amp rating on a power supply is it's maximum capability to deliver power. The Voltage is the 'force' that it can push electrons through the device, this is the important one to have correct. So a 5V 300A Power supply will not charge your S3 any quicker than a 5V 1A power supply.
Get yourself a 1A car charger and you'll be fine. Depending on how the data pins on that charger are configured it'll be recognised as either a fast or slow charger but it will be fine in any case.
So, according to what you say, there should be not problem to use a 5V 2A charger on the S3?
The charger cannot accidentally push too much current to the device?
No. The phone limits the Amp the battery can get.
It simply won't go above 0.5 or 1Amp depending on what resistor is coded between the data pins (the 2 middle pins on the normal USB-plug)
(Note that this does not extend to all devices. E.g. cheap chinese toys and their batteries may not have any current limter, connecting them to "too powerful" chargers will result in damages or potential blow-up of the battery. The same applies to batteries without any electronic such as car batteries which can overheat and "cook")
I bought S3 in Germany 1.0A, there is a date on the charger:18.05.2012

Hi burmo,
An interesting concept. I have no clue in these things but what you say is not clear to me "all the way".
Charging my i93100 phone with 5.0V 3.1A will do no harm because it won't "push" more than 1A anyway?
And who is "responsible" for controlling this "push" the charger/battery/phone?
Does it work the same for Car chargers?
Thanks a lot,
Izik

so i have been wondering about this as well because i am currently building a custom charger for my s3 that charges the battery without having to plug into the charging port. i have redirected wires from the wireless charging port to metal tabs i have place on the back of my phone. it is a "drop in charger".
Anyway i have tested the charger that came with my phone. I also have the samsung stock charger that say the output is .7amp but after testing it with mutimeter, i have found that the output is actually 1.2 amps. As for max charging amps, I am not sure. I have tested several chargers. The new S4 charger puts out 2.34amps and i have not found any problem charging my s3 with it.

As far as I know the phone limits it so as you've found yes you will be fine
My original S3 charger is 5v 1.0amp
My original S3 charger is 5v 1.0amp. It was bought in Thailand with the phone.
I agree with burmo an advanced phone will have a current limiter as part of its circuit, however I prefer not to rely on it and not to exceed the manufacturer volt/amp recommendation.
The phone controls the current. In custom kernels (Boeffla and so on) you can change the target current. The phone has a protection built in, if the voltage is unstable (drops to much) it lowers the current untill the voltage is stable.
A HTC One charger I sometimes use (0,7A rated) only delivers 0,8A. A aftermarket charger I own (1,0A rated) is fine delivering 1,2A (modified target current, not stock). These charging currents can be read by various apps.
Get yourself a 1,0A rated charger and speed up your charging time.

Seconded the post above being an electronic engineer as wel.
Voltage should be exactly the same as you need, but this will always be the case for a USB charger.
Current should just be enough or more.
The charging current is dictated my your phone and not - and I repeat - NOT by your charger!
mine rates at 1A
What external battery will work with the Galaxy S8 considering it has USB C now? There was a mess awhile back with people arguing over what was safe and what isn't. Will popular external battery brands such as Anker PowerCore+ be safe or work with the new Galaxy S8?
I've never had a problem with any of my external batteries and any of my phones. I think if you stick with a decent brand, you'll be ok. Just don't use those crappy ones you get from gas stations or whatever.
What's really important is the usb C cable you gonna use, i've been using external batteries with my lg g5 without any issue so far because i keep using the og cable . Don't use any cheap usb C cable or it might kill your device.

I have used my Anker Powercore+ 10050 and Powercore 20100 with my Galaxy S7, S6, Pixel, Nexus 5x, Nexus 6P, Lumia 950, HP Elite X3, Note 5, and my iPhone 6, 6s and iPad Air2 and Air devices just fine. I imagine the S8 shouldn't be a problem.
For my devices that use USB-C, I got an Anker "USB-C to USB 3.0" 3ft that is on their web site (ordered via Amazon). From what I understand using a USB-A to USB-C cable doesn't allow for "fast charging." But it does allow me to charge my Pixel, Nexus, Elite X3, etc at "standard rate" just fine.
I'm not sure what "standard" the S8 is supposed to use for "fast charging" . I don't know if it will be QC2.0, QC3.0, QC4.0, or the same USB-C standard that the Pixel, HP Elite X3, Nexus 5x, etc support. So I don't know if I'll need to upgrade my battery pack to one with USB-C port on it, like the PowerCore+ 20100 USB-C Port.

I had purchased one of these a while ago for an older phone. You can just reuse the old ones- no need to buy a newer one.
Don't buy sketchy Type-Cs. If you are unsure, Anker is always reliable.
Does anybody already know any battery case that's already out?? Cheers

If it's anything like the note 7, any battery pack that has a USB A port and supports fast charging will support fast charging on the Gs8. The pixel uses type C power delivery which is really different from Quick Charge. I used the same battery pack from my note 5 but using a type C cable and had no issues with fast charge. Another thing to remember is that if you have a crappy cable, no fast charger will make it charge fast. The oem cable is always a good place to start.

But that is just it... *IF* the S8/S8+ use QuickCharge 2.0 or 3.0 over USB-C, then sure, any battery pack with a USB-A port that supports QC2/3 should fast charge the S8/S8+ with a quality USB-A to USB-C cable.
But if the S8/S8+ instead uses the USB-C fast charge standard that the Pixel, Nexus 6P, etc use (which is NOT QC2.0/3.0) then its another matter. A Battery Pack with USB-A ports likely wont fast charge the S8/S8+.
When I initially posted, I saw nothing speaking of which spec the S8/S8+ uses. I have since seen a few unboxing videos on Youtube which show the S8/S8+ wall charger. It appears to be a QC2 compatible, with the same specs (output voltage/current) as the wall charger that comes with the Galaxy S7. So if that is correct, then yes, any battery pack that supports QC2 should continue quick charging the GS8/S8+ . And the question now becomes... Will the USB-C port on something like this RAVpower -> https://www.amazon.com/gp/product/B019IFIJW8/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1 or other USB-C based chargers (wall, car, or battery pack) "Fast Charge" the S8/S8+?

What's you're talking about is type C power delivery (which is what the pixel supports and uses for fast charge if I'm not mistaken.) QC 2/3 is not compatible with type c power delivery. QC 4 has the ability to use both, but not QC 2 (which is what it looks like the gs8 uses). So to answer your question, I doubt it. I think the voltage on type c can handle more, so it may charge faster than micro USB, but not as fast as Quick Charge. If you just need a new battery, I'd look for one with type C input/output as well as quick charge 3 and USB power delivery. This article helped a lot when I was looking for a battery pack for the Note 7.

Thank your for the link, that will be handy for a few of my friends, I might have even read that a while back too(it looks familiar, but I can't recall). I understand the differences. I was trying to answer the OP's question at the time saying I wasn't sure what standard over USB-C the S8/S8+ was using.. so I didn't know which batteries would "fast charge" the S8/S8+ but they all should work to charge at some rate..
I'm set with batteries.. I already have that RAV (since I have a Pixel, Nexus 6P, Nexus 5X, HP Elite X3, Lumia 950, Huawei p9 for work which all use USB-C), and a few Anker and Aukey in various sizes/capacities that support 5V/2.4A and QC2/3 for my Samsung and apple phones/tablets.
As far as I can tell, with USB-C "Power Delivery" we don't need quickcharge anymore. PD is the new industry standard equivalent of QC, is being pushed by Google, is the only one fully and officially compatible with the USB-C spec and will likely be REQUIRED in future versions of android (https://arstechnica.co.uk/gadgets/2...mm-quick-charge-with-android-incompatibility/). There is no longer any reason to be looking for Quick Charge unless you want to continue to use your existing equipment. What you should be looking for is Power Delivery compatible equipment and cables instead, as they will be future proof. Once Google force PD to be used in future versions of android, QuickCharge will die (thankfully) and we can have a single charging spec that everyone can have guaranteed compatibility with without paying royalties to Qualcomm. Frankly its great news that the S8 has PD (although I am not entirely sure if it is actually using it for fast charging or not), it means I can buy PD gear without having to go out and buy QC stuff thatll probably be obsolete in a year or so.

Where did you see that the gs8 has USB power delivery? Also I dont see quick charge going away especially since quick charge 4.0 supports USB power delivery. http://www.anandtech.com/show/10846/qualcomm-announces-quick-charge-4
I would love to see a single standard adopted and Google forcing oems to use USB-PD is awesome, I don't seen quick charge giving up that easy.

I read in a couple of places but nothing official and I am not sure if it applied to the SD835 or the Exynos as well, I would imagine both support it but whether Samsung has enabled it is perhaps another matter, something we could do with finding out! Samsung as clear as ever saying it has "fast charging" which means absolutely nothing. It obviously charges quickly, but what bluddy charging standard is it using when it does it!? I have heard that it only has QC2.0 not 3.0 or 4.0, which isn't particularly fast so I suspect it might be using PD for its max speeds.
It's really starting to piss me off. These devices are out there, quite a few people now have them and we still have unanswered BASIC questions like what charging method is it using and does it support UHS-II or UHS-III SD cards. Samsung support are clueless as always, the documentation tells us absolutely nothing and so far I haven't found an answer to either despite hours of searching!

I know I read the sd835 supported USB-PD, but I thought the Exynos didn't. Either way, every video I've seen makes it seem like we're only getting QC 2.0.

Well... my S8+ arrived today... So I did some tests to confirm...
As suspected, QC2 over USB-A to USB-C cable (one was included with the GS8+) is how it rapid charges.
Using the GS8+'s cable with my older Anker Powercore+ 10050 (which supports QC2.0 output), the S8+ fast charges. Using Choetech and Anker USB-A to USB-C cables and a Tronsmart 5-port multi-usb charger w/QC2.0 support, the GS8+ also reports fast charging.
Using the USB-C to USB-C cable that came with my pixel, and the USB-C port on my RAVPower 20100mAh (link in an earlier post), or my Pixel's wall adapter, the GS8+ reports "charging". So Samsung is NOT supporting USB-C Power Delivery like is found on the Pixel, Nexus 6P, etc.
If you want, I can provide Amazon links to all items as a reference.

Short of timing a charge cycle using a known QC2 charger vs using a known QC3 charger, is there a way to tell? (The Ravppwer battery I have supports QC3 and I have Anker QC2 and QC3 wall chargers, and of course the Tronsmart QC2 wall charger and Anker PowrCore+ that supports QC2)
The wall plug included with the GS8+ is the same as the one with my GS7. Based on listed outputs, it's QC2. From what I understand QC3 goes down to 3.2v which isn't listed as output voltage. if the GS8/8+ supported QC3, I would have hoped they included a charger that supported it.

Quick Charge 3.0 is really more about efficiency and battery health then charging faster. Since Samsung fast charge is really just a subset of Quick Charge 2.0 anyway, it is possible for the phone to support 3.0 even with the same charger in the box.
In the end the only way we'll really know for sure is if Samsung ever confirms it or someone on this forum uses and in-line voltage meter while charging the phone to see if the voltage changes in 200 mv increments that quick charge 3.0 supports

Do we know for sure why it is that dash charging only works work the dash cable. Is it a DRM issue or a design element that needs to be licensed.
I'm not too stressed out because I plan to use a standard usb c cable for overnight charging but I am curious what is actually going on inside this charger.
I am quite familiar with OP official response concerning the matter, but given their track record of non answers, I'm assuming this situation is no different.
In other words I am curious what stops a company from releasing a cable that would in fact work. Possibly with the addition of some end user kernel changes. I understand this would be slightly impractical for a large company like Aukey or Anker to release a cable for one phone (that people could not use straight out of the box) however, my curiosity is still there
https://www.androidcentral.com/dash-charge has a good article on this.

Also, supposedly it's the same tech as http://www.oppo.com/en/technology/vooc - and anything "VOOC" branded will provide the same "dash charge" speeds.

Simple Answer to this is the proprietary high amp usb type c cable which is supplied with the stock 5v 4amp power brick work well hand in hand, it is the way Oneplus has made this..one cannot work without the other so it is packaged deal..take it or leave..unless you are willing to compromise DASH Charge you can use any other type C cable and power brick adaptor
On a standard type-c (USB 3.1) cable connected to my PC, the phone slow charges. My other devices fast charge on this cable.
The other devices slow charge when connected to Dash cable and charger.
It leads me to think some very non-standards conforming USB tech is going on in the Dash gear, enough to make Benson Leung sick to his stomach. This isn't new to OnePlus, see https://plus.google.com/+BensonLeung/posts/JmcU4rA1csh
My advice would be to never use Dash gear with other devices.

AFAIK this non-compliance thing has been there only in the first shipped cables and was fixed later on. So today's devices (this is already 2 years ago) should be compatible to USB standards and therefore other devices should load their battery at normal speed (not dash-speed) with the dash cables and dash plugs.

Should, but I don't think it is. Q: why would the OP5 not fast charge over a normal type-c connection if it were standards compliant? Answer: it doesn't comply with standards.

Amswer: OP5 doenst support any other quick charge methods (aka. QC 2.0/3.0, Adaptive Charging, Super Charging etc). It only supports normal charge or dash charge (& Vooc as dash is based on Vooc).
Also you should remember that different phones shows differently charging methods. Example Oneplus can maybe show normal 2A slow and Samsung as normal charge. Nexus 6P will show regular 3A charging as fast charging, Oneplus shows it regular charge.
For me if i use other C-cables (non-Dash charge one) it shows just "charging".
Regarding to Benson case... Original OP2 cable was non-standard. It didnt contain regular 56ohm thing. Oneplus fixed it later and dash charge cable is using standard things and also only for 3/3T/5 dash charge properties. For other phone you can use it without problems like use it to charge QC3.0 phones etc.

Amswer: OP5 doenst support any other quick charge methods (aka. QC 2.0/3.0, Adaptive Charging, Super Charging etc). It only supports normal charge or dash charge (& Vooc as dash is based on Vooc).
Also you should remember that different phones shows differently charging methods. Example Oneplus can maybe show normal 2A slow and Samsung as normal charge. Nexus 6P will show regular 3A charging as fast charging, Oneplus shows it regular charge.
For me if i use other C-cables (non-Dash charge one) it shows just "charging".
Regarding to Benson case... Original OP2 cable was non-standard. It didnt contain regular 56ohm thing. Oneplus fixed it later and dash charge cable is using standard things and also only for 3/3T/5 dash charge properties. For other phone you can use it without problems like use it to charge QC3.0 phones etc.

My point isn't so much about the cable as it is the device itself. It is a USB type-c device that doesn't conform to type-c USB standards.
There will be a plethora of usb-c ports on computers and chargers going forward. They are included on every new model of Apple, PC motherboard, and OEM PC - so type-c adoption is there and real. By ignoring these standards and producing a product with a proprietary design they are ostracizing their devices, and by extension their users, from simple and convenient charging methods. It ensures lots of sales of Dash chargers though.
It's a **** move straight from the Apple playbook. Apple made billions from the 30 pin to lightning connector change, and they will do it again with the lightning to Type-C change.
This Oppo/OP Dash charger isn't something consumers should be championing. It's not something Oppo/OP should be forcing on consumers either.

I don't think your statement is accurate, the newer USB C Power Delivery specs allows voltages up to 20 volts and amperages up to 5 amps, the dash charger specs use 5 volts on 4 amps, well within USB C PD specs. The fact that their technology is proprietary does not mean it's not standards compliant.
There is also the very important difference between voltage and amperage, voltage is pushed to devices so it's always important that what you are using within the voltage required by the device. Amperage on the other hand is pulled by the device so the charger will allow the device to pull as much amperage as it needs as long as it doesn't go over it's own capacity. Think about your standard US outlet, it works at 120 Volts and at either 15 to 20 amps, you can connect as many 120V devices to it as long as you don't exceed its amperage.
That being said, the reason other usb cables don't work on the dash charger block is because the usb A side probably has different resistors, One + cables probably have higher resistors than regular, run of the mill usb C-A cables. That was the issue with the first cables that came out a few years ago, they had pull-up resistors with the wrong Ohm rating.
Here is a link to a PDF file explaining USB C Power Specs, keep in mind though that the eventual idea is to only use USB C-C cables and not the USB C-A cables that are the cause of so much headaches.

The listed power specs are only half the picture. The negotiation between devices is critical in getting those power numbers. That a OP5 can't draw above 900mA on a fully compliant 3.1 cable from a PD capable Type-C port shows it's not compliant. Its not negotiating power draw the way a standard Type-C device should.
And yes, I've already read all the spec docs. Thanks though.

The phone itself doesn't have to comply to anything, the chargers and cables do since they are the ones providing the charge. The standards are there to determine thresholds on how much and how little current they can work with. The circuitry on the phone and battery are the ones who tell the charger how much current they need to charge the battery without warming it too much or overcharging it. Different combinations of chargers and cables will give you a lot of different charging speeds but that's because there are so many chargers and cables with different ratings that devices err on the side of caution when they can't recognize the charger that it's being plugged into them. It's kind of a unfortunate thing that companies like Motorola, Huawei, OnePlus and Qualcomm use different charging specs but all of them work within the 15 to 20 watts of power for fast charging, so it's not a really big difference.
The reason for the difference in charging speeds between the dash charger/cable and other chargers is that 1 + charger offloads the current regulation to the charger itself rather than leaving current regulation to the phone, like other fast charging devices, that's why 1 + phones fast charge at cooler temperatures than other fast charging technologies.
Now, why your phone doesn't go above 900mA on a regular cable is beyond me, the first photo I attached is of my phone connected to the dash charger via this cable and the second one is of the same cable connected to this wall outlet.

That's a fallacy. To comply with the standards does not mean, that everything is exactly the same. The USB-standard is a little bit more complex than just "pin 1 of one end has to be connected to pin 1 of the other end". The USB-standard defines what is allowed, so no devices will get damaged and to ensure a "minimum" data and power connectivity of let's say at least USB 2.0.
That's what these cables and chargers offer: They don't violate the USB standards. They allow a data connection with USB 2.0 also for non OP-devices. They also allow "normal power" (5V 500mA). They don't damage other devices. They just "work" as they should. But they offer "additional extras" (dash charging) when all three parts (charger, cable, phone) are compatible.
So they comply with the standards while offering additional features and that means, that other cables/chargers, which also comply with the standards but don't offer the extras, won't be able to dash charge.
Anyone tried to see whether using the oneplus cables on QC devices + QC wall plug supports Quick Charging?

Hi!
I have a doubt, these type of USB-C --> USB-C charger can charge the S8+ quickly than the original charger provided with the device?
http://www.sony.com.sg/electronics/portable-charger-accessories/cp-ad3
I know that S8+ is not use the USB-C charging protocols and use Samsung AFC, because this my doubt if buying this will be a improve or only a waster of money.
Thanks!
I doubt that charger will be any faster than the Samsung provided charger.
Thanks, I get one to make some test. I install the Ampere app, I don´t know if this app is a nice measure tool, but is almost the same that original charger, also a bit faster. Original in test charger session show in the Ampere app a max of 990mA, and this Sony 1020-1100mA on different sessions on both.
I'm cool with the stock charger. I'm not trying to make my phone explode and burn my house down. I'll stick with Samsung's recommendation. Just because you CAN do something doesn't mean you SHOULD.
Original Samsung charger will charge your device at 9v whereas the Sony charger will only charge at 5v, however the new USB c standard allows 3A charging so the power you get from both chargers will be very similar. I use both types of charger and find it hard to find much difference in charge times. Ampere can't be used accurately as it's only showing the charge current not voltage and you need both to calculate power and compare the 2 accurately.
I have a ton of Qualcomm quick chargers and I'm not feeling this Dash charge with its special cable restriction. I saw this adapter and from the reddit posts, it seems to work well. It even works with normal USB Type C cable. Does anyone have experience with it and the 6T?
https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=SFC+AFC+VOOC+SCP&_sacat=0
I have some coming in the mail as we speak - I will let you know once I get them tested. There are supposedly some signaling differences between different OP versions, which may require a new adapter.
My take is that none of the WEB- adapters (on eBay) would work with the 6T, since that manufacturer is already selling a specialized adapter for OP beyond or equals to 5T. The WEB- adapters, however, offer a wider range of fast charge protocols as opposed to the YZXStudio adapter, which supports only VOOC-DASH. The YZXStudio adapter also has a current cap, which you can slightly adjust by soldering pins on the adapter itself. You are unlikely to get the full benefit of DASH from the YZXStudio adapter because of this cap, although your Quick Charge chargers most likely will be the limiting factor. Also note that the WEB- adapters require an input of at least 10 or so volts, so their A2A adapters will automatically request QC2/3 @ 12V. If your adapter does not support 12V, then it would not work properly. Your adapter should at least output 12V @ 1.5A for it to be any good after conversion losses.
This cable works although it seems to have gone out of stock.

I think the OP is trying to avoid using OP specific cables but rather use a QC2/3-DASH adapter and a normal USB-C cable for charging the phone. That said, aftermarket cables are not that expensive on AliExpress, eBay, or even Amazon. Although if you insist, I would encourage that you get heavier gauge USB cables for this...

Thank you for the information. Please let me know what you can find. I do have QC adapters that support 12V. If there're adapters that works, I rather buy those instead of investing in new bricks, cables, car chargers, battery packs,... My other devices either support QC or PD. Investing in Dash charger doesn't make any sense at all.

I hear you - I did buy a multifunction car charger that supports both QC3.0 and DASH - I will report whether that works when it comes (hopefully later in the week if not the following week). I have also gotten the specialized versions from WEB- in China so once I get those I will let you know.
So I got one of the adapters today - this is an older version that does DC to Type C, so I did not expect it to work (even though it specifically listed VOOC and DASH support - maybe it worked for an older OP version).
This one was from eBay, and supposedly the seller sent me the wrong item (WEB- makes a 12V and a 20V PD version - and instead of the 20V version they sent me the 12V version instead - which can only decrease voltage due to the builtin buck converter inside).
So the question is - does it work with DASH charging? --- No, it did not. However, it is still an interesting adapter because it has broad fast charge technology support. They market this little adapter to convert your "dumb" laptop charger into a "multifunctional charger."
Interesting facts:
1. This adapter requires 12V for it to function. It does start turning on at around 11V or so, and anything below that will cause the output to shut off and the operation light to go red. The USB to USB version automatically requests QC @ 12V, but obviously, this cannot be done on a DC jack (on this particular version).
2. As soon as the voltage going in exceeds 11.5V, the output turns on with a steady blue status indication.
3. The USB-C version of this adapter supports USB-C Power Delivery (PD2.0) with three selectable voltages 5.00V @ 3.03A, 9.00V @ 2.39A, 12.00V @ 2.31A (there is a 20V version that supposedly does 15 and 20V as well for laptops, but the seller sent me the wrong version).
4. The input side is a 5.5 x 2.5 DC jack, which is somewhat odd as an input because most input jacks use the smaller 5.5 x 2.1 jack (you can use an adapter on it, however).
5. You can see from the tester that this adapter supports pretty much everything, except VOOC/DASH and 20V QC and AFC 12V.
6. QC 2.0 9V engages just fine to charge my older Nexus 6 via a USB-C to USB-A adapter (since the D+/D- lines are intact).
I do have more adapters coming in soon so I will let you know how they go once they come in (including the WEB- VOOC/DASH specialized USB-USB adapter). This particular version may be a fun adapter to play with, although it won't really help with DASH charging on the OnePlus.

Here's an update on the car adapter I have received. Note that the other adapters are still on the slow boat so I will get to them when they arrive. This isn't necessarily what you are after, but nonetheless, it's another interesting toy. If you are interested, it can be found on AliExpress under item number 32916499372.
This is a car charger that accepts 12-24V input, and also supposedly supports multiple fast charging technologies (DASH, VOOC, QC, etc). It comes with an "original" (questionable - but capable of 3.5A charge) DASH cable which is not bad at all for about $13.
Interesting facts:
1) The car charger comes with dual USB ports. One "quick charge" port and one "standard" port. The quick charge port lights up red on one side and the blue indicates the normal charge port. Some may like that it lights up, but my thought is that it's a waste of energy.
2) The Quick Charge port supports all available quick charge methods (the VOOC-DASH section don't light up probably because it doesn't use the same protocol for unblocking DASH charging that the original charger requires).
3) The charger does not require an ID chip on the USB-C cable (unlike the stock charger), which means you can use any USB-A to USB-C cable on the market to activate DASH charging (as long as the D+/D- pins are not shorted out). This car charger doesn't even have the odd PIN in the back of the USB connector for the ID communication.
4) The car charger is not as fast as the stock wall charger, which charges around 3.5A. Here are the test comparisons (allow some current variances due to battery percentage ~70-72% - note all of them had the lightning bolt on the charging indicator which indicated that DASH was indeed activated with none of these cables having D+/D- shorted):
a) Normal, 1 ft USB-A to C Cable: 2.46A
b) Bundled DASH cable, w/ car charger: 2.73A
c) Bundled DASH cable, w/ stock wall charger: 3.5A
d) Normal, 3 ft (Rankie) USB C Cable: 2.56A
e) Normal, 3 ft MicroUSB w/ USB-C Adapter (ANKER): 1.95A
f) Normal, 3 ft multi (MicroUSB + Type C) free conference charging cable: 1.32A (this one did not "pass" the fast charging test because the current is below 1.5A but nonetheless it triggered DASH charging).
Not a big difference if you use quality cables, although don't expect it to charge as fast as the wall charger - nonetheless, it is still doing pretty well with less heat generated due to lesser current.
5) As mentioned previously, the charger supports multiple charging technologies besides DASH, where it activated QC 2.0 9V on my Nexus 6 just fine.
6) Since this adapter allows 12-24V DC input, you can use a DC to lighter adapter to power this device (as you can see in my screenshots I used a laptop battery pack and a 12V router wall brick and it was able to turn on and charge my devices just fine.) This may also be a good way to have a longer reach charging solution since DASH is very cable sensitive and it is best to keep the cable length short to minimize the reduction in charging currents.
Here's a test of the 100 cm noodle cable on AliExpress (item 32806193071):
Using the stock wall charger, charging the phone @ ~50%:
The genuine OnePlus cable was able to charge at 3.657A @ 4.69V (17.15W).
The noodle cable on AliExpress was able to charge at 3.617A @ 4.81V (17.4W).
Based on the results, it seemed like the quality was as good as the genuine cable, at least the copper that is carrying the power to the phone.
Here are the test results of the final adapter I received from WEB- (the specialized VOOC-DASH version - Taobao Item #560336325713):
Stuff to note:
1) This adapter is very similar to the car adapter, in which it supports pretty much all quick charge technologies and it does not require the OnePlus ID chip to activate DASH charging. However, this adapter is QC activated and has a USB-A input interface. Like the car charger, this charger is also not as fast as the stock wall brick, although it is still relatively quick.)
2) The USB pinout schematic also looks the same as the car charger (USB 2.0 with no dangling USB 3.0 pin in the back for ID chip identification).
3) Like the other 12V based WEB- adapters, this one uses the IP6518C chipset, which supports a wide voltage input (10.5V - 32V - from the chipset datasheet).
4) The board looks fairly similar to the USB-C board, except this one has a USB-A input (which is interesting because the board has the DC 12V-24V marking on it still).
5) The board also has the POW and OK lights similar to the USB-C version.
6) Since the board accepts broad input voltages, it is not required to use QC for the input voltage. A USB-A to 5.5 x 2.1 adapter could be used to also provide the DC input, as long as the voltage is above 10.5V.
7) Although the board indeed supports down stepping a 20V DC input, it seems like it is a bit less efficient in doing so than a 12V input.
8) Similar to the previous cable tests, the quality and the length of the cable really makes a difference. The shorter and the better quality cable that is used, the better the charging rate (remember that an official cable does not need to be used for third-party chargers).
9) As mentioned previously, this charger supports other fast charging technologies, like QC2.0 - which works fine in charging my Nexus 6 at 9V.
10) This charger / adapter essentially allows any 12V @ 1.5A output to be a multifunction fast charger w/ DASH support. In my example, I used a Xiaomi router wall brick (12 V @ 1.5A DC) and it charges my phone using DASH at almost 3A output using a short 1ft USB-C cable! (the phone registers the current slightly lower at around 2750mA).
Great info, @chowfun. I was able to purchase 2 OPPO wall chargers from Asia and a 3rd party VOOC car charger which work great.

I also got the same oneplus flat cable but 150cm length. It works good with no notable slow down.
From your findings, it looks like the WEB- adapter charge slower but that's still plenty fast and much more convenience. :good: Does it generate a lot of heat when charging a low battery?
Nice keyboard, I like it. ?
That said, the Quick9 charger you bought probably does not require the ID chip as far as DASH is concerned. I didn't get that one because it had a lower current rating and that the top of the charger is wider than the other one I bought. I doubt the OPPO charger would work with a regular microUSB cable since I presume that it also requires the chip on the cable end... Did you also see what kind of maximum currents you are seeing on those chargers?
Heat wise, it does generate a bit of heat with the conversion. But given that the adapter is housed in an aluminum case it's to be expected. It feels just slightly warm to the touch, but not exactly hot to the touch. Instead of that conversion being done in the phone it's just being done outside the phone which is directing the heat away from the battery...

The input and output of the OPPO charger look exactly the same as the 1+ charger. It's pretty much identical except for the cosmetic (logo, prints, the USB A female is green). They're selling for $4.
