Question Charging speed with USB-PD chargers? - OnePlus Nord N200 5G

What charging speeds can you get with QC, USB-PD or USB-PD PPS chargers? Higher than 7.5W / 5v 1.5A at least?
I see OnePlus lists it's charging speed as "18W Fast Charging (9V/2A)". And 9v doesn't match the 5v or 10v that I've read Dash/Warp/VOOC has used. So I'm hoping that means it supports more that just Dash/Warp.
If the nord n200 does require only Dash/Warp, anyone know which version?

According to this link:
https://www.reddit.com/r/oneplus/comments/u78u1o
The "PD" indicator on a cable with integrated power meter lights up, so the author thinks it is USB-PD.

Getting 10.2W (8.88v 1.15A) with QC. Battery was at 75% though. Have to test further at a lower charge level.
Used a Motorola "turbopower" USB-A charger, model: SC-22, which apparently does Qualcomm QC. Labeled as capable of 15W, 5v 3A, 9v 1.6A or 12v 1.2A.
~edit~
16.3W (8.94v 1.83A) via Qualcomm QC with a different cable and the battery at 10%. Max rate my charger is capable of.

Aftermarket Charger

Are there any aftermarket chargers that will work like the oem Motorola Turbopower chargers?
Pretty much any USB-C charger will work. I've used an old USB power brick with a USB-B -> USB-C cable, I've used my Acer R13's USB-C 45W power brick, and I've used my Choetech 55W 6-port charging station with a USB-C -> USB-C cable. They all work.
If you're looking for something that works with the X4's Turbopower, that's basically just Qualcomm Quick Charge 2.0 under a different name. My charging station is QC 3.0, which works with QC 2.0 devices, which works with this Moto X4. It charges quite fast.

Think our X4 needs QC3.0 for turbo charging. I have several QC2.0 chargers left over from my last phone and they do not charge this device at full speed. Also I'm pretty sure the original Motorola charger that came with it is QC3.0 according to what I've seen. But I've just ordered my first after-market charger (a RAVPower car charger, model VC007003) and can report back when it arrives later this week.
Looks like QC3.0 is the ticket
Here are screenshots of the charging rates using both my old QC2.0 and new QC3.0 chargers. The new one activates the "TurboPower connected" toast message, which the old one did not, and charges at a much faster rate. Gonna check out some QC3.0 wall chargers in the near future now.
Yes.
Anything from Qualcomm's certified list.
The original charger is 5V, 3A (15 Watt). However, most Qualcomm QC 2.0 chargers from 1 or 2 years ago ran at 12V, not 5V for fast charging so they don't support the combination of 5V 3A. It's the same thing that happened with the Nexus 5X which technically didn't have Qualcomm QC either, despite having a Qualcomm CPU. Forget the branding on the charger since it is too unreliable, and just find yourself something that can support 5V, 3A.
Wireless charging station for Moto x4?
Anyone know of a wireless charging station that works on the Moto X4? Got my x4 from Project Fi back in October and now it won't charge with a standard usb c cable. The phone and usb plug gets hot.
I'm using Pleson Fast Charge stand and CHGeek Wireless Charging Patch. The charging patch is kind of unsightly but I don't care, it charges "Turbo" fast.
Uhmmm

That may explain why my Nexus 5x charger can't charge this Moto x 4 (it takes forever to complete a charge) but technically it still works
I've gotten turbo speeds from several different Quickcharge3 chargers from Anker. As a side benefit, they also do a good job charging my wife's iPhone.
For me this cable and this wall adapter do the trick just fine.

Fast charging USB C PD power banks?

I bought this power bank: https://www.amazon.com/gp/product/B01LRQDAEI/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1
Unfortunately, it doesn't fast charge my Mate 10 Pro. I have a USB C PD car charger and wall charger, both of which work fine and fast charge properly. (Tried multiple cables too). I'm wondering if there's some negotiation issue because this power bank has a bidirectional USB C port (i.e. you also charge the power bank via USB C).
I'm gonna try this one next: https://www.amazon.com/gp/product/B075NXR2T4/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Anyone know of a USB C PD power bank that works?

Hmm those would indeed probably work. I'm really looking for something that supports USB PD so it will work with all my other devices though...
The Mate 10 pro is not USB PD compliant.
You can kind of "quick charge" it by using a non standard charging protocol, like 9V 1,5A, but truly "supercharger" at 5V 5A, only with a Huawei supercharger device / cable.
So probably the other chargers you have support other proprietary 10 and 15w solutions that your power bank doesn't.

So I ended up buying a USB C power meter. Despite the phone not supporting USB PD, as you claim, it negotiates 16W (9Vx1.8A) from all four charging devices I've tried. But for some reason the power banks don't activate fast charging, while the chargers do... I'm not sure where all the current is going, if not the battery.
FWIW, ugreen seems to think USB PD is supported: https://www.ugreen.com/news/186-en.html

I never said that the Mate wouldn't charge a faster rates, I said it isn't PD compliant, if it was USB-PD compliant, you'd get 22W.
Most chargers / power bank have compatibility for the until now used "broken" quick charging protocols, just because most devices don't support PD as of right now.
I wished the Mate would have support for PD, this would also mean fast charging and data stream at the same time (by using a dock), but try and plugging a dock that's USB-PD compliant (like the many found for the MacBooks) and plug a USB device or a HDMI cable and charging speeds drops significantly.

What makes you think it doesn't support PD? It's obviously negotiating power somehow, and the cable I used doesn't have the D+/D- pins, so it would have to be using some other protocol over USB C...
Also none of this really explains why it's drawing 1.8A off 9V from the power banks, but not fast charging.

To make terminology clear, we are talking about USB-PD rev. 2, the one found in th Pixel, MacBook, and others right? Not rev 1 or the USB battery charging protocol, those are basically outdated.
Because I see you're using a modified cable and PD rev2 needs a USB-C to C compliant cable, the specifications calls for 4 power & ground pairs and a separated communication bus.
That's why USB-PD rev2 cannot be served via USB-A plug.
Well, why do I say the Mate 10 is not PD compliant, well, take a PD compliant charger, cable and dock, connect it all to the Mate 10 and watch it either charge a 0,5mAh rate or the phone go crazy it will recognize a charger, then say it's disconnected, then say it's connected again, and so on in a continuous loop.
A USB-PD compliant device is able to handle fast charging, data and video output all at one.
I've tested this with various combination of docks, cables and chargers, and none worked... Intimation online is though to find, Huawei's official statement is "our phone supports the best, fastest, safest....." Bla bla bla....
Since most PD rev2 chargers are backwards compatible, you can use them to charge your phone just not at the "optimum rate"... 9v 2A (ish) is the last generation (Huawei P9) Huawei fast charge, and it's mostly the same profile as the Samsung fast charging, QC 2.0 and some other variants, the Mate 10 supports it too at this theoretical of 18W (although I suppose that the speed will be much slower).
The optimum "supercharger speed" is 4.5V 5A, and it's not a standard at all, that's why only Huawei chargers will be able to provide it, I also suppose that there is a lock preventing users from use the dash charger power brick for example.
But back on track, when you said that your phone is not Fast charging, I supposed that you meant that the phone was charging at a really low rate, but is it? I mean what's the difference that you are seeing between your power bank and the other chargers?
Have you tried using a USB-C to C cable from your power bank?

Correct. I'm talking about USB PD 2.0. That's interesting, because I don't see the same behavior you're talking about. I wonder if you have a different model? Mine is BLA-A09
All of my charging devices are proper USB C, and support PD 2.0, and I used a marked 100W certified USB C cable. I later used a cable without D+/D- pins to test if its negotiating power using something other than USB PD. Behavior was the same.
This is what I sent to Huawei, and they basically told me the phone is optimized for their own charger. The problem is that despite negotiating, and drawing the same power from all chargers, with the power banks, it does not go into fast charge mode, which you can see from the different charging icon and the longer time to charge.

Ah clear, the iconography is a bit different on my device, must be just a firmware difference.
Your phone is drawing the same amount of power mostly, the charging rate should be very similar.
What about something like ampere or accu battery to check the estimated charging rate?
There are specialized devices for checking the negotiation between both devices, I suppose that it's just a question of a different chipset not triggering the fast charging status in de kernel.
Ps: my phone charges normally, I just that when connected to a dock, sadly it can't charge at more than 2,5W (at most 4w), because it isn't compatible with the newest standard that allows for double role data and power.

Good suggestion. I used accu battery and compared charging between battery and wall charger for 5min at around the same battery %. They're charging at exactly the same rate. So it's just some kind of UI bug that's showing the wrong icon and charge time... Now how do I get them to fix it?
That is a bummer that dual power+data is not supported!
There was a Chinese website which published some USB PD charging tests with the Huawei Mate 10. 28 different chargers were tested. I can't recall the URL offhand.
IIRC, general conclusion from their tests was that the Mate 10 could draw 9V 2A from most USB PD chargers. And that the Mate 10 only accepts 9V input voltage for USB PD fast charging.

Does plus really support Quick charging?

Hi i read that redmi 5 plus support qc so i had aquired samsung quick charger.When plugged phone shows quick charging but when i mesure mA while charing with qc and with normal charger there is no big difference according mesuring software.So what is real truth about qc?

Redmi 5 Plus supports QC (3.0 to be exact, as it's Snapdragon 625). Apps measuring charge rate won't show you real current, it's only approximation.
I've tested my charger, which supports QC 3.0, my 5+ uses 9Volts at almost 2Amps (when charging from 15-20%). Measuring software won't show you voltage that you are using to charge so you may not see the difference. But doing quick math - 5V*2A=10W (standard charging brick) whereas QC charger will use 9V*2A=18W. That means you are charging with 80% more power.
Keep in mind that charging with QC will get your phone a bit warmer, so phone will start to throttle the current, meaning that you won't be charging from 0% to 100% at full 18W
Yes. It charges with 9v and 1,7 amp max. (9v is static, amp is variable, that means it has only QC 2.0 mode.)
Its way faster than standart charger. I have Tronsmart QC 3.0 charger. But you can go with QC 2.0 charger.

Power Supplies for Tab S4

On another thread, Berkowich made mention that Tab S4 supports PD Power, but not CH3.
These were not terms I was familiar with, so I turned to Google... So QC, QC 2.0 and QC 3.0 make sense. The "adaptive fast charger" in the box with the Tab S4 has outputs at 5 & 9 volts, so I assume it is QC 2.0 and it switches between 5V and 9V as the battery is filled to more efficiently charge the battery. But I see QC2 talks about 5V, 9V and 12V. So is this the same and/or safe? And it isn't clear to me how PD Chargers are different? Just more current? Are they safe for the Tab S4? What is the type of non-Samsung charger to buy?
Thanks
Joe
PD typically refers to USB Power Delivery, which is a fast charging specification developed by the non-profit USB-IF organization. It is the actual open-industry standard.
Quick Charge, even though it is in many devices, is actually a proprietary standard owned by Qualcomm. Some device manufacturers choose to not implement QC even when they use Qualcomm chips in order to save on licensing fees.
QC 2.0 & 3.0 are not in compliance with the USB-PD specifications. However, QC 4.0 is.
Samsung has its own quick charging technology and only some but not all of their devices are compatible with QC 2.0 standard.
USB-PD - https://www.usb.org/usb-charger-pd
Official Certified QC device list - https://www.qualcomm.com/documents/quick-charge-device-list (Note that the Tab S4 is nowhere on the list)
Let me reask the question....
I have have several different types of chargers... Older 1A and less chargers from miscellaneous devices. A few 2.4A / 5V chargers that either came or were purchased for older devices I have around the house. Two Samsung Adaptive Fast chargers (9V/1.67A + 5V/2A), one that came with the Tab S4 and another that came with an S7 Edge.
So which of these is optimum for charging the Tab S4?
Will the 2.4A charger be slower than the 2A adaptive charger?
Is there another type of charger that would work better for the S4?
Can some chargers damage the S4?
Does it make a difference if I'm using an HDMI/USB hub? (Mine always says I'm slow charging / draining the battery when I plug the 2A adaptive charger into the hub.)
Thanks for your help -- this is a more complicated subject than I thought.
Edit: there's a link on the charge time thread that leads to another link that helps answer some of my questions.
https://www.xda-developers.com/charging-comparison-oneplus-huawei/
https://www.digitaltrends.com/mobile/how-does-fast-charging-work/
This seems to say that the best bet is a Samsung adaptive charger or a QC 2.0 charger that will throttle back to Samsung's standard.
This doesn't answer what is best when using a hub, and what dangers there might be using non Samsung chargers.
On a related subject, years ago I learned that all USB 2.0 charging cables were not equal -- that you need to look at the gauge of the charging wires, and that you could have huge differences in charge speed based on the cable you used. Are all USB C cables equal with respect to charging? Or do you need to look for fatter gauage / bigger wires to get more current / less voltage drop over the cable?
thanks,
Joe

Actually does someone that has an accurate usb meter help us. When i look for the charging support for the Snapdragon 835 on the web, it says QC4.0 but i can't find any QC4.0 chargers and i think it is the same with PD that i say on the other thread (it is just a think by the way because there is no QC4.0 chargers soo it is maybe a PD equivalent).
By the way when you are using the HDMI dongle(just HDMI and charging) did you use the original charger and the cable because there is no slow charging notification when i use it?

Quick Charge, Power Delivery and USB charging for Realme 7 Pro

Hi, I would like to ask about SuperDart 65W (10V, 6.5A) from Realme 7 Pro. It charges every of its two batteries at 5V and 6.5A (32.5W each) but I found information that it suppots Power Delivery and Quick Charge 18W as well. With PD and QC you can charge the battery at 9V , 12V, 15V etc. but not 10V. Does anyone know at what voltage the smartphone will be charged if you use PD or QC charger?
Is it safe to charge it with higher/less voltage? (e.g. 2x4.5V or 2x6V if 5V is needed for one battery)
And what about the standard 5V chargers and usb 3.1 (e.g laptop)? Is it possible to charge 7 Pro with it?
Generally, all fast charges will drop ther voltage when the connected phone doesn't support it.
With lower voltage you wont have any problems other than the speed of charging, which will obviously decrease
Standard 5V chargers will work just fine
Normal laptop usb will work just fine, in fact you will be lucky if the laptop supports any sort of fast charging at all
You are 100% safe to charge with pretty much any charger to my understandment
