Preview, Choetech quick charge 3.0 accessories

Hi All,
Got a car charger and multi port charger coming from choetech, I've used their stuff in the past and they are up there with anker as 3rd part cable companies go.
heres an early preview of them, They are looking for beta testers so you can sign up here: http://www.choetech.com/Support-review.html
Be interesting to see what these are like with the htc 10, i will let everyone know more once i receive the items.

@Phil750123, Thanks for sharing this information, I'll be glad to test the car charger!

I actually have the qc3 wall charger. So far it's charging pretty fast on my s7. Agree with other posters that the quality seems really good. Will know how it compares to stock when I get the HTC 10.

Yeah their quality is great. They were the first to come out with a good USB type C wall charger for the Nexus 6p

They're just a little bit logo happy.
RoHS eh idk. Fake CE.. And don't even get me started on that FCC logo.. Someone needs to tell them who/what FCC is..
The Federal Communications Commission (FCC) regulates interstate and international communications by radio, television, wire, satellite and cable.

Why on earth would a charger need that..
To me they just look like another chinese manufacturer.
Atleast have the brains to use appropriate logos so they'd be semi passable, like I don't know TÜV or UL and so forth..
And, of course, they're nowhere to be seen on Qualcomm's certified accessories list. Not even any QC2.0..
P.S. I did apply for testing, they sent me an email, I replied. Let's see if they send something lol. I'm not a liar so I'm gonna be honest if I do get their stuff for review

Yer they look decent I already have some of their usb c cables, I've just ordered the qc 3 portable charger from them aswell so il review them all and see how get on. But yer they make no mention of favourable reviews they just want a review, which means they are confident in their products which hopefully means they are good

Nice, I have some on the way, they look good.

I actually asked this question at qualcomm but they wouldn't answer, maybe someone knows the answer here, hopefully it is not too confusing.
I was wondering about the QC 3.0 technology chargers. My question is, say I buy a wall charger or a car charger that supports QC 3.0); will it charge my type C phone (say an LG G5 or an HTC 10) as fast with the QC 3.0 technology using a type A to type C cable? I know if I charge a type C device using only type c it will get me faster charges, but if I do type A to type C (with QC 3.0) with the right charger will I still get the best results?
Thanks.

type A to type c wil reduce charging times even with 3.0. I went with these cables and for a car charger I got this one both should give the rapid charging.

Thanks for clarifying, I wasn't sure. I think the HTC 10 charger comes with 3.0 quick charge, but it is a type A to type C.

I actually just got my QC 3.0 Powerbank from Choetech and I love it. Charges everything fast just like the spec allows for, and has a great build quality. One small thing I like is that when fast charging, the first light to the left switches from blue to green to indicate that. I just appreciate the assurance that my device is gonna be juiced up quick. The only thing that's odd about it is that you need to press the power button for charging to begin. I'd prefer it to just start when a device is connected, but that's my personal preference.
Overall I still really like the thing, great to have a powerbank that charges just as fast as my wall charger, before I was stuck with one that didn't have and QC capability. I'll include some pics below.
If anyone has any questions about it, let me know. Should also be getting a 6 port QC 3 charger from them soon too, will post on here when I do.

I was looking at this on Amazon last night, but they don't seem to be on Qualcomm's official partner list, which makes me a bit nervous for my battery (which I'm not super impressed with anyway so far - one of the reasons I was looking at the power bank). Do either the phone or the charger get hot while charging? The HTC QC3 charger seems to prevent overheating.

They aren't, but speeds have been up to par with what I'd expect from QC3 so far so I haven't had problems with it. The charger gets warm after a bit, as does the phone (warmer than with stock charger) but also nowhere near as much as the M9 would when charging. Don't know if you've used that before, but when charging regularly it would get so hot that it had to stop, and that's even with screen off. It was crazy bad at charging, which is a thing I never thought I'd say about a 2015 flagship....so I'm glad the 10 is better in that regard, at least. I'd imagine almost any third party charger is gonna make the phone hotter than the OEM one will, but I didn't have a problem with the heat it generated, overall.

Im still waiting for the main qc 3.0 to arrive from china, but i also got the choetech qc3 portable charger and it works great.
Im just waiting for my usb multireader to come and il check out the voltages etc.. just to double check its all safe, but i've had choetech stuff in the past and had
no issues, they have good warranty so they must trust their quality.

Charging Speeds and Confusion

Hey guys! I've been a long time lurker and finally have decided to come out of the woods and get some help.
I'm looking to order all my accessories today however I want to make sure I'm getting what I need so I don't have to go back and buy different cords.
I guess my first question is: Will a USB C to USB C cable charge faster than a USB A to USB C cable? Or does it all depend on the wall/car adapter?
I was hoping to buy 3 USB C to USB C cable with an extra wall adapter and car adapter. The whole USB C and QC 3.0 discussion has confused me like many others. What do I need? This is what I was looking at getting:
Anker PowerLine USB-C to USB-C 2.0 Cable (3ft): (Can't post links...)
USB C Charger,Tronsmart 30W Dual USB Wall Charger with Quick Charge 3.0 Technology: (Can't post links...)
USB C Quick Charge 3.0 AUKEY Car Charger with Dual AiPower Ports: (Can't post links...)
Do all of these products seem that they would give me the best possible charging times and be safe to use with the HTC 10? I appreciate all the help!
Thanks much!

I'm using the Aukey in my car and it charges really quickly and the popup for rapid charging comes up.
Can't really recommend the others only the one I have.

So you use USB A to USB C? There won't be a noticeable difference between the charge times if using a USB C to USB C cable?

type a to c "may" limit speeds in some situations. like this car charger you wont get the quick charge from they type A to C but if you use the type c to c in the other port youll get the speeds with say these cables here

The phone can't support two USB specs simultaneously because that's a direct violation of the spec. If you use a C-C cable with a charger that outputs via QC 2.0/3.0 then it will charge at QC 2.0/3.0 speeds. On the other hand if you use a charger that is for the Nexus 5X/6P which outputs using the USB-C charging spec (5V/3A: 15W) then it will charge slowly at 1.5 A not fast charge. This is because it can only support one standard or the other no both, so I recommend just getting QC 2.0 or 3.0 chargers and use whatever port they offer. It could either use a conventional USB-A or the USB-C as long as you use the appropriate cable and the charger spec matches your phone (Qualcomm quick charge), then there won't be any issues.

Ahhh that makes sense. Perfect response! So I'll plan on getting QC 3.0 chargers and just match the appropriate cables. It will probably come out to be cheaper this way as well.

Not a problem, I actually wrote up an OP showing the expected charging speeds via different charging methods across the devices that I own. QC 3.0 isn't faster than QC 2.0, but to conclusively prove that I will add a QC 2.0 test conducted with my HTC 10 to my OP linked below. Since I own a Nexus 6P, and S7 Edge so it's easier for me to test and check that which is why I mentioned it in my comment.
Here is the OP: http://forum.xda-developers.com/htc-10/how-to/comparison-htc-10-qc-3-0-charging-test-t3377397

Very cool. I'll check it out.
Any idea why I can't find a solid wall charger for under $25? Anker's is $26. iClever has one for $13 however I've never seen iClever talked about on here.

I just finished testing the charging speed using a QC 2.0 charger and the results were very interesting. I'll post them up tomorrow, but I don't see what the big deal about QC 3.0 is.

Efficiency. Nothing more, nothing less.
I can't understand where people have gotten the impression that QC 3.0 would somehow be faster than QC 2.0, with phones that is.

Qualcomm claimed that it was faster.
Even being more efficient, it should be at least a little faster and produce less heat... both of which are good things.

I posted a picture from Qualcomm where they state QC 3.0 is faster. In reality QC 3.0 is not faster, or even better from what I've seen so fsr. I didn't notice a difference in the amount of heat generated, technically the higher the volatge and lower the rate will result in a cooler phone but QC3.0 does the opposite.
Here is the slide from Qualcomm again where they say it's faster.

It's just 10% faster. You will be hard pressed to see these 10% in real life scenarios.
When they are saying it is less heat dissipation they are talking about the charger. The efficiency of power transfer is in the charger.

It doesn't even charge 1% faster, in fact it's slower. There wasn't a noticeable difference in heat when I tested it. I didn't actually measure the temperature because I don't think an app will accurate depict the temps, but I can to see if it is cooler. QC 3.0 isn't all its hyped up to be unless something changes I don't think it's really all that great.

I tested out of curiosity the charger from the Note4 (QC2.0) and it is fast as well .. but I could not see any noticeable difference. ... Then again, my phone is just 4 days old so the battery is not up to speed (it requires about 5-6 cycles for a Li-Ion to get to the full potential). Maybe you are right, maybe I'm right .. I do not know yet.
However, if I reach a definitive conclusion with my gear I'll post it here.

I've verified that more or less with my testing so for better or worse we have QC 3.0 if you choose to use it.

My biggest concern... USB-C

I've got a lot of devices that use micro usb, and several quick charge adapters and hubs.
From my understanding the OP3 will only quick charge when using the specific charger and cable that comes with it.
Now I'm wondering if I'll no longer be able to charge while driving and using GPS... only true quick charge seems to catch up to that kind of drain.
Anyone have an idea how this might work?

I too heard that only its own charger will charge it, but with root and custom kernels I can only imagine it'll get open to any usb-c cable

It would still charge with any cable but not at "Dash" rate!

OnePlus AMA on Reddit they say there are Power Management chips built into the Chargers so doubtful of it being opened up to any USB-C cable at Dash Charge rates.

Nope not true at all. Any charger with a USB-C cable will charge this phone. Confirmed by Andrew on Android central

I submitted a question on what kind of usb type C connector they used. I'm wondering if they circumvented the "official" type C connection in order to implement their dash charging tech.

Get the £25 Car Charger that will stop problems with drain.

Okay, reading through the thread, I feel like I can give you some definitive answers, and maybe solutions as well.
1) The Dash charging management IS offloaded to the charger. This means that only a charger with the built in functionality will trigger Dash charging safely. However, they WILL be selling accessories for cars, walls, etc. Might be available now. Keep checking, and if you're really curious you can call them and find out if they have any plans for the above.
2) ANY USB-C cable will charge the device, but not at QuickCharge/Dash speeds. This isn't a matter of triggering it in the device via software; the device is missing the hardware to make this work without the proper chargers. So it WILL charge, but at normal speeds.
(That being said, I ADVISE AGAINST using any charger that's not branded for the device. These things can and have caught fire and gone boom, and there's a reason they test the **** out of them before releasing them into the wild. The kid in China making $2/hr does not get paid enough to care if you die, so that's your responsibility.)
3) The inclusion of quickcharging means you can get to a destination with a plug and be reasonably charged within an hour. Unless you're a trucker, you'll probably just need to carry a charger around with you if it becomes THAT much of an issue, or keep one at your destination (I do this with my HTC 10, since i only have one plug. Works fine, lasts overnight and the 1 hr train ride to work.)
Hope this helps.

I have a nexus 5x that has usb-c with no issues. I use the stock power brick to charge and bought a respectable anker usb to usb-c cable for my pc. Can use that to adapt to my car charger to. You shouldnt have any issues. When my op3 gets here ill still use the same anker cable.

I've been using the Anker 4.8A / 24W car charger for at least a year and have (quick charged) my Note 4, LG G4, Moto G, and other devices without any problems. But I've never owned a USB-c device, so I'm weary about using it.
I honestly don't want to spend another $100 on an extra adapter, cable, and car charger just to make it a little more convenient!

Well, while it is type C, and can charge at 2.1amps, it is also wise to understand the factory charger and cable are capable of so much more. It is essentially OPPO's VOOC, which takes the heat out of the device into the charger and pushes about 20 watts, even while the phone is active.
The below video (i came across) has a great comparison.
https://www.youtube.com/watch?v=gAS76EZ87dc

I don't wanna start new theme. So quick question. Does this usb-c support any hub with hdmi, full usb 3.0 (or2.0)and usb-c charging?

Keep in mind USB-C is the new standard, everything next year will be USB-C. So whats the difference between spending $100 on new chargers now or $100 next year when it is the only choice you have?
Also a quick google-foo shows there are several USB-C to HDMI/USB/USB-C adapters

Thanks for that info. I have to look that article up. I just wonder will is have USB-C Power Delivery 2.0 to Rapid Charge. I now know that not every smartphone that has a USB-C port rapid charges. Neither my Nextbit Robin nor HTC 10 do, and I later found out they weren't USB-C Power Delivery 2.0 compliant.

Not sure why you refer to USB-C to HDMI or DP but OP3 does not have video out support.
Think I'll just take the hit on my wallet and buy a spare Oneplus dash charger. I'm slightly annoyed they went for a protected system, when Apple did it we were unhappy, so far I've not seen the community complain about this new Oneplus 'feature'.

I was going to complain, but then I did the research on DASH/VOOC and realized it is best in class, better than anything on the market to date. Quickly Charge with little heat... I'll pay 30 for a 2nd charger. And if I am in a bind, I'll just use normal USB C and suffer as I do now with my 1+1.
My only grr moment is seeing a car charger is $30.

sorry did not see this. the oneplus 3 charges at a much slower speed using the stock nexus 6p charger. i checked

I use the dash charger at home and a standard 2.1A Capdase Power adapter in the car and a 2.1A Capdase Wall Adapter at work. Obviously only the Oneplus Dash Charger Charges at lightning speeds. But to be honest.the other chargers also do faster than normal charging. Im comparing from my oneplus 2 that one used to take forever to charge. I get a full charge with the dash charger in say abt 45 to 50 mins. And with the normal charger in about 1hr 30 mins. Which is still quite fast IMO. Oneplus 2 used to charge completely in about 3 hours. Im using the oneplus 3 cable with the Dash charger. The Oneplus 2 Cable in my car and an UltraProlink USB to Type C cable at work.
Tldr. Dash charger works super fast. Other normal chargers work just fine.

That's great, It takes me about 70-72 minutes for a full charge from 0-100%. On top of the speed, I really appreciate that it doesn't overheat. I feel more confident with any smartphone that doesn't overheat while charging.

all my usb-c pd chargers report slower charge speeds than the stock 25w brick.

Guess we will hear more about this later with ppl with the proper equipment to test this, but i'm just gonna base this off the phone notification.
I'm getting the same estimated charge time using my 30w macbook charger, 60w monoprice usbpd charger, 18w usb-pd anker power bank, as a standard adaptive fast charger I have in the house (15w i think?).
Meanwhile the 25w brick that comes with the phone cuts the time by about 10min or so vs the other options above.
I did read about the 45w situation to be tricky, but this is the first time i've heard about the 25w charger being special in this way.
Would love to see more tests and see if there are 3rd party solutions that can get the full 25w speeds, and maybe the 45w ones.
hopefully its not a oneplus situation where you can only get the best stuff from their own first party chargers.

Was reading u need a Type C E cable, whatever that is. I bought a 45W wall charger and still waiting on phone to see what's the deal. Could be the cable you're using that cant handle the load

I was thinking about this. I tried the usb-c -usb-c cable that comes with the box on other chargers and sadly this didn't change anything.
Think you need the proper cable and proper PPS configs on the PD brick to get this working.

Yes you are correct. A special USB-C cable with an embedded chipset (E) is required along with special PPS. At this early stage I'm not certain many (if any) third party vendors meet these requirements. The only safe bet is the Samsung- branded one.

CONFIRMED !
i have a aftermarket 45w home charger and aftermarket 45w power bank.
both WONT charge at 45W, it charging like 15W.
when i plug in the stock 25w charger, it charging faster.

I have an Anker duel charger that has 45W USB C and a USB A. The USB C is rated at 45W and the USB A is rated at 15W. The 25W charges faster than the 45W. (at least what I am seeing)
Good info about the special cable. If we need a special cable... Where do we find it?
I do have to say, it charges fast with the 25W one.

Which if the charger doesnt support it. Then it would default to the lower one.
I.e.
If your charger is 5v 9v 12v 15v
But the phone needw 10v
It would default to the 9v.
Cant remember where i read this. But was a prerelease testing

The safe way to go is to use the samsung official chargers, that are precisely tuned for this, I would not risk a brand new somewhat expensive device

What is this telling me? phone says fast charging.
Using an Amazon Basics 60watt PD charger.

Another screen shot

yeah the phone claims it is rated for 10V at 4.5A and most 45W chargers use 15V at 3A, so likely to be nothing on the market fully capable of charging at super speed at the moment.
as for the USB cable it is a subset of USB 3.1 Gen 2, basically you need a cable with a chip in it, that chip allows you to break the 3A limit on standard cables. I've ordered this as I wanted a longer cable for my standard charger and should work with the 45W if I get it down the road. https://www.amazon.co.uk/gp/product/B073RY5JZ3/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

Now try this with the 25w charger in the box and you should notice shorter charge time remaining in the notification.

the cables i listed are what I use now. I have a 1TB 12.9 ipad pro and picked up these cables to use with its fast pd charging.
this charger:
https://www.amazon.com/gp/product/B07TC53ZYD/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
is not PPS but it does have 9 Volt at 3amps. i tested it with one of my note 10s and the ipad from 10%. im using a 60W anker brick for the ipad:
https://www.amazon.com/gp/product/B07BQJWDRM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
and the newer ravpower brick charged up much faster. again not pps (pdo) but it is fast in my less than scientific testing.

I'm just gonna use my $200 Samsung pre order credit to buy several oem or 45 watt chargers.

How? I ordered one on 8/27/19 and it's not expected to be delivered till 9/26/19. It went out of stock like a day after I ordered. It's not even showing available on Samsung.

You might want to check to make sure you actually got the 45w charger as it's been out of stock since about 8/28 - 8/29.

25w car charger

Did anyone find a good fast car charger?
Sent from my SM-N975U using Tapatalk

Try any type from Anker. As long as it has qualcomm fast charging, it is fast enough. Only a couple minutes behind stock samsung charger.

I have advice for you.

Edit From My Post Below. As I looked more into this, my wall charger that came with my phone is just a small 25w box EP-TA800 which I don't understand why accubattery says its getting 5,000+ mAh from it but needless to say the baseus car charger below is able to supply the 25w means while my Anker charger doesn't https://www.amazon.ca/Anker-Charger...rger&qid=1575374418&smid=AREE309N4XPXI&sr=8-5 . It looks like I need a new cable to make this 45w thing to work, if it even works with baseus. but still better then the pixel 2 xl 16.3W charging speed. But even if one where able to achieve 45w charging speeds. It would only be good for the first %50 the rest cuts down in speed.
The Baseus 45W Quick Charge 4.0 3.0 USB Car Charger For iPhone Xiaomi mi Huawei QC4.0 QC3.0 QC PD 6A Fast Charging Car Phone Charger from https://www.aliexpress.com/item/33020251902.html?spm=a2g0s.9042311.0.0.27424c4dO0uWdy "usb-c version" seems to be working good. Provides the full 5 Amps just like the one that came in the box with the phone. I even got the baseus red 2m usb-c cables. I'm not sure if its a fluke or if there any good at all.
I Do Not Know if it will be just as good but, I just ordered the cheaper version https://www.aliexpress.com/item/32970589225.html?spm=a2g0s.9042311.0.0.a30b4c4d1oAVXd without the display usb-c version which I won't see for another two months due to shipping. Unless its being shipped by ePacket which only takes a week or two to get the item. Also got the same charger https://www.aliexpress.com/item/33042906407.html?spm=a2g0s.9042311.0.0.27424c4d0fTcdC from a different vendor
I did however ordered the car charger originally for the oneplus 7 pro thinking it was going to charge that sucker up very fast but it didn't and i wasn't going to spend over 50 bucks for a car charger

I actually got it too from ebay and can confirm it works just like the original charger, I think it might be actually charging up to 45w.

It seems to achieve the 15 / 20 volts, I'll need to be on a 24 volt system. I'll have to wait has my battery on my phone is only 54%

The charger said 26.2V, 9.32V and, 2.75A and its able to support 15V at 3A and 20V at 2.25
Supplying 24V to the Baseus car charger, it only supplied 9.32V X 2.75A = 25.63‬Watts which is about the same just using 12V
My current cable only supports PD 2.0 60W, 3 Amps
The 100W cable says it can do PD 2.0 with Gen2 https://www.aliexpress.com/item/329...chweb0_0,searchweb201602_6,searchweb201603_52
Not all cables are the same. But i'm calling this as a good 25Watt charger with cable combo just untill it burns out

Its pretty crazy that Samsung chose the latest PD 3.0 variant with PPS, requiring the odd 10V at 4.5A. Clever heat management, but until now I came up empty finding the exact supporting charger other than the Samsung original who also seems to have its challenges. This article is pretty clear https://www.gsmarena.com/dont_just_..._for_the_samsung_galaxy_note10-news-38837.php
Not that I really would want such a fast charger to become my daily driver, fearing added wear on the battery, but for the rare occasion where I really need juice and do not have a powerbank handy, following if the community finds any solution.
