Quick Charge 2.0 or 3.0 portable charger for Note 4? - General Questions and Answers

Hi everyone, So I have a question. I have a Note 4, which has Quick Charge 2.0 technology. I want to get a battery pack that makes use of this. There's an AUKEY 20000 mAh that's QC 2.0, and one with QC 3.0 that's only about $5 more.
Here's the AUKEY 20000 mAh and QC 2.0:
Quick Charge 2.0 AUKEY 20000mAh Power Bank Portable Charger with Lightning Input for Samsung Galaxy S7/S6/Edge, LG G5, iPhone, iPad, Nexus 6P & More https://www.amazon.ca/dp/B01DPE8WZW/ref=cm_sw_r_cp_apa_FLaHxbVR7KR1W
And here's the AUKEY 20000 mAh and QC 3.0: [Qualcomm Quick Charge 3.0] AUKEY Quick Charge 3.0 20000mAh Portable External Battery Power Bank Fast Charger ( 74wh /5V 9V 12V Support for Input & Output ) for Samsung Galaxy S7, S7 Edge and more https://www.amazon.ca/dp/B01DPEW5ZA/ref=cm_sw_r_cp_apa_7MaHxbGMFTJ1J
First, will I see a difference with QC 3.0 over QC 2.0 on my Note 4 that's decent enough for the extra $5? I mean, $5 is not a big deal anyway. Second, I'll want this for my future upgrade too, so wouldn't it make more sense to go with QC 3.0 anyway? Might sound like an obvious answer but I'm looking for something more substantive than "yeah it makes sense". My phone is battery hungry, and takes FOREVER to charge if I'm not using a fast charge enabled charger, so this is an important aspect to me as well (and considering I'll be sticking with Note or going to Edge Plus in future upgrades, this won't change).
Suggestions for a different portable charger that allows for fast charge are welcome (at least 20000 mAh though), or simply advice on which of these two are better (the price is decent, and I'm not willing to go much higher than these prices)
Thanks so much! :laugh:

Onite 5V 3A Universal quick wall charger for Note 4

If you have a Nexus 6, Moto X, Galaxy Note 4, or any other Qualcomm Quick Charge 2.0 compliant phone or tablet, you need a high output “Super Charger” like this one to get the full charging speed that those devices are capable of. On my new Nexus 6, this charger took me from 30% to 92% in 30 minutes of charging!
Pros:
+ Fast and powerful.
+ It runs silently.
+ Good quality build, including a nice quality cable and plug.
+ Quick Charge 2.0 compatible.
Cons:
- Bulkier and heavier than most chargers.
- The LED light is much brighter than it needs to be.
- The prongs don’t collapse, so they are at risk of getting bent in your laptop case or bag.
This Onite 3.0A is well made and very powerful. I strongly recommend you get this or another 3A charger like this if you have a Quick Charge 2.0 compatible phone or tablet. I received mine for free, to review, but am very happy with it.

Am I missing something. I'm not using the "quick charger" that came with the Note 4, but shouldn't chargers ALWAYS run silently?
Thats not a quick charge 2.0 charger, the quick charge chargers use 9v's to charge instead of 5v's

Spammer. He doesn't even know the technology enough to be a reviewer.
note 4 charger(quick charger) is 9v,1.67A instead of 5V
note 4 quick charger is 9v, 1.67A. Though 5V 2.0A is also OK, while no quick.
Considering 5V 3A, maybe it is faster than 2A. But the IC will prevent from higher current.
I actually ordered and tested this charger. It seems as fast as my other 2 Amp chargers. All of the reviews of this charger on Amazon are from other people who've been given samples from the seller. Don't waste your money on this charger.
I'd never buy anything from Onite. Spam threads from them, like this one, seem to pop up quite often.

Powerbank that support Quick Charge 2.0

Any good powerbank out there. At least a 10000 mah above.
To be able to use fast charging feature in Note 4.
Actually that sounds like it would be really cool if it exists, I'd also be interested in knowing if there's a powerbank that supports quick charge. I've held off on picking up a powerbank for a while now, but if something like this is even possible it would probably get me interested, it'd be pretty awesome to be able to just plug in to a backup battery and have it charge up the phone with quickcharge speed ;P I wouldn't be surprised to find out it's not possible though... Anyone know?
Think the dual voltage 5 and 9 volt needed for quickcharge wil be a problem to design a powerbank with a feature like that. I don't say it's impossible but probably won't be cheap or small formfacfor
Yea. Is cool if fast charge powerbank then bring out to fast charge note 4. Lol.
There is this compact power bank (and it supports quick charging itself within 3 hours - via 2.1A input - at least on paper)
APE MP5200Q on Alibaba (not aliexpress)
Weight: 132g
Input: 5V/2.2A
Outport: 5V/3.5A,9V/1.5A,12V/1.5A
3 output ports: 2 USB ports and 1 built-in micro USB cable
Over-charge/discharge, over-current,short protection
Quick Charge output port: output 9V/1.5A or 12V/1.5A on Quick Charge state
Battery Cell type: Samsung Li-ion 18650
Quick charge 2.0: Class A
and it looks good too!
the only missing thing to make it a perfect power bank, would be 15W wireless charging capability...
Please everyone do say what Power bank you have
& how much time does it take to fully charge a Drained battery
So we know which charges how many times, Once or twice or more ....
Thank you all
I have aukey quick charge the silver 10400mah model its charge lg g4 same as qc2.0 wall charger I have mah meter
I also have an aukey but the PB-T2 model 12000mAh. Have quick charge USB outlet and also a normal 1A USB outlet. Has a 2A microusb input for charging an a so-so LED light built in. A bit heavy and slightly longer than the Note 4 in size. Cons: I would have preferred a 2.1A instead of the 1A USB outlet for fast charging other non quick charge devices.

As above Aukey Quick Charge 2.0 external battery packs are pretty good. They do them in different sizes and go above 10000mah
BlitzWolf looks good.
banggood.com are doing pre order, to be sent out 20th November.
From a store rep..
We use the newer chip FP6600 that not only supports QC but also standard fast charging, the Aukey does charge at QC speeds with their THY100 but will not fast charge other devices such as your iPhone at fast speeds. BlitzWolf's newer IC provides compatibility beyond just QC devices. The battery of the BlitzWolf is is LG and also of a higher standard than Aukeys domestic Chinese brand batteries. In terms of safety and compatibility this is one step ahead of Aukeys 6 month old version.

Hmm... we have Note 4's a removable battery is more compact and supports quick charge. Just have to get a battery charger that supports it. There would also be less power loss because it would be more efficient than transferring energy from one battery to another. Just my opinion.

Car charger (non-wireless) w/ quick charge?

Any suggestions? I'm looking for something that can do the quick charging in the car, is that even possible? Can it be done with a dual port so my wife and I can use the quick charger at the same time?
http://www.amazon.com/Charger-PowerIQ-Technology-Samsung-Motorola/dp/B00M43S18Y/ - Would this one support quick charging in the car?
Also,
http://www.amazon.com/Anker®-Extra-Premium-Android-Samsung/dp/B00NPP7TVU
This is basically the same cable that came with my S6 just longer correct? The included cable is too short to plug in near my night stand.
Any charger that is a 2amp charger... and any cable.. i have tried all my old cables on the s6 charger... all allow fast charge... and its charger is 2amp.... same as nexus 7 and all other newer devices... so just go with a 2 amp charger and enjoy the fast charge. And yes they make dual port 2 amp chargers... usually 1 port is 2 amp and second one is like 1 or 1.4amp... i have 2 cheap ones from amazon myself... will test them with the phone tomorrow and update you.

any cable will work, but not every 2.0A charger will work. i tested it with a 2.0A (not the Samsung one) charger and "fast charging" did not show up in the phone.
AFAIK, you have to use one of Samsung's OEM chargers or one capable of the Quick Charge 2.0 standard for adaptive fast charging.
OP, i only did a cursory search, but i found this dual Quick Charge 2.0 charger that might meet your needs: http://www.amazon.com/dp/B00TGD79X8?psc=1
Interesting, I didn't think to check for QC 2.0. I was thinking the Anker one did that. Thanks!
That being said though, anyone have experience with any of them with how they hold up?
Verizon sells one, it is their generic branding, it's the only one that I have seen or tried that is marketed that it is QC 2.0, works great even has a built in LED flash light basically. Sucks that it is $34.99 though.

From my understanding Quick Charge 2.0 is a Qualcomm Snapdragon 801 (or newer) processor feature. The Galaxy S6 is running Samsung's Exynos 7420 processor which features Adaptive Fast Charging. I don't know how they vary in terms of performance, but I do know that when I plug in my Quick Charge 2.0, my S6 recognizes it as a fast charger. Battery went from 40% to 63% in 13 mins so I'm assuming both charging standards are compatible lol..
Try this car charger, worked great for my Qualcomm based phones.

i'm reasonably sure it's the same standard. the Note 4 (Snapdragon 805) is listed on Qualcolm's website as compatible with QC 2.0. however, if you look at Samsung's website, it only lists Adaptive Fast Charging. Samsung just rebranded QC 2.0 as their own Adaptive Fast Charging. you can use all devices interchangeably.
also, the OP wanted a dual port QC 2.0 charger. that one only has 1 port w/ QC 2.0
I have already Anker 2 amp car charger in hand and i was thinking it wont be fast enough , i have seen video where quaclom demonstrated that Quick charging is faster than 2 amps charging , and judging by the fact that Samsung is providing comparable charging time with stock charger i was thinking that it is more than 5V 2.0 Amps .. too bad i am waiting for my phone to arrive.

I saw the Aukey 3.0 charger it became available a day or two after the Tronsmart charger. I have an Aukey qc 2.0 wall and car charger which are both excellent. I went ahead and ordered the Tronsmart charger I listed which is also qc 2.0/1.0 compatible, I should have it tomorrow. I wanted to compare the build quality between them.
Both have proven track records so more than likely either one will be a safe bet regardless of which one you choose. I'll post a follow up once I receive it!

Looking forward to your thoughts on it. I have a Tronsmart QC 2.0 car charger, very good quality.
I also noticed that the Tronsmart includes a longer USB cable, which is nice.

Hi
The Tronsmart qc 3.0 charger is very solidly built and smaller than I expected, it is close to the same size as my Aukey 2.0 quickcharger although it feels slightly bigger in the hand due to the the defined edges while the Aukey is rounded on either side and relatively flat on top and bottom.
I don't have any qc 3.0 devices at this point to be able to give a comparison of charge times between the qc 3.0 and 2.0 charging, although I don't have any reason to doubt the quoted specs since the qc 2.0 times have proven to be correct over time.
I will say that anecdotally there does seem to be a little bit of a difference when charging a qc 2.0 phone with the Tronsmart 3.0 charger, and that is that it seems to take slightly longer to charge the phone when compared with the Aukey 2.0 charger but the phone doesn't seem to get as warm when quick charging.
This wasn't a scientific test just a general observation, so your mileage may vary, I hope this is helpful. I can say that I wouldn't have any problem recommending Tronsmart or Aukey chargers going forward they have similar specs and are both priced competitively.
I cancelled my HTC one a9 pre-order after the shipping was delayed, so I'm not sure when I will have a qc 3.0 device to test it with.
Just bought the Tronsmart QC 3.0 and it came today, and Quickcharge 3.0 isn't as fast as I expected it to be... I got home from work and did a little experiment, Phone was at 6%, and as I plugged it in, I set a timer. 32 minutes into charging, my phone (HTC One A9) was only at 43%. Much slower than I expected... 37% in 32 minutes, nowhere near the advertised speed of 85% in 35 minutes on a 3300mAh battery. Airplane mode was also turned on while charging.
Would not recommend.

I have read some news that the early version of HTC One A9 just comes with QC2.0 support, but a future software update will bring the QC3.0.

Even at qc 2.0 speeds, it shouldn't be charging at around 1% every minute right? or am I wrong. When I saw the quick charge statistics of 60% in 30 minutes, I imagined around 2% a minute

That fast charge 0-60% in 30 min is the test done by qualcomm in the lab. Actually there will be some errors between different devices which support QC 2.0 technology.

No I don't have a current meter that can measure USB currents. It's only 1% a minute when charging my phone. Quick charge is way too hyped up.
I always look into verified purchaser ratings in amazon while buying anything. I found the following Quick Charge 3.0 which (brands) are listed in qualcomm website (website doesn't have 3.0 listing of accessories, but these manufacturers of accessories are found:
1. JDB Quick Charge 3.0 18W USB - $26.99 (61 customers - 5stars) - http://www.amazon.com/Qualcomm-JDB-...860&sr=1-6&keywords=qualcomm+quick+charge+3.0
2. Anker PowerPort+ 1 (Quick Charge 3.0 18W USB Wall Charger) - $25.99 (45 customers - 5 stars) - http://www.amazon.com/Qualcomm-Anke...860&sr=1-1&keywords=qualcomm+quick+charge+3.0
I am still waiting on my HTC A9 pre-order to be delivered, would pick any of these. If anyone bought either of these please give me your opinions on these. By the way, has A9 received the update that would support quick charge 3.0 yet (it was told that, the new s/w update later in the year would support QC 3.0)
Edit: Also found this one for $15, and it says qualcomm quick charge 3.0. Looks very cost effective, but none of the review highlight on QC 3.0. Did anyone try this? http://www.newnow.com/products/tc-0...INWCtxjqipuNSxwZhGJVeE3T1EaAjWI8P8HAQ#proDesc

I bought this same charger too and I'm with you, doesn't seem any faster that my regular charger. the Anker 3.0 wasn't listed (or I missed it) when I ordered the Transmart or I would have ordered that one instead.
i'll check the voltage & amps in GSam next time I charge to see what it says.
I bought the JDB QC 3.0 charger on eBay from China for $18 (also available on AliExpress for $14). It seems like a good deal and good quality if one can be patient.
I do wish those of you posting performance comments would hold your water until your phone actually supports version 3.0; until then the 3.0 chargers aren't likely to be any faster with 2.0 phones (e.g. the A9 with current firmware).
FWIW the 3.0 spec defines charge voltages every 0.2V from 3.6V (some places say 3.2V) all the way up to 20V. That does not mean that all chargers offer this range, or that all devices can use these voltages (the phone determines which of the available voltages to use through time). The 2.0 spec only had a few charge voltages to choose from so the more granular voltage choices with 3.0 should be a win for all devices. All of the chargers mentioned so far offer a top voltage of 12V at 1.5A (compared to HTC's 2.0 max of 12V at 1.25A). At 9V there is 2A available (compared to 1.67A for 2.0). In the range around 5V the different products list different currents between 2A and 3A but at this stage I suspect the spec differences are probably not real (2.0 is 1.67A for comparison). So potentially 3.0 can provide up to 20% more current than 2.0 across the voltage range. In practice the greatest benefit will be to devices with large batteries (i.e. not A9) as they can absorb charge faster - it is quite possible that the A9 will not benefit from the higher available currents at all (but still benefit from the smaller voltage steps). I look forward to getting real world measurements.

I just did a little experiment with my HTC one a9 and my old iphone 6. I used both till they are the same battery level (16%), and (With airplane mode on for both devices) I plugged my HTC to the tronsmart qc 3.0 adapter, and my iphone into the HTC charger that came in the box. A little while later, I checked the percentages and they were exactly the same. Either my HTC is charging at conventional speeds, or the iPhone charges at the same speed as Qc 2.0 (Roughly 1% every minute), Never owned a Qc 2.0 device so not sure if that's the normal speed... Anyone have any input on this?
It's not just comparing apples and oranges, there are multiple differences: battery capacity, age, and charging regimens available in both phones and chargers. I don't see any comparability. As for charging regimens, the new A9 is a QC 2.0 device (for now) charging on a QC 3.0 charger, which means the CPU will only request voltages that are available in QC 2.0 and only with slightly higher amperage available from the charger (which may not even be usable with the A9's small battery). So I expect little or no improvement over a QC 2.0 charger. We will have to wait for a test of QC 3.0. The iPhone uses Apple's own charging regimen, which usually doesn't charge fast unless connected to an Apple charger, or one able to act like one. I suspect the QC chargers have that ability, as it is increasingly common, so the question is how much current is available in the charger for the Qualcomm implementation of the Apple protocol?
I think the identical charging times is just an accident.

If you owned any HTC Phone since One M8 series, all of them came with QC 2.0 charger, including the A9 bundled charger

So you're saying that QC 2.0 is supposed to charge at 1% every minute? That's very slow compared to Qualcomm's advertised speeds. And if the iPhone 6 charges at the same speed as the HTC One A9, then does that means the iPhone supports QC 2.0? I find that weird because Apple's specs say nothing about quick charging.

I am not sure if it is 1% per minute. My M8 charges 70% in an hour. QC 2.0 is the technology of qualcomm and nothing to do with Apple. Apple doesn't use the the qualcomm technology but they have their own, and advanced Apple iPhones have charging capacity similar to QC 2.0 . QC 3.0 is going to be the new technogy when qualcomm makes it available through HTC update, which we are expecting to be a great upgrade (which is not available on A9 yet, though the hardware is all set to do that)

Quick charging or not?

Need to buy a powerbank, pondering between the Anker PowerCore and the PowerCore + (10000mAh version). Only about 10 euros difference between the two. Is it worth it? Does quick charging do anything bad to the battery?
BTW, the 3.0 version of the charger costs as much as the 2.0 for some reason (at least where i live). What happens if i use my LG V10 on that? Does it work as a 2.0 charger, or will it become just a regular charger?
As long as it is Qualcomm certified you will be fine. I would get the one with Qualcomm 3.0 tech
I have Power core+ 10500 and I like it.
It does express charge both ways!
Samsung Adaptive Fast Charger will work in express mode.
QC 3.0 will not work for the V10 as it has a snapdragon 808 processor. The 820 and a few others will work for 3.0. I would stick with what is designed for this phone before risking the chance of damaging the battery. I looked into this a few weeks ago before buying a 2.0 car charger for my V10.
While the phone is only made for a.c. 2.0 I would still get the 3.0 charger for future proofing the purchase. A good charger, as well as the phone processor itself, will distinguish the charging limit and power accordingly. At least this way if your next phone is qc 3.0 you don't need to buy another charger.
The question is though is 3.0 backwards compliable with 2.0 devices as will the charger charge at 2.0 speed
I believe QC 3.0 can also do QC 2.0, at least it does on my Note4 and S7. I have a QC 3.0 car charger
