[2/23]Updated:
Although S7 uses the Snapdragon 820 processor(Most other regions use Samsung Exynos 8 Octa), sadly only features Quick Charge 2.0(please check Qualcomm news:https://www.qualcomm.com/news/snapd...-galaxy-s7-and-s7-edge-powered-snapdragon-820
So I deleted all the quick charge 3.0 product links. If you guys want to find the quick charge 2.0 products, you can visit their official website:
Tronsmart:http://www.tronsmart.com/products/quick-charge-2-0-chargers
Anker:https://www.anker.com/search?keyword=quick charge 2.0
Aukey:http://www.aukey.com/category/Power
Choetech:http://www.choetech.com/Product-search.html?keyword=quick+charge+2.0
For the car, I guess I'll go for Aukey 49,5W 3ports
I recently received the CHOETECH qc 3.0 wall charger to test out and review. I gotta say I love their products. I have a fast wireless chager, a qc 2.0 power bank and the qc 3.0 wall charger. While I don't have any qc 3.0 compatible devices her, this wall charger is awesome. It's very well made, sleek, and charges as fast as the OEM charger from ssung for my note 5. Love love love CHOETECH and all their products and this new wall charger promises to be of the same great quality I have come to know and expect from CHOETECH. Highly recommended!
Picked up a Choetech Quick Charge 3.0 charger and compared w/ the 2.0. It's super convenient to charge 0-100 in no time. Quick Charge as most of you know, allow for high levels of current to flow to the battery, in an attempt to maximize its charging efficiency. Quick Charging also tend to charge their batteries at higher voltages, allowing for a higher rate of power transfer through commonly found cables. The downside to all this is that it can limit the life of your battery since they get hotter. This is the BIG selling point between 3.0 and 2.0, not necessarily charge times but battery life over the long haul. Different batteries require different charging voltages and QC 2.0 supported four modes at varying power levels, 5 volts/2amps, 9V/2A, 12V/1.67A, and a 20 volt option. QC 3.0’s uses voltage between 3.2V and 20V at 200mV increments, allowing for a wider selection of voltages.
This is useful as it reduces the amount of energy wasted during charging. Wasted energy is a big deal because all that extra power would be lost as heat. See, that's what makes the battery run warm thereby limiting the longevity of the battery's life. By having the wider range of voltage you waste less power and that results in less heat, which for you means longer battery life a year from now.
When I tried this with the Note 5, I didn't notice a significant increase in charging time but I did notice less warmth on the back of the phone. Does that prove it's working? I'm not sure but if the option exists, I'd rather try to extend my battery life if possible.

I just check Qualcomm official website. Now only Anker and Tronsmart are certificated by Qualcomm (Quick Charge 3.0) among the above brands. https://www.qualcomm.com/documents/quick-charge-device-list More and more accessories brands will release quick charge 3.0 products in 2016.
I reviewed the Tronsmart QC 3.0 you have linked in the op. It's a quality peice and even charging my QC 2.0 LG V10, it's a lot faster than the oem charger.

CHOETECH QC 3.0 18w adapter
Hi Everyone,
Just got this charger for my Note 5 ( and soon to own nexus 6P) and I love it! Its awesome to have an additional fast charge with me at work and at home. Now that I have the Note 5 and there is no removable battery I am always plugging in so having an extra Quick Charge at work is great! One of my biggest fears after reading these forums for so many years has been battery management and using the correct plug with each device that I own and with this being Qualcomm 3.0 but reversible to Quick charge 2.0 I Love it, I just carry one plug now (actually I just leave it at the office) and use it for multiple devices! I know you all know that Choetech makes a great product as I have referenced this forum in most of my decision making, and have since purchased many items form the company including the Fast Charge Qi Wireless Charging pad ( I did not get the additional quick charge cable option as I just use my Note 5 plug) but this Charger works great with the Qi Fast Charge Wireless Pad as well if you are in the market for one and if you buy them separately it is not that much more money, to me it was definitely worth it!
With that being said, your forums have helped me for many many years and I just joined and starting writing, so please feel free to let me know if I can answer any questions about this product or any product that I may have. I really love these forums, and I am very happy to be a part of them!
Thanks!
ChoeTech 3.0 Quick Charger
I had the opportunity to review the ChoeTech Quick Charge 3.0 wall charger and I have to say that I am really impressed with the upgrade from the 2.0. I’ve been using the 2.0 for about two months now and I LOVE the rate at which it charges. I would have to say that the most impressive thing about the Quick Charge 3.0 is that I get to 50% battery at bout 7-10 minutes faster than I do on the 2.0! I used to only get to about 35-40% after a 30 minute charge but with the 3.0 I am hitting nearly 50% in 35 or so minutes! Needless to say, I have been very impressed. Another feature that I’ve kind of been raving about is the fact that the USB cable can be entered into the charger block UPSIDE DOWN! I can’t tell you how often I have to fumble around in the dark before bed trying to get the cable back into the charging block (and we all know we put it in the wrong way first EVERY time) but now I just put it in no matter the direction and it just works. Not to mention, the charger comes with a USB-C cable and while I don’t have a phone that requires one, I am glad to have one as I suspect I will one day soon. I truly couldn’t ask for more! Great product, works perfectly. I’ve become a real fan of the ChoeTech products and look forward to seeing what other awesome things they come out with soon!

I can now STOP using the OEM charger which is crap!
Admin: Please add this to the list of working prime accessoriesMy first transformer Prime had charging issues, ( would not charge intermittently) and I found the OEM charger that ships with the prime to be sub-par.. So:
After checking out NUMEROUS threads, I just purchased the following charger and USB adapter from Radio Shack to Use with my Prime:
This particular model has been confirmed to work on the original Transformer-
Enercell AC to DC power adapter 12vdc 1.5A
Radio Shack Model # 273-358
http://www.radioshack.com/product/index.jsp?productId=3807944
used together with this USB adapter:
Model #273-227
http://www.radioshack.com/product/index.jsp?productId=3643549
Does anyone know if the above Enercell 12V 1.5A charger should work on the Prime?
see post #104 here in this thread:
http://forum.xda-developers.com/showthread.php?t=1087321&page=11
Also, can someone confirm the Tip polarity I should use? (I believe the prime uses Positive tip polarity just like the original transformer did?)

Simple Guidelines to Prolong Lithium-ion Batteries
Do not discharge Li-ion too low; charge more often.
A random or partial charge is fine. Li-ion does not need a full charge.
Limit the time the battery resides at 4.20/cell (full charge), especially if warm.
Moderate the charge current to between 0.5C and 0.8C for cobalt-based lithium-ion. Avoid ultra-fast charging and discharging.
If the charger allows, lower the charge voltage limit to prolong battery life.
Keep the battery cool. Move it away from heat-generating environments. Avoid hot cars and windowsills.
High heat and full state-of-charge, not cycling, cause short battery life in laptops.
Remove battery from laptop when used on the power grid.

Taking 2 hours to charge implies a 0.5C charge rate.
What's the rated voltage, current and wattage of the stock charger anyway?
Please note that the above charger won't work overseas. It's only got 110V.

Stock charger is rated 15 volts DC @ 1.2 Amps
This radio Shack charger That is working for me is rated 12volts DC @ 1.5Amps.
I read the Transformer specs required to chagre are 11V to 15V DC @ 1A to 2A max
This charger fits within these specs, so that is why it works pretty well. The TP and the charger itself do not get hot at all, so I don't think this is causing any issues with the battery. Does anyone think a slightly quicker charge time will harm the battery long term?
Li-Ion Batteries are sensitive to fast charging. While it is within specs, your long term battery life could be affected. There is probably a reason that Asus decided to stay at the very bottom end of the spec.

I have done additional research due to above feed back in regard to Li-Ion's sensitivity with faster chargers.
Apparently, you are correct in regard to long term battery life concerns. I have only done 3 charges so far with the Radio Shack charger. I will let it drain down and switch over to the stock for now and just keep this other one as a backup. Is charging at 300MA more than OEM that much more of significant concern?
Better safe than sorry. Hopefully the few charges I have done did not cause any harm.... If the stock charger goes bad again though, I don't know if I would buy another one....
What was interesting is how hot the stock charger becomes in comparison to the radio shack model, which barely gets even warm. I always was a believer that more heat means less efficiency, so I'm somewhat confused, but I don't want to risk shortening the battery life, so I will go back to OEM stock charger for now, but reluctantly.
I wonder How these "alternative" chargers have effected the batteries for others with the original transformer?
That's an expensive charging setup... nearly $40 eek

I wouldn't worry if I were you. What you bought is just an adapter with a USB socket. The part which decides how to charge the battery is inside the tablet. The requirement for the adapter is to have the same voltage as the original one and at least as much current ( meaning 1.2A or more). The tablet will only take what it needs.

It's always easy to scare people. It does say in the description of the movie that he did it by removing the protection circuit. They are designed with protection, so of course they will blow up without one.
Dude why so serious?
It was a joke thus a smiley was implemented. It is quite difficult to do that to a battery. Although I have seen some insane people in the RC hobby community destroy expensive cars and helicopter this way.
Lipo+ignorance=Hollywood style explosions
I saw the smile, don't worry. It is just that most of people, especially when they do not have the knowledge about something, tend to see the bad part (I'm also guilty of this, not in this domain though ).
So, it was not anything against you, the video is entertaining. I just wanted to put people at ease.
Charging Issues
It does not matter the type of rechargeable battery, any "quick charge" will reduce the battery life. I personally don't think 300mA is that much of a difference, but am sure the battery life would be reduced somewhat over time. Nor would I worry much from just 3 charges.
However I don't think we should have to shell out an additional $40 just because Asus can't build quality components. Mine quit charging consistently yesterday (week and a half). I guess we can put it in the same category as GPS...non professional and spotty at best.

So I have started using an application on my Note 3 that is pretty much a battery muncher, GPS, Data, Processing, Graphics the works. I am looking into some options for extending battery life with some accessories. I was originally planning on getting 2 batteries with a charger but I'd like to also consider a portable battery pack so I can share the power with friends. What I am curious about is whether or not the charger can support the 900ma/h charging rate. I was wondering if the standard usb port can support the power as long as its a micro usb 3.0 connector. To simplify I just need to know that if I have type A usb connector to a micro usb 3.0 connector can I charge my phone at the fastest rate. And does the output of the charger have to be at least 1A?

I own two battery packs. Both are from a company called PowerGen and I picked them up on Amazon.com. One pack is 12,000mah the other is 5,200mah. You just plug your regular charging cable into one of the standard USB jacks in the battery pack and turn it on. The larger pack has a 2A jack and will charge at a fast rate. When I was using the Note 2, I used a special heavy duty charging cable that I picked up on Amazon.com and that cable allowed the Note 2 to charge at a faster rate. I have not tried to use the cable on the Note 3, but I might soon. I feel that battery packs are a much more flexible approach than extra batteries. You can get more than one recharge on the battery pack. I addition, I use the battery packs with a large number of other devices. If you get a new device, the battery pack can still be used.

YUp. I have an old anker external battery with 1a and 2a ports, the 2a port charges my note 3 at 1800. To be fair it is picky over the cable used (a decent quality non ribbon cable) and the temperature of the phone and battery (thermal throttling which is perfectly sensible to avoid cooking the battery and phone). It appears that there is a lot of variables that can potentially screw up a decent charge rate for some folks some of the time. My experience with the anker battery pack has been excellent, even nearly 2 years later after daily use.
Personally I am getting a little tired of the whole charging the battery twice a day so I am looking at a larger battery. The zerolemon allegedly affects signal quality, the 6400mah ones from elsewhere seem to come with shocking cases so I am still looking. It would be great if samsung came out with an extended battery and case. You think they would be after that money.

How do you check what the charging rate is And id like a cable that bends with no resistance unlike the factory cable .
Theres a free app "galaxy charging current lite", seems to be pretty accurate compared to time taken to charge.
As for the cables. I checked quite a few cables and I noticed that the higher quality cables, more expensive, thicker, better connectors etc were far more likely to charge at a higher rate. I would not be shocked if some of the cheaper cables, especially the flat noodle types were skimping either in the cables or the shielding. I could be entirely wrong of course but I did attempt to limit any other variables like being in airplane mode, low room temp, battery not near fully charged.
Don't get me wrong, I find it a huge PITA using a stiffer cable but that is why I am looking for an extended battery that doesn't leave me with the worlds worst case or stuff up the signal.

2 a is not bad. That is what the oem charger is. Depending on how much juice the app is using 1a won't cut it.

Most phones only come with a 1A charger, while most tablets (and Note 3) come with a 2-2.1A charger. I have an Power Bank battery with a 1A port and a 2.1A port. The 2. 1A port is the only one I use to charge my Note 3, and I use the 1A port for other phones and/or my blue tooth headset.

Hi people
Since I'm part of the lucky people owning a Huawei Ascend Mate 7 (MT7-TL10), I'm actually looking some accessories like a quick charger.
I wish a charger better than the original one if possible, with EU pins, and with a good quality checked (I prefer to avoid some product with awesome specs but not tested ...)
So anyone have any idea where I can find a good charger, and without any risk for my phone ?
Thanks

for few days i went to jarir book store on KSA . I found Charger good price also 2 USB 5 volt 2.4 Amber ... compatiable with mate 7 and faster from orignal ...
just to know more fasting to charge wil damge your batter of mate 7 quickly .also orignal 2 A will damge
for me I charging with Iphone charge 1A good for batter and Stander and low risk to Device
If you want proper charging, then always use the accessories coming with that product. It is tested for sure and good. Other than that, you can use any charger delivering the same charge. The original charger is 5 volt, 2 Ampere. Don't use anything above 2 amperes as it may damage the device. Below that will charge it slowly.
BTW, why you don't want to use the original charger?

Is it safe for battery life of Mate 7?
I'm using a NTT Docomo Quickcharge 2.0 adapter and It does support it even though is not specified and it's not a qualcomm chip.

Can you test it with ampere (free in gplay) i don't think it will charge over 1800mA so that it acts like a normal 2a charger
Fast charging
Using a fast charger will destroy your battery faster. Not recommended as the battery is not removable. You can get a battery and if you are comfortable removing the back and swapping it out then go for it.

that is not correct as you are not connecting the charger to the battery directly. In fact the charger is just a power supply. The actual charger is integrated into the phone (charging controller).
In general you need to know that volts are pushed to the device by the power supply and amps are drawn by the device (phone) from the power supply. Therefor using a power supply with more than 5V will kill your phone but using one with 2A, 3A or even 4A will make no difference as the charging controller will just pull the amps required. Because of that you can not really fast charge a phone by changing the power supply only if the phone supports the fast charge option (for example some Nexus phones).
I tested this myself with a power supply (can provide 5V and 1.5 to 4 amps) and an amp meter. The phone always drew between 1.5 and 1.6 amps (with and empty battery, 8 to 10% left) regardless of the selected amps of the power supply. Using a power supply with less than 1.5A will kill the power supply as the phone tries to draw the 1.5 amps or more. As result the power supply will get hot and eventually die.
Since battery is not removable be careful with fast charging, since it will decrease the life span of the battery and in the end it will just give you less battery performance.. it is stupid... however.. there is situations where it can be really needed though but not on a regular basis..
Last weekend I would really had needed fast charging.. It forced me to spend about 3 hours on a cafee so I could make it 100% so I did know I did survive the day with gps and all other things.. However in these situations I really like the ultra power saving mode..it saved me that night.. when I was lost in stockholm.. and my phone was really the only way to get contact with people

Why don't you buy a powerbank? I can advice you the xiaomi 16000mah. That one charges fast and you can be mobile.
Any recommendations?
I wonder if a S6 charger do the trick. Stock charger is too slow damn. Spending 3 hours to have a full charge is not acceptable for me.
I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v and 2 Amps. Batteries will automatically lose cells from charge cycles and by the time you feel the effects of the battery going bad, you would have already moved on to the next device for the next person to worry about. And saying to use the Stock Charger isn't really good enough as the Stock charger doesn't serve as a Car charger also. If you want to charge your phone quick, and you already have a 2 Amp charger, Check your microUSB cable. Don't use junk cables, buy quality or use the cable you received with the device. You get what you pay for. Fast Charging won't work as the Charger has a chip inside that communicates with the Phone and Device. Also, when buying a charger, don't just randomly buy a charger online, Make sure its UL Tested. Even if it says UL tested, there should be a test number on that UL Label, take it a step further and google it and make sure it matches the charger specs and passes as knockoff chargers are notorious for copying other chargers Regulatory icons to make it seem authentic. You don't want to buy a junk charger that ends up burning your house down or gives you a very bad 120 Volt shock through the microUSB cable that would also kill and fry your phone.

You have not read my earlier post or you did not understand it. Changing the charger on the Mate 7 will have NO effect (zero, nada) on the time required to charge your phone except the charger delivers less then appr. 1.6A. Then it would take longer and evetually kill the charger. The Mate 7 uses a Kirin chip which has no fastcharge implemented. Samsung uses Qualcomm Chips with implemented fastcharge technology. The charger (in fact a power supply) and the phone/CPU/charge controller need to communicate with each other, otherwise fastcharge will not be activated (the reason fastcharge with charge-only cables does not work because they lack the required data cables for communication).

Wrong. Correct would be "I'm going to be honest, it doesn't really matter how you charge your phone as long as you don't go over 5v." The amps of the charger don't matter at all -> amps are PULLED by the phone not pushed to the phone. You could use a charger with 100 or 1000 amps and it would not hurt your phone a bit as long as it is only charged with 5 Volts.
More amps (>1.6A) on the charger do not improve the time for charging one second.
1.6A is nothing. i use 2.0A and it still chrges 3 hours.

Yes, and that won't change one bit even if you use the best and most expensive charger and a 1000$ cable. The Mate 7 is limited by its hardware (built in charge controller) and pulls max 1.6A. End of story.
As long as you don't understand how charging works you will spend 100's of bucks for cables and chargers to no avail.
The only reason, why charging with some charges is quicker than with others is that those chargers actually deliver the amps they are supposed to deliver. There are a lot of cheap/bad chargers out there which are labelled with 5V/2A but only deliver a fraction of the amps. You can identify those chargers easily because they get extremly hot. I use a 2A charger from Aukey which gets only lukeworm.
I have a nice collection of quick charge 2.0 chargers around the house, so this is a real negative blow if true.

It still charges very fast with the stock charger.
Old news by the way.
What do you mean "if true"? Google stated that in their reddit AMA and now there is an article with real world test data showing it. Are you still hoping it is all wrong?
Not a bummer at all, it's a GOOD thing. Proprietary Standard < International Standard any day of the week.

I was going to say this as well. Google is all about proper standards and not going proprietary (probably part of their "Dont be evil" motto). It will suck for a while since USB Type C is not widely adopted yet but soon enough it will be.
http://www.tomsguide.com/us/google-nexus-6p,review-3131.html
"Google claims that when the phone's battery finally dies, the Nexus 6P can recover up to 7 hours of juice from only 10 minutes of charging with the included charger. After 10 minutes, the phone's power level went from 0 to 32 percent. At the 20-minute mark, the phone had a 48 percent charge."
I see why they didn't bother with the expense of getting qc certification. This is insanely fast charging. The first 10 minutes is roughly 3% per minute! All I need now are 3rd party charger options and I know aukey, anker and tronsmart among others are working on it and I'm confident we'll see cost effective options available in the next month max.

So they tested a few. A lot of them worked, as in charging quickly, fast or "rapidly". Please read the article...tsk tsk...
It's a good thing I purchased a few Aukey and Tronsmarts that were just on sale recently. And I'm sure a lot of us jumped on those deals too, so a lot of us are good.

I don't know what I was thinking honestly. I guess I just wanted some other opinions. I know it will be all good down the road. It just sucks that I have a good 3 or 4 chargers that won't be able to get the job done as fast anymore. I did read the entire article, but it looks like they've updated it a couple times since.
Actually whichever phone you may get, there would be some missing features always. Better cope with it and wait for the next editions.
Quick charge, fast charge, turbo charge... It's all essentially the same..
The processor basically allows you to connect a high powered charger. It's like connecting a tablet charger to your phone..
The names are nothing but useless branding

WRONG
Quickcharge is more efficient with the same cable. Fastcharge needs a thicker cable to work the same.
/intentionally being vague and not explaining the electronics theory behind my wild claims in order to get a rise out of the un-aptly name sparky.
To add to this, USB Power isn't dumb.. there's a handshake involved where the device says what it needs. You can have a charger capable of 1.21 jiggawatts if you like, if it thinks the device caps out at 2A, that's what it'll send. It needs to understand the chargng protocol in use.

Not true,
Quick charge works by increasing the voltage, with varying charging profiles. The following are the profiles of the Nexus 6 charger:
Standard - 5V x 1.6A = 8W
Turbo 1 - 9V x 1.6A = 14.4W
Turbo 2 - 12V x 1.2A = 14.4W
The Nexus 6P power brick charges at 5V x 3A = 15W

You've probably heard of quick charging, turbo charging, adaptive fast charging, rapid charging, and Qualcomm Quick Charge 2.0 before - or at least one or two of these things. What you may not know is that all of them are actually basically the same thing, based on the same licensed technology from Qualcomm known as Quick Charge.
With that basic premise in mind, what I want to dispel in this article is the notion that you need an OEM-branded charger to get the maximum charging speed out of your smartphone, because this generally isn't true. And understanding that could save you a fair bit of money, especially if your phone doesn't come with a quick charger, or you need a second one for work or travel.

There might subtle differences between how google implemented it with the 6P vs the others but the overall premise is the same

That has nothing to do with charging over usb c... That's in regard to qualcomms tech being called different things by the marketing of different manufactures... motorola calls their turbo...
edit: There's a big difference between charging at varying voltage and current, than not. You can't really call them the same thing even know the end result is pretty similar

No, the whole point is that the OP can still use those chargers he already has and get the same result.
Good news folks.
The 5X has a QC 2.0 chip. http://9to5google.com/2015/10/22/nexus-5x-teardown-repairability/
The 6P likely has the same (we'll have to wait and see).
Now the question is when will the devices be certified and the chip enabled.

It is insanely fast. I have a Chromebook Pixel that uses the type-c connector. It's faster than both my turbo charger and Samsung's fast charger. Most of my connectors are the regular USB. I didn't buy a lot of QC chargers other than what came with my phones, and one Motorola turbo charger.
Funny, was just watching the 5x teardown - condensed version - and they mention quick charge 2.0 chip was there.
Then I was reading about the n6 for $270 on eBay, and they mention this about qc 2.0;
can regain six hours of power after 15 minutes of charging with Motorola's special turbocharger that features Qualcomm Quick Charge 2.0 technology.
We get 7 hrs with 10 min charging time on the 6p, with a bigger battery.
Guess which I prefer to have .....
the bottom line is how long will it take from 0-100% charged
So I've been able to test out this nice USB car charger from Choetech Official with Qualcomm 2.0 charging capabilities. And I must say this lil thing works very well. Charged my Nexus 6 up from 15% to 73% around 45min. It's a well built charger that has smart technology for recognizing what kinda devices you have plugged in.
Has a dimmed LED that changes from blue to green when you plug up a fast charge device.
It's a dual USB port charger.
Input: 12-24V
Output 1: 5V 2.4A
Output 2: 5v 2.1A/9V 1.7A/12V 1.3A
I really like this unit. Works better then the crappy one i used to own by Qmadix. That one always seem to stop working after 2 weeks of use.
[Quick Charge 2.0 Car Charger]CHOE 30W (with Most Powerful QC 2.0 Port) Dual USB Car Charger with Micro USB Cable(White) https://www.amazon.com/dp/B00YX7Y3G8/ref=cm_sw_r_other_awd_GxKlwbPTT27F2
PS. the Choetech C0046 does come with nicely built 3ft USB cable.
I received this charger couple weeks ago and have been using it. The charger arrives in a nice package with the standard accessories. Inside it has the charger, the usb cable, instructions manual, and a pamphlet that ask if you're happy with the product or not. Pretty standard nowadays. I got the black charger but they also offer it in white. The charger is shorter than my other ones which is a plus for me. I don't like them to stick out of my car port since it's really close to my shift knob. The charger comes with two usb ports. 1 is for quick charge 2.0 for some phones like my galaxy note 5. The other is a normal port that charges pretty fast too, up to 2.4 amps. You can use either ports to charge your devices and they will charge to the max allowed but if you have a quick charge 2.0 enabled device, it's best to use that port. They colored the port blue for fast recognition which is nice. I don't have to fiddle around with it while I'm driving to figure out which port it is. The quick charge can charge my phone from 50% to close to full in about 45 mins. It takes longer if the phone is being used. I use the charger daily during my drive to school. I always charge it up to 100% before I head to class so it can last me all day. I was worried that by using quick charge so often, it would deteriorate my battery life but I haven't experienced that yet and hope I never do. When I use the charger to charge 2 devices, they both charge at their max. My phone charges with the quick charge while the other phone charges with the other port and it doesn't affect each other, which is very good. I really love this charger. If Iphones had quick charge, I would buy this charger for everyone in my family.
Choetech also was nice enough to allow me to test one of these charger for them.
I found it to be an excellent charger.
I have copied my review from amazon here for the fine folks here at XDA.
I will try to answer any questions you may have, just post up a reply or send me a PM.
--------------------------------------------------------------------------------------------------------------------------------------
This is a great little charger, and I do mean little.
The size actually surprised me a bit considering this is a 4 port charger.
I expected this to be a huge block sticking up from my 12v car port, but it actually is a nice small charger.
I have 2 port chargers that are bigger than this is, enough about that, on to the review.
Looking in the package you will find:
The Choetech 4 port Quick Charge 2.0 certified charger
3' USB cable
Instruction manual
The USB cable is one of the best ones I have received with a charger in a while.
It is not thin and flimsy like you usually get.
The charger itself is made of a nice gloss black plastic and looks and feels like it will hold up well to years of abuse in your vehicle.
This charger does support Qualcom Quick Charge 2.0, meaning that it will auto adjust voltages and amperage to best charge you compatible device as quick as possible.
In testing I found this charger to be able to charge my LG G4 and Samsung Galaxy Note 5 in about the same time as my other Quick Charge 2.0 certified wall chargers.
This will also charger non Quick Charge 2.0 certified devices at the maximum rate they will allow.
I tested my LG G3 that is not Quick Charge 2.0 certified and will max out at 2.1a charge rate.
It got 2.0a charge rate from this charger which is great.
There is also a blue LED on this to help you find it easier in the dark.
The LED itself is dim as to not be distracting,
I have attached some pictures showing how small this charger is and me using it to charge multiple devices including 2 phones and a GPS unit.
I have had zero problems with this unit and am glad to have it.
I would recommend this to anyone with a car or truck and either multiple devices they need to use daily or a device that is Qualcom Quick Charge 2.0 certified.
If this review has helped you at all, please click thanks below to let me know.
I received this at a discount in exchange for an honest review, this does not change my opinion of the product in any way.
Hey guys,
I got to use this charger too. Having 4 ports, one with quick charge was really handy. I was able to charge my Nexus 6, Nexus 9 tablet, and an iPhone 5S all from the same charger without having any drop off in charge rate from any of the devices I could measure with Ampere (Nexus 6 & 9). Overall, there isn't much more to say that the other guys above didn't say.
Other thoughts:
It's really small. This thing packs a lot of power for its size.
It is scratch and finger print prone, but I plan on leaving this in the car all the time; so that doesn't really affect me.
The charging light changes color based upon normal charging (Blue) versus quick charging (Green)
NOTE: I was given a discounted product in return for an honest review. All opinions and statements are my own
I grabbed the 2-port charger at 10 bucks a couple of weeks ago at Android Police.
I wonder why there aren't dual QC 2.0 ones out there.

probably grabs too much power and the design to make that might be too complicated without having some power fall off? Personally, my phone is the only QC device i'd worry about and the rest could take the slower charging. But that's my 2 cents.
I have this charger, too, along with a number of other CHOETECH products. Their quality is top notch with affordable pricing!
I have this charger in white so it sticks out surrounded by all the black leather in my car, but that makes it easy to spot and I keep the white charging cable in the quick charge slot so I know which to use when my phone is low. It doesn't seem to charge fast while the phone is in use, but it does charge quickly if you just leave your phone idle and let the charger work its magic.
Even you didn't have a quick charge device, it's handy to have a two port charger. I'm happy with that product.
