Anker Quick Charger Test Results

I purchased the Anker quick charger (http://www.amazon.com/Anker-Charger-Qualcomm-Charge-Technology/dp/B00Q88Q16K) with a promo code a few pages back for $10 USD. Because I'm a nerdy electrical engineer, I recorded some data. Obviously the tools I'm using are very rudimentary so take all results with a grain of salt.

Test Setup: 2 minute charge test with screen off. Recorded maximum instantaneous mA from the Ampere app as well as the voltage.

Test cases:

Starting point is 78% Battery Life

Starting point is 37% Battery Life - Bonus, I also logged Kill-a-Watt power data. The Kill-a-watt is a very basic physical tool for measuring power consumption from a standard 120V outlet.

Results:

@78% with the stock LG charger, 4.3V and 1520mA

@78% with the Anker Quick Charger, 4.4V and 1960mA

@37% with the stock LG charger, 4V and 1660mA. Kill-A-Watt = 10W and 15VA

@37% with the Anker quick charger, 4.1V and 1970mA. Kill-A-Watt = 10W and 18VA

Thoughts: I was surprised that the Ampere app read ~4V with both chargers. That being said, the Anker LED indicator lit up green for 9V/12V mode. I suspect this voltage gets stepped back down within the phone to 4V and the measurement circuit is reading after it's been stepped down to 4V. The current does seem to be consistently around 20% higher with the quick charger. I was also surprised that the Kill-A-Watt reads exactly 10W with both chargers. However, the apparent AC power was elevated by 20% so that accounts for the extra current. Presumably there are more power electronics in series with the quick charging circuit which is causing some increased current draw that isn't in phase with the voltage. (Feel free to glaze over that last bit if you aren't an EE.)

Bottom line: this charger appears to be 20% faster than the stock charger. I thought it might be a more significant improvement than that, especially at a lower charge level like 37%. Oh well, every bit of speed helps I guess.

Awesome news, especially considering I bought a few of the Anker chargers :)

Thanks for the tests and clarification.
[G4 Accessories] Lock-N-Load:
I have a USB current tester coming and I intend to do another round of tests - I have run 4 QC 2.0 tests and average is about 1% per minute which is NOT official QC 2.0 quality numbers - to see what the actual reported readings are at low charge to full, middle charge to full, high charge to full on both my QC 2.0 and stock chargers. I then intend to do it on my QC 2.0 car charger. I think the USB current tester can really put some numbers as to what current is actually flowing. But no matter what, I do not think official QC 2.0 is on and I think the QC 2.0 chargers we all have are putting out more juice than stock - which is nice of course - but

not

QC 2.0 level speed.
[G4 Accessories] fachadick:
I posted the below in the troubleshooting section, but it's relevant here too.

Not all Quick Charge 2.0 chargers are alike - one of them rendered my phone unusable while charging;

I've been getting increasingly pissed off today because even though I haven't run into any issues with it yet, today I kept running into big problems with lag. It wouldn't recognize that I was tapping the screen and it was missing half the taps - so half the time it wouldn't unlock, or open apps, and typing was a nightmare. My phone became virtually unusable. Even thought it's been fine for the past few days, I thought I was running into the lag that everyone was talking about.

After hours of this, I realized that it was only happenning while plugged into the Keedox Quick Charge charger that arrived this morning.

Once I unplugged from that charger, or used a different one, all was fine again. I don't know if I just got a defective one or something, but I'll be returning that one, and getting anker or aukey instead.
[G4 Accessories] Lock-N-Load:
In the past, years ago, I 100% had issues exactly like this with a non stock cheap charger. Erratic behavior. Stopped using charger, no more issues. Bad voltage was freaking out the device. I forgot about it until reading this.
[G4 Accessories] woozzy101:
My old Motorola phones used to love freaking out when using some 3rd party chargers. Trying to type anything was nearly impossible because whenever you touched a location on the screen, it would start randomly clicking somewhere else repeatedly.
[G4 Accessories] bayniner:
Can anyone with the anker quick charge charger confirm if it will charge the g4 when it is completely dead, my anker would not charge my g4 if it was dead but chargers just fine when g4 is on, anker sent me a replacement and it does the same thing

Just a heads up for those of you that live near a Best Buy. They now sell quick charge 2.0 home and car adapters. Sometimes they go on sale and are around the same price as the ones on Amazon. I got the AC charger, and can confirm that it works very well with the G4.

I dont think this works.. I just got the ivolver unit linked in the OP and i get NO notification of quick charging and it is charging at the regular rate (approx 1% a minute).
[G4 Accessories] docfong:
The Anker charger is noticeably faster and worth $10

The iVolver is going back to Amazon. Not worth twice the price for a longer cable imo
[G4 Accessories] bozemajo:
Just ordered the Anker from Amazon. Thanks for the tips, guys! I'll report back if I have a great/terrible experience with it. Anything that bumps up my charge time will be an improvement, though.
[G4 Accessories] bayniner:
Hey does your anker charger charge your g4 if its completely dead, mine does not, anker sent me a replacement and its the same thing, charges great as long as phone is on. Wondering if thats just the way their charger is or is it my phone. Thanks
[G4 Accessories] BDestroyer8418:
My Anker charged when it was discharged. It turned the phone after awhile too while it was charging.
[G4 Accessories] Rolander:
Do you know if iVoler makes a quick charge wall charger too? I meet with lots of clients at starbucks etc, and a wall charger would be nice to have-- if i'm there early, I can charge up real quick and then throw the charger in my briefcase before the client meets me.

Hi.

I ordered AUKEY qualcomm certified 2.0 quick charger from Aliexpress @ 16USD.

My zenfone 2 charger used to charge my zenfone at 2% per min, really fast. But i returned the phone. I feel stock LGG4 charger is also fast, though not as fast as 2% per min.

What will happen if i charge G4 with CAPDASE car charger having output of 2.4A at 5V? Will it damage G4 or any other cellphone?

[G4 Accessories] Jammin72:
Bought the Aukey, while it charges quickly it's nothing like what's supposed to be happening with QC 2.0.

{edit}

I'll run a more detailed test. I think I'm getting confused by the 75% faster when really it's the empty to 65-70% in 30 minutes that I should be testing.
[G4 Accessories] tourbound129:
The QC 2.0 spec is actually 0-60% in 30 minutes. So 2%/min. The G4 will only do about 1.2%/min.
[G4 Accessories] smartedpanda:
Any particular way to tell if it's working besides running a timer to see if 60% in roughly 30 mins? I might return my charger. I can't tell a major difference besides slightly faster than my stock charger.
[G4 Accessories] lawrence750:
There are products such as http://www.amazon.co.uk/dp/B00Q2HWLYS/ref=pd_lpo_sbs_dp_ss_1?pf_rd_p=569136327&pf_rd_s=lpo-top-stripe&pf_rd_t=201&pf_rd_i=B00LZ07BG0&pf_rd_m=A3P5ROKL5A1OLE&pf_rd_r=0NP1ZRJXV1SZB6YN9DXA

There are apps that are supposed to do the same thing, but they seem to work on per device basis, and even then aren't the most accurate way of measuring the current.

You can also purchase a standard mains energy monitor, plug your phone charger in via that, and then it'll be able to give you a wattage reading, and using that you can work out how many amps are being drawn.

I haven't used one of the USB monitors, they look good and I'm tempted to buy one at some point. IMO, that (the linked product, or a similar one) would be the best device for this job.
[G4 Accessories] joshiks7:
Received Aukey 2.0 qualcomm certified charger from Ali express. Unfortunately sealing cover of USB cable had cut but wires inside are intact so applied tape , its working. Tried charging G4 from 20% to 90%. Initial half an hour charge gain was 40% and later half an hour charged phone with additional 30%. Does it qualify for 2.0 charging? Or charger is faulty?

Or else do we must have 0% charged (means totally discharged phone) so that charger works effectively at 2% per minute to achieve claim of 60% in 30 min.

I didnot find noticeable or significant difference in charging speed of Aukey and stock G4 charger.

Am i missing something?
[G4 Accessories] tiny70thomas:
I have 2 Aukey. Great product.
[G4 Accessories] joshiks7:
Aukey 2.0 charger juiced up G4 from 10 to 40% in 30 min . Means 1% per min.

Stock G4 charger charged G4 from 10 to 40% in 35 min. Means 0.8% per min.

Are Aukey claims of its fast 2.0 charger false (?). Reviews on AMAZON USA about Aukey are MIXED. Users reported many issues.

If G4 DUAL SIM H818N supports qualcomm fast charging technology, then which is relaible/trusted brand of 2.0 charger?

Has anybody on XDA has used and confirm 0 to 60% charging speed in half an hour? If yes, kindly let us know brand please.

Guys, I just bought an Aukey 5-port Qualcomm certified quick charger http://www.amazon.com/Qualcomm-Cert...1433929834&sr=8-5&keywords=Aukey+Quick+Charge.

It had very good reviews. Plus it is qualcomm certified. But the thing is when I connected with LG G4, nothing actually happened. No notifications of detecting quick charger nor any definitive improvement on charging as my device was already charging fast enough. But I really want to be sure about that my G4 supports quick charging & it's enabled as well I wanna know if my charger has any defect.

So can anyone gimme any suggestion what can I do? Plus is there any app which can tell me if my G4 is connected with a quick charger?? I am using Gsm Battery Monitor which just says AC adapter connected, neither I could really differentiate by Ampere app. I am attaching a screenshot from GSM, need someone to interpret it & give his valuable verdict.

So is this the best car charger?

[G4 Accessories] clockcycle:
battery low

you can install the ampere app it can give you a guess-timate..

I use a Zerolemon, it maxes at about 2000mA, slightly slower then when using it on my Nexus 6 by about 200-400mA. Got it to review, works great. http://www.amazon.com/dp/B00WM93M9S

It took about 1h 28m from 8-100%

2.1A chargers give it between 800-1400mA, so no real huge difference trying to get to 100% - QC chargers work better to give quick juice boost between 0-60% YMMV

EDIT: I'd suggest doing searches on slickdeals when youre looking to buy one, lots of discount codes for many of the popular chargers on Amazon http://slickdeals.net/newsearch.php?q=quick+charge+car+charger&searcharea=deals&searchin=first

Thanks man!
[G4 Accessories] adi_vastava:
I guess it's not the chargers, its the phone. I do not think G4 supports it properly. Not yet at least, may be a update will improve.
[G4 Accessories] BrunoSlivar:
Someone use tronsmart?

powered by LG G4
[G4 Accessories] clockcycle:
Sure the lg g4 supports qualcomm quick charge. If you check out the reviews on different phones youll notice all of them charge at different speeds. Lots of factors to take into consideration.

Like I mentioned the nexus 6 will show as turbo charging in ampere. Its original charger is 1.8A. Using a 2.1A qc 2.0 charger it draws approximately 2200~2400mA. Where the G4 was pulling 2000mA max.

Im of the opinion they chose this to save the battery's life. And prevent overheating/ battery buldge.

Using 1.5-2.1A rapid chargers my z3 n6 g4 all charge at similar rates. So thd chargers do make a difference slightly as well. My tylt 4.2A charges all my phones a bit slower than other rapid chargers.

Ive also tested a few car chargers rating1-2.1A they also fluctuate.

The g4 is the only one that seems ti drop to 500-600mA when the screen is on.
[G4 Accessories] adi_vastava:
I knew it supports or so the claim is.

I meant technically it does not seems to do that. The thing I read about quick charge is that it can use high voltage to supply wattage while drawing 2.0 A of current; it can go till 9V or 12 V if the phone supports.

I do not have another phone supporting QC right now but my G4 reamins around 4V-4.2V on QC with 2.0 Amp it turns out as 8 watts and with default charger its around 6.4-7.2 watts. (These values are total draw - current usage so actually draw will be slightly higher).

My QC charger supports 2.0 A @ 5V and at 9 V; or 1.5 A at 12V. G4 remains at 2.0 A @ 5V and never goes beyond that even thought the charger supports it. So it is just asking for 2.0 A current instead of 1.8 from the quick charger; but on same volts that made very little gain. And that is what we all see in our usage.

One of the review of my charges says this,

"I'm getting normal QC 2.0 charge rates with my Samsung Galaxy Note 4. With the screen off the charger is pushing 14.55 watts (9.04 volts *1.60 amps) and with the phone's screen on it's getting 7.38 watts (9.12 volts and .80 amps)."

Now this is just based on my understanding; feel free to correct it.

I do the results are same as reported with other devices.
[G4 Accessories] clockcycle:
It seems to be the same as aukey with different branding.

---------- Post added at 01:23 PM ---------- Previous post was at 01:19 PM ----------

Yes it seems that with any qc 2.0 charger it will draw 2A. Voltage doesn't matter.

It will draw much less with nonQC chargers. Again its not much slower than other devices. QC 2.0 states the device should be able to go 0-60% in 30mins.

My usb tester sleeve shows my zerolemon qc doing 9~volts at 880mA. The phone shows at 2000mA. Not exact nor scientific just gives you an idea.

Screen ON result pictured below;

Screen OFF result pictured below;

(Different usb detectors)
[G4 Accessories] adi_vastava:
That depends a lot on the battery size; with same amps and volt it can not charge big battery to 60% in 30 mins.

And voltage is what matters with QC chargers, IMHO. I have added a link from a review in my post, which describe it for note 4.

---------- Post added at 11:00 PM ---------- Previous post was at 10:57 PM ----------

I read your post incorrectly; my bad. Yeah for G4 it seems Volt does not matter and hence not so high performance with any QC charger.
[G4 Accessories] ironbesterer:
Oh there definitely is. My stock charger takes almost 3 hours to fully charge. My Quickcharger takes only an hour. I think it's probably that faulty cable. Don't ever use torn open cables.
[G4 Accessories] joshiks7:
Thx a lot. Which fast charger do you use?
[G4 Accessories] ironbesterer:
I had the same Aukey one but gave that one to my fiance and got the Anker one. They charge pretty much the same. But I like the slimness of the Anker one better.
[G4 Accessories] clockcycle:
Stock 1.8A LG Charger results (using a different usb detector);

60-100% will charge pretty much the same as a 1Amp charger.

Also the G4 slows down, disables quick charge when youre looking at the phone/ screen is on.

EDIT: just got home to find delivery of a multi color glowing led micro usb cable. Use it on my qc charger and it ran as if I was attached to a usb port on my PC. 460mA 5.19v!! Cables make a difference I'm guessing too.

Will Anker 2.0 fast charger make difference? Reviews are good.

You got 26% in 30mins. That's less than 1%/1m. You should have gotten closer to twice that atleast 40-50% in that time. Its advertized using a QC 2.0 compatible charger can do 0-60% in 30mins on the LG G4.

[G4 Accessories] tourbound129:
1.2% or so is as fast as the G4 will currently do no matter what QC charger is being used. It's a limitation of LG's implementation of QC 2.0. Whether LG provides a software update to ease the thermal restrictions is anyone's guess. This phone will not do 2%/min currently.

I get a lot more than 1.2, very close to 2% as long as the phone is under 50% charge and the screen if off.. As soon as the screen comes on, it disables quick charge.

Please refer to images on my previous posts. You will see the LG G4 (F500L is what I test on) does 2000mA, where the nexus 6 does 2200-2400mA and the sony xperia Z3 does 1600mA using the same charger(s). Every device charges at different rates, and there are different rates of charging done by different charges that claim to be quick/rapid/turbo or QC 2.0 compatible.

The Motorola Turbo Charge is only 5V 1.6A standard and it can do turbo 1; 9V at 1.6Aand turbo 2; 12v at 1.2A.

Which depends on the device/battery.

The ZeroLemon does 2.6A at 5V and 1.67A at 9V

[G4 Accessories] clockcycle:
That is the minimum to be considered QC 2.0 compliant. My Zerolemon on the nexus 6 is faster than that, the xperia Z3 is slower and the G4 is even to minimum spec.
