Charge (even slowly) with 2.1 amps? - Nexus 6P Q&A, Help & Troubleshooting

I have a ton of 2.1 amp chargers. I have ordered the correct type C cables. I assume I can charge with 2.1 amps, but it will just be slower, right? I will eventually get dual port 3 amp car chargers and 4 port 3 amp home chargers.

Google supplies 3 amp-5 volt for 15 watts.
So - do the math - less than 15, slower

Yes, it will just charge at an average rate rather than support quick. All USB chargers provide 5V regardless of current, do they will provide must over 10W

Is there a way to see how many amps drawn with different AC chargers?

Edit: Crap meant to put in Q&A section. Could a mod please move?
I've found a few apps that are supposed to show the amps but everything seems to either always show 1amp or can't read anything and shows 0 amps. I have a kill-a-watt ez P3 but it's showing 0.16 amps being drawn with the three 2 amp rated AC chargers I have, so that doesn't seem to be of use.
Does anyone have any root specific ways to find this more accurately or any suggestions not app specific to figure this out?

This works!
Interesting results also.
I'm getting 1.9a with the OEM charger and cable but adding a desktop charging cradle to that will make it so to 460ma
Cables do matter. Non-shielded cannot hit the full 1.9a that a proper shielded cable can.
Not all 2a rated AC chargers seem capable of charging at 1.9a either.

It might be Samsung who limiting the charging of other cables or AC chargers :silly:

Samsung uses a voltage divider and signals the presence of their own charger by sending 1.2-1.3 V across the D+ / D- pins, this is similar to what Apple does with 2.0 or 2.8 V across the pins for various USB chargers they've shipped over the years. This signaling is essentially Samsung's proprietary tablet charging signaling which they've employed on the Galaxy Note 2 and now SGS4, in fact the two use the same exact charger, so it's worth tossing out your old ones and getting the appropriate one to take advantage of the faster charging

My iPad and some $15 brand called "Tech & Go" are both rated at 2.1a and according to Galaxy Charging Current they're charging at the same full 1.9a when using a proper shield cable.
Now my biggest challenge is finding a car charger that can do 1.9a as that's my biggest issue currently. When Google Music All Access streaming and GPS going with the screen on the chargers I've tried so far cannot even keep up with the power drain or just barley keep up. I need the full 1.9a in the car if I ever want to do those functions AND charge my battery up.
Anyone know of a car charger that'll do the 1.9a on the S4?

Verizon has a dual outlet car charger that says it's 2 amps. The questions I cannot answer about it are:
- Does it give 2A through one USB port, or is it limited to 1A + 1A.
- Will the S4 recognize it and allow itself to draw 2A, or will it treat it like other "unrecognized" chargers and limit draw to 500mA.

[Q] Recharge time > 8 hours?

Hey all,
I've been using my N10 for a week now and am wondering why and if it's normal for the tablet to require 8+ hours to recharge?
I'm plugging it into the wall using a generic USB cable and non-Samsung power block. Should that matter at all?
Signed 'confused...'
Yes, the charger matters. The stock wall charger is at 2Amps, while a normal USB connection is at 0.5Amps, for example. All devices will charge more slowly on lower amperages, but since the battery of the Nexus 10 is so huge (9000mAh - about double your average laptop), charging it from 0 to 100 will be dreadfully slow, if you're not using a proper charger.
1. Are there other wall chargers with higher Amp output that are safe to use w/ the N10?
2. Is there any long term damage to the battery using a higher or lower Amp charger?
Another issue is if the charger is made for an Apple product it doesn't short the data pins so the Nexus doesn't see it as a high amperage power supply and only pulls .5 amps.
Use the OEM Samsung charger or get one of these:

Higher than 2.1 amps? Not commercially that I'm aware of, though you could always jerry rig some contraption to deliver more.
The problem is, however, that the device will not draw the extra power. A device will draw the power it can use, and no more. I haven't tested what the draw is on my Nexus 10, but on my Note 2, it never draws more than 1.8 amps (although that reading may be a little inflated and it really only draws 1.5 amps). I suspect it's more or less the same with the N10 and the stock USB cable and Samsung 2.0 amp charger. So if you went nuts and jerry rigged a 50 amp power supply to the device, it would still only draw 1.5 amps.
Note that the draw can be affected by the USB cable you use. I've seen some USB cables draw less than 500mA where the stock Samsung USB cable draws 1.8 amps.
Bottom line is that you're not going to find a wall charger above 2.1 amps as far as I know, and even if you did, it wouldn't charge the Nexus 10 any faster. The problem is what you identified in your original post -- using some plain vanilla 500mA (0.5 amp) micro USB charger that you've had lying around the house for the past several years and assuming that it should charge just as well as the stock Samsung charger. It won't, as you discovered -- the N10 will only draw about a third of what it's capable of drawing from such a charger.
Be careful buying 2.0/2.1 amp chargers from Amazon or wherever, particularly if they're identified as Samsung chargers. They're almost always counterfeit, and no better than the 500mA chargers I mentioned above.
You might also want to look into the POGO charger cable because it allows the Nexus 10 to draw virtually the full 2.0 amps from the charger rather than 1.5.

Moto Z Force's TurboPower™: QuickCharge or USB-PD?

Does the Moto Z Force follow Qualcomm's Quick Charge standard or the USB-PD standard? I ask this because the TurboPower™ 15 charger outputs multiple voltages like QC standard; but the TurboPower™ 30 that comes with the Moto Z Force outputs only at 5V at a reasonably high available amperage of 5.7A, which look more like the USB-PD standard.
Additionally: which (if any other than OEM) wall and vehicle chargers available will optimally rapid/quick/turbo charge the Moto Z Force?
Thanks.

I can tell you this. I have a QuickCharge 3.0 charger at home (USB charging hub) that will not engage TurboCharging on either my Moto Z or my Z Force. However my Nexus 6p charger engages TurboCharging on both phones. Odd... I am going to try a different USB-c cable tonight to see if it does anything on that 3.0 charging hub.

Looks like the Moto Z force does not follow QC 3.0 standards. The reason the Nexus 6p charger is working is because it outputs 5V and a 3A current which is Turbo charging as far as Moto is concerned. I think our phones follow the USB PD standard. Reason being is the turbo 30 charger outputs 5V at 5.7amps. that's a lot of current but the voltage stays at 5v. Usb pd can get up to 20v at 5amps for a max off 100w. Quick charging is different in that it ramps up the voltage to 9v or 12 v depending but usually keeps current at 2a and below. USB PD tends to keep voltage low but ramp up the current draw. Quick charge will usually not see more than 3a on most chargers. If it does see 3a our phone will more than likely register as turbo charging. If not we get the standard 5v 2a charging. Bottom line is QC maxes out at 18w I believe. Our phones charge at 28w if you multiply 5v by 5.7a u get 28.5watts. This currently beats QC 3.0 devices which are all mostly 15w chargers hence why the Moto Z has the fastest charging out now. To increase power you either have to up the voltage or the current in amps. Different standards but achieve a similar goal.
I've tried all my QC 2.0 and 3.0 charging devices. Nothing will charge it fast unless it's the TurboPower provided by Moto. That pisses me off so very much.
I dont think these devices (nor the new Nexus phones) use QC or USB-PD. I think they all use something called USB-c fast charging. I returned my QC 3.0 charger and have another one on the way that claims to be USB-c fast charging. Ill report when I have it in 2 days.
If you notice the chargers for the Nexus and Moto Z phones are different than most chargers. The Moto phones have a non removable USB cable and the Nexus has a USB-c connector on both ends.
What I think we are looking for, and what I have on order, is a charger that has a USB-c input on it. I have a charging block that claims to have USB-c fast charging on its USB-c input. The charger I just returned that had QC 3.0 on it also had a USB-c input, but fast charging was not enabled on it. The new one claims to be.
So long story short you need to use a cable with the small C connector on both ends and a charger that has a USB-c port with fast charging enabled on it.

I also tested a Anker QC 3.0 wall charger and in half hour it only charged about 20%. Not quick or turbo speeds...
Very bummed. I just bought a QC 3.0 battery, car charger, and wall charger and threw away the boxes. I guess I can give them to my wife who has a LG G5...
I hope that eventually there are batteries and car charges that will charge this phone quickly. QC 2.0 was a feature that I very much liked on my last Phone (Droid Turbo). Being able to charge at those speeds was very nice on the road or with a battery.
The only other things is I believe our phones are equipped with usb 3.1 standard. I believe this standard allows for up to 20v of power at a max of around 5a. But any charger that does 5v at at least 3a will pit our phone into turbo charging. I have a Verizon branded fast charger that does 5v/3a and it recognizes it as turbo charging and actually does very good. Not as fast as the stock charger but damn close. Motorola stated they follow the USB C standard for charging which is 5v 3a. So i still say it's a form of usb PD that Motorola is basing there technology off of because the amps our stock charger is putting out is 5.7 amps. The usb c standard stops at 3a without usb 3.1 which we have on our phones and usb pd to up the amps. I would love to see you report back with the findings on the new charger!!!
We'll all know soon. I will even tell you the amps it puts out vs the stock charger. I have a way to monitor.
To save y'all time. Look for chargers that output 5v at 3a. These will turbo charge your phone. Just like the Nexus 6p and Nexus 5x our phones do not follow Qualcomm quick charge standards. So those accessories will do nothing for you because QC doesn't put out past 2a. QC does 9v at 1.67a. multiply that and you get 15watts. Same thing as a charger with 5v and 3a. Multiply that and you also get 15w. Different ways of doing it but same end result. Verizon has a wall charger and a car charger that outputs at 5v 3a. It is also Qualcomm quick charge ready for other phones you may have. It also states on the side of the box that it is USB power delivery 2.0 compatible which I think is why it fast charges our phones. You're welcome
The charger I ordered states: "USB C Output: DC 5V/3A". This leads me to believe it will put the phone into "Turbo" charging mode, but it won't actually charge as fast as the stock charger which is 5.7a. Oh well, it's better than nothing I guess. I can still use the stock charger when needed.
---------- Post added at 02:54 PM ---------- Previous post was at 02:40 PM ----------
I literally cannot find any aftermarket charger that will put out more than 3.0 amps. I think thats as high as we can get right now and the Force charger is the only thing out there putting out above that.
Yea I don't think any aftermarket charger right now supports anything above 3a. Our stock charger has a thicker cable as well. Since QC chargers up the voltage and keep a low amp rating they can keep the cable smaller. Voltage doesn't necessarily need a thicker cable but current or the flow of amps does. For more than 3 amps the cable needs to be thicker for more current flowing. Our phones can handle 30 watts of power easily our stock charger outputs 28.5 watts. 15 watts is considered quick charging that's why our phone recognizes it as turbo charging. One plus has a charger that does 5v at 4a that's the closest I know of 20 watts. I would just like the stock charger to have a longer possibly removable cable. Our phones with 5v 3a are really charging the same as the other QC 2.0 and 3.0 devices it's all 15 watts
Back again, now with a bit more info. If the Moto Z Force truly does draw 5.7A @ 5V it follows neither QC-3 nor USB-PD standard. Both like to change voltages, but neither have 5V anywhere approaching 5.7A. Pg 471 of the latest USB standard shows that the max current delivered at 5V is to be 3A before being bumped up to 9V. QC3.0 adjusts voltages via 200mV steps (if anyone has a link to the official technical specifications of QC3.0 please share), but only outputs 18W max.
My next step is to fully drain the Moto Z Force, hook up the charger to a power meter, and measure how much power it truly draws until fully charged. I might have to make a measuring tool that independently measures the voltage and current of both VBus lines if further testing is needed.

Should be easier and give the same results. What I use.
---------- Post added at 06:24 PM ---------- Previous post was at 06:10 PM ----------
I've come to the conclusion that the USB hub I ordered is as good as it gets. It has 6 ports. 4 ports that vary the amps up to 2.4a, 1 QC 2.0 port, and 1 USB-c 5v/3a port.
I really hope Motorola / Verizon / Aftermarket companies are able to come up with a charger for this device. I love my Moto Z Force, but with the battery mods, I would like to have a charger for work capable of charging the mod as well. I don't know if I'd be able to survive with the 3ft one that came with it. I went out and bought all of the 3.0 accessories and threw out the boxes as well, thinking it would work. No USB A > USB C Chargers I've tried have worked. I'm anxious to hear if anyone has found one that works.
I reached out to Motorola Customer Service, the person had no idea what was going on. I have a Quick Charge 3.0 Aukey charger at my desk, Ampere says it's charging at 4.341v but no turbo power blurb. My buddy has the "Fast Charging" Verizon one, but it doesn't say it either. Hard to tell if it even has QC or not. They did however load the official moto charger (OEM) onto their webpage. I may just have to live with this one. :/
The one I have on order will certainly put the phone into turbo mode. I don't know how many amps it will do but it will be at least 3. As far as finding something above 3, well I couldn't. I ordered my own USB cable as well (C to C) and could have chosen any length. My charger is a hub with 6 ports and one is a QC 2.0 port. Couldn't find one with the fast USB-C port that also had 3.0.

So these chargers will all "turbo" charge our phones? I'm particularly interested in he car charger...I have an aukey QC 3.0 that I bought for this phone before realizing it wouldn't do the job lol...
But the usb-c port on the one you just posted will actually work right?...
At home I'm not too worried because I generally only charge my phone over night, so a slow charge or short cable isn't a terrible problem

Yes all those chargers should turbo charge the phone. Not as much as the stock charger, but still turbo. If you want a USB hub with multiple ports there are only like 2 options for those. There should be many options for single block home chargers and car chargers though. The hubs are the hard ones to get.

Does the USB certification matter for the cable? Is a USB 2.0 cable enough or do we need 3.0 or 3.1?

Some questions regarding DASH charger, cable, and other phones

I'm aware to take advantage of "DASH" charging (5V 4A), you need a DASH charger with the circuitry, and a DASH capable phone.
1. Can I theoretically use any USB C to USB A cable with my OP5 and DASH charger, or will the phone limit the current? I understand cables may not support 4A of current, but I want to know will the charger and/or phone stop it from pulling so much current? What if I buy a high-quality cable off Monoprice? Or does the cable have to be "DASH Certified"?
2. If I were to plug in another phone into the DASH Charger and official cable, like say a Nexus 5X, how will the Nexus charge? The Nexus usually pulls 3A from a 5V charger. Can the Nexus still pull 3A from the DASH charger, or will it be limited to 1 or 2A?
3. If I were to plug the OP5 into another, non-DASH charger, what's the maximum voltage/amps it can pull? For example, the Nexus 5X charger is rated at 5V 3A. Would the OP5 be able to pull the 3A, or does it need some special circuitry? If so, what would it draw? 2A or less?
Last question: From what I understand if I use a laptop USB C charger, things should work okay- especially if the power brick shows it suppors 5V, 9V, and 12V. I assume the device will tell it to use the 5V line and draw whatever current it can. But what if I have a USB C charger that only says 12V on it? Or say 19V? Am I taking a gamble then? Let's assume this charger that is only rated at a high voltage is not a "shady" charger, and they followed the USB C spec properly. Should I be okay?
Thanks.
Any input or insight on these questions? I've read a lot about DASH charging, but looking for clarity on the above questions.
1. You can use any cable with your dash charger but your phone won't take advantage of the dash charging speeds and instead will charge at around 1.5 to 1.7 amps. So far I haven't seen a single cable no matter the brand working at dash charging speeds so the only cable I've seen working with dash charging are the official 1+ ones.
2. I don't have my Nexus 6p anymore to test this out but theoretically a 3 amp capable phone could draw the necessary amperage from the dash charger since the dash charger is capable of up to 4A. However, I'm pretty sure the phone will charge at the traditional 1 to 2 amps.
3. Amperage, as opposed to Voltage, is drawn by the devices themselves meaning a 5V 3A charger will always push 5 volts and can give up to 3 amps of power to a connected device. The amperage may be below or equal to the capacity of the charger, but never more. Modern batteries and phones have special circuitry embedded in them to protect them from over voltage or excess current and the OP5 is no different.
When connected to a charger, a phone will usually try to identify the charger it's being connected to, if if fails to recognize its capacity, the phone will reduce the amount of current to a safe amount that's below the charger's capacity. Seeing as there are many different chargers, like 2A, 2.4, 3A, 4A, phones usually fall back to a safe charging current that's within the lowest capacity of the most common chargers so even with a 3 amp charger, the OP5 will probably charge at between 1 and 2 amps even if the charger has a 3 amp capacity.
4. Computer USB ports are fine since they have a 5 Volt power bus and any extra current needed is passed through the BMC configuration line and/or the VBUS line only when requested by the connected device. As for using a higher voltage, since voltage is pushed to the device, is not a good idea to use a charger rated with a higher voltage that of the device being charged because you run the risk of overloading the circuits. Phone chargers used in cars usually operate at 12 Volts but they have DC/DC converters and resistors to reduce the voltage to the 5 volts required for phones and tablets. I'm not aware of AC chargers being able to operate with different voltage regulators.
1, No,you can only use official cables, but, I'v tested that oppo vooc cable+micro2typec adapter, can Also dash charge at 5v 4a,Turst me ,the charge chip is in USB C
In case nobody else does, I'll answer question 2 on Friday, when I get to the office. I'll be able to try it with several USB-C capable devices.
Hope I won't forget the dash charger home.
So, as promised...
Today I tried the following devices:
- Nexus 6P, LG 5, OnePlus 5
- Nexus 6 original charger (model SSW-268EU), OnePlus 5 original charger
- LG G5 original cable, OnePlus 5 original cable
I used Ampere to measure the values. All three phones were at around 50% charging state. Temperature of the phones was around 30 °C (+/- 2 °C). Measurement time was around 1 minute.
The results represent the maximum stable values (shown for at least 5-10 seconds). Where there was a variation, it meant that the reading varied slowly between those two. One value means that the reading stayed fixed at that value. Amperage readings are expressed in Amperes. No approximation made and any variation of less than 0.1A was not taken into consideration. (i.e. 1.4A = 1400 ~ 1500 mA).
The tests are not scientifically rigorous and should be taken as such. These results are purely informative.
On the horizontal are the charger&cable combinations. On the vertical,the phones.
Moto & G5
N6P 1.2A
G5 1A
1+5 1.3-1.5A
Moto & 1+5
N6P 1.2A
G5 0.8-1A
1+5 1.3-1.4A
1+5 & 1+5
N6P 1.2A
G5 1A
1+5 3.3-3.4 A
1+5 & G5
N6P 1.1-1.2A
G5 1A
1+5 1.3A
If I forgot any details, don't hesitate to ask.
Thanks for the information! Your tests are exactly what I was looking for.
Dash Charger Stop charging at 83%
Is there anyone facing dash charger stop to charging at 83%? But with another charger can continue charging until 100%....
On the topic, there is a QC to VOOC adapter on TaoPao that someone tested on the OnePlus subreddit and it apparently works. I wonder how exactly it works, though. Apparently it's capable of getting 3A from a standard USB-C and QC 3.0 wall wart.

Charging Oneplus with QC 4.0 or any other standard apart WARP

If I charge Oneplus 8 pro with lets say Car Charger with supported standards PD 3.0/QC 4.0/ QC 3.0/ AFC , is there a downside? Or just slow charging speed?
And, is there a downside if I need to charge my phone at work for example to take notebook USB Type C charger and plug in... (again apart of slow charge)

The rate of charge just be slower, otherwise no problems, no.
I just got the 8 pro yesterday, IN2025. From what I've read and i just tested your charging speed will be better w/ PD as the phone does not support QC anything and just treats as it regular charging.
I tested the charging at ~70%.
USB PD, 4.2V/1.8A - 2A
QC 3.0 4.2V/1..2A
Warp Charging, 4.2V/4.8A
Warp with regular cable, 4.2V/1.2A
Regular charging 4.2V/1.2A
Hope that helps
okay so my previous phone was a PD 3.0, I have a bunch of charger that are 3.0 which support up to 65W. What would it do with the OnePlus 8 Pro. will it be limited to 35W or will it go higher?
Always limited by the phone max specs.
so in that case I should still get the 30W from a PD 3.0 charger to the OnePlus 8 Pro?
Cause I don't want to spend $50 for a Warp Charge Car adapter specially if my PD 3.0 charger can provide the same amount of wattage

No, you will not get 30W from your PD charger, it will max out at 15W.
OnePlus only supports PD at 5V, likely because Dash charge only uses 5V. PD caps out at 3A for 5V, so 15W. PD achieves higher wattages by increasing the voltage rather than increasing the amperage like Dash Charge (hence why PD cables are generally thinner than Dash charge ones).

So in your case all chargers give less than required charging voltage?! AFAIK, only dash/vooc charges at battaries max voltage. others supply 5v. check your data
