Using Nexus 7 charger to charge mobile phones?

Hi,
Nexus 7 charger ouputs 2A.
Is it safe and ok to use it to charge Galaxy Nexus, Nexus S, and HTC Desire?
I am thinking more in the long run, if it does not brake the phones.
Thanks

It should not hurt anything.My daughter charges her Droid 4 with my charger every day.

It'll charge it really slow since phone chargers are 1A. Everyone will have their opinion on this but my opinion is I wouldn't use a phone charger on the N7....it could over heat due to it charging slow. But I'm sure you'll hear others saying a slow charge is better so....

I was asking the other way around.
To use Nexus 7 to charge my phones. But the previous user just answered, thanks James.
When traveling, I want to carry just one charger for all my devices.

Yup, it's fine, because a standard charger is, or used to be, 500 mAh, at 5 volts.
Some chargers are more mAh, like 700, and some are even 1 A.
If a charger is 2A, and your phone only draws 500 mAh, that is perfectly fine, because it's only drawing a quarter of what the charger can produce. In this case, the charger probably won't even get warm.

Neither my Sensation nor my wife's Sensation XL has died yet from using the Nexus charger
What mvmacd says is correct - just because the charger can supply 2A, it is the device that decides how much current it draws from the charger.

I actually find the charger that came with my razr does the job fine and its rated at 850ma. Other lower power chargers i have are slow though.
I doubt a slow charge would lead to overheating or else connecting to a pc would cause this too.
I think for chargers its a case of trying them to see how well they work.

Science proves other than your opinion. A too-low or too high max voltage or amperage charger can and will lead to overheating and severe reduction on battery life and can destroy the adapter as well.

Care to explain why Google says you can charge your device with a 500 mAh charger [standard USB port]? ["with the screen off"]
Won't it severely reduce battery life and burn out the motherboard of the USB? Oh, really? Google just forgot about that part when they were writing the instruction manual?

Modern devices and chargers shouldn't have this problem because of built-in regulators. A smartphone won't try to draw more than it can handle and chargers won't try to supply more than they can handle (unless they're very cheap).

I have been N7 charger on phone with no problem so far. I wonder about the statement about the phone not drawing more than it needs though. I replaced the battery in my TB after 9 months due to low life and swelling. I'm pretty sure the swelling came from leaving the phone on a car charger all day, even after the battery was full. If my phone had the ability to stop taking the charge it didn't need, this wouldn't happen...

My opinion still stands....I don't trust using anything other than the charger that came with the device. 6th post down makes perfect sense to me.

Your battery was likely defective. My phone literally stays on the charger all day when I'm not out.

If the phones also charge at 2A then you should be fine. If the phones charge at lower amps (say 1A or 1.5A) then I wouldn't recommend using it everyday as it may reduce the battery efficiency. If it's an emergency go ahead and use it.

There's no harm in using a higher current charger with a lower current phone because the charger is not what's actually charging the battery, it's the phone, and the phone will limit the charging current. You can confirm this with a multimeter. The charger can't force the phone to draw more current than it was designed for. This would be different if you were charging the battery directly with a dedicated charger because then the charger itself is directly controlling the charging current.

Would charging with 'stronger' charger affect battery longevity?

I'm just wondering if using a different charger would affect the Z1's battery life?
I've seen the description on the original charger, and it's charge rate is 1.5mAh and with the phone's 3mAh battery almost 2 hours for it to charge. Now, my sister and dad have tablets and their chargers' charge rates are 2mAh.
Again the question is, would using these charges affect the life of the Z1's battery? Again, I'm very concerned because as you know, Z1's cannot be replaced conventionally.
Thanks for your feedbacks. Appreciate it.

FYI
Hi guys! You're totaly wrong. If you are use high-ampers chargers for your phones, you can destroy your battery or, at least, significantly reduce the battery life. I have some bad experience with motorola radio stations wich we use in some airport service groups. When we buy hi-ampers chargers for it we was happy by time of chargeing, but after half of year useing it we just throw out all accums, because it began to hold charge about hour or two only
After consulting with with motorolla support we have found that its strongly not reccomended to use charger with higher amperage then recomended by manufacturer.
As a result:
Positive - we have quick charging time
Negative - disastrous decline in the lifetime of the battery

Thank you for your insight.
I have several questions though:
1) how long have you been using this 2amp charger? Was it continuous usage?
2) do you have any idea, or any exact figure on what "too high" means in numbers? That way we can all benefit if Sony phones could handle the extra "uhmp". And anyone who has a Z1 who can attest to this?

2amp isn't problem.
I'm using that charger (from my N7) and only thing I changed is cable - I'm using magnetic-microusb cable and that's great combo.
I'm charging Z1 from the day 1 (I bought Z1 in October 2013) and my battery is still perfect.
25-30hours with.5.5-6.5 h of screen time.

The rated output of a charger is the maximum output, however it will only output what the phone takes in - in other words, if the phone only takes 1.5A, the charger will only output 1.5A even if it's capable of 2.1A. Using a higher ampere charger would only work if, say, the phone can take in 1.5A but the charger only outputs 1A, then using a 1.5A charger would boost charging times

Yeah, that's what I also believe. But hey, then why do most gadgets heat up a little bit more when using a stronger charger? I'm not doubting the principles that you mentioned, but I need something tangible to look at: like an article from Sony for Z1 itself.
The other guy's experience and your comment here seems to be coinciding with each other, but You can never be too sure right?
But seriously, Thank you for your insight. I really appreciate it. That's what I like about the community here. Thanks man!

Gadgets heat up more when using a stronger charger because of my second premise - that the phone is capable of taking in a higher amperage than the charger that it came with. I think such a scenario is more likely since manufacturers would find a balance between charging times and heat, since too much heat would permanently damage the phone's charging circuitry as well as shortening battery life, so they provide a charger that outputs a lower maximum than what the phone can take in.
I do not know of any documentation Sony might have on this, but this is more or less physics in action. I did find a couple of readings here and here, and the main snippets are as follows:

Quick Charging OnePlus 2 possible with Nexus 6P charger?

Hey everyone, The OPT charger is around 10W (5A x 2V) while the Nexus 6P charger is 25W. Both devices have the same Snapdragon 810 chipset and they both use USB Type-C. Is it possible to get the Quick Charge functionality from the 6P (0 to 100% in around 90 minutes) to the OnePlus 2?
Thanks in advance

No, op2 doesn't have quickcharge built in. You might break your battery.

Energy don't work that way.
Think of your opt charge circuit as if it is a water hose, battery is a little container, charger is the big container.
It doesn't matter how big is the charger container the hose will take the same time to fill the small container.

Couldn't have said it better myself

Quick charge is a built in feature which is not included in op2. So it's not possible to charge it that way.

I believe the snapdragon 810 supports quick charge, however, the OP2 designers chose not to implement it, probably due to the increase in cost associated with upgraded current handling for some parts, but that's a guess on my part.
There's usually no problem with using a larger capacity charger with your phone because they're almost always self regulating. However, it will probably not accelerate charging unless the device supports it.

No it doesn't support it.

My OP2 charges in 1hr50mins to full.. I am satisfied with it.

The nexus devices don't quick charge, they however charge quickly (called fast charging) with the new type C connection via a 15w 5v/3a charger. It's a non proprietary open standard and not a Qualcomm certified type of deal. The question is legit, you could be able to get a quicker charge with the nexus charger.

Yes I know that they don't use Qualcomm Quick Charge but some fast charging that's possible because of USB Type C. So that's why I asked if the OnePlus 2 could also use the ''Fast Charging'' capability from the 6P

Quick charge/fast charge whatever you want to call it won't work, opt circuit/controller is designed for 1A current, it won't demand any more than that.
You can have a custom kernel that tells the controller to not "shutdown" with more than 1A but is your risk and probably won't speed up the charging process by much.
Opt charger is 2A and should be enough to test a kennel tweak, again changing just the charger won't work.

How is OPT circuit designed for 1A?? then why would they make a 2A charger, that makes no sense.
Fast charging on nexus devices is a capability of usb-c, not snapdragon quickcharge.
So I think we need to reevaluate this..
Somebody needs to test with a 3A nexus charger and run ampere.
Sent from my ONE A2005 using Tapatalk

I might be wrong in something.
I used ampere to "measure" the current always tops at 1090mA but with screen on, which also drains juice from charger.
Any way you need a custom kernel like boeffla to change the mA to charge I remember it tops at 2200mA
But a 3A charger like nexus will only supply what the device is demanding (2200 mA)
Fast charging on nexus it's a feature of charger and charger circuit, remember to have a puppies a ***** (female dog) needs to mate with a dog not a cat. You might force different species they could mate but won't breed.
You need any race of dog to have puppies.
The same you need any brand of 5V/3A charger for a nexus and you will have fast charge.
Opt don't have fast charge won't harm to try but don't buy the charger just to test borrow someone's
Sent from my ONE A2005 using Tapatalk

Opt supports 5v 2amp charging on screen off.
Quick charge (Qualcomm quick charge®) is achieved raising voltage and not amperage (up to 20 volts, in qc3) and should be both hardware-supported and software-enabled since is the phone that asks the charger for a specific power level (volts-amps couple).
The real question is: is qc hardware supported on opt, and, if yes, could it be software enabled in some way in a custom kernel or so?

Can anybody confirm if faster charging is possible with a 2A non stock charger? How much time does it take to reach 100 percent?

Absolutely correct, the phone doesn't have FAST/QUICK charger technology...
However a higher ampere charger like 2A could still charge a phone faster, hence my query above
Are you sure it takes 90 minutes to fully charge with stock 1A charger as mathematically it's not possible
3000mAH/1000mA=3 hours
Or
3000mAH/1.5H=2000mA or 2A
Pehaps you are using a higher capacity charger? That would explain it...

The time of charging with 2A is the same using a original charger with 1A. The limit is inside at the circuit control of charge.

Yes, you have right.
We can put a 10 A capability charger at our device, but charge control circuit is doing his job and let device charging with 1 A max, even if is there 10 A disposable....
Maybe with some command in hidden menu or with some customized firmware is a way to override this limitation.
(At LG 4X HD is in hidden menu a command that enable fast charging).

Where exactly does one have to change what in the root directory?

Maybe fast charge working with another type of charger: Huawei 9V2A Quick Charge Travel Charger
Instead of 5V1A(5W) or 5V2A(10W) with 9V2A(18W) charger, the charge circuit control will sense 9V instead of 5V and maybe switch to fast charge...

2 Amp charger are only needed if you are using a 2 or 3 meter USB wire.

The P9 Lite doesnt support any sort of fast charging. The ability of a phone to charge faster depends on it's hardware and the use of a fast charger. However, with a 2A charger, it slightly decreases charging time since the phone pulls approximately 1050mA. Be careful not to use a charger thats higher than 5V as it will fry your circuitry.

Where did you get this 1050mA spec, did u measure it yourself? This could be true as well, as fast charging is not observed by anyone until now except few online sources which state otherwise...
The part about damaging phone is inaccurate as QC 2.0 or 3.0 chargers are reverse compatible with old devices which support 5V only, the phone and charger never switch to 9V/12V/20V mode as the technology isn't there...

I did measure it myself with the aid of a friend. By the way, I was referring to a standard 9V/12V charger, not the QC charger.
According to my knowledge, the voltage is like a gateway to your phone, your phone pulls the current. Hence, if you use a standard charger with higher than 5V, you'll most definitely burn your circuitry. BUT....if you use a 5V charger with an abnormally high amperage, the phone will only pull the current it needs.

So just a quick question.
This means that for a phone to be able to pull 2A, is not just software control?
It means that the hardware has to support the ability?

I believe that is true. Although, most fast chargers (like the samsung one) only supply 1.67A at a higher voltage, normally 9V. This combination increases the output wattage of the charger....Like i said on my earlier post, the voltage is the gateway to the phone while the phone pulls the amperage.

Use QC3.0 everyday?

What do you guys think about it?
Is is "safe"?
What Chargers are you guys using?
thanks in advance!

I've read that G6 does not support QC3.0 for now but it's about to thanks to the incoming update.
But anyway, of course, why not!
I did so with my Xperia Z3 Compact which supported QC2.0 but it's pretty much the same case for our G6's. I never had any problems with the battery in my Z3C.
I'm also planning to buy QC3.0 charger, which one are you gonna use?

Well, i'm using the default charger, which is supposedly qc 2, but qc 3 shouldn't damage your battery in any way. It charges very quickly to around 85% and then slows down to preserve battery life.

first time i hear that
it says here:

and here:

also in several yt video tests that it clearly can do QC3.
i use that charger:

yep the included one can QC2 (asked LG support about it)
and ive read the same thing about qc3... that it is supposably battery "friendlier", thats why i was wondering what other lgg6 users do

I've confirmed that the charger that came with my G6 is QC3.0 (model MCS-H06UR, UK 3-pin). Using a USB power meter, the voltage will increase from 5V to 9V in small steps. If I use a QC 2.0 charger (stock charger from Note4/S7edge), it will jump from 5V to 9V immediately.

Now, this is interesting and good to know. But QC 3.0 has two components to it. One is the variable voltage, but the second is actually using voltages up to 22V. So it would seem that this is QC 2.5

Well, it just means that it can support up to 22V but not that all charger must support 22V to be QC 3.0 compatible. If you look around most QC 3.0 chargers only support up to 12V.
