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.

VOOC Rapid Charger confirmed working!!!

I plugged my OPO into my Find 7a VOOC charger at 1:04AM and I was at 8%, at 1:24 I was up to 29% now at 1:32 I'm at 36% so it is charging at 1% a minute And just so you guys know the quick charge will charge quick until the phone gets to a certain temp and then charges at normal rate. I guess this is to prevent heat damage

Heeey im so glad to know that!, but I worry about being damaging the battery by charging it that way, do you think it's possible??

I wonder then, if, in theory, cooling the device with some sort of water-proof ice-pack might mean you could quick-charge it all the way.
So the VOOC charger has a standard MicroUSB port? I wonder if maybe you can grab an app or a widget to tell us what its actual power output is? I use a 2A charger with my N5 and it charges pretty damn fast. Not 75% in 30 minutes as the VOOC charger claims to charge, but pretty quick nonetheless.

Actually it's 4.5A, but based on OP info (1%/min charge rate) I think Opo is limited to something about 2A/hour. Probably a 2A charger will charge at the same rate as Find 7 charger (4.5A).
My S4 can fast charge up to 1.9A/hour. So in an hour and half I have full battery.

It's not standard.
As stated by another poster, 2 extra pins (probably to deal with current limits) and also uses two pins (probably D+ and D-) to communicate between charger and phone. (This is very different from normal chargers, which just short D+ and D- together)
That said... IIRC the VOOC charging is supposed to be faster than what graffixnyc indicated. It may be only going at 2A in the OPO. I need to look through the kernel dmesg of my f7a to see if there are any "telltale" signs of VOOC being used in a dmesg.

You could install something like Battery Monitor Widget and see how many amps it's pulling.

It's confirmed to be working, but I doubt it's working with Opo the way it works with Find 7a.
I bet your Note 3 charger charges OPO at the same rate/time that Find 7a charger does.

There is always Qualcomm quick charge (2.0) which is supported by Snapdragon 801.

The Find 7a charger utilizes 7 pins vs the 5 pin standard for the micro USB.
This was found to exist in both the Find 7a and OPO (Reviewed Samples).
Though Carl stated on reddit that the production model will not have the special "7 pins", the sampled OPO devices did and was shown in a teardown.
So for one, the Note 3 charger is distinctly different than the Find 7a charger.
And two, though the sample OPO devices may have 7 pins, the production models may not.
Just hoping that the production models have 7 pins to utilize the rapid charge feature.

The USB ports on both devices look exactly the same.. there is a post on the OPO forums where a guy confirms (from a teardown) the OPO has the extra pins. However, I do notice obviously that it's not charging at the rate it charges the 7a but it's charging quicker with the VOOC charger than it charges my m8. @Entropy512 is it possible that there is also something in the software that fully enables VOOC charging?

You're right, I just saw some pictures of teardown and it has 7 pins indeed. But based on OP charging rate (1%/min), I concluded it isn't working like VOOC, which charges 75% in 30 mins (2.50%/min).
Oppo Find 7/a manual says that the charger can be used in other devices and it will be limited to 2A unless it has a VOOC chip if I remember correctly. So, this is why I think your Note 3 charger (2A) is equal to Oppo 7/a charger (4.5A with VOOC support and 2A for others) when used in Opo.
Besides, Oneplus didn't make any advertising expliciting VOOC support to Opo. I think it's a very rare feature in mobile world to be hidden.

I think Opo has fast charging on by default. M8 might charges at about 1500mah while Opo charges at 1900mah (I'm just supposing).
Try to enable fast charge to your m8. I believe it will charge as fast as your Opo.

There are some software changes, and in fact Oppo tweaked some of those settings on the F7a: https://github.com/oppo-source/Find...728e48ea4f50baaf1fd9e51cc7ae59d362788e#diff-5
hey... wait a second...
Those changes aren't for the F7a at all! The OnePlus Edition is the one with a PIC1508, and in the file with the compiled firmware - that's the Find7 OnePlus Edition section of the file!
It looks like in the original PIC firmware, the current setting was reduced for the Find7OP and they increased it for the OP with that patch - which might not be in the current CM11s build.
I'd do:
A/B comparison of the VOOC charger with a standard 2A MicroUSB charger
I might be able to get you a mostly-working Omni build later this week since the devices are so similar to play with, that will include the above Oppo tweak to the Find7OP

How about the modem hardware(baseband), can we flash find7a on find7po and the reverse?

Nexus 5X has Qualcomm SMB1358 Quick Charge 2.0 IC on logic board?

Hello,
I read in an article somewhere that the Nexus 5X has Qualcomm Quick Charge capabilities on the hardware side, but not on the software side. It also stated that this possible could be activated in the future. For the life of me I can not find the article now, but I did hop over to the tear down page that iFixit did on the Nexus 5X. Sure enough, the 5X does have the Quick Charge 2.0 chip on the logic board.
https://www.ifixit.com/Teardown/Nexus+5X+Teardown/51318
I'm not sure what this means exactly. Isn't USB C pretty much as fast / faster than QC 2.0? Or, would QC 2.0 via USB C be even faster?

This phone will never see qc. Google is all about open standards which is why it has usbc and can charge at 3amps.
Sent from my Nexus 5X using Tapatalk

God can people just stop with quickcharge?
The device is charging at 15W at max allready, and thats just for a short while. The majority of time charging is spent under 10W (2A).
QC is not magic and wont make a difference for N5X. My M8 with QC and the same battery capacity charges nearly identicaly as to my N5X (same battery capacity), it just goes 9v for a shorter while but the total wattage never goes above 15w for QC charger.

I feel like the desire for qualcomm quick charge is so that people can use the wall plugs and car chargers they already own because the adapters that actually support the usb c standard are few and far between or really expensive from Google, it's not about which one is better or faster.
Sent from my Nexus 5X

That chip is a power management IC with QC features, does not mean LG/Google even hooked up the wires required to use it or put in the additional components that might be nessasary to make it work. I don't think Qualcomm publicly releases data sheets so we can't know but I doubt the hardware as a whole supports it.

In case anyone is interested. I have a Quick Charge 2.0 certified car charger and it works with my 5X. It enables "Charging rapidly". Same thing with my Note 4 rapid charger. Both work fine.

Hove you looked at the actual charging rate at all? Just because "charging rapidly" does not mean it is truly charging as fast as it should.

I'm gonna answer this even though I don't appreciate your tone. So I'm doing it for the benefit of others. Yes it does charge at a fast rate with all three chargers (stock, Samsung Fast Charger, and QC 2.0 charger). About 1-3% per min and it slows down, as it should, when above 80%.
And "Charging rapidly" wouldn't get triggered if the power management charging circuitry didn't detect that the charger had the proper dynamic output voltages/currents, with the power output being P(t)=V(t)*I(t). Your "rapid charger" will have two pairs of output ratings for current and voltage (some have 3).

I'm not trying to be mean and I did not intend to have a negative tone so I'm sorry for that, I just wanted to see the actual numbers when using that charger you mentioned and see how they compare to the OEM charger because from what I have read charging rapidly is faster than normal but has a very wide range that can trigger at much lower charging speeds than the OEM charger.
Sent from my Nexus 5X

All of my testing on "charging rapidly" indicates that the phone is charging at 2.1A, not QC 2.0.
I suspect most QC 2.0 chargers offer 2.1A charging for when an iPad is connected, to prevent the user from returning the charger because it didn't charge their iPad. Google probably exploited that by simply telling the Nexus 5X to accept the iPad 2.1A handshake, which doesn't require QC 2.0 to be enabled.
It is possible QC 2.0 is just disabled in the baseband, but considering the backlash that Google got... I suspect they would have at least committed to enabling it, if that were an option.

That makes sense thank you

Fast charging with 2A charger

Hi
I am planning to buy this phone.
Can anybody confirm if faster charging is possible with a 2A non stock charger? How much time does it take to reach 100 percent?

The phone doesn't have fast charge
For me, it takes 1h 30m to charge from 0% to 100%

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...
Sent from my iPhone using Tapatalk

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).

I doubt we will be able to find any such software hack to allow fast charging.
There just isn't enough development going on for this phone for anyone to discover and share such information
https://www.androidpit.com/huawei-p9-lite-review
Above review was found by another user on this forum where it's mentioned that phone supports 10W (5V×2A)
So this is what I am hoping is correct and is verified by someone who owns the phone already

That would be really very nice, I would be really happy ).

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.

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.

Great that you actually measured it, I am assuming using an external device...
That would confirm it without doubt that online reports are incorrect and phone can't charge above appx 1A

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.

3rd party 45W charger - Baseus 65W GaN Mini Quick Charge US

Just got this on our country's local online shopping site (shopee) for about $27 (discounted and with free c-c cable). It's actually 65W and has two USB Type-C ports and one USB-A port. The first USB-C port supports up to 65W and I mainly use it for my laptop. However, I just discovered that it actually charges my Note10+ on 45W. The second USB-C port supports up to 30W and it charges the phone at 25W. Lastly, the USB-A also supports up to 30W but it only charges the phone at 18W.
Many have asked how I knew the power output on each ports when used on the Note10+, well a few months back, Samsung added the feature on one of their updates to display different labels when charging.
On 45W charging, the phone displays Super Fast Charging 2.0;
on 25W charging, the phone displays Super Fast Charging;
on 15-18W charging, the phone displays Fast Charging;
and on 10W charging, the phone displays Cable Charging.
So there you have it, if you're looking for 3rd party 45W chargers, I suggest you check this one out as well.
I also am not sure if xda allows me to link where I got this but I'll just do it anyway. To the mods, please remove the link if necessary.

Hi, how do you know what wattage you are getting with each cable?

im using baseus GaN 65W + type C to type C 100W from baseus and the 45w work properly

Nice find! It's available on Amazon in the US for roughly the same price as your link.

The later firmware of the note 10+ has different indicators when charging. On 15-18W charging the phone will display "Fast Charging", on 25W it will display "Super Fast Charging", lastly on 45W charging the phone will display "Super Fast Charging 2.0"

Explained perfectly. I was very surprised when I saw "super fast 2.0" on my note 10+

I bought one of these chargers:
https://www.giztop.com/baseus-120w-2c1a-gan-charger.html
Due to it's 87-watt output of the Type C port, I use it to charge the Note 10 Plus in full-speed, as well as to charge my laptop, which can be charged through the Type C port.
Even if I use both Type C ports at the same time, the quality and speed of charging does not decrease either in mobile phone or laptop, which is one of the strengths of this charger.
It is compact and has a very high quality.

I have bought several Baseus products, even 2 protective cases, without exception, all have been of a very good quality, and, reasonably priced

15W charger charges in 80min
25W charges in 65min
45W charges in 56min

Are there any drawbacks with those new GaN chargers? I mean, if they aren't becoming the norm, there may be any. Are they less durable? Maybe they produce more toxic waste?

Original firmware, still running Pie, will indicate "fast charging" with the 25 w brick.
Really that's all you need or want. Stock ones with cable go for $20 stateside. My original one is still charging away even after heavy use.
One other plus for the stock charger is it will charge even at 60 VAC. I inadvertently tested that when we lost one leg of electric power overnight. Didn't phase the brick one bit... and it continued charging.
Update, got a new N10+ running on Q. With the same 25w brick, Q shows it to be "super charging". Sounds faster

Doesn't faster charging (ie. faster than rated for the phone) make the battery deteriorate faster?

Yes. Any additional stress does.
Do you think about how rapidly the battery discharges when in use? Same deal.
When watching vids which draw about 12% SOT I give it a break every 20-30 minutes.
The whole phone interior is warm much of the time too, more stress.
Just the nature of having a finite lifespan. On a heavily used device you'll get 1-2 years lifespan.
It's no big deal, simply replace it when it's capacity drops below roughly 80% of it's original capacity to avoid a battery failure which can heavily damage, even destroy the device.
Replacing the battery is just part of using and maintaining the phone.
Even the N10+'s battery replacement which isn't rated as easy really is not that difficult once you learn the tricks. Just replace with a battery made in Nam, not China and use a new OEM seal on the rear cover.
The "permanent battery" stuff is just hype for most phones. There are a few exceptions.

So you charge your N10+ daily with a faster charger? And always to full 100%?
Well, if mine would last perhaps another 2 years, even doing this, I'd already be happy

Mostly always use fast charging. Not real concerned about replacing the battery but I do limit the level of discharge/charge.
Very rarely to 100% or below 30%
Li's like frequent midrange power cycling.
Typically 40-50 to 70-85% two or three times a day.
Overnight I try to start it at 50-70%
Don't start a charge if below 72F.
Never attempt to charge at 40F or less.
Optimum start temperature is 82-90F
Cool if it goes beyond 100F when charging.
Short midrange charge cycles create less heat and stress.
