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.

How are those who've got their N10 finding the charging speed? Mine arrived yesterday and has been charging very slowly, as the reviews had said.
In six hours last night on charge whilst left on standby, it charged about 20%. Is everybody else finding a similar situation?
I'm looking forwards to the pogo-pin chargers/docks being released, which will hopefully charge a bit faster! If anybody knows how to hack something together to make use of the faster charging speed on the pogo connection then please do share! :good:
Of course, you have to look at the amperage and watt of your power supply. Even among the AC powered chargers, they vary greatly, and here you are talking about charging this behemoth with a measly powered USB.

If it takes 6 hours to charge 20% on a 2amp charger than that is seriously messed up.

Not messed up, just physics. There's an awful lot of resistance in a 9000MaH battery, and a standard microUSB (or even full-sized USB) connector can't handle the amperage that a faster charge would require. Which is why most big tablets had proprietary connectors up to this point.
But guess what? Google and Samsung knew this, it's why the N10 has one too, we just don't have the cable for it yet.
Pogo charger is coming, supposed to be at least twice as fast. Don't know why it was delayed, but most likely either a certification issue, or worry about Apple suing for it being too much like a Mag Safe connector.

Are the slow speeds people are getting from the wall charger our from a pc connection?
Are you saying a powered USB hub is charging it quicker than the mains charger supplied?
Thank you

I don't even charge phones via normal USB on PC anymore, let alone a tab. I've found the charging time on the N10 to be ok, provided the screen is off and also if I'm downloading something it seems to slow the charging down. Other than that it's not lightning fast, sure, but I'm ok with it. And so much the better when they release the pogo charger.
charged mine over night yesterday from 10% to full wall mains, but when the screen is one it doesn't seem to charge just maintains current charge which is a bit annoying

Try turning anything that uses power off (i.e)...turn the screen brightness the lowest it will go, turn the tablet on airplane mode. Turn the sounds off.
I find that helps my phone charge faster, maybe this will help with the tablet.
Are you talking about charging via USB on a PC, or via the PSU?
Through the PC will be very slow at a maximum of 500mA, but the PSU should be able to power it? My N7 and Galaxy Tab 10.1 had 2A chargers - what does the N10 come with?
I am regretring more and more buying this. I haven't received mine yet but the amount of pixels is kind of ridiculous. I would have been happy with 1920x1200 with that beasyly hardware. Saw a review that said their battery only lasted 4 hours because of the insane power the screen sucks away.
Also the fact that this pogo charger will probably cost $50+ and it is something that should have been standard either way.
Oh Asus infinity..why must your I/O be so god awful. You were almost the perfect tablet

Yeah charging is slow, though not as bad as 20% in 6 hours! I think mine was charging faster than that even when I was using it. I think trade off is worth it though with the microUSB connector.
The iPad 3/4 is no better... Takes forever to charge

Hi,
What is your charge time?
Mine is 2 to 2 and a half hours.
Which battery and/or charger are you using? After coming from the S2 I have noticed a large decrease in charging time with my S4, so this is very surprising to me.

...*facepalm*. You're not using original charger and you're complain that the one you use doens't works so well? Do you know that original charger is pulling 2000mA out, while your usb-port is pulling between 300mA and 500mA (depends if it front or back usb-port and the quality of usb port). Do the math, 2600mAh battery and 300mA / h. Full charge should take: 2600:300 = more than 8.5 hours.
With original charger S4 recharges from 0 to 100 in 1h 49minutes. If you take a solar charger it will charge even slower (like 48 hours for 0-100%).
Next time try to use your brain before complaining.

Your Samsung power brick has the cable physically attached to it? If not, you can just use a longer cable with the Samsung power supply.
The included power supply is 2 Amps, whoever is getting long charging times, make sure you use either the original Samsung power supply, or comparable in amperage supply.
Mine charges in 2 and a half hours.
Mine takes 2 to 2.5 h to charge from 0 to 100 percent. You should only use the new white charger, it's more powerful than the black one from s3, it's output is 2.0A ,old one is only 1.0A. Newer use other chargers as they may mess up your battery or phone.

I have to check the amps but based on google the Nokia Charger is at 1.3 Amps. I need to remind myself to switch the short Samsung to longer Nokia cables.
Is it safe to get a higher Amp charger, the one that the iPad uses to charge my S4? No drawback execpt for a faster charging time right?

Take it this way, grilling meat takes for example 45minutes to cook completely. You take it to some powerful furnace like 2000degrees for 5minutes then what do you expect from it to give you back? Well cooked meat or some burned meat outside and maybe raw inside?

put it this way... the s3 comes with a 700ma charger. it charges a bit slow. and has a 2100mah battery.
the s4 comes with a 2 amp charger. thats 2000ma. it doesnt charge slowly if you use this charger. i personally am going to pop it on this charger when i get home from work and then keep it on my 700ma charger overnight... no reason to waste that powerful output, it will simply waste electricity.
make sure:
1. you use the charger that came with it
2. you use a cable thats as long as (or shorter than) the stock charging cable. longer usb cables tend to charge the phone slower.
also keep in mind usb ports charge any phone slowly. the s4 will charge even slower on them because the battery is oversized compared to most.

I don't know what drug Apple put in their chargers, but i've always noticed my iPhone charging waaaay faster than my S2.
I even tried draining them both to 0%, and charging them with their original chargers. As soon as the iPhone was full of juice, the S2 was just about 50 or 60%
So i did some research about the safety of using the Apple charger, and it appeared to be all OK.
I'm going to end up buying a new battery anyways because i feel like mine has worn out, so i thought it was a good idea to plug the S2 in the fruitplug.
After i plugged the USB cable into the Apple charger, i immediately noticed the phone charging way faster. Waaay faster.
The phone does get a little warmer, but not too warm. I charged the phone from 8% to 100% in less than a hour!
I'm still experimenting the safety of this, by constantly keeping a look at the temperatures, and how hot the thing feels, and it appears to stay safe.
I recommend to remove your case and battery cover and keep an eye on your phone if you consider trying this, but for now i can say one thing:
If you have an iDevice in your house, charge your phone with the fruitplug
on the other side... what do you think about it? Would you try it?

According to the information on the charger, it outputs 1A. My samsung charger also outputs 1A, yet it charges faster with the iPhone charger.
I did some quick research and found that the iPhone charger would have a special sort of **** inside of it that charges the phone in a different way. Not sure if bull**** or actually true, but they did put some sort of magic or drug in that thing to make it hypercharge anything i charge in it
They couldn't have put anything inside, it all depends of voltage and amperage.
You can use charger with higher amperage than your device need though.
And, yea, you can use charger with more amps, but you cannot use charger with higher voltage than 5V.
iPad charger gives [email protected], but last time I tried it with a Samsung phone, it wouldn't charge.

The higher the amperage, the faster your phone will charge.
You can use charger with higher amperage than your device need, your phone would charge just fine, only faster. But it would cause heating your device, thus reducing the life of your battery.

So 650mah, and a 1650mah battery, that means 2 and a half hour for full cycle. And that also means something is happening to that apple juicer

This.
S2's hardware doesn't allow it to charge more than 650mAh from an external charger. So it doesn't matter if you're using 1Ah or 2Ah charger, it will be the same.
Now, that's for the international i9100, who knows if there's something different with other versions or if the phone has a faulty hardware. I've also noticed that my phone recharges much faster right after being quickly discharged. So it could also be that the metering is faulty and there was juice left in the battery.

I've also noticed that my phone recharges much faster right after being quickly discharged. So it could also be that the metering is faulty and there was juice left in the battery.

Im using M250S version, and it doesnt seem that there are any differences

A charging dock for the battery only, maybe. But be careful of those, they can make battery "fat" then eventually broke=

Then you overcharge them.

I dont have a proper charging dock though, i can only guess when it's finish, and that's dangerous. Im using an ipad mini charger now and it's fine, just can do the 1hour-to-full like op's

And that's awesome
Is it just me or do the batteries seem to run down pretty fast with Z2/Z1/SP when watching movies and browsing web via 3G internet. Also, gaming drains the battery faster than it charges. Using default charger.
Z2 has one of the best battery times between all android devices, so i think your expectations are a bit too high.

Yeah but even when plugged in, the battery level drops if I'm browsing using mobile Internet to combat the drain, I had to use a third party high wattage charger.
You are not the only one. If you are using it, battery drain very fast. Although it can manage one day. (for me)
I can easily get 2 days usage out of my z2 without charging.

Same here, 2 days is no problem

Make sure to use original usb cable to charge as well.

Drains faster than charging? I didn't test how long it lasts, but I expected it to charge when plugged in.

Usually I charge it over night. But I tried it with a car charger (3.1 Ah) (using navigation) and it drained faster then charging. It was not original sony car charger (which is 1,5 Ah). It is interesting...

Can you test with original? I did with mine and it drains faster. The only way is to use a higher wattage (about 2..well only one charger works-- BRAND NEW 3 PIN PLUG USB MAINS ADAPTER CHARGER for HTC, BLACKBERRY, SAMSUNG, MP3,TOMTOM, IPOD AND IPHONE - WHITE #11i UNIVERSAL 5V 1A CE ) charger.

Unfortunatelly I do not have original car charger. But I think I can test with original wall charger and play some games or run navigation. I tried 2A original Samsung tablet charger. It charged, but I don't test if it is really charging with 2 A or only 1 A. I will test it.

So, with 402 firmware I tried a HAMA car charger (2.1 Ah) with navigation and it charged. With original sony wall charger (1.5 Ah, firmware 312) 3G on and playing some games and it charged as well.

The battery charge is going up? So they fixed it? Cool.

Yes, it is going up. I will try later the other (3.1 Ah) car charger, maybe there will be some improvement as well.

Try playing some YouTube videos while on 3G?
I use my HP TouchPad charger normally when charging (2A). It tends to give slightly noticeable faster change, although not as fast as using that charger on my spare phone (Xperia T) as expected.
