Is there anything wrong with using my iPod charger to charge my nexus 7?
It says 5v 1A, and it's an aftermarket white cube iPhone/iPod charger.
I plugged it in for a few seconds and it showed the charge icon.
Some people say it's better to charge slowly, and others say you might burn up the charger, so what's the deal here?
Also, does Apple have some kind of funny voltage thing? I seem to recall something like there's +3v or something on the data pin? Will that mess up something with long term use?
And while we're at it, what about the standard USB wall chargers, 500 mAh? How about those?
Yes there will be world war 3 and you will be taken to court.

The N7 charger is 2A, not 1A. So do not use it.

what if it was 500 mAh?
even google says you can charge [with the screen off] at 500 mAh [standard phone charger, usb, laptop, etc]
so why would making that 1A ruin my device and the charger?

no it will just charge slower. i dont know where people are getting their info that a lower amp charger can ruin your nexus. if the amp is too low it just wont charge. So when i nexus is plugged into my desktop to transfer files and charging it can get damaged?
ive been using 3 different chargers on my nexus 7 and they all work but at different rate. the lowest one is a 700mah motorola car charger that can still charge the tablet running maps and tethered to my phone. It charges very slowly though.
sometimes i plug it into my 1amp samsung charger to charge it overnight and would charge the nexus is about 4-5 hours. Im not sure if this is true but i read that using a slower charger is better on the battery. just be careful using cheap chinese chargers, those can ruin your device if you get a bad unit.

so how can it ruin my device? I can see how the charger can get burnt out if the 7 tries to pull too many amps from it...
and my charger is a chinese charger..

I'm not say all Chinese chargers are bad but just be careful with it. If your charger or tablet is not getting too hot while charging and stops when the battery is full then it's probably fine.
Will charge really slowly but will not damage. Why not using the n7 charger?

won't hurt it, I use many diffrent charges depending on where I am @ the time, mostly I use a cheap china dock that charges @ 1amp, a bit slow but works fine.
your only issue may be the scorn your n7 feels as an apple product revitalizes it

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....

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.

Hi,
I wanted to know if N4 uses battery or only use AC Power.
While is connected to a charger when:
A) N4 status = "Charging, Nº %".
B) N4 status = "Charged".
Assume for this, chargers....like LG retail travel charger 5V 1.2A or a Samsung Car charger 5V 1.0A.
B.Regards.
I'm not sure if this answers your question but I found this true for any smartphone including the Nexus 4. If you are doing something such as GPS navigation in the car and you do not have a charger that outputs enough current your battery level may still go down. Yes, thats annoying. The solution is to use a charger capable of outputting enough ma. I also stick with the chargers included with each of my devices. Ive had too many problems with using third party chargers.
Just food for thought.

I think that always is battery powered. When you are charging, if power in > power consumition then the phone chargers.

Do you think 1A would be enough for "Google directions" usage (CAR GPS).?

Stock charger sucks (attach never unplugged charger)
Mmm i just played a race in ASPHALT 7 and my battery was raised from 91% to 94% on Stock LG Charger...
(Maybe ASPHALT doesn't use too much battery? its the heaviest game i have..).
So is it me or does the s4 charge really really slow ?
is this the same for everyone ?
any fixes ?

How long does your phone charge from low to full? Mine is around 2 and 1/2 hours maybe? Im using my Nokia 808s USB charger though. havent tried charging it with the included white charger, cable is too short for me.

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.
Well I tried charging from my computers use port at work today only rise 20% in 2 hours

...*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'm using note 2 charger and if I surf Web while charging, literally it is not charging at all.. battery is not going up or down.. Note 2 was not like this.. i could charge battery even if I play 3d game..

Nexus 4's (from Google):
The input voltage range between the wall outlet and this travel adapter is AC 100V– 240V, and the travel adapter’s output voltage is DC 5V, 1.2A.
And I have another charger that says 5V2A, is it too much or can I charge with it?
How can I know what is the voltage of the iPhone's charger?

It's 5V. Anything USB will be 5V. Don't worry about too much amperage. The phone's internal circuitry will limit/regulate how much juice actually reaches the battery. I use a 2A charger on my Nexus 4 all the time.

It might charge faster. I honestly don't know, nor do I know what the max amperage/speed the Nexus 4 charges with. Heck, I don't even know what the stock Nexus 4 charger was, since I got my N4 second-hand. Come to think of it, I should do some tests, just for future reference. I think I only have .7A, 1.8A, and 2A chargers though (the latter 2 being for tablets).
