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.

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.

Is it safe and ok to use it to charge Galaxy Nexus, Nexus S, and HTC Desire?

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.

Use the GNexus charger, usb probably doesn't put enough juice through..
The stock charger for the n7 is 2.0a, USB 2.0 has an output of 500ma max, it just isn't enough power to make a major difference.
even a gnex charger wouldn't be as good as the n7 charger, my gnex charger output is rated as 0.7a on the charger.
My S3 charger is rated at 1.0a

In Ireland we have 220v as well so it should be fine, the charger handles what is output to the device so it should be fine.
The device in every country has the same input, its the charger that is different.

See if you can get an official one from eBay or something, I don't wanna tell you to get a 2.0a charger just in case.

Self explanatory really. I realise any micro USB charger will fit, but I've read that of the voltage / amperage doesn't match, it can fry the phone. How true that is I don't know, but I don't want to risk it. I asked LG, and they directed me to their spares and accessories website. Initially it looked promising, but it turned out the website was terrible, was no info about anything.
I've had a look to find other 5V 1.2a (the specs of the charger that comes with the phone) micro USB chargers, but not had much luck. Any chance anyone could send me a link to a charger that matches the nexus charger? That would be very much appreciated.
Sent from my Nexus 4 using xda app-developers app
I read something that said if you use a charger with a higher amp, that won't cause any problems at all. Is that true? So I could use a 5V 2a charger with the nexus 4 (the original charger was 5v 1.2a)?
The reason I'm so concerned is that when I use my HTC Desire charger (5v 1a), the screen stops working properly. I used it all the time when I first got my phone and the battery in the phone died, and I had to get it replaced. I don't want that to happen again, so I don't want to use a charger with different amp output.

Yes, that's true. The phone will only draw the current that it needs. A 2A charger won't "push" the whole 2A to the phone, the phone will just "pull" the 0.8A or so that it needs.

...*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.

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.

Even that is unlikely because the phone regulates how many amps to draw. The current allowed is regulated based on multiple factors including the battery temperature and the charge present in the battery.

Well the second scenario was if said bits failed

Think of volts as pressure, and amps as volume of flow.
Think of a conductor as the empty space of a pipe, the insulation as the pipe wall.
Higher volts needs stronger pipe (conductor insulation). The limited insulation in most modern electronics will burst if to much pressure (volts) is applied, causing a short and a fried device.
Higher amps requires a larger pipe (conductor) and will most always be limited by the size of the pipe, or the amount of volume consumed downstream.
If a charger puts out 100 amps and only .75 can fit through the pipe under a giving pressure (5 volts), then only .75 amps will be able to come out of the charger, without damaging anything.
