Hi all.
What is the recommended voltage and amperage output for a car charger for my NS?
I got an aftermarket one here that is 5vdc/500mA, but my NS gets really hot while charging with this one.
Thanks

The NS will get hot while charging, especially if it's being used at the same time. It's normal.
You definitely want more than 500 mA though. The NS can easily draw more than 500 mA while in use. 1A car chargers are easy to find and will work much better.
5V is a requirement though. That's standard USB voltage. The voltage doesn't change from charger to charger.
1A. Great, thanks for the response.

sorry for English not perfect. I am translating with google.
I have a car charger that marks OUTPUT 5V --- 650mA (max)
if i use this charger with the nexus one I run the risk of ruining the battery?
Or can I use it safely?
I think you will be alright in terms of damage, but you may want to look at a 1a charger or like a 900ma charger so that when you are using the GPS and all of that it can continue to charge instead of not being able to keep up with the draw from the device(what I am thinking will happen with the power output from the charger you mentioned.
I can try and better explain if I was too confusing, hope this helps

Where have you guys been able to find an adequate charger for GPS and normal phone use? Ive had trouble with this.
manual, in specification, is written:
Charges at 480mA from USB, at 980mA from supplied charger
What does this mean?
So my 680mA working? or not?
It will charge. Just slowly. And if you are using gps or streaming audio it may not keep up.

try nokia dc-10 1200 mah - can't beat that. Little on the expensive side but is retractable and looks great

the "quickcharge" port on it is 1a, the regular is 500mA.

Hope it works better than the Belkin "Quick Charge" USB car charger my wife has for her iPhone, I don't get a quick charge on it on my Nexus One. Middle pins aren't shorted I presume.
This question has been asked before but no one can answer it odd.
Nexus 7 charger is two amps. Stock s3 charger is one amp.
Can I charge my s3 without damaging it using the other charger. People say it charges faster. Some people say it doesn't matter because the kernel will limit it.
Whats the real deal?

I am pretty sure it will use only what it needs. Atleast thats what i been taught at radioshack

There are a lot of variables as to what the maximum charge current will be. I've never seen it go over .8 amp. So if you use a 1 amp, or a 20 amp charger, it will be .8 amp. MAX. Usually less.
Use whatever you have handy that is 5 volts.
I actually use an old 5 volt .6 amp charger for overnight charging. A bit slow, but I don't care.
I have a home grown charger on my motorcycle that can go well over 1 amp, but the phone only has ever gone to about .8 amp. For a long time I had that charger set to 5.5 volts, and the current was up a bit closer to 1 amp. But the heat worried me and I bumped it back down to 5 volts.
Have been charging my s3 on the new iPad charger, and 2amp chargers bought from amazon without any issues.

I'm using a RCA dual usb charger one usb plug is 1 amp and the other is 2.1amp both charge fine but I don't notice the 2.1amp charging any faster. I so kinda point less to use in my eyes

You realize you're using a 10v charger on a 5v device right? That can toast your battery over time, a short time too depending on if you leave it plugged into it over night, etc..
I purchased the Mediabridge high output USB car charger from Amazon and shorted the 2 middle pins for AC charging. Prior to the mod it was charging at like 405mA, after the mod I'm at about 907mA. Does that sound about right? For some reason I thought it would be a little higher. Those of you that have done this mod, are you getting higher than 907mA?

According to the original hardware mod they were getting around 800 mA so you have 907 is actually better not to mention in all depends of the charger etc

Cool thanks for the info. Tested it out his morning and in a 30 minute commute to class the battery went from 44% to 80% so it seems to be working quite well.

The max I've seen on any charger is around 905mAh, so yeah, that sounds about right. I think there must be a current limiter internally, as I've used a 2mAh charger and it still only charges at 905-ish.

hello
My stock charger is us for galaxy s4 (samsung regular charger)
and then I found this (link above) with 2.1A
is it matter charging via 2.1A and not 2A? what is the different? it will charge faster/slower?
thanks
In Stock kernel there is current limit 1.9A. So everything above it, will be the same as 1.9A.
In reality, you will find that even 2.1A charger doesn't supply even 1.9A. Chinese charges definitely don't supply current thay claim. And beware of them - you may fry your device by such cheap charger.
Also, it heavily depends on USB cable as well. It has to be very short and very thick.
I have a Mediabridge car adapter that has a 2.1 amp charger on it. When I charge my S4 with it it barely charges faster than the 1 amp charger does. I think it charges at either 1.3 or 1.7 amps, sorry can't remember exactly.

How do you measure the exact amperage that it charges at?

I don't have the equipment to measure it exactly. So what I did was charge my phone from 50% for 40 minutes on my stock Samsung wall charger and then recorder the percentage it increased. I then took that number and assumed it was charging at 2 amps and used it as a baseline. Then I did the same test with my car adapter and recorded the results. The I figured out the percentage difference and came up with me estimates. I just don't have the data in front of me anymore but I remembered it being somewhere between 1.3 or 1.7.

The stock charger is fast at charging this phone. On my s3 it took forever . I would stick with stock

Chargers, power supplies, etc, don't "decide" the amps that go to a device - the device "draws" a certain amount. Just because a lamp is plugged into a 20amp circuit in your home doesn't mean 20 amps are going to be shoved through the bulb.
So if, as sorg says, the phone is only going to "ask" for 1.9a, you could plug it into a 5 amp charger and it would make no difference.

You already got your answer above.
No, your phone will NEVER charge faster than 1900 until a developer comes along and figures out how to hack the system to allow this. And it would be a potentiallly STUPID idea to charge faster than Samsung has deemed safe.
Go here to find out how to test your charging rate:

I have note2 right now which have to go. But I'll keep my office charger which is 2A.
Can I safely use it to charge n5?
Sent from SGH-i317m
Using chargers with a high power (A) is no problem, the phone will not "take" more than it needs.
Sorry for the poor english ^^
The issue is if charging IC can handle 2A current or not. I dying wanna fry it lol
I would think it should not be an issue while 2A ICs are widely used in our days, but "better be safe then sorry".

I charge mine with my xz charger 1.5a no problem
The charging block that comes with the Nexus 5 is 5.0 volt, 1.2 amp.

While AFAIK there's no 1.5A ICs, than its 99% safe to say they using 2A nominal IC.
Thanks guys

If using a different charger was a problem they would have made the connection something other than micro USB.

Not really. Charging current depends on IC installed, not the connector itself.

From what I understand, you could use a 10A charger and still be fine. The handset will not take any more than it needs. Basically, the charger doesn't push current, the phone pulls it.

Thats correct and nothing else. No way to destroy a phone with too much A because it just takes as much it needs. The 2A on an charger is just the maximum power output. It is physical impossible to PUSH the ampere in the device.
