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.

Hi
I'm having a problem with charging my HTC devices on my Honda Fireblade.
My motorcycle dealer added a cigaretlighter so I can charge the HTC while driving and using it as GPS.
The problem is that the Sensation (and even my Desire HD or HD2) won't charge although the indicator light on the charger is on. So I've tested the charger with other equiment and it works.
Does anyone knows what can be the problem? The battery of the Honda is 12V
thx for any advise!
What is the charger output?
It should have 5V and 1A or 2A. If voltage lower, it will not charge..

I use this charger also in the car and there it works.
I bought this charger when I was on a trip and it's original for nokia
He's right, your charger probably doesn't have enough output. I noticed that certain house chargers I already had were charging the phone extremely slow and others charged the phone quickly. That's when I noticed that the ones that charged the phone quickly were 5v and had at least 1A. The ones that were less were too low of an output to charge the phone properly. You're more than likely experiencing the same thing. I'm willing to bet if you check what the output is on the charger you're using you'll probably see it either isn't the right voltage or the amps are too low...or both.

All right, I'll check it first....it's in the car now
The nokia charger is
input 12 V
output 5V - 550mA
So you guys are right....it still doesn't explain to me why the charger works in car and not on motorcycle. Maybe because the battery output in car is higher A?
I'm not into electrical stuff :-(
So, if I order for example this one....it could work on my motorbike?

Bear in mind I'm just speculating with this but your car's cigarette lighter may be putting out more power than your motorcycle's (especially since it wasn't original). Also though it may have been charging in your car, that doesn't mean it was charging at the rate it should have been (it might have been barely charging). Sort of like what I was saying I had experienced when I used a lower output charger (the really slow charging).
Yeah that looks ok. I'd imagine that you be sufficient.
The charger I have is a Nokia DC-4. Bought from Nokia themselves as lots of shops sell copies. The copies don't seem to have the right electronics in them to power the more expensive (read: power hungry) phones. I have to have a converter on the end to go to micro-usb (also a Nokia part) but it means we can also use it for the wife's Nokia.
I'd make sure you went genuine part, or at least one that someone else says works.

It should be working. But better you try it first, borrow from a friend that have this charger and try it on your motobike. If still not working. My conclusion is that your motobike most probabily produce a low voltage or current than what it were suppose to.

I've received the charger. Did a test last night and test....failed. Still not charging.
So :
could it ba the usb cable itself?
can I measure the output current on my bike?
I'm with stupid on these matters, and my mecancic is on holiday
After using a wall adapter to micro USB port charger that only supplies 0.7 A instead of the 1 A the stock charger does, the lower adapter got very hot. Does the phone still try to draw one amp if its not connected to a PC through usb? Considering the standardization of micro-usb it would seem like G2x owners will try to use chargers at friends houses for other phones and it may not be the safest thing. Any input?
My factory LG charger only provides 0.7 amps.. but I use my hd2 charger that provides 1 amp cause the phone charges a little faster on it.. so I don't understand what your actually trying to say?

Phone can only draw as much power as the charger supplies, up to something like 1 amp. If the charger supplies less than that, then it only draws what the charger supplies. If the charger supplies more than 1 amp, then it will still only draw the 1 amp that it needs. The more important thing to ensure is that the voltage of that charger is the same as the stock charger.

It's strange we got different chargers. This one outputs 4.8V at 1.0A. It also squeals when the phone is in standby. If i wake it it stops humming. Model STA-U13WR2. I wonder if charge rate has to do with anything bad? When the charge says completed and it is plugged into a USB port, it will charge for another hour at times. Makes sense since a high charging rate will cause the battery voltage to spike and read as if the charge is complete when it's still got room.

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.

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".

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

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.
Gday All,
I realise that this topic has been mentioned in a few threads, but from what I could find, there is no definiteve fix.
Is there a way to disable this so that a non-genuine charger will work once the screen turns off, or if I was to root the device, is there then a way to do it.
Please dont flame me, I'm a total newb to android, and I dont mind admitting that.
Bit dissapointed that Samsung has sunk to this.
TIA!
Not sure what issues you are having but I have been using a few different chargers without issue. Which exact charging method are you trying to use (cable type, charger type, charger rated output voltage and amperage)?
Sent from my SM-P900 using Tapatalk
The problem isn't that the charger is 3rd party.
The problem is that the device requires a 5.1V 2A charger or higher.
Anything lower than that is simply not powerful enough. You can find these specs in small lettering on the charger. Most cheap 3rd party launchers are 5V 1A.

I was one of the ones having problems with it needing to have the screen on to charge. It was a problem with the charger (yes, it was marked as a high amperage charger), changed to a different one (Anker 40W 5 port) and it's working fine.

Huge second on the Anker. I love that charger by the way. With various devices I would get irritated with some refusing to charge on certain chargers (my BlackBerry Bold in particular). I've since switched to the Anker 5 port 40 Watt and no longer worry about which cable I'm reaching for. Every device gets the power it needs with no fuss.

Initially i was using a belkin 2 port, 2.1amp per port charger, which would start charging but stop once the screen was off.

This seems logical, but it does work when i use the genuine charger from my sgs3 which is a 5vdc 1a charger. Takes all night to charge, but charges non the less.

Thanks for the info mate, ill see if i can get hold of one of these in australia, that being said, it appears that these are also 5v rather then the 5.3?

That's because the retention rate of the S3's charger is higher than that of a generic cheap 3rd party one. Where the S3 charger actually delivers 0.8-1A, the cheaper ones usually average around 0.5A.
This is why charging over a usb 2.0 port without any power boosts also (usually, there have been some exceptions) doesn't work.
I usually charge mine with my Note 3 or S5 charger, as the three are all the same charger.
