Hi everybody
Unfortunately I lost my charger for my XDA neo.
The thing is, that I do have two other USB-chargers for other devices but I am not sure if I can use them with my XDA neo.
Charger 1 (originally for a BenQ MP3 player):
Input: 100-240V ~50/60Hz 0.05A
Output: 4.2V - 110mA
Charger 2 (originally for a GPS device):
Input: 100-240VAC 50/60Hz 0.2A
Output: +5.3V - 0.5A
I think the sticker on my XDA neo says 5VDC - 1A and on the battery it says 3.7VDC - 1200mAh.
Does anybody know if I can use one of the chargers or would I damage my device or battery?
Cheers for your answers!
Well i bought this. 4 dollar and it works....
http://www.dealextreme.com/details.dx/sku.2381
Its a usb charger for european use.
And it works like a charm
details of the adapter are
Model sysb51a
Input: 100-240v
OUTPUT: DC5.0V
1000MA +-5%
i think u have to try but always be carefull with charging equipment.
do it matter?
i never looked @ volts or anything else...my o2, brother moto rokr, sister moto razr & sometime, brother old lg phone...all of us share the same charger....
Bought my Nexus in the US this summer, really enjoy this little beast.
I have a question regarding charging. The provided charger is a 5V- 2A charger but a US one. I have at home a HTC one X charger which delivers 5V - 1A. Can I use this charger ? What is the difference between 1A & 2A ?
Thx, Yves

I don't see how less amps would hurt it. It may not register a charge, or charge very slowly. I would wait for another opinion.
2A will charge faster than the 1A charger. That's the only difference.

On the flip side, can I use my N7 charger to charge my mobile (SG2)?
My SG2 charger is set for 0.7A, while the N7 charger is set at 2A.
Mine charges with the USB cable i use to transfer files, which is about 500mA. Works but slow.
checking around the net, that's what it say.
the USB port have a maximum of 500mA i believe. And i did noticed it tend to charge more slowly. While the provided Asus charger with USB port on it, it have 2000mA (or 2A). So i guess the Nexus 7 is made to be able to support up to 2000mA, while it will charge more slowly when connected to a computer's USB port.
I took out my PSP and its charger recently, and this charger is also 5V, 2000mA, except it's a round tip made to fit the PSP charging port.
I do have another 2000mA charger, it also have a round tip, luckily it fit on my Ainol Elf II tablet. I got this charger/power supply when i bought my HDMI switcher, it work without it, so it was sitting there for all this time, unused.
i'm gonna try charging it with the provided Asus charger now.

Yes. Your phone will not charge at the same rate as the N7, however.

Hi all,
Ok, so I finally managed to order a 16Gb Nexus 4 and hopefully it will be with me in 1 week or so.
And I was wondering one thing regarding the AC adapter: I believe (pls correct me if I am wrong) that the original AC adapter’s output voltage is DC 5V, 1.2A.
I will need an extra AC adapter to keep it at work and I was planning to use one of those:
- The Sony Xperia P AC adapter will output 5V, 1,5A
- The Samsung Galaxy S AC adapter will output 5V, 0,7A
It is clear that neither of those 2 chargers will match exactly the specifications of the original Nexus charger (same voltage, but different amperage).
So, here goes the questions:
1) Is there any problem if I use a charger that will output the same voltage but with different amperage?... if not, which one would you use and why?.
2) how the amperage affect to the charging process?.
Thanks all in advance
PS: sorry for terrible English
You can use any charger up to 2 amps.

You must use a 5V AC USB Adapter and better no LESS than 1A
for Fast Charge.
AC Adapter I Use:
iPad AC Adapter 5V 2.1A at Work
PlayBook AC Adapter 5V 1.8A at Home 1
Original Nexus 4 AC 5V 1.2A at Home 2.
Our Nexus 4 will Draw around 0.8A when Batt lever at 0% - 80%,
then around 0.5A at 80%-95%, Final State 95%-100% will draw 0.2A roughly.
When 100%, Nexus 4 will use the AC power & the Current "A" show on phone
will like 2mA (0.002A) when idling.
** 1A = 1000mA
As previous poster said, do not go under 1.2amp.
I run the OEM charger in my bed room, a USB charger to my computer, and a 2.1amp charger in the car.

Why do you say not to go under 1.2A? Charging from a laptop is at .5A. I've been using a 1A charger since day one. Haven't experienced any issues with it.
Charging at a lower amperage shouldn't hurt anything, just charge slower. All you have to do is make sure it's a 5V charger. Amperage shouldn't matter but a lower amp charger will charge slower. As for a higher amp charger, the phone will only draw the amount of power it needs to charge so using 2A charger won't hurt anything either.
Also 2mA is 0.002A not 0.02 A

Since the charger doesn't actually regulate the charging itself (the phone does this) it doesn't matter how many amps it can supply, could be 100 amps, no worries. As long as it is 5V, the phone will draw as many amps as it needs.
Since the supplied charger is 1.2A rated, it's fair to assume that the phone will never actually try to draw any more than that, so there will be no benefit in going higher.
Going for a lower current charger will likely extend the charge time.
I use a 2.1 amp daily without any issues.

Wow guys!!... thanks all for your answers!!
So, if I understood correctly, the amperage will only affect to the charging time, meaning that by using the Xperia P AC adapter (1,5A) the battery will be charged faster that using the Galaxy S one (0,7A)... right?
Pls allow one last question: a few yeard ago, I think I read in some forums that a slower charging process could help to keep the batteries in the best conditions for a longer time... is this still true with modern batteries??
Again, THANKS all for your help!!

Yes, the .7A charger will take a little longer to charge you phone.
On the other answer, I think NO but I'm not as familiar with LiPo batteries. I would venture to say that .7A vs 1.2A (max the phone will draw but I think someone above mentioned it's even less than that when the battery is very low) is not going to make a bit of difference in your battery life.
One thing I do know about LiPo's is you do not trickle charge them. So while plugged in it will charge at the rates mentioned above until full and then it QUITS charging all together. Once the phone discharges the battery to a certain level, it will charge it back up again. Probably at 98-99%.
There may be one other thing to consider when selecting a third party charger. In the Nexus 7, the device looks for pins 2 & 3 (data) of the USB plug to be shorted in order for it to draw full current. If this pins are open (or have a load across them as is the case with iPhone/iPad chargers), the Nexus 7 will assume it is plugged into a computer and limit its draw to 500MA.
Not certain the Nexus 4 behaves the same way but would assume so.

setzer715, thanks for the answer... I think I will be using the Xperia P charger at work...

I want to make this case clear. According to my Charging log,
Here is some key point.
Nexus 4 Max Draw Rate at Fast Charge Mode is around 800-900mA,
even you use a Charger that rated at 1A (iPhone Tofu), 1.2A (Original),
1.8A (Playbook), 2.1A (iPad).
Fast Charge Mode must be with Charging Cable with 2&3 pin Shorted,
or the charger itself have the 2&3 pin already shorted.
Therefore, 1A is a Sweet spot for getting Charger & Charging Time for
Li-Po/Li-Ion/Ni-MH Batt charging.
If you use under 1A Charger, eg 700mA or 500mA, it will take much longer
to charge the batt but no harm as well. Just too slow only.
The stock charger that came with my phone sucks, I use one from my epic 4g touch (gs2)and it charges much better
DEVICE: Nexus 4

Left a phone on a charger all night with a long (10ft) cable and it couldn't even charge the phone over night. I know a 10ft cable will slow things down but my gs2 plug has no problem charging my phone. Search around and you'll find a few fail stories about the stock LG charger.

Hello.
I lost my Nexus 4's charger, Is it okay for the battery to charge it (for a whole night) with iPhone 6's adapter?

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?
Thanks .

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.

So if I will charger my Nexus with the iPhone charger and it is 2A it won't charger my phone faster?
The phone will allow only 1.2A?

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).
hello;
i have just bought LG G2 (F320L), i have noticed that if i charge the phone with a charger having 1amp output specification it charges rapidly.
So the question is that what charger output specifuication is best for Lg G2 which may charge the phone rapidly but does not damage the battery.
U can use a 16a charger if u want. The charging circuits in the phone handles the input so max the phone will use is 1.6a. It's li-po cells the phone has som advance circuits handling the balance charging of the cells. Recommended is 2a charger but don't forget the cable.
If u use a chappy cheap cable it won't go above 0,3a use a premium and u whill have a 1.6a charge. 1a is to little and to slow.
The phone handles the power to optimize the charging so don't be afraid to use a powerful charger just make sure it's 5v and above 1.6a. If u bye a 1.6 the charger itself will be on max load and generate a lot of heat with could damage the charger and the phone so go with 2a and a premium cable
I'm pretty sure the post above's first reference was meant to say 1.6A and not 16a (the second reference was corrected). 16A wouldn't necessarily hurt the phone actually since current aka amperage is pulled and not pushed - the device would still only take what it needs as long as the 5VDC is solid.
Anyway, enough rudimentary electronics and electrical theory...
Any modern USB wall charger will work with the G2 without issues, obviously if you can get and use one that provides a higher level of amperage/current it will charge the G2 faster up to about 1.6A as mentioned above. The factory charger included with G2 smartphones is designed to provide 1.8A but the G2 won't necessarily pull that much - the .2A is a little headroom and the charger doesn't "stress" as much to provide the 1.6A.
Lower amperage/current chargers just mean it takes longer to charge the G2, basically. As it has a 3,000 mAh (that's 3A for the record) that basically means with a 1.6A charger attached and the device powered off and charging exclusively you'll get a full charge in just under 2 hours from a near-empty state - if there's a charge on it already then it'll charge at roughly 1% every 2-3 minutes, maybe a touch more if the G2 is powered on and charging.
Either way, again, any modern charger will be fine. Try to get at least a 1A model from whoever, and avoid really cheap ones that can't do 1A minimum. If it's a brand name charger (Apple, Samsung, LG, Motorola, BlackBerry, etc) you'll be fine.

thank u for making it clear,
is there any way to measure output of any charger?
i know its not related here but just for fun.:laugh:
currently i am charging my G2 with 1A charger but it takes so long to reach 100% charge, may be about more than 4 hours.
Actually I meant 16a.... Just get a 2a charger and not a cheap one.. Expect to pay 20$

Once I ordered a 2a charger from China.. Output was 200mah and it almost melted. 2$
U can measure how mouth the charger provide.
Easy way is to use a app in you phone. But not 100% accurate.
Hard and accurate way is to use a USB extender cable that u cut the + cable and use a ampere meter. But u have to use a high end cable for that and u don't want to cut a perfect god cable in half
So I recommend this app https://play.google.com/store/apps/details?id=com.manor.currentwidget
