Hello guys,
Like most of us Android users I had some previous phones that were Android powered...
So with Motorola Milestone I had a 12v car charger, I used it too much with it, now I have a Galaxy S2, if I use the Motorola's charger to charge my phone there will be any problem?
Thanks in advance!

I use my sony charger to charge my HTC evo3d.no problems so far.but iam not sure about Motorola

The important part here is the voltage the car charger outputs. I believe the standard Galaxy S2 outputs 5V (at 700mA [0.7A]). If the mA is lower, it will take a longer time to charge. If its higher, it will only draw from it what it needs.
So, check the output voltage of the charger is not higher than 5V and you should be ok.

Many thanks!
I'll use it now without any worries so!
Here is a question for someone who understands electronics better than I . I bought a dual port USB car charger that supposedly puts out 2.1a per port. It charges my devices but slower than expected so I am doubtful that it is delivering the promised amperage.
Is there an easy way to measure the amperage either at the charger, the end of a USB cable or better by using some app installed on my Tab?
Here is the link to the device on Ebay. http://www.ebay.com/itm/251037335263?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
Thanks in advance.

So I will get the regular charger for gs3 that comes with the phone (tomorrow when i get the phone). but i also have the HP Touchpad charger which gives output of 2.0A. I was wondering if I charge my phone with the HP charger will it actually charge is faster then the regular gs3 charger? the reason i ask is cause in other threads ppl have mentioned that it only charges faster with non - stock roms like aokp or aosp roms. please lemme know if this will work. thanks
It should I got one of those and it does charge faster I got the bb one tho

I've used my BlackBerry PlayBook charger on mine and it doesn't charge any faster. That charger is 1.8amp.
It will not charge faster. The phone only draws as much amps as its allowed to. Whether you use a 1 amp charger or a 2 amp charger, it'll only charge at the phones own rate
Sent from my SPH-L710 using xda app-developers app
then theres basically no advantage to using some other charger?
I don't believe so. The phone only draws what it needs.

A lot of chargers will be rated less than the stock charger. Especially cheap car chargers. In that case the phone can only draw at the charger rating.

Unless you run a custom kernel that allows for higher charge rates.

I have a dual car/wall charger and I noticed when plugged in the car it charges faster.
Sent from my vivow using Tapatalk 2
The values listed on the charger is the max output it can provide. If the setting on the phone or the hardware is set up to only pull 1A, then it will always pull that unless that is more than what the charger can provide.
That being said, you should be able to take the battery out and charge it faster separate from the phone. I've always read, though, that charging a battery faster ( i.e. turning up the current) will/may reduce the life of the battery

the only way I have found to charge phone's faster is to power it off and then charge...takes about half the time to fully charge
none of the 2 amp chargers make it any quicker

I have a Touchpad charger and it can be used, though I noticed that the phone got hotter than normal, IMO. The phone comes with a 1.0A combo wall charger with USB cable. Interestingly the Samsung stand and battery charger that comes with the spare battery comes with a .7A charger but the charging unit itself is 500mA/1A on the input with output at only 4.2v @ 450/900mA.
I dont know whats getting worst.
But whats the best replacement charger for xtz that has a higher amps? I already looked in amazon and most of it has a 2a dual and i still want to ask the community
And guys if possible please suggest those has a long data cable

I cant wait for the next update on XTZ, something like .67
Displa, camera, battery and some tweak, not sure.

I'm not saying it's the best, but I've been using an old iPad charger (2.1A) for the last 2 months without any problems. I plug the charger into a mains extension lead so I don't need a very long USB lead.
Well i have an iphone5 charger here it says output 5v---1a
Is it ok to charge thendevice with it?

Any USB wall wart that is 1.5 amps - 2.1 amps (1500 - 2100 mA) @5 volts will work. The more amps the faster it will charge. In a pinch you could use a 1000 mA charger, it will just take longer.
Alright im confused.. Which is faster mA or A?
And by the way im not asking about the power here but a replacement.
Thanks for the infos though

1000 Milliamps = 1 Amp
1500 mA = 1.5 A
2100 mA = 2.1 A
Pop Quiz: 5A is how many mA? _____
5000mA is how many A? _____
Often wall warts list output in milliamps
Some external batteries list output in Amps.
It's not hard to convert between the two.

Congrats, you passed electricity 101.
Keep in mind that batteries can be fickle creatures. Sony delivers the XTZ with a 1500 mA charger. Based on that alone, it's probably best to replace the original charger with another 1500 mA charger. While you can certainly use more than 1500 mA and it will certainly charge faster, in the long run you may end up shortening the battery life. There are only so many charge cycles to be had in any given battery and quick charging can put an extra strain on a battery that wasn't manufactured to suck up power that quickly.
In a pinch, use whatever you have on hand or can find. For everyday charging, its best to default to what the manufacturer recommends.
The Apple 12W one works perfectly fine and charges the tablet so much faster!
There is people here saying it is impossible because of battery electronics.
It's quite simple: They're plain wrong.

Without doubt the best charger I've used for the money. It keeps up with battery drain on heavy use (Full HD video+Net+ others...at the same time) Stock charger does not. At first glance it does seem expensive but does the job very well.
I sent Sony a link to the Apple website for these as it's much better than the POS charger they give you with their £400 "Flagship" tablet. Well worth the £15 price tag.

Well, yes and no. Watts, Amps and Volts are all different measurements for different things and it can be quite confusing to figure out to the uninitiated. Watts is a mathematical calculation based on Ohm's Law. Watts = Volts x Amps
All USB devices accept a maximum of 5 volts. USB standards cap the max power delivered to a device @ 5 volts. Most standard USB ports deliver 5 volts @1 amp. Newer computers and specially designed charging ports can and do deliver more than 1 A via USB but they all deliver a maximum of 5 volts.
12 watts divided by 5 volts = 2.4A
If you look at your charger you'll see the output amps listed as 2.1A or 2100 mA.
Sony's included charger only delivers 1.5A or 1500mA, so yes it charges slower and when the tablet is under high load, has a hard time keeping the battery at 100%.
The real concern here, is what effect does delivering 2.1A of current to the battery day after day have on the useful life expectancy of that battery? I don't know the answer because I don't know anything about the battery that Sony uses. It's possible, if Sony, used a top quality battery, that charging with 2.1A will have no effect at all and Sony just wanted to save a buck or two by including a weaker charger in the box. On the other hand, Sony may have deliberately used a battery designed to accept 1.5A and included an appropriate charger.
As I said in a post above, apart from the battery overheating while charging (if it wasn't designed to charge @ 2.1A) and a reduced useful life of the battery, there shouldn't be any real problem using a "slightly" more powerful charger - up to a point. Charge with too many amps and the battery will probably explode or at the very least melt, potentially causing a fire if left unattended.
When talking to Sony, the question you need to ask, "Is the battery rated for 2.1A or only 1.5A?"

That i can agree with and it's a risk i am willing to take. There is people who say the 2.1A charger wont affect charging time in a positive way at all. That's what what i refered to when i said it's not true.

Definitely. More current (which is what Amps measure) means faster charge times, as long as what is being charged can accept the current being provided. You should be fine, but what do I know. PM me in six months and let me know if your battery still last a reasonable amount of time - then we'll know.

You're kinda right, but kinda not....
The charging circuitry inside the tablet is what regulates the charging current, not the 'charger', it will have min and max currents (the thing we plug into the wall that we all call a charger, is really just a power supply, there's no charging circuitry inside it.) That's why it doesn't charge from a standard usb port (which is 500mA) so, if it's charging faster with a 2.1A power supply, then it's obviously designed to do so.
Let's say, for example, the tab can accept a charging current of between 700mA-2.5A. Obviously, the charge time will be slower at 700mA than 2.5A, however, if you were to plug in a 5A power supply, the charging circuitry in the tablet will still only draw the 2.5A its designed to. So, don't worry about giving it too much, it's not possible.
Now, I don't know what the min and max charge currents are, but I can tell you that mine will charge (very slowly) from a 700mA LG charger.
And also, the dock for the tablet states an input of 1800mA,
So, we can assume the min is at least 700mA and the max is at least 1800.

technaudio,
That's my age showing. Back before some smart guy invented the wheel, we gave a device power and if we gave too much a fuse would blow. I didn't mean to imply that the charging circuit was contained in the wall plug but at the same time, I failed to appreciate that the Tab was designed to prevent an over current situation.
...now let's see what happens when I give this puppy 15A AC...damn, melted the usb cable...
@dph3055
I knew what you meant, but some others on here probably wouldn't.
I've seen a lot of threads saying using a 'too powerful' charger will damage the battery.
It just won't.

I got my phone today, and one of the first things that I did was test all of the Chargers.
My first thought is that the one plus cable that I bought is very high quality. Every charger that I tested, it charge faster than the cheapo ones that I bought on Amazon.
However, what I've been consistently surprised with is that using the same cable this phone charges faster on a Qualcomm quick charge 2 charger than it does on a standard USB charger. I've tested this with all sorts of Chargers around my house and I'm consistently seeing around 1500 when connected to a quick charger, and only a thousand when connected to a standard charger.
The USB C charger that came with the phone is significantly faster. However I wanted to share this so that for those others who bought all sorts of Qualcomm quick charge 2.0 Chargers, don't throw them out. They're still better than a regular charger.
Yeah on a good USB 3.1 cable (nice and thick) with my standard quickcharge charging block (7 ports, 60W total IIRC) I get 'charging rapidly' and it charges better than 1% a minute - about the same rate my N5 did on a much smaller battery. I've still not taken the google charger out of its box yet.. Need to get around to testing it even if I can't see myself using it.

I am curious as to what "standard" chargers you are using. I have a wall charger rated at 5v 2.1a (non-QC) per port and a car charger rated at 5v 2.4a (non-QC) per port, and both of those charge at 1500ma. Is it possible that your "standard" chargers are only rated for 5v 1a output?

Bought that one though still waiting on my phone. Like that it has micro USB too for other devices. Charges my HAM2 very fast.
Your results have nothing to do with them being QuickCharge bricks, I have a inline amp meter and I can get 1.5 on any brick with an amp rating high enough, not just my QC bricks that I was using with my Moto X. At least people will know if they have a QC brick they'll get at least that though.
I didn't know this thread existed. I'm getting what I think is pretty poor performance from the stock 6p charger. Please see this post:
