does lg optimus x2 compatible with ipod touch wall charger rated 5.1V 1A or samsung android charger series with 5.1v 750mah?
please share volt and ampere rate on original charger or share your experience using wall charger other than original
thx
original charger: 4.8V/1A
with one charger that puts out 5.3V/1A the touchscreen starts to act weirdly
The charger (from a motorola RAZR II V8) I mainly use puts out 5V/850mA

samsung Galaxy S? does it rated 5V and 850mah? okay so it seem wall charger from samsung galaxy series work fine,tommorow i will go to store to buy them, Original LG charger is expensive in here 14$ and there's chinese micro usb wall charger for 3$ that works fine dont know it's volt and mah rate
thx for answer:laugh:
got samsung traver charger adapter for 5$ rated 5v 1A it charge fine without problem.it say 5v 0.7A on the package maybe it's a fake or half fake/third party but still no problem
Building on the topic, I would like to know if I use the original charger but with other cable USB (commom) I will have same efficiency in recharge? And I would like to know if I will Have problem if I make this?
dont know about usb cable maybe yes,my only experience just with generic usb cable that dont work as data cable in sgs
I have numerous chargers at home all of which have charged my evo, gs2, Nexus 7, etc.
Can these be used interchangeable in the Note 2 without harming the charging process?
Thanks
As long as the Voltage is the same (5V) there is no Problem. But you should have a charger at 2 Amper for optimal charging speed.
I just tried charging mine with the normal microUSB charger I use for every other phone I have had and it took 7.5 hours to charge from 5%-62%. I used the stock charger that was in the box and it charged it in 3.5-4 hours no problem. Seems like the charger in the box charges faster.
reading this thread made me curious, my NOTE II should arrive in about a week, I can't tell for myself yet, what is the A (amps) specification mentioned on the original charger?
as i come from HTC, my current chargers go up to 1 A current. witch is the double A a standard USB port will give unless crossover'd .
thanks in advance!
----
in the wiki thread i found the answer, the supplied charger delivers 5 V 2 A output to the device.

2A! Same as the Tab 10.1 charger.
Filling a 3100mAh battery requires some grunt.
i think even the usb cable makes a difference..
when i use the stock usb cable with the stock charger ..my s3 would charge up comparatively faster than with the other usb cable connected to the same stock charger.:rolleyes

It certainly does! :good:
All electrical cables have some resistance. Very low (but not zero) for quality cables, sometimes quite noticeable for thin and cheap offerings.
From Ohm's Law we know that voltage drop will be proportional to current. A cable with a resistance of just half an ohm will loose about 0.5% at 50mA. That's pretty much nothing. However, at 2000mA the loss reaches 20%.
dude use any charger, just don't use LG charger **** !!!!!
You must use the 5volt 2amp charger and cable provided or a replacement with the same output or youll either be waiting for ever for it to charge or do some damage.
I tryed using my note 1 charger rated at 1amp and guess what? It took about twice as long to charge.

Some of my old 1 Amp chargers aren't happy at all, and will often decide to stop charging randomly.
I though it was something weird with my phone, but after switching chargers it never happened again.

USA official charger
This are the images of the official USA charger that will comes when they release the device in USA
And yes its a 2.0A charger, so the SIII charger isn't appropriate for NoteII.
this is the kind of charger used in Canada, USA, and Latin America, i bought this NoteII in Mexico from an authorized Samsung provider, of course factory unlocked 710usd, like 10,900mxn.
Has anyone tried a 3A charger? Just wondering if this would speed up charging even more than the standard 2A charger.

No, it won't speed it up. It's what the device takes from a charger, and not what a charger can potentially supply. If the device's charging circuit is spec'd for up to 2A current, that's what it will suck out of a charger, not more. You can connect a 30A lab power supply, and it will still be the same 2A (or less) input. To speed up the charging process, you need to mod the charging circuit of the device itself.
My Note 2 charger says....
Input : 150-300 VAC 50-60Hz 0.35A
Output : 5.0V = 2.0A
Can i charge it with with following chargers....?
1. Note 1 Charger
Input : 100-240 V 50-60Hz 0.15A
Output : 5.0V = 1.0A
2. Iphone 3G Charger
Input : 100-240V 50-60Hz 0.15A
Output : 5V = 1A
3. Logitech Harmony Remote Charger
Input : 100-240V 50-60Hz 180mA
Output : 5V = 1A LPS
So can i Safely charge my Note 2 with any of the above chargers ? Or will charging with any charger Harm/Damage my Note 2's battery/internal components...?
Thanks.... :fingers-crossed:
As long as the Amper on the charger you use is lower than 2 there is no risk.
Voltage should always be the same or else it will damage your phone. (5volts = USB standard voltage)
If you use a 2,5 A charger the note will charge faster but will heat and damage the battery.
If you use a 1 A charger the note will charge twice slower than with the 2A charger but this charge will last longer because slower charging gives a little better battery life When I charge the note on USB 2.0 (0.5 A) / 3.0 is at 0,8 ampers it takes a whole night to get around 90% but my note lasts usually a little longer than when I fastcharge with the stock charger (one gets lazy to charge when a battery lasts so long lol...)
You can in theory use those other chargers but the charge time will be significantly slower, probably double the time. I used my nexus one charger which I use to charge everything in my room and I got an error message saying that I needed a stronger charger. You may get that message as well on those 1A chargers. I have been successfully been able to use my 1.8A blackberry charger with success though as well as my 1.5A griffin at work but I shorted the pins on the cable I use on that charger.
Like I said you can maybe use those other chargers but you may get a power message. You're best off with the stock charger.
use everything. "Just don't use LG chargers"
regards
From what I understand through research, It doesn't matter at all. Stay around the official amp voltage range. If it is a bit high, the phone will regulate how much power it draws from the charger. If it is a bit lower, then expect slow charge.

I am using a Galaxy S III charger, I guess I am not causing any harm with that... ?
You can use any charger that outputs at 5 volts. Even if the charger is 5 volts 10amps. The phone will only draw as mu current as its built to draw and no more than that.
Been using my s2 charger since I got my note 2 with no trouble at all. I also sometimes use my HTC desire charger and again no trouble here.

Hmm I thought changing the voltage makes the difference in how much power it draws (and puts into the battery) and the amp rating is how much power the charger is meant to give. So if the phone uses up 2 amps at 5 volts, then it could overheat a charger rated at 1A at 5 volts.
That's how powering something like LEDs works. If an LED is rated at drawing 700 ma at 3.3V, a power supply rated at 3.3V and 700 or higher will work - it could be rated at 2,000 at 3.3V and the LED would still draw 700. If you raised the voltage to 3.7V, then the LED would consume more than 700mA and would be brighter, if it's made to take the higher voltage.

This is correct. As long as you are using a standard USB charger, which will output 5v, you will be fine. The amperage will determine how fast your phone will charge. A charger with an output of 0.5A (500mAh) @ 5V, which is equal to 2.5 watts, will charge your phone slower than a 1A @ 5V (5 watt) charger.
No need to worry about hurting your phone with a higher amperage output. Your phone will only use as much current as it can handle. If it is rated to draw 900mAh @ 5V, doesn't matter if the charger can output 1A, 2A, or 5A, the phone will only draw a maximum 900mAh.
I bought some Palm microUSB charger during their liquidation. These days I dont even open the chargers for any phones I buy. Infuse, Xperia Ion, Focus, Exhibit, Note 1 all of them charge fine with it.

Hi
If the voltage output of a charger is less than 5V (let's say 4.5V), will this hurt the phone & battery?
Note 2 isn't that picky on charger.
I have several off-brand 5V 2-3A chargers and all of then just work fine.
Glad I'm not the only one using a random charger... The ones phones come with, the cords are entirely too short.

This is exactly what I am going to say.
Yes, its perfectly safe. I've used my iPad charger to charge my note 2 before, because it charges at 10 volts intsead of 5 so the phone charged faster.

I use whatever charger is available and fits. Have for YEARS. You guys worry too much about crap. It is just a phone, if it breaks, I'll buy a new one. Never had a problem though.
Using other device's charger is usually OK. But...
- An iPhone charger will work but because apple doesn't use the same standard to signal a USB charging port, you will be limited to 500mA (i.e. slow).
- Using another phone charger most of the time but because they are usally rated 1A instead of 2A it will charge slower.
The Note 2 seems to be quite picky about chargers and cables, for example, I couldn't get a full charge with cheap micro-USB cables from eBay and my old Nexus One charger. The best IMHO is a quality 5V charger that does at least 2A and follows the USB charging port convension of shorting D+ and D-.
More than 2A is not a problem because the device will only use as much as it needs. However if it is less, as the phone will try to pull 2A, the voltage will drop bellow the acceptable threshold. Usually the phone can adapt by charging slower but for some reason it didn't work with my Nexus One charger (1A).
Hi,
I've got my phone with samsung's charger of 1A (bought it from an open store locally - it was the cheapest), so I ordered a Sony Ericsson charger of 1.5A which charges up much faster..
My question is, could it goes even faster?
I've seen some Galaxy Note 2 and S 4 charger of 2A like these:
http://www.ebay.com/itm/2A-USB-Wall...S_Cell_Phone_PDA_Chargers&hash=item5658d7a0bd
http://www.ebay.com/itm/OEM-2A-USB-...l_Phone_PDA_Chargers&var=&hash=item51aabf953a
Could our phone handle it and charge it with the whole 2A power? could it ruin the battery with that high Ampere?
I'm asking this because I've ordered a docking station like this:
http://www.ebay.com/itm/261247762140?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
Which says 1.6A, so I was thinking perhaps theres stronger chargers out there for it..
Thanks!
im not sure about this but i believe the charger that comes with the phone is a 2 amp charger
It can handle 2A through USB port.
Via the charging dock, it can take 1.8A. Is that dock you are linking to an original part?
I have two DK26 docks and both say 1.8A, not 1.6A. Although if you connect a 2A charger to the dock, it'll be fine, it just won't be using the whole 2A input.

The Dock I've linked is a chinese copy, not the original, the one says 1.6A on description on Ebay, Does your original DK26 dock comes with charger too? What input and output is it says on each one? (picture could help much)
Also, how do you know it can handle 2A through USB? is that for sure?
Thanks for both!
The docks come barebone. No chargers included.
The charger included on the box of the phone is rated at 1.5A.
I have a Nexus 7 2A charger and an old Nokia 1.2A charger aside from the included 1.5A charger. All work fine either via USB or via the dock.
I can't notice any mayor difference on charging times, though. 1.2A charges almost as if not as fast as the 2A one. Iphone's 1A chargers do seem to take like 4 hours to charge the phone compared to the standard 2.5h I get from other higher rated wall chargers.
There are no 2A Sony chargers as of now.

It should handel 2.A but I won't remand it. I don't think it's good for battery. But one thing is pretty sure. The phone will heat more up as the charging circuit have to dissipate more excess power. Can not affirm it as I don't exactly know it's made but I'm just saying...

The downside would be possibly shortening the usable life of your battery, because the higher amp charging will likely heat the battery to a higher temp.
There's no free lunch.
To me, waiting a bit longer for charging is worth it to ensure the longest charge cycle life, particularly since the battery is sealed into the device. If it was a cheap and easy replaceable battery, maybe.
Amps don't matter unless it is lower than the specification
Think about your car battery having 700amps but your car stereo is fused for 20amps. Your car stereo gets its power from the battery directly. There is no power regulation. Your device will take only what it needs. It won't effect the life of your battery. Think about the charger you plugged into the wall socket. A wall socket can generate enough current to melt metal. Lower power draw is cooler but really just make sure the voltage rating matches and the amp rating isn't too low. USB should be 5 volts anyways. The big issue with amperage, can the charger handle the draw? Example would be a 3000watt car amp drawing power from a 18 gauge speaker wire. It might work but the wire will heat up since it isn't designed to carry that much current.
In short for USB the charger amperage can be higher than the device needs but probably no less than 1/2 the rated amps for the device.
As above, you could plug in a 200A charger and the phone will still only draw the same current as from a 2A charger.
The amount of current drawn by the device is firmware controlled to protect the battery from heat damage.
The stock charger is 1.5A so the phone must draw no more than that.
It's all about cables too. I have a 2 amp TomTom charger hooked up to a 3 metre long USB cable but it charges slower than the standard 'in the box' charger Sony supply at 1.5 amp.
More cable and wrong core rating = more energy lost or wasted. I actually had to ask a sparky about this one, but it's true. Cable length, rating and core make all the difference.
For instance.
If you hooked up a 3 amp charger (I had one for an old phone) to a cable that can only handle 1 amp then you will only get 1 amp into the device, probably melt your cable too over time.
Honestly, the best bet is to use as near as dammit to the original rating on the included in the box charger. Electricity is a funny thing, it can screw your phone up in ways only time and noting the battery life will show.

I'm looking for advice on the quickest way to charge my phone.
With the stock (1.5MA) charger and cable I get about 1200mA current of charge
With a Mr Phone 2A charger it maxes at 1000mA charge current
With a friend's Galaxy Tab 2A charger it maxes at 1600mA charge current.
(Figures above were obtained using Battery Monitor Widget app)
So firstly I'm confused as to why the higher rated 2A Mr Phone charges less than the stock 1.5mA charger when the Galaxy Tab charger, with the same specs, is much quicker.
Secondly, what is the maximum current the M8 can charge at?
Thirdly, what have guys found to be the quickest way to charge? I was going to source a Tab charger as that seems to be very quick or order this Anker desktop charger: http://www.amazon.co.uk/Family-Sized-Desktop-Technology-External-Batteries/dp/B00EJA28ES
Check here at "Charge Time" and/or here.
The stock mains is Quick Charge 1.5, so the phone would charge faster than a 2A "non-Quick Charge" mains. If you need a faster charger, get a Quick Charge 2.0 compliant charger.
Edit: Don't think Quick Charge 2.0 mains are available yet. Have to wait for their release.

Quick Charge 1 is not part of a chargers spec. Only QC2 is.
There's no such thing as chargers that are quick charge 1 or 1.5
And that doesn't explain why a 2A Galaxy Tab charger is quicker than another 2A charger
