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"

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.

Why not?
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.

I'm using a 2A as my car charger works perfect.

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...
"I know that my English isn't perfect, but I still hope it's comprehensible." Send over the cool Xperia Z
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.

Hi everyone.
I recently got the Xperia Z and noticed the original charger packs a 1500mAh speed (which got me confused because I thought AMP referred to charging speed), but anyhow. I also bought a power bank (external backup battery) and the thing has 2 ports, 5V 1AMP and another 5V 2.1AMP. So I was wondering if the Z can take the 2.1AMP speed without damaging the battery. What do you guys think?
Thanks.
You won't harm it instantly no. Over time, yes.
The battery lives better if you charge it slowly, I charge mine with 500mA when I go to bed. I'd use the 2ma if you were really rushed.
My Stock charger is 1800mA btw. (Dock)
The phone will automatically limit the charging current (amperage), so the battery won't be charged too fast even if you use a 2A charger. I do not know at what amperage the XZ limits the current, but I suppose it's somewhere around the 1500mA of the standard charger.
On the other hand, charging with very low currents may also damage the battery. I read somewhere that prolonged use of a charger with less capacity than around 0.5c (c=the capacity of the battery; 2330mA) might be bad for the battery. Therefore it isn't recommended to only use the USB port of your computer (500mA).
So, for repeated use over long periods of time, a charger with a capacity of over 1165mA (0.5c) is recommended.
Well I don't know what to believe anymore :x
You can safely charge with almost any trusted-brand MicroUSB charger. As long as it's not broken or a cheap chinese knock-off or anything like that. It will output only as much as the phone will accept.
EDIT: 2.1AMP (as you state it) is 2100mA (milliamperes). That's it's current output. It does not refer to "speed" per se, but a battery will charge faster with a higher output charger. A 1000mAh battery will charge from 0 to 100% in one hour if you use a 1000mA charger. Or in half an hour with a 2000mA charger. That's the theory.
In reality, phones and batteries will have safety circuits that limit the charging current so that the battery won't get damaged. It simply will not charge faster than what's safe. If, say, our XZ is limited at 1500mA, then it won't let in more than 1500mA. No matter if the charger is rated at 1500mA or 2000mA. The phone will, however, accept less than 1500mA, but when the current sinks below a certain limit, the phone won't charge at all. That lower limit might be somewhere around 400mA. If your computer's USB port gives out considerably less than 500mA (which is the norm), then there might be something wrong with the port and the phone won't accept it.
For comparison, the Samsung Galaxy S II won't charge at any higher than 700mA. No matter if you connect it to a 700mA or a 2000mA charger, it will only take 700mA and that's it. The stock SGSII wall charger is 750mA.
The XZ, having a bigger battery, will charge at higher than that. I'm guessing 1400-1500mA because the stock charger is 1500mA.

Awesome then, thanks a lot for your help
Let's face it. It's always best to go with the original charger. If you use a non standard charger the best practise is to use one that has a similar amperage. That said, my Power Bank case puts out 1amp via the dock pins, so... And it's made for the Xperia.

Ride it like you downhill it.
My original charger is very slow even if it says 1.7 amps .i use my original htc ine which says 1amps and it works well.Is it only me?in my original charger it never goes beyond 500-600 mA
My charger is rated 1.5A and does the job fine.Have also used an old 1A BlackBerry charger and a Samsung Galaxy/Note 2A charger without any probs.
so this combo is working for me:

the latter also allowed me to fastboot oem unlock.
so battery is at 59%, homescreen says 14 minutes till full.
cheers
can you please check with Ampere or GSAM for the charging speeds that you achieve?
does the device say fast/rapid charging?
Interested to hear the results from Ampere or GSAM as well
i cant get a good handle on how ampere works. it keeps measuring, takes forever, and fluctuates a lot.
with the aukey combo, i got 1830/2050mA @ 4.14v, at 53%, 37.7c
took it off charge for a while and tried again with the stock charger:
with the stock charger, i got 1850/1860mA(min/max) @ 4.159Vat 61%, 30.7c
I will try again at 50% today if I have time but I am pretty pleased with my little aukey combo. It was cheap.. I got it when there was a 7 dollar coupon floating around.

Yep that would be the one. charging at 1800mA is not the fastest that the phone can charge at though. I'm going to hold off for the ones that enable the full speed of charging

From the product description, you are only going to get 2A out of the charger. 5X doesn't do QC2.0, so you will only get the output at 5V, which for this charger is 2 amps.

Output: 5V/2A, 9V/2A, 12V/1.5A

But some Aukey chargers with AIPowertech like this one "charges all non-Quick ChargeTM 2.0 phones and tablets at their normal speed (up to 5 volts / 2.4A Max)with AIPower Tech Technology."
I've got the charger, just not the cables... so haven't been able to test.
I tested Aukey PA-T2 wall charger QC2.0 port ( orange one) on a Sony Xperia Z3 compact tablet
I recorded charging current up to 2.7Amp with the Aukey USB cable and up to 3.0 Amp with the Sony USB cable !!!! far more than the 2.0 Amp level current Aukey specifies......
The voltage - current output test show that the voltage stay in the 9.0V range with current up to 2.4Amp then fall down very quickly. It seems that the voltage stay at a value enough to deliver up to 3.0 Amp charging current to the tablet ....

LOL, thanks... but that doesn't really help this 5X cause. Given that there is no quick charge on the 5X, it'll remain at 5V. The question is whether it'll pull more than the 2A or 2.4A specified on these chargers at 5V on a 5X.

Aukey quick charge 2.0 behave like a standard charger when connected to a non QC2.0 compatible device. The output voltage will stay to 5V so the current level will be very sensitive to the quality of the USB cable and limited by the maximum current the device will afford.
In practice it is very difficult to reach 2A charging level ( even if the charger is able to deliver such current) with a voltage output of only 5V , due to losses in cables and connectors
From my experience the higher current charging level I obtained was with a Samsung wall charger refence EP-TA10EWE which deliver an output voltage of up to 5.5V at 1.9A ( nominal voltage is claimed at 5.3V)
I got 1.7Amp charging current on my Nexus 5 while with the Aukey QC2.0 the current was only 1.1 Amp in exactly same conditions ( these recorded data are also reported in my blog .....in French.....)

Thanks, didn't think to look at the link.
I wonder how older phones like the NA Galaxy S3 and Nexus 4 that both have QC1.0 ([email protected]) compare to the charging of the Nexus 5.
I'm curious as to how you did your testing, as I'm going to try my own testing once my cables come in. Did you drain all your phone's battery to 0 before performing each test? Phone airplane mode vs off? I also think that all tests must be done in relation to time, especially since the charging profile changes as the phone charges. I'm also curious as to how the non QC port on the Aukey performs, since it's spec'd at 2.4A @ 5V.

All tests are made with battery drained to zero before starting , and a complete charge is done in each conditions. That way I can check that the full charging time is logically related to the recorded current values. The current is recorded during the complete cycle at a frequency of one value per mn.
The air plane mode was off.
Aukey QC port and non QC port are slighly differents when connected to non QC2.0 devices :
QC port delivers 5.1V in open circuit, the voltage encrease to 5.2V at 2.2Amp, on the contrary the non QC port delivers 5.2V in open circuit and decrease to 5.1V at 2.2Amp. I did not test them at higher current level.
I did not tested Galxy S3 or Nexus4 , but I beleive that a charger like the Samsung EP-TA10EWE will deliver them the maximum charging current they are programmed to accept, as obeserved for the Nexus 5.
I got the same charging current curve I recorded with Nexus 5 and Samsung EP-TA10EWE, with other set of charger and cable. This means that this charging curve is defined by the Nexus 5 inner program , not the charger characteristics. The problem is that we never know which is the max current curve internally programmed for each smartphone...... so it could be a long way to find it.......
