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).
Greetings! I was wondering what is the maximum rated input current of the Xperia Z. There's no indication of it's rated input current anywhere on the phone. The supplied charger is rated at 1.5A and I was wondering if a higher amperage charger above 5V 1.5A (such as of those catered to tablets/ipad) would charge the battery at a faster rate before investing in one.
Anyone with any experience using a higher amperage charger on the Z could advice on any notable improvements in charging time as well.
Thanks!
Used a Nexus 7 charger rated at 2A and it charged fine with no detrimental effects. Charging time is about 1.5, hours from 10% to full.

While increasing the Amps will result into fast charging... the bad part is that it kills your battery life overall.
I've tried Sony charger rated output 1500mA
and Galaxy tab charger 2A
phone on, screen off
in 10 minutes charge, both added , just the same, 10% juice.
may try it longer next time.

Great findings! I guess it's safe to say that there is no notable reduction in charging times even with the provision of higher amperage chargers, and that the Xperia Z's power management IC can only take in 1500mA at max.

Charging at higher amperage would generate more heat and this increase in heat would degrade the battery cells at an increased rate, thus reducing the lifetime of the battery in the long run
Well unless you value your charging time (or loss of usable time) more than the cost of premature replacement of battery, then quick charging is for you. Personally, given a choice, I'd rather not charge at a higher current unless necessary, especially when time is the essence. (;

I will post when I find the correct link.
Erm I'm fairly sure that whatever amp you use the phone will only draw a set amount I used a 2500mah charger with my old phone for two years no difference in charging time nor degraded battery life or iverheating , just meant I had one charger for everything lol
That's correct, it's impossible to over-charge or charge too quickly a device by using a charger with a higher current rating than the original charger. Current flow is a RESULTING property of a particular voltage applied across a particular resistance. Applying too much voltage will usually be detrimental, but you cannot SUPPLY too much current. The device will draw as much as it needs unless it is limited by the charger's maximum current rating first.
I've been using an old Blackberry charger rated at much less than 1000mA. It might take a bit longer to charge, but I love the long, supple lead that comes with it.

Can someone explain me this...
My Xperia Z came with (1) Power plug-adapter with USB port + (2) USB to Micro-USB cable + (3) Docking station.
The (1) has Output = 1500 mA written on it, the (3) has 1800 mA on it.
Questions:
Can the USB cable transfer more than 500 mA? From reading USB page on Wiki, looks like it can do 1500 mA - 5000 mA when not transferring data so I should not worry about the cable?
What is the point of including a 1800 mA docking station + 1500 mA power plug? Does the station only charge at 1500 mA when connected with that plug or am I missing something?
Thanks, sorry for noob questions

The charging chip it self support higher current by default, but the manufacturer chooses the charger depending on different factors, design of the phone, capacity of the battery and also their stock chargers available... they will choose the best charger to match... in most cases it will be rated lower than what the charging chip is capable of...
the charging chip has it's limits also... using regular USB cables will only provides the standard current... I've used same amperage chargers as the orignal but with different cable and charging was slower... when I switched to the original cable charging was faster and had the same time as original charger ( same amperage )
When you use the original cable and higher current charger then you will have faster charging...
My Xperia arc came with socket charger rated at 950mA and a car charger rated at 1200mA... and the car charger is really faster but only when I use the original cable, when I used a longer cheap cable the charging was actually slower... even when I'm charging non-Sony devices ( like my Note 2 ) when I use original cable ( wether Samsung or Sony one ) charging is always faster... I don't know why it might be a way to protect the standard usb cable from over-current as the standard USB current is 500mA, so the charger will normally send the usual current unless the device requested higher current then it will negotiate with the charger to send higher current the original cables might have something like impedance between some pins so the phone will detect them as original then they will negotiate the charger to send higher current or the charger might actually use the other pins to send higher current but the phone will only use these pins when it detect the original cable... if not then it will not use these pins and will have regular 500mA charging... I've always faced this when dealing with other cables... now when I want longer cable I just use USB extension cable with the original cable and it will work !

- Yes, the cable can easily transfer more than 500mah. No worries.
- It means the docking station is rated for a maximum of 1800mah - so if you buy a 2100mah charger, the docking station may get warm and if it fails Sony won't cover it under warranty. If you use the 1500mah power plug, then the docking station supplies the 1500mah - it's just a pass-through. The docking station itself doesn't really have additional circuitry.

Can now make some docks/charging clips using sugru and a usb cable
Not sure why the dock would be rated at 1800, unless they've fitted it with some circuitry, a simple micro usb to prongs would do.
I charge mine using the adapter that came with my note tablet which is 2a and also with the 2a output of an external battery pack.

Yes, they're right to write the 1.8A there.
because, not all microUSB survive to deliver more than an amps. They maybe melt. especially the cheap one that have very small and loose contact area.
the pogo pins too... Not so easy deliver 1.8A with pogo pins...
that's why intel processor, have 1000+ pins, but almost 300pins are for power supply only (GND and VCC). Although the chip is only 1.25volts, but the current sometimes about a hundred amps (Core 2 Extreme, Core i7)

Wrong. If you connect a 2.1A supply, you'll see no difference.
Charging rate is set by the phone, as long as the power supply feeding it doesn't "brown out" under the load.
2.1A, 3.1A - doesn't matter, the phone will draw less (I'll need to drain my battery down a bit to determine how much less, it's often less than whatever the wall charger is rated.)
There is a possibility that when it sees voltage on the pogo pin connectors, it increases charge current to a different value than on AC via the USB port. The ext charger handling in the pm8921 driver is really convoluted and difficult to read.
so this combo is working for me:

http://www.amazon.com/gp/product/B00W98IQ5M?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00
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.

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 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.......
TurboPower charger that comes with it is the only thing that will give it a fast charge.
I have no idea how or why Quick Charge tech was left out.
Mine does indeed say "TurboPower Connected" and charges super-fast when I use the USB C Quick Charge 3.0 AUKEY Amp Type-C Dual-Port Wall Charger and the USB C Quick Charge 3.0 AUKEY Car Charger with Dual AiPower Ports. I can't seem to find it now, but I remember reading somewhere that the Moto Z does use QC 3.0, otherwise I wouldn't have bought the above products. NOTE: I am going USB-C to USB-C.
Does not use 3.0.

In short QC 2.0 and 3.0 don't follow usb c spec according to a top Google engineer. According to Usb c spec the vbus voltage should not exceed 5v. QC tech exceeds this by using 9v and 12v to achieve more power. Motorola built the Moto Z according to spec which allows you to ramp up the current (amps) to achieve more power which is why our stock charger outputs at 5.7amps. You don't need QC to charge fast with Usb c. Usb c with power delivery is actually better . Either way the QC chargers put out 15 watts total. Our turbo charger does 28.5 watts using 5v at 5.7 amps and is actually faster than what's out now. QC chargers use higher voltage to achieve this at 9v 1.7 amps 15 watts, a charger doing 5v 3a does the same 15 watts. So to turbo charge your phone don't use QC chargers unless it also outputs at least 5v at 3a that's the key. Anything less than 3a won't turbo charge. It needs to be a usb C to usb C cable so the charger should have a usb C port not a usb a port like most of you are trying to use. No other charger out now does more than 3amps besides the turbo charger until then use chargers that do 5v 3a. Verizon has a fast charger that supports this and all other fast charging tech.

I know these are not as nice as having some other 5V/5.7A charging options but at least they should charge better than QC 3.0 chargers.

Will these charge as fast as the stock charger out of the box? And with a USB C cable does it need to support quick charge, or do all USB C cables support quick charge as long as you have it plugged into a USB C quick charge adapter like you linked to?
Nothing charges as fast as the stock charger as far as I know.
I looked around on Amazon to try to find a spare charger with the same speed as the OEM, but there are none as far as I know. QC actually goes against usb-c standard, so whoever has a phone that supports both is technically being shorted on charge speed. I will be waiting for the verified brands (ex. Anker/Aukey) to release a legitimate charger because there have been instances where wall chargers have completely destroyed devices. For the fastest charge, you'll want usb-c cables end to end, but since usb-c is not the standard yet, I would be very careful when buying lesser-known usb-c accessories. Z owners will have to wait for the market to catch up at this point.
Total side note but I wonder if the problems Samsung is having is because of their bastardized quick charge/type setup.
I'm happy we don't have QC.

I bought the Choetech charger from amazon and it works great on my Z Force. no where near the OEM charger but still charges the phone dead to full in a little over an hour and a half. from my limited testing.

Ha! I was thinking the same when I heard about battery fire from the Note 7.
I just bought another oem charger from amazon and called it a day.

The car charger that Verizon sells turbo charges the phone, but not as quickly as the stock home charger. I don't think any charger will charge as fast as the stock home charger, since it's optimized for the phone. But the Verizon USB-C charger charges the phone plenty fast.

I can confirm this. I just got this phone on an upgrade after insisting to the Verizon sales representative that I did NOT want a Galaxy S8, that I was absolutely sure I didn't want the S8, and that I think the Z Force is a much better device than the S8. After seeing the genuine shock on his face that I slighted his phone, I bought the OtterBox case and the Verizon branded USB-C car charger with it.
The car charger definitely charges faster than my non quick charge USB-C cable, but not as fast as the stock charger. The stock charger will take me from ~5% to full in an hour. The Verizon car charger takes about an hour and twenty minutes to go from ~5% to full.
All in all, it was worth the money spent on the charger. It is definitely better than the 8 hour charge my standard USB-C usually takes.
