I got an aftermarket charger in my area since original ones were not available. It says on the label though it's for Galaxy Tab but the max amp is 2100mA min 150mA and the usual 5volts. Is it safe to use even if the original one says 2000A?

Yes,where did u get it,I need one
Just some cell phone shop in my area. My original question was I was asking if it's safe to use even if it has higher amps.

technically, its ok to charge at a higher amperage, it would just entail that you would be able to charge it faster.
but there might be a risk of overheating the battery during charging and that might lead to problems in the long run.
on the other hand, 100mA wouldn't be much of a difference.
It will be perfectly fine. The units charging circuitry will only use as much current it requires, heck you could charge it from a 10Amp 5volt supply with no troubles. I have used in the past an old pc power supply rigged up to some usb sockets to charge various usb devices without any trouble. They are capable of supplying upwards of 20amp @ 5volt.
Btw, i am a qualified electronics technician of 12years experience, i have experimented a LOT.
@baskarz thanks for clearing everything up baskarz.
@prinzhernan could you post a pic of what the charger looks like? thanks

2A chargers will work with the SGT, but you need an adapter like these that I bought.
http://cgi.ebay.com/USB-car-wall-ch...ccessories&hash=item2c5c07736b#ht_3085wt_1163
Reason is the ones that says "For Galaxy Tab" chargers have resistors soldered to the usb port allowing the SGT to know it's connected to an AC adapter and to pull the full amount of power it needs. The adapters have the resistors in them allowing u to use any cheap charger. It allows you to charge with a standard computer/laptop usb port as well. I think it's supposed to charge faster than the trickle charge you get without the adapter but I have yet to try it out. There's another thread that goes into way more detail about it and even how to solder your own resisters to make your own adapters. Think it was this one: http://forum.xda-developers.com/showthread.php?t=845844&highlight=usb+charge
you can charge anywhere were there is a USB port. Just make this.
http://forum.xda-developers.com/showthread.php?t=845844&page=3
that tells your galaxy tab to DRAW POWER from the USB port thinking it is the supplied CHARGER. you can use ANY USB port or charger with this.

Hi Ricey
Correcto, my post can help anyone who wants a 2nd charger to be permanent in office or etc
And most importantly not buy the regular 2A without the resistors inside.
Awesome. Sounds great.
Hi,
Getting an EU version of the Note, so I need to buy a Uk charger, is the charger for the Note and Galaxy S2 compatible? Thinking buying a 3rd party Galaxy S2 charger on ebay.
Many thanks
I suspect any 5v microusb charger delivering over 0.5A will be fine.
Expansys sent me a standard HTC one (5v 1A) with my german note and I am in the UK.
Thanks, I have a couple of generic USB wall chargers at home, so might as will use them with the Note.
I can't answer the question directly, but that big screen, fast processor and larger battery are going to take a bit more juice than your average phone, including the S2. When it comes to mains chargers that may not be a big deal, unless you leave the phone active while charging, but might become an important consideration if trying to use the phone for satnav in the car, for example.
At the moment I'm using an Orange San Francisco. That has a 3.5" OLED screen and a 600MHz single core processor, so hardly an energy guzzler. The supplied charger is rated at .7A. In the car, when using satnav, my generic USB car charger cannot quite keep pace with the energy demands of that little phone and the battery level actually drops slowly while connected to power in the car. I'm definitely going to be looking for something more robust for the Note.
Note charger is 1 amp, Nexus S .7 amp, Note charges fine off the .7 amp charger.
I assume a standard Samsung GS charger would do, the output on it is 0.7A?

You not only need a charger that can deliver more oomph, but also a lead or charger, possibly modified, that will allow the phone to draw that current. I have 1A USB chargers for the car but a regular data/charging lead only permits the phone to charge at the standard USB maximum current of 0.5A. I had to open up one of my chargers and solder the two centre pins together. Shorting those two pins signals to the phone that it can draw the full "mains" current rather than the 0.5A USB maximum.
I haven't yet charged the Note in the car, but on my previous phone the charging status would show "Charging (USB)" prior to the mod and once modded it would show "charging (AC)", which is what you need to keep the phone charged and charging while in use rather than slowly depleting.

I can confirm that SGS2 charger works on note. However charging is slow ( its 0.7 A )
However the note charger ( 1.0 A) charges faster
dont have a 2 A charger to test but I would say that it would be the same speed as 1 A charger.
If we want faster charging, we will need the kernel to modified.
The downside would be shorter battery life.

Would it work to get an adapter from the European plug that comes with the note to US outlet?

Thing is would the USB cable that comes with the note (designed for computers) be suitable in carrying 1000mAh?
I heard that USB cables that come with phones are 0.5mAh so it won't make use of the 1000mAh...
Can anyone confirm this? If so then it's better to buy an out and out 1000mAh plus wall charger or a worldwide travel adapter.

yes it will work fine, because the charger accepts 100-220vac 50/60Hz
The Samsung power adaptor that comes with the Note is a Universal one (110 Volts - 240 Volts) and is rated at 5 Volts 1 Amp output.
If you need an alternative for some reason (or a spare).........
Personally, I am using a generic iPad mains adaptor with dual USB sockets. The device was made in China and has a total current output of up to 2 Amps. It is a also a worldwide model. I think it charges faster than the Samsung charger.
It also charges the Note when using the MHL>HDMI output. I have read some postings that the Note very slowly loses charge when the MHL>HDMI adaptor (which has to be externally powered) is in use. With this 2A adaptor, it continues to charge.
You could also try the Genuine iPad adaptor that also works worldwide and delivers a genuine 1 Amp rather than some of the cheapie models that struggle to supply that current.
I'm about to use a Moto Milestone 1 charger for OB but I'm afraid that it may harm the phone. Both phones are listed with MicroUSB 2. Any tips?
thanks
Don't worry.. it will work Ok, but OB charger has 1000ma, if you use another charger that has let's say 500ma (like USB) it will take 3 hours to charge the phone instead of the regular 45 minutes!
I use a samsung cable directly from USB, the car USB port, a samsung 5530 charger, a LG optimus one charger, and they all worked, with various degrees of effectiveness!
The most useful one is the car's USB port that, even if it cannot keep up with the GPS (it charges slower than the battery drains), it can keep the phone running with 10% loss every hour with screen activated and GPS at the same time! The problem is that I hate radio and don't use CD's that much, and usually end up with the phone depleted before I reach the destination!
Thanks man! Ok I'll check that "ma" thing. BTW is it written on the battery or charger?

Both places; battery specify working and standby V and mA, charger specify the V and mA provider
So you can use almost every different charger if the specs are the same, but be aware of this: don't use a charger with less mA since it can burn the charger
Ma - miliamps.
How many milliamps in 1 watt/volt? The answer is 1000.
I assume you are converting between milliampere and watt/volt.
I never had a burnt charger by the way, that would be very strange considering that the phone is accepting 500ma from the start (that is the USB output on any PC), and I even saw chargers with a power of 2W (SUPER FAST CHARGERS). The Motorola chargers are 850 ma usually, so it should work quite good!
Indeed, it's very strange to have a burnt charger and we don't need to go into an electrical discussion but that happens because of 2 possible things, very high-peak of voltage or prolonged use of under-voltage

Thanks. Printed on my Moto charger is 850mA so I'll rather use it for my OB next time.
BTW, currently I'm using a replacement charger for my OB with a name "super charger" printed "4.5v - 9.5v 800ma"
It's charging at normal duration in fact I'm using it for days. The only problem is that my OB touchscreen freaks out if I use it while that charger is connected. It's obvious when I run the multitouch testing app because touch points run all over the place. Touchscreen goes back to normal if I disconnect the charger. I tested that "super charger" to my milestone and the same abnormal thing happens to the screen. What causes it?
Probably it's something to do with high voltage... I'd avoid using it if something like that happens to my phone..
Usually the USB style chargers are pretty standard... the speed with which they work are strongly related to the power (Amperes) they provide, the voltage "should" be pretty standard!

Battery experts say to try and use a charger that's rated half the power of the battery.
So for a 1500 mAh battery, a charger of 850 mAh should be a better option than a 1000 mAh one.
Yes, the 1000 mAh charger would charge the battery faster than the 850 mAh one but it will decrease the lifetime of the battery faster.
Just for be able to post new thread. Sorry.
Hello, I don't want to start a new thread so I'll ask here.
The charger that came with my OB seems to be damaged. It was working properly until last last night. My phone detects the charger but it won't charge. Got powermax turned on and it automatically turned off when I connected the charger, so I know my charger does have issues.
Tried banging the charger last night, connected it to phone and started charging, woke up to see that it stopped charging 2 hours ago. It didn't even fully charge my phone. Now I'm charging it with my pc via the USB cable. I noticed that the touch screen goes wild when I use it while connected with the USB.
Now, I'm planning to buy a Galaxy S2 charger. Is it safe to use? S2 and OB has almost the same battery capacity so I'm considering it. Any other suggestions? OB ain't popular here in the Philippines so finding accessories is a real pain in the a**.
Fitted a Corby 2 charger and it seems like they use Mini-usb too. Haven't tried charging with it though.
My original charger also died... Now I use the one that came with my bluetooth headset
So I guess using the OB charger on other stuff is okay too. USB is always ~5v.
You need to test the charger with something else to be sure, though.
I had the same touchscreen freaking out problem with my old LG KS20, whenever I charged it. Like it was shorted or something. So it maybe a problem with the phone itself.

Ok kabayan, don't forget to share here the result after u try gs2 charger. I too am looking for safe alternative to my milestone charger.
Standard port - standard voltage
Don't even bother, if it has a micro USB it should be fallowing the same standard as USB for charging (5V)...
Of course test the charger for any adverse side effects like screen flickering or short battery life, and don't use it if something like that occurs, but because of the standardized voltage and the fact that usually phone chargers have between 500 - 1000 mA, 99% of chargers work...
I still haven't found any incompatible charger for my phone and I don't even buy a phone if it has a non standard Charging/Data Port... it's just stupid... so no Iphone for me!

Hello guys! I'm here for an update. For the past week I've been using a Corby 2 charger. And guess what, it works just fine! only downside is it won't charge it up to 100% (usually gets to 99% upon unplugging). And it charges the phone a little slower than the original charger. I always let the phone overcharge overnight to have 100% battery.

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.

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.
Sent from my GT-N7100 using xda app-developers app
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.
Hi guys!
I recently switched from a Samsung galaxy s5 to a nexus 6. It's been more than great, really. Why did I ever buy galaxy phones?!
I'm confused over quick charge 2.0 and compatibility with other chargers and couldn't find any proper information on the subject.
At the moment I own:
- Aukey 5-port 35W Charger
- Tecknet 6-port 50W Charger
- Anker Astro E5 15000mAh battery bank with 2A + 1A ports
- Large assortment of other single port chargers @ 2-2.4A from Samsung, ASUS, and several aftermarket brands.
All of these chargers, and the battery, delivered (tested with the Ampere app and tons of different cables) ~2A to the galaxy but only deliver ~1A to the nexus 6. The Motorola turbo charger obviously works as intended. Now my questions:
- Does quick charge 2.0 limit any non compatible chargers to 1 amp?
- Is there a way to mod chargers to at least get back 2A charging?
- Worst case, does anyone have experience with a recommendable battery bank and multi port chargers that support quick charge 2.0?
Thanks!

Why would you need options relating to change charge speeds? Qualcomm quick charger works on any kernel, if you're talking about USB fast charging, it's already enabled in Franco kernel.
There isn't a need to switch to other kernels.

Laptop USB ports at limited to 500mah output unless its a dedicated charging port with USB 3.0 then It can push 1.6A so I don't see how that's possible to charge at 2A from a laptop.
@Pilz this is irrelevant. My 2014 macbook pro charges my old phone much faster than the nexus 6.
Refer to the original post for the topic at hand
Quickcharge 2.0 devices uses the data pin on usb to determine if the charger connected is a quickcharge 2.0 charger. The devices you are using do not have this capability so they charge slower. I do not think this can be changed kernel or phone side.
Thanks! I guess I'll have to replace the chargers/battery

Nothing wrong with the turbo charger

I could be wrong S5 I looked up uses usb3.0 right? Does your macbook have usb3.0? If so then the usb 3.0 port can supply more current when detected being a usb3.0 device by your computer and ever more so it is possible for the mac to output a little more current. Can you plug in the S5 then open system profiler to look at USB device tree to see current being delivered? The nexus 6 only using usb2.0 would not get the same treatment by the comp and only receive the max standard of .5 A.
There are many details about the actual max current that can be supplied by the computer's ubs port that I don't know when they are applicable I've just stated reading so I'm not sure why you can get 2.0 A on your S5 and not less, since there are standards that set the max current. Even more complicated is that under certain conditions macs have their own heirarchy of supplying more current to some devices if they "say they need" more current and even then there are limitations. So again I'm not sure what is at play exactly, that determines why the S5 gets more than usual. The .5A is normal for current output on USB 2.0 in the nexus6.
I actually got this in the mail yesterday, and the wall chargers works great...Havent have a chance to test out the car one though!

@Pilz this is irrelevant. My 2014 macbook pro charges my old phone much faster than the nexus 6.

That doesn't make sense which is why I went into some detail about laptop or any computers USB ports. I unfortunately had a MB Pro and hated it, and it never charged any of my phone a at 2A including my wife's old S5. I don't have it anymore so I can't test it again to verify. The person I quoted below explained it a little better than I did.

Getwow is officially certified? Why, because they're Amazon page says so?

Those lying bastids! They even stamped Qualcomm 2.0 right on the side lol . Regardless..Wall chargers works as does the car charger, same as the Motorola one

Qualcomm doesn't post every certified charger on their website. In would email the manufacturer and ask for their certification or a picture of it which most will show you assuming on they're legit.

Hi guys!
I recently switched from a Samsung galaxy s5 to a nexus 6. It's been more than great, really. Why did I ever buy galaxy phones?!
I'm confused over quick charge 2.0 and compatibility with other chargers and couldn't find any proper information on the subject.
At the moment I own:
- Aukey 5-port 35W Charger
- Tecknet 6-port 50W Charger
- Anker Astro E5 15000mAh battery bank with 2A + 1A ports
- Large assortment of other single port chargers @ 2-2.4A from Samsung, ASUS, and several aftermarket brands.
All of these chargers, and the battery, delivered (tested with the Ampere app and tons of different cables) ~2A to the galaxy but only deliver ~1A to the nexus 6. The Motorola turbo charger obviously works as intended. Now my questions:
- Does quick charge 2.0 limit any non compatible chargers to 1 amp?
- Is there a way to mod chargers to at least get back 2A charging?
- Worst case, does anyone have experience with a recommendable battery bank and multi port chargers that support quick charge 2.0?
Thanks!

It is technically incorrect for the phone to accept more than 1 amp on a 5v charger. The quick charge *protocol* negotiates a non-standard charge voltage (up to 12 volts!!!). Quick charge is actually BAD FOR YOUR BATTERY! The higher the current, the greater the temperature. The greater the temperature, the lower the battery life.
Unless you *need* it to charge that fast in an emergency, don't.
I've never even plugged in the charger that came with mine, and I don't intend to.

I've used QC 2.0 since I bought my phone during long days and my battery life is just fine. My battery is cooler during QC than when using qi charging so I disagree. Generally speaking you're correct, however the battery would need to get hot and stay hot which is doesn't. QC 2.0 tapers off the voltage and current overtime to a more "normal" amount. Your argument is an old and doesn't always pertain unless your phone is constantly hot.
You're battery degrades overtime anyway and any heat could speed that up. I used to live in AZ where it gets to 120+[°F] in the summer which is hotter than my battery ever gets even using QC from 1% battery. Quick charging won't hurt your battery any more than normally charging it will. There is a cut off for the temperature it will let your battery get before it drops voltage or amperage which will work whether the what is from charging or the environment you are in. As I stated above qi charging will make your battery heat up more (in my case it does) I will post screenshots to back that up if you would like.
Lastly no one is expecting a battery to last 1-2 years without losing capacity so why worry about it? Your phone is warrantied for at least 1 year (I have moto care on top of the regular warranty) which will cover any battery issues. There's no need to panic or make an issue out of nothing.
Now can we please let this argument die? I keep seeing it and its getting rather old. Even if it does (which I'm not saying it does) degrade slightly faster its not a big deal for the aforementioned reasons. Let's get back on topic here people
