Seeing as all of my old chargers are for my SGS2 and put out a measly 0.7A compared to the 2A of the note 2 charger, I was wondering if I can use a different USB cable with the note 2 charger and still get the full 2A from it?
The reason I ask is the original USB cable that comes with it doesn't seem to be well thought out and has difficulty staying in if you move the phone about while charging.
Got the same issue. Tried galaxy Nexus cable. And it barely charged several percent.

Most cables should work. But it requires a good quality and moderately thick cable to provide close to 2A without a massive voltage drop.
You could try to shave a little of the excess plastic from the original SGN2 cable, so as to make the connector longer. My phone does not have a problem holding to the USB connector as is, but it seems quite a few other users have some trouble.
If you really need a new cable, try to avoid the cheapest ones. Also don't get one longer than what's needed.

I bought a 3m long cable. Works just as the regular. This cable is about as thick as the original. I would avoid the very thin cables when using the 2Amp charger.
Just a warning... If a cable does not fit, do not make it fit. Mine did not at first. Adjust the "hooks" on the contact by pushing them in slightly. There will be less force needed when connecting and it will still sit more tightly than the original.
Just buy a USB extension cable.
I'm using the original charger with the cable from my Kindle paper white and it seems to charge just fine. What's the advantage of using thicker cables?

I noticed that the Note 2 is a hungry beast. Have it for two days and tried to charge it on my Note 1 craddle with the Note 1 charger. Charged for 6 or so hours but was only at 57% when I took it of. You definitely have to use the 2A charger and mind the cables!
My Note 2 came from Handtec and was in French packaging, and the Samsung 2A charger was a 2 pin version but Handtec had supplied another charger with the UK 3 pins. This works fine but is only 1A and I've been using a range of other micro USB chargers and they all seem to be ok.

That's what I was wondering. I will buy and use one, then give feedback.
Okay, just tried a cheap extended usb cable and initially it showed charging but within a minute it wasn't charging anymore. Enough of cheap cable, now I'm gonna search about Belkin usb extension cable.

I don't think it's fair to say that, at least regarding the chargeing cable. Samsung uses a regular microUSB connector, just like all phones sold in the EU should. It's Apple that insists on proprietary connectors.
The Note II has a large capacity battery (good thing, right?) and Samsung decided to provide it with a power converter capable of chargeing the phone in a relatively short time. It requires a moderately good quality cable to allow a strong current to reach the phone within USB limits, but that's just physics. Not Samsung's fault.
(I do, however, blame sellers of very cheap cables. Buyers are the ones who suffer because the manufacturer decided to shave a cent or two from their costs.)
What I would recommend those that need a longer cable is to get an electrical extension instead.

Besides being physically stronger it can also have slightly thicker treads, allowing a bigger current, with less voltage drop until it reaches the phone. Orginal cable is 23AWG (power) and 30AWG (date). The thinner they get the more voltage drop, the longer they get the more voltage drop. The voltage drop is also affected by the material of the cables... The thickness of the cable may just be stronger shielding or better isolation, so look at the AWG markings and avoid too long cables.
My 3 meter, 24AWG (power) and 28AWG (data), error... sigh... AWG size is opposite towards milimeter... The lower AWG the thicker thread in the cable. The lowest AWG threads on the cable is for charging.

ElectroDroid can calculate voltage drops. I really need to little shorter cable

I've got saerm problem, the reason is that the micro usb tip ( the one you insert on the Note 2) is short. It can be easily solved by buying a different cable, or like what I did, I just filed the surrounding plastic to make the metal bit longer. It now latches perfectly with a click !!! Good luck

I have used both sgs2 and note 2 cables wt note2 charger both cales r propriety samsung i put my note 2 battery to 5% abd charged wt the note 2 charger
Both cables took 5 hrs to fully charge note 2
So i think if u use propriety samsung galaxy series cable it dosent matter
The i charged the phone wi sgs2 original charger
It took about 8 hrs to reach frm5% to 100%
So i think the output of the charger matters not the cable
I cant say the same about non propriety usb cables as i havent used those
I have a micromax a 7o usb cable which runs androud
I will use it wth the note 2 charger and post result

I did not say there would be extreme differences, but if you want a good quality cable... It does not say what AWG the SGS2 cable has (I find no markings), but the cable is a factor, but a small one, than can be noticeable especially if you have some length on the cable. If you use 1Amp on a 1.8 m 28AWG copper cable there is almost 16% voltage drop. If you double the current you also double the voltage drop. That does not mean that the charging time will be changed much in some cases since there are other factors that affect it too (internal electronics that handles the charging, battery health, the real charge Voltage/Current at the battery leads....).
I just got a high quality cable from Manhattan Products and their website says:
http://manhattan-products.com/en-US/products/9204-hi-speed-usb-device-cable
28 AWG conductors
Shielded
Withstanding voltage: 300 V DC 10 ms

Contact resistance: 10 OhmsThermal plastic casing.
What's the AWG of the original cable? Is my cable's awg for the data or current?
Sent from my GT-N7100 using Tapatalk 2
Orginal is 23AWG power and 30AWG data. You can read it the cable actually. You even see that it has dual commons.
If it has dual sizes the bigger size is power (bigger is strangely enough a lower AWG). If it only mentioned one size then it is used both for data and power.

So, I have powerbank and I have 2 ways of charging: 1A and 2.1A. which one to use when charging my note 2?
Handwritten from my Note 2
Depends on the cable you'd use. Samsung cable will go near 2amp, generic ones do about 1 amp

I have samsung cable.. So is it smart to charge via 2.1 A ? Can it do some damage on the phone ?
I have a Momax external battery and have charged the phone with the 2.1A port. It didn't heat up, it didn't have any problems. I was planning on measuring the exact amperage that comes out of the samsung charger and the momax battery (iPower Pro), but I didn't get around to it, because I suspect the difference is actually smaller. There are many people who used more powerful chargers to charge their phones faster, and the only thing that degraded was the battery lifespan, but the difference in those cases was upwards of 0.5A between the original and the new charger. I find the 0.1A to be a small difference and I have no problem using the 2.1A port on the iPower.
So to answer your question, no, it won't damage your phone. Theoretically it damages your phone's battery, but it degrades anyway due to charging cycles, so you won't notice any damage caused by the extra 0.1A unless you plan on still using the note 2 10 years from now.

Thanks for reply mate ! I was thinking the same, but i needed some sort of confirmation tho
Use the 2.1A one.
The phone should only draw 2A from it anyway, that just means the port is capable of supplying 2.1A.
Using the 1A port will just charge your phone slowly, the 2.1A port should charge it as quick as the official charger, depending on which cable you use.
It is a matter of supply and demand. All USB devices can safely be plugged into any USB charger. Given an unlimited amount of current available from the charger, each device will still only draw only as much current as it is designed to draw. If the charger is rated 2.1 Amps or 5 Amps or 10 Amps, a 1.5 Amp device will still only draw 1.5 Amps. The charge rate will be at maximum Think of it like your house wiring. The circuit may have a 20 Amp circuit breaker in the basement but we plug in 40 Watt bulbs and 100 Watt bulbs and TVs and electric shavers that all draw different amounts of current. The 100 Watt bulb uses less than an amp but is unharmed being plugged into a 20 Amp receptacle (charger). Now we come to the flip side. If the charger Is rated lower than the device it just charges slower than it would if the charger could supply at least as much as the device uses. To go back to our example, the 1.5 Amp device plugged into a 1 Amp charger will take longer to charge that it would with a charger rated 1.5 Amps or higher. My analogy has one hole. If the stuff plugged into the house receptacles exceeds 20 Amps the circuit breaker pops. This will not happen with USB chargers as they limit the current and will not try to supply more than they are rated for. Stick to chargers rated as high as the one that came with your device or higher and you will be fine
I have been having trouble recently with my galaxy s3 charging extremely slowly. Every since the OEM cable broke, I have tried to find replacements that charge at 1amp. The only cable that does this is the monoprice premium micro usb cable 6ft, but it breaks quite easily. I have also tried the 28awg 6ft monoprice cables, which were pathetic and charged at 100ma. This was all plugged into the OEM 1a wall charger fyi.
I have heard that the 24awg cables with ferrite core charges at a full 1 amp because the cables are thicker, but what I don't understand is that the OEM and premium monoprice cables both charge at 1100mah but are really thin compared to even the 28awg cable. The OEM and monoprice cables don't have specifications printed on them. I had always thought that generic usb cables were the same as OEM cables, and would charge at the same speed, unless there's something wrong with my micro usb port or phone.
I have tried looking for solutions but the answers on most forums are people asking why their phone charges slow when it is plugged into a usb port, and everyone just replies that the usb port output is limited to 500mah, but I am using the oem ac adapter and it's still slow. Only the premium monoprice cable charges full speed but its very poor in quality, the rubber cable separates from the plastic micro usb head, and it breaks. I have had 3 of these premium cables break in less than a weak and only 1 of them works, for now.
Is it my phone's micro usb port? I tried charging it using CM10.1 as well as Touchwiz 4.1.2, but they all charge slowly from the generic cables so it can't be the rom. I don't remember having any of these problems when I first bought the phone on ICS, and I don't see many posts on slow charging.
Is there a cheap, reliable cable that charges at a full 1 amp out there? Most people I've seen had suggested monoprice cables but their 6 foot micro usb cables have changed recently and are really, really bad. I guess the ferrite core cable might work, but I have yet to try it, and I am not fond of the idea of a thick 24awg cable and a big ferrite core sticking out of my phone.
First of all, do you have Galaxy Charging current app? https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free - I think it's free for N2 and S4, but you have to pay $0.99 for S3 (I use it for free on my N2, but a buddy of mine had to pay to use it on his S3). That app will give you an idea of what's going on. You can also check out Charging Doctor I reviewed here: http://forum.xda-developers.com/showthread.php?t=2451375
Second, charging speed is a combination of both a charger and a cable. The only way to guarantee full 1A/2A output without high resistance which contributes to a drop of charging speed is to use thick wired cables like 24AWG as you correctly pointed out. But with wall chargers - just because they state 1A you will NOT actually get 1A due to efficiency losses. You know how your charger gets warm? That due to AC/DC conversion inefficiency which results in drop of speed and release of energy in a form of a heat. I personally don't trust labels on cheap chargers and also over the time even an efficiency of a trusted converter will go down. I have reviewed a lot of Anker batteries and chargers (check out review link in my signature), and those are the one I highly recommend.
What I would recommend getting one of these trusted 2A chargers and use 24AWG cable and check it with Charging Current app. If you are still seeing a very slow charging speed it means your micro usb connector is wearing off or loosing a contact with a main printed wiring board (pwb) inside of the phone.
Does anyone know of a charging cable that will deliver a solid 1, 1.5 or 2 Amps?
I ordered a few cables off of Ebay and when I started using them I noticed that my phone wouldn't charge at all (or would charge at a rate of 1% every 8 minutes) when I started using it. I then bought a USB in-line voltage tester to test my outlets and cords, since I couldn't really make contact with a multi-meter. I found that using the Ebay cables I wasn't getting any more than 300 mA! Using the official Samsung charger and cable I was able to get 715 mA and the highest that I got out of the 6 outlets I tested in my house was only 878 mA. The Samsung charger is rated for 2 Amps and I know the phone will only pull as much as it needs but I'd expect it at least pull 1 Amp. I also used an Asus 2 Amp charger,an HTC 1 Amp charger, and a 2 Amp USB wall outlet along with the charging cable that came with my Logitech Performance MX mouse.

I know people have asked this before and I saw someone recommend Monoprice, so I found these 28 gauge and 24/28 gauge , but does anyone know of a vendor that sells 18, 20, or 22 gauge charging cables?
Edit:
After some searching I found 18 gauge 5 Pin Micro USB cables from Alibaba...but I'd have to buy 1,000 of them :-/ The smallest I could find in small quantities is 22 AWG from NewEgg
18 gauge would be ideal because it could deliver a max of 2.3 Amps. 20 gauge would deliver a max of 1.5 Amps, and 22 gauge would deliver a max of 920 Miliamps. Here's a chart about wire sizes.

There is no such thing as a heavy duty charging cable for cell phones.
The charging rate has nothing to do with the cable itself but it has all
to do with the charger. Stock charger delivers about 2 amps & using
the computer as a charger only gives you approx 1 amps.
The gauge of the wire/cable does not make one bit of difference since
we are talking super low voltage (3.7 volts).
So at 2 amps at 3.7 volts it would make no difference if the wire
was 18,20,22 or 50 gauge at these very low voltages.
If the cell phone was charged at a higher rate than 2 amps like
3-4 amps it would degrade the battery since it would constantly
be over heating and thus would have a much shorter life span.
The battery could get so hot that it might even explode!
Good luck!
Well how do you explain the variances in Amps when using the cheap Ebay cables compared to the Samsung/Logitech cables?

I can say the cable itself does effect charge rate. Some are charge and sync some charge only cable. Adapters are different thing. I have a oem samsung cable that charges pretty slow compare to a cable i got from gamestop .which charges somewhat 25% faster. And some ebay cables which drains while i play with my phone and charges 15 % per hour. Test both into wall socket and computer usb. The gamestop.white cable charges faster both ways. Same result when plug into my car usb port. Not the 12v plugin port

The amps/milliamps output will always vary depending on the battery condition
at the time it's being measured.
A battery which is close to being fully charged will charge at a rate much less
than if the battery had very little charge left in it.
That's how most any charger works, there are no chargers which will put out
2 continuous amps regardless of the condition of the battery.
When we are talking about milliamps output from our computers or from any of the cell phone
chargers the rating of 2.0 or 1.0 or .5 milliamps are only in the specs to let us know the maximum
milliamp rate that any chargers can charge. (up to 2mA and so on, depending on battery condition)
Good luck!

You are right, there are two kinds of usb cables for cell phones, one only charges
and the other is for both charging and data/sync.
However the only difference in the two types of cables is that the the charging
only cable has one less wire connected to both ends of usb cable connectors.
The two wires which actually charge are the same in both kinds of cables.
(common ground and 3.7 volts)
It takes only 2 wires in the usb cable for charging while the data/sync and charging
cable needs 3, one for common ground, one for 3.7 volts and one for data/sync.
But as far as different brands of usb cables charging more or less that's just not true.
Just think, if what what you are saying is true then that would mean that if we plugged
a 50 watt lamp into a heavy duty extension cord it would make the 50 watt light bulb
brighter than if the extension cord was a 99 cent cheap import. LOL
I talked with my father, who has been an electrician for about 40 years, regarding this and he pretty much said the same thing. I remember seeing on the external Samsung battery charger that I have said it charges at a rate of 700mAH, so I guess the same goes for charging it in the phone within a slight tolerance.
The only concern on charging cable is the resistance. Chop some cheap eBay cables in half - you will be hard pressed to find the copper. If you lose two volts from one end of the cable to the other - you will not charge fast. Also some cables are not wired correctly for high speed charging.

Perhaps you missed the part of the statement which referred to "copper." Some imitations using other conductive materials have resistivity as much as 30 times that of copper.

you may please understand if the charger have 2 amp , phone is capable to take 1.5 amp but the cable .....
in this condition if the cable is not good one the phone will not get the correct amp but it will give the correct volt you can check your self
like this drain the phone to 10% put it in to off condition then charge it with a 2 amp charger with good cable (Samsung 2 amp charger cable or original charger cable of Htc ) switch on and check after 10 minute do this with cheep china made cable then you will get the result :silly:

You are responding to a 5 month old post.
Opinions are often spoken as facts on the Internet.
The quality of the cable has a drastic affect on the charge rate. I can prove it with Screenshots if any of you would like.
Verify the charge rate using this app - https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free
While travelling in the Philippines and Thailand I found very VERY many fake Samsung chargers and fake Samsung cables that could only output low MA during the charge cycle. Since then I've been searching for inexpensive cables and chargers that can run at the full 1900ma as indicated by the above mentioned app.
Very true. They can also trash a battery. Our OE charger has a chip (I think its really a resistor) that aids the phone in controlling the current. It provides a steady current to the phone, then the phone lowers it to something within the batteries specs. Then again, the battery itself has a resistor also. Its all meant to give a steady current at the right voltage/amps. What comes out of your electrical outlets and car charger ports isn't steady.
This is where a "good" charger comes in. A crap one will not level the current and it'll fluctuate constantly. This causes bad/dead cells, swelling, overheating, ruptures, or even fires and explosions.
Sometimes even using a charger meant for another phone will mess things up. It won't hurt the battery usually but it'll cause random reboots and the real vs assumed charge will be way off. There's a lot more that goes on when charging these phones than simple + and - terminals moving electrons between an anode and cathode.

Seeing a stupid comment on Google Play about an app you love and marking it as "spam". You've done it too.

First, the cable makes a HUGE difference. Get " current widget " from play store. I use "portapow" cables from amazon. From the same charger, I get 1.3 milliamps from portapow cables, and .75 milliamps from stock data/charging cables. You will never get the full 2 amps from stock charger. But I swear by these cables.

so I baught a few USB cables from eBay and dealextreme and they charge the phone super slow.
battery widget shows they charge at about 50, compared to my retail that charges super fast at 1000
where do i get GOOD cables?
A few years ago I bought a couple of blackberry OEM cables on Amazon, and ever since, those have been my favorite ones because they are really nice high quality cables. Recently, I was looking to buy some more, and I bought a pack of 5 for $10 from the ebay listing below. I can vouch that they are the same genuine blackberry cables I've received in the past.

I don't think its the USB that slows down the charging. It's the charger? I bought plenty of cheap USB and all charge at same speeds using the stock wall charger..
first of all, thank you!
2nd lol @28usd shipping to Israel
/=
but should i be just looking for OEM cables?

Yes, I would look for genuine OEM cables from a name brand. However, with ebay or other sites that have 3rd party sellers, they will often say OEM when in fact they are knock offs. It is more common with chargers than cables. I felt comfortable with that ebay listing because it looked like an actual picture of the product and not a stock image. Also, I already owned a couple, so I knew what they looked like with the blackberry logo on the end.
USB cables plays a big part. out of my 10 USB cables that i own only 2 can manage to transfer 1A.

Fosmon Vivid Series Flat Tangle Free Micro USB Cable for Smartphones and Other Micro USB Devices (6 Feet, Blue) by Fosmon Technology http://www.amazon.com/dp/B00E0M55RC/ref=cm_sw_r_udp_awd_she1sb0525RFD
Comes in a variety of colors. Looks like as of this writing, only the 6ft length is prime eligible. 3ft length has a $2.98USD shipping cost.
I use these all over, have bought many and all are still working great. I use them with a 2A anker charger. Charges my phone very quickly.
Good luck

I pretty much buy all of my cables of any kind from Monoprice.
I just posted a thread about this yesterday.
http://forum.xda-developers.com/showthread.php?t=2608236
It's also got a $10 off $30 deal as well. Make sure to choose the Premium Micro USB cable, as the normal one is not guaranteed to charge quickly.

Yeah I purchased initially because I wanted a flat cable. These really are tangle free and they are tough as nails. I bunch them up, roll them up, tug/pull etc and have yet to have one fall apart or crap out functionally.
Biggest problem I have with it is my coworkers stealing it from my desk!

What's the mA charge rate when you use it with your 2A anker charger? Does it allow fast charge (Full 1050mA)?

sorry, I do not know how to test that...?
I am using it with these chargers:
Anker® 18W/3.6A Dual-Port USB Wall Charger / Portable Travel Charge... http://www.amazon.com/dp/B00B8L36A6/ref=cm_sw_r_udp_awd_SVf1sb1DQ2N3K
Anker® USB 24W / 4.8A Dual-Port Car Charger - Simultaneous, full-speed charging(White) by Anker http://www.amazon.com/dp/B00B8M4IMK/ref=cm_sw_r_udp_awd_GXf1sb07XQGKT
It definitely charges substantially faster than the OEM wall charger for my Nexus 5. That may be the charger or cable or both.
Would be happy to test the mA charge rate but I assume I would need an ammeter which I do not have.

If you could test that would be great! I just ordered a bunch of high quality full speed micro USB cables from monoprice that I linked above, but I wouldn't mind having some more that were a little more fun and colorful. It's always nice to change things up every now and again.
You don't need a multimeter or anything.
Just get CurrentWidget off of the play store (it's free) and add a widget to your homescreen. Set the update interval to 1 second, and watch for the highest number to repeat multiple times (it will always fluctuate up and down, but the highest number will keep popping up) that's your max. It may take a few minutes to get to the top speed, but you'll know when the same number range keeps showing.
It's probably not 100% accurate, but it gives a good ballpark number. The stock LG charger/cable charges at ~1050mA. If the flat cables allow full speed charging, you should be able to match that.

Installed CurrentWidget and ran the tests - very sad to see these fosmon cables that I love so much are limiting my rate of charge.
I tested the Anker wall charger with both the 3ft and 6ft fosmon cables at work and got a max value of 480mA. At home I got a max value of 518mA
I tested the Anker car charger with both cables and was floating around 350mA
When I got home I compared (using the same outlet) the Anker wall charger versus a Blackberry Charger I have (which is the fastest charger I own) and found a distinct difference. As stated before the Anker wall charger with both lengths of fosmon cable maxed at 518mA. The blackberry charger maxed at 1589mA.
FWIW, here is the blackberry charger I used (no, the cable is not detachable from the wall adapter)

Sorry to hear about the cables, I was going to grab a few if your results were different. And sorry about making you sad bud... I guess you can see that it's not just a high amp adapter/charger that is important, but the USB cable has to support high charge rate as well.
Your Anker wall/car chargers are very good though, if you used different cables (or even the stock Nexus 5 cable), the charge rate would be faster.
I've heard of the Blackberry charger being very good, but to get it in Canada (amazon.com won't ship it here) I have to use amazon.ca and they charge $20+ for it... Which is so stupid considering Blackberry is a Canadian company located in Ontario... You'd think it'd be a bit cheaper in the motherland.
But it's not really necessary for me anyway, I'm making an attempt to have all of my chargers as Qi chargers. I have plenty of 2A adapters, I just wanted really good USB cables to make sure my Qi chargers are getting fully juiced so they can provide the full 1A output.

No worries - if anything I thank you for showing me how to test it. I had read a review on these fosmon cables saying they were fast current but never went so far as to test (because I thought I needed an ammeter to do it).
These cables still have their use, but I will be snagging a few of those ones linked on monoprice for my bedside, work and car chargers.
I am going to look more at fosmon too (maybe reach out with an email) and see if they offer or plan to offer a flat micro USB with more amperage.
Side note: which Qi charger are you using? Specifically using well with those cables from monoprice.
