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.
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.
I've managed to find some chargers (both car and wall) that will charge with 1800mA (according to Galaxy Charging Lite app).
I have not managed to find an aftermarket cable that will charge at more than 1amp. Anyone know of an aftermarket cable that actually is capable of 1800mA? I've tried nGear and monoprice, and while they are very well constructed cables, they will only charge at 1amp or less with the n7100
Thanks for the help in advance, but please only respond to this if you've actually tested the cable with with the Galaxy Charging app or a current meter of some sort. I'm not interested in cables that only work anecdotally.

I'm breaking your rules (gasp) but as far as I'm aware, it's not the cable that manages the charge, it's the power adapter that feeds the usb, right? I've used all sorts of random cables on my travels for work, but always sticking to my 2+ amp output charger, and they've always worked.

Find a very short cable and you'll see rates up to 2100 ma (as measure by battery monitor widget). I use the short usb cable that came with my jambox combined with the the phones stock charger. The charger gets so hot due to the high current that I worry if it might burn out. The cable is very short, like 6 inches. I use this one when i need a quick bump before going out.
At this low of voltage plus high current, the shielding on most cables is not enough to protect against the voltage fluctuations caused by the high magnetic field. The longer the cable the more shielding is needed. Additionally, the cable shielding gets less effective as the cable gets older due to general wear. My original usb cable can only due around 740 - 1250ma, where it used to do 1800ma when new nearly 2 years ago.
If you could find a cable where there the positive and negative wires are separated in parallel strands like traditional AC power cords, it would also help. I have a cheap charger with built in cord like this and it charges consistently fast.

Most USB cables will work with the charger, but some cables (usually longer or smaller gauge wires) will restrict the charge to a lower amperage. I still haven't quite figured out how the phone knows what cable is being used, because, realistically, in a simple DC circuit, the consequence of using a cable that is too small is heating up or burning out. A cable that is too small alone will not prevent too much amperage from going through itself. This is why they invented fuses. Somehow the phone detects the gauge/length of cable being used and restricts the amperage being pulled from the charger by changing its own resistance on the circuit.

I suspect you're right. The impedance of a cable is the only thing that would change over a period of time that would result in a cable that could once pull 2A to start pulling less than that. Still, it would be nice to have a list of chargers/cables that consistently pull 2A before dropping $15-$30 on one of them. There exists such a list on this forum, but it is filled with comments like "It's good enough for me", without any real data as to what performance they are getting. Hence my rules above.
The charge rate depends on your kernal not the cable. I use Agni and get over 2 amp charges from a USB cable I paid 12 cents shipped for on eBay.
I purchased this cable about two weeks ago and it delivers!! I can charge my 9300mah Zero Lemon battery from 0-100 in just under 4 hours. Stock battery in about 1.5-2hrs. Of course I'm using a 2.1 amp charger, but NONE of my other cables come close. I'm averaging 1800-1900mah charge rate with it. Next highest rate cord only gets about 1200 max. I plan on ordering 2-3 more. $5 and change with PRIME.

Thank you! This is exactly the type of review I was looking for!
:laugh:
Check this out. http://voyager8.blogspot.com/2013/04/how-to-choose-good-usb-data-and.htmlI found it while looking for the 6ft cable I used to use until it shorted from heavy use (bending a lot) and I got a pack of 10 short flat wire style 3ft cables. My 6ft one has a ferrite end and printed on it: 28agw/1p and 26awg/2c. It could handle 2A just fine, but this requires any wall outlet adapter that can output that amperage. The oem outlet adapter that comes with the phone says 2.0A output, but you can fine any 'reliable' one that has 2.0A output.
if the original cable is not 1800mA, there must be a reason
Get one of these

Hi
Hard to get something original for samsung nowadays
I have those monoprice cables but get different results every time I plug in (1698ma, 1300ma, 600ma, 460ma, etc...)

I was using the 2A charger that came with my Nexus tablet. But I bought an additional one for work.
iXCC ® Dual USB 4.2 Amp (20 Watt) SMART High Capacity [High Power] ... http://www.amazon.com/dp/B00HPTU0OU/ref=cm_sw_r_udp_awd_PR7.tb01EM5CB
$11.99 thru PRIME.
Had this one for almost 3 months now and it works VERY well. I get a full 1900-2000mah charge rate on the Note2 and can charge my tablet at quick speeds simultaneously.

some fake cable limit current.
Got similar problems as the OP. I wanted to charge my phone in my car and using the phone as a navigation device without depleting the battery (which occured a few time).
Tried several usb cables, even did some mods like shorting the white and green data wire in the cabel at the phone side, but that all didn't help.
Then i came to Kopi who sells usb cables which can deliver a full current.

Bought a few for 6 dollar each and am now a happy camper.

I just saw it. Why don't you email them and ask about availability? I had contact with Victor Leung ([email protected]).
So I am back again asking about power.
Since switching to my Nexus 5x I have had to redo all of my power supplies. I went ahead and pulled the trigger on the Google wall options but now I have a request for something portable.
What I am looking for is a battery pack that can output the 3amps to quickly charge the phone, I dont really care if it charges quickly itself. The reason being is I have a solar panel that can push 1-2 amps and I was planning on strapping it to the back of the bike or leaving it on the tent to charge the battery over time and then using the battery to charge the phone.
I actually just purchased this
http://www.amazon.com/gp/product/B00BQ5KHJW?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00
I got it for $21..99 on a lightening deal. Haven't tried it yet, but it outputs 3amps
I have an Anker Powercore 21000mAH external battery, using a USB A to C cable, Ampere reports charge rates up to approx 1700mAH. The lock screen reports charging rapidly.
The cable is a Pecham one, It appears to be good quality, nice and thick, braided cable and a positive fit at the 5x end. I was happy with the charging speed, having just read the google cable reviews thread not so sure.....

I own the Romoss Solo5, outputs at 2.1a and 1.5a. With a normal type C cable from CableMatters, I don't get rapid charging, but it does fill up faster than a generic usb charger.

Ill be curious to see what you get. My concern is they dont mention the specific output of the ports, just the overall 3 amp. I suspect its split across teh two ports in some fashion like most (where they can do 2 amps on a single port but then 1.5 across both)
I have a 2 amp charger but I am hoping for a 3 to get that max performance. The idea is I could use the phone for music, navigation, etc on the motorcycle and then get a very quick top up while breaking for lunch, etc.
You need a type C connector at both ends.
A USB type-C to type-A cable cannot and should not allow charging at more than 2A (0.5A for USB 2.0 standard), because that is the most allowed in the USB spec as mentioned by the Google engineer that's been reviewing Type-C cables on Amazon. In order to support 3A rapid charging you would need a battery pack with a type-C port on it that supports rapid charging. Even if a type-A port is capable of supplying 3+ amps, the phone will only charge at up to about 1.7A without the type-C port at both ends. I don't know of any battery packs that support the type-C spec yet, although I'm sure they're coming.
That is why I am asking. I dont care if it charges itself at 3amps because my sources wouldnt provide that anyway. Im looking for the battery pack itself to pump out 3 amps. Im holding out for one of those and until then I will work along with my existing ones.

Neat thing about this, you can use the OEM 5v 3a charger to charge it. Interesting to see if it charges faster than other options.
mysterious posted in the other thread that he/she ordered it. Im waiting with baited breath to hear the results. This might be the perfect all-rounder (dont really need the other ports but they dont hurt anything).
Could charge with my solar panels, could charge with the stock adapter and hopefully the phone quickly on a lunch break.
I love how none of these products ship to Canada, except the official Google stuff which is no out of stock.
Has anyone had issues using Anker PowerIQ chargers with the Nexus 5X? I've purchased an Anker 2nd Gen Astro E4 13000mAh 2-Port (3A Output) and when connected to the Nexus 5X it keeps connecting and disconnecting. It does not appear to be a cable issue (my old 2A charger works fine through the same cable). Meanwhile the Anker charges the old Nexus 5 without any issue - it's just the Nexus 5X that seems to experience problems.
I'm wondering whether it's Anker's PowerIQ having trouble working out the correct power draw for the Nexus 5X. If anyone's had similar issues with PowerIQ or other chargers, I'd love to hear potential fixes or confirmation that I'll need to switch it out for something else.
I have encountered the exact same issue with the Anker Astro E4 battery. At first I figured it was the cheap Aliexpress USB-A to C cable I was using, but I think you're onto something about the PowerIQ not knowing how to negotiate with the 5X correctly. I contacted Anker Support on Twitter yesterday and was told to contact [email protected] about the issue. I haven't yet pursued that avenue, but I'll update once I have.
I don't think I have any issue with my PowerIQ non-quick charging 6 port desktop charger or 2-port battery park (15600 mah)
I have the same issue with my Nexus 5X. After I posted a negative review due to this on Amazon, Anker reached out to me and has shipped one of their 4 port chargers which they think will resolve the issue. We shall see...
It still could be a cable issue. The difference is that your Anker may contain smarter charging tech inside and it is self regulating what the cable is asking for (possibly 3A) when it cant really deliver that. With your other charger, it is possible it is blindly delivering an overcharge for its rated max and may brown out soon if not over time.

I honestly don't know, as I don't have an OEM type A wall charger to test it with. I would assume so, since it came from Google. I did receive Anker's 4 port car charger last night, but need to wait until this evening commute (once my battery drains) to see whether it works. Plugging it in this morning showed just "charging" when I was at 98%, but it wasn't cutting in and out like the 2 port one was.

My OEM cable is on its way as well. If you get a chance to test it on a different charger later on, please post the results. I would love to see that OEM cable say "charging rapidly."
Followup: I tested the Anker 4 port charger with the OEM Google A->C cable, and it does register as "charging rapidly." Using Ampere, I measured 1340 mA / 4.08 V peak to it. I also tested my new Tronsmart charger (with built-in USB C cable), which measured 1710 mA / 3.903 V peak.
I have same disconnect issues with aukey quickcharge battery pack
After a little back and forth with Anker email support, they are sending me an Anker PowerCore+ 10050 USB-C Battery Pack as a replacement for the Astro E2 not charging the 5x correctly - at no charge! Very impressed. It's been shipped but I haven't received it yet - from what I can tell spec-wise it has native USB Type C and A ports, but I can't yet confirm if this can fast charge the 5x at the same output as the stock wall charger.
I'll report back once I've had time to test.
sounds like an combo issue of the cable and battery pack/charger.
have you guys seen the thread about a google engineer (benson leung) reviewing usb -c cables?
basically usb-c standard cables should have a resistor in them which the phone uses to detect if the charger is able to supply 3A or not. without this (most cables seem to not have this, including the oneplus one) the phone thinks it can draw 3A and tries to do so. this can result in damaging you charger as that is more than it can produce. but apparently it can also damage components in your phone as the current it thinks it is receiving is higher than the actual current being received.
The disconnection issue sounds like the charger has a protection mechanism and realizes the phone is trying to draw more power than it can provide, so it cuts off to prevent overloading.
I tried the PowerDrive 2 and it has the same isse where it charges for a few seconds, stops, then charges for a few seconds, etc. I emailed thier support but have not heard back.
I have the same issue with Aukey PA-12, tried two different cables. The charger works fine with my wife's quick charging phone.... I hope it is a kernel issue that can be fixed. The original Google charger works flawlessly.
I'm having some issues with charging my 9T Pro (running xiaomi.eu miui 10.5 (9.9.6)), which I've had since August. Recently, if I connect the phone to no name 2A USB-A chargers, it will barely charge (or not charge at all). I mean like 1% an hour or so (it does say charging).
If I connect it to a PD or powerbank that does QC3, it will charge quickly.
Has this happened to anyone else? I'm thinking about ditching MIUI for LineageOS or something similar, so maybe I'll wipe in the future, but I'd like to avoid that if possible.
This just started happening the last few days.
It's not charging cause the charge controller is not able to negotiate current link with the charger.
Are you able to charge with the power bank with the same wire as the charger one or it's a separate cable for the power bank?
If it's the same wire then the 2a charger you mentioned is busted.
Thank you, I didn't think to change the cables but indeed I had 3 bad cables (I found one good cable by measuring charge rate with Ampere app, then checked all my chargers: all were fine, and one was even fast charging now when it wouldn't with the other cable).
Good advice, and the phone is happy again.
