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

Although both says 2000mA, but does NOT work on SGT, I was lucky the retailer let me trial-run at home.
Results = takes 10 hours to charge from 10% to 100% same like notebook or desktop USB with software upgraded (USB fast charging from ASRock) tested on ASRock mobo and Thinkpas T60.
Make sure to buy only when box PRINTS for GALAXY Tab !!!

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.
adapter
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.

That's also what I want to know.
There is no reason why it wouldn't work. It's just like going on holiday... US plugs to Euro/UK etc
So that's the route I will end up taking. But I may purchase an out and out 1000mAh wall plug anyway... even a 2000mAh...

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 am lucky enough to have a note n7000 that doesn't suffer from any Wakelocks or battery issues.
I have 4.0.3 stock ROM installed, rooted with speedmod kernel 3-7 and carbon tweaks installed.
Phone runs great and gets a quadrant score around 4300.
I got an in car USB charging adapter. It is 5 volt 1 amp. The adapter came with a USB cable and I used that to charge the phone while on a 2 hour journey using GPS navigation and the battery was drained completely despite being plugged into the charger. Battery shows lightning bolt symbol and phone beeps to show that charger is plugged in.
I also left the phone switched off and plugged into the charger in the car for about 3 hours but that didn't charge the battery at all.
Any idea why it doesn't work?
Also real football 2012 used to work great on my phone but now it just won't load. I tried reinstalling but it still won't load up. Any idea why that might be??

It could be the charger or the lead - I presume the phone charges ok from the mains.
I have one USB lead that wont charge my Note if I'm using it at the time {battery capacity goes down), and I expect it's down to low cable quality with not enough copper so too high a resistance dropping too much voltage.
The best way is to test by substitution.

yep buy a genuine samsung car charger. I bought one and i haven't encountered a problem with it....
My sister got the GT-I9305 a little while back. Usually, she takes quite a few hours to charge it fully, about 7-8 hours. However, recently, it got worse. The phone has been sitting at 37% for over an hour now, and it is still stuck at 37%! I've searched for other threads on this issue but they didn't really solve my issue. It seems really weird that the battery hasn't even turned for the better(or the worse) after over an hour.
Anyone has any insight on this? Thanks a bunch!
P.S. Everything was off except for Power Saving mode and the mobile signal.
use a different charger, cable, port
i own that phone and i have to say that the charger is very weak 1000mAh charger for 2100mAh takes a lot i currently use my nokia's charger it has1200mAh and that makes a huge difference,my friend's uses nokia lumia's or of you have a recent computer you might have a supercharging port that provides much more power,
Hi everbody.
I use 2 different chargers, one from my tablet BQ Maxell Plus, other from another cellular...
NEVER had issues charging my I9300, with stock rom or other one....very fast and until 100%.
NEVER used the original one, but looking at it, is a joke of charger.....
Values: All debitate 5V, and 0.1 and 0.2 Amperes.
You must take in consideration other factors like electronic heat dissipation, filtrate, stabilitie, etc,etc with it seens not works well with the original one....
Who says that bigger ins`t better?:good:
1000mah is more than enough, must be a charger /cable problem

you guys are using capacity units on a charger. Chargers don't have any capacity, they have current, which is measured in amps, not amp/hours. So S3 charger would be a 1000mA or 1A, not 1000mAh
Never had a problem with the original charger. Charge time more than decent

how can that have an effect on the charging current?
On some cyanogenmod 10.1nigthlies versions it has problem with charging takes forever with oem charger, i am now on sentinel rom 4.6 it has same problem. Just use usb port from computer or some media player. It charge to full in maybe 5 hours from usb port, i dont remember excatly.
I agree the S3 Lte does not have the same speed in charging as the 9300 I use to own even though the chargers are the same, even different roms don't solve the issue, need a custom kernel to up the charging current that was available with the i9300 to reduce charging times

Hey Peeps
Anyone else getting slow charging on SM-T810?
Using the bundled charger, I am getting average of only 680mA .... Definitely nothing over 950mA and that is even when screen is off...
Using the same charger and cable on my sony xperia Z3 easily achieve 1400mA ...
Same sort of numbers with other chargers etc... So pretty sure it is device not charger...

I just tested and am getting around 1500 mA. That is with my nexus 6 charger.
Bundled charger gives me around 1460 mA.
Are you certain it`s not the app that is wrong as the S2 is new and the app might not have been updated yet, Try the Samsung charging app below, you have to keep pressing the refresh button on the free version.

The charging rate can be anything from 300mAh to the maximum the power adapter can output, the tablet will determine the amount of power it will accept, and will jump from fast to slow charge depending on how much more power is needed until it reach 100%.
Thanks guys - obviously does not seen to be wide issue.
I tried the Samsung app above ... Sort of showed similar values ....
I did a charge from 69% to full and it took about 1.5 hours... So would be maybe 5 hours to charge fully?? Unless the device does much quicker charging at very low battery??
I will do a full discharge down to say 5% and then charge from there and see how I go.

Normally it will trickle charge slow once it reach approximate 80%, and is normally fast if the unit is almost power empty.
It's annoying. I've tried both ipad chargers and a 2.4A charger, but it will go to slow charging mode with anything else than the bundled charger.

Yeah i have found exactly the same!! Must be some sort of Samsung handshake protocol...
There is another thread on this that I have mentions about this, just use a good quality charger, or just go for a Qualcomm QC 2.0 charger from any known brand like htc, aukey, xpower, lots to name, just searh Qualcomm site for a full list.
It won't used the QC2.0, but all should work just like the OEM Samsung one
the ipad charger should be pretty high quality though, so I don't get why it's being so picky.

If you also followed the tab S thread, it's also been mentioned, Samsung tabs S are also picky, and yes all apple stuff don't work.
Should I rephrase it and say some good quality charger will work, even branded ones like sony may not even work, but my intital testing, most QC 2.0 charger will work.
The issue is that I'm trying to find one charger that will charge both my tab s2 and my iphone 6+ quickly. Any idea how qc chargers fare with iphones? The bundled tab s2 charger only gave my iphone 0.4A (it charges the tablet at 1.5A)
I have both sony and asus chargers with included cables work perfectly with iphones and sony xperia z3 and nexus 7... Hopeless with S2.... But s2 charger works fine with them..

Odd, my old Nexus 7 2012 charger fast-charges my S2 710 without any issue at all. I had it spare as the N7 died on me (the S2 is its replacement) and was initially wondering myself as I had a few supposedly 2A chargers at home which only slow-charged the S2 (or indeed under Android 5.0.2 said it wasn't charging at all, even though it evidently was, but 5.1.1 has fixed that).
That said this is a charger without fixed cable (but with a decent USB cable) and I know from Raspberry Pi experience that the cable is almost as important as the charger for getting decent charging (ie enough current) to the device on the far end.
I would make sure the USB cable is a decent one intended for charging.
Proper charging USB cables have the shield connected at both ends for use as ground which is why they are notably thicker.

I agree, a good quality cable is required, as well as the charger itself, I'm using a magnetic cable and a reversible micro USB cable with a OEM Samsung, Aukey and Xpower charger, I don't get the speed of the QC 2.0, but it isn't suppose to as the S2 is not QC 2.0 compatible, but it does charge pretty quick, it also charges my ipod 4, and my nw-ZX2 work without any problems.
I get the "slow charging" message when using the Galaxy Tab S2 bundled charger.
If I use the charger from my Note 4 (Exynos) I get faster charging and no "slow" warning.
Did Samsung bundle it with the slow charger??
I can confirm that samsung did in fact bundle the tab s2 WITHOUT a quick charge usb charger.
I also thought the tab s2 didnt come with quick charge. I have extremely slow charge times but my battery lasts for DAYS... I can fully charge it, put it in airplane mode and check on it after 2 days and be at 98-99% battery.
I also use the quick charge cable AND the quick charge usb adapter that came with my note 5 and the tab still slow charges..
Here the same problem use Samsung charger and cable charge from 20% to 100% in 6 hrs and when use HUAWEI cable with Samsung charger It charged in 2 hrs
I guess Samsung have poor quality cable *-*
