Have noticed that the output on the Note II charger is higher than it was on my S3. Does anyone know where I can get another genuine one or equivalent travel one with the same output. Have used my friend Google but no luck.
Also, can a usb cable also affect the charging rate. e.g. I am currently charging my Note II in work with the original charger part but different usb cable and is only on 70% after 3 hours where as at home with rthe genuine usb and charger part it would be fully charged by now
Here is a 2 amp car charger which would charge your phone in roughly an hour and a half (3.1A/2A).

I am travelling at the moment overseas (for work). At home my 10.1 usually charges every night in a docking station. I bought a spare lead and my trusty multi pined (world Wide) USB charger that I use for my phone etc when I travel. When I plug the Pad into the charger it only charges at about 5% per hour so from dead flat it takes a whole day. At home its recharged in a few hours. What gives?? The charger is plenty big enough and doesn't even get warm. I tried a different charger (Not a Samsung Charger) and I get the same charge rate. Any body know if there is something special about the charger and if so how can I get around this problem in the short term.
Next time Ill just bring the Samsung charger

You need a 2 amp charger. Most normal USB chargers are only 0.5 amps.
DanielNTX is right. Our toy has a 7000mAh Battery. The normal charger provides us with 2A per hour which - by using maths - makes the tab charge from 0-100 in about 3.5 hours (slightly more as you have to calculate efficiency loss and also the tab uses power during that time (Wifi, 3G, whatever's turned on)
Phone chargers usualy only deliver 500mA (or 0.5A) per hour, some more (The Blackberry charger provides 700mA for instance). Depending on how much Amp your phone charger provides, it can take longer, in the case of a 500mA charger it takes 4 times as long. (14 hours+).
It is really hard to find a good wallcharger that provides 2A that is not either flimsy as hell or pricy. HP had a firesale a few days ago where they sold their Touchpad charger (5.3V, 2A) for a cheap 5€ (including shipping) unfortunatelly my order got cancelled due to the high demand, but you should definatelly search for a charger with a higher amperage.
Yes yoar are correct the Charger I am using although physically large is only one amp.
Looks like I am in the market for a 2 amp charger
When you are charging, is there a red cross through the battery symbol in the bottom right of the screen?
If so, then the problem is that your charger does not signal to the tab that it is a charger and so the tab will only trickle charge (as it would from a regular USB port).
The solution is:
a) to buy a tab compatible charger which sends this signal
b) buy an adapter to send the signal, search for somethig like "Samsung Galaxy Tab P1000 New PC Charging Power USB Cable Adaptor" on eBay
c) if you have electronics skills make up a little circuit to fool the tab. It involves soldering a couple of surface mount resistors between the +5, D+, D- & 0v. Several pages around on it. Here's one I found in a hurry, sorry, can't post links yet... h t t p : / / forums.webosnation.com/hp-touchpad-accessories/314741-how-get-full-power-charge-mobile-battery-car-hp-touchpad.html
I can't find my original wallcharger anymore
I use the original usb-cable and the charge unit from my SIII but it's slow as hell. And when the tab is on most of the time there is a red cross on the battery. It's very sucky
Just go find any old wallcharger that provides 2 Amps then. I bought a second original charger off of amazon for "just" 15€. It's not the cheapest I could find, but easily the one I trust most not to burst up in flames
I would recommend staying away from cheap, flimsy adapters.
http://www.amazon.de/Samsung-ETA-P10E-Reiseladegerät-inkl-USB-Kabel/dp/B0044EAVB6/ref=pd_cp_ce_1
EDIT: I suspect the SIII charger does not output 2A, really. Such a poweradapter is very uncommon for phones (I have not seen one with such an amperage yet) and only common for "high power devices".
EDIT2: If it is this one you have (http://www.amazon.de/Samsung-ETA0U8...D2LC/ref=sr_1_4?ie=UTF8&qid=1345112597&sr=8-4), then yes, this does not provide enough power for the Galaxy Tab. This has an output of only 1A.
EDIT3: For you, my belgian friend: http://www.amazon.fr/Samsung-ETA-P1...AVB6/ref=sr_1_2?ie=UTF8&qid=1345112860&sr=8-2
a bit more expensive than in germany, but you have free shipping to belgium
Buying a 2A charger won't do because the tab is limiting the current it draws from the charger unless it detects the original charger. This is to comply with the USB standard maximum current of 0.5A. If the tab drew more current from a standard charger, chances are good that the charger either shuts off due to overload or simply goes defect.
To use a 2A standard charger using the full current, you need to buy/build an adaptor cable to fool the tab into thinking it's hooked up to the original charger.

I use the original charger and I get the red cross. Damn Samsung QC...

slow charging WITH samsung charger?
I've been using the samsung wall charger from the box with my galaxy tab 10.1 and a few days ago it started to only trickle charge when plugged in with it. It charges like 3-5% per hour, and says its "discharging" in the battery menu while its plugged in. Thing is, the charger I have is frayed a bit at the male-to-tab (not male-to-block) side of the cord. Could this be causing my problem? I don't want to buy another charger for no reason, but I also don't want to send in my tab for weeks on end to find out it was the charger...any advice?
I'm looking for portable (camping/hiking type) solar charger for Samsung Note 2 (T-Mobile version). Just bought GOAL ZERO Nomad 7+ Guide-I/O Plus (which is AA/AAA battery bank. When I plugged in my Note into the solar panel instead of charging it was draining battery, so after 2 hour I wen from 35% down to 19%. I did testing on the battery bank (from USB to micro-USB on the phone and it works fine). So my question is:
1) is it possible that the panel is defective or Note2 is simply so incompatybile with the whole world ?
2) is there any other nice solar kit that would work and at the same time is small and light enough.
This is also possible because Note-2 (as well as Galaxy-3) uses 11 pin instead 5-pin USB pinout...
Eventually I would like to charge also my Samsung SLATE-7. I plugged it to the panel through the lighter outlet (as I have an extra charger that takes the power from the lighter then converts it to the higher voltage/amps - I believe is is around 19-20V). The only problem is that (as I herd) charging this way would be pretty slow. I have spent several hours last two days trying to find something that would work but after my several bad experiences with Samsung I have to be 100% sure when I order something on line. In this case I was lucky as I bought Nomad-7 at REI store so I can easily return it. I've seen several nice chargers on line today but at this moment I cannot be sure that anyone of them would work.
Any advice appreciated.
The note 2 requires at least a 1 amp output JUST to run while you're using the device (ie screen on)... It will charge slowly at 1 amp with the screen off and the phone not in use.
1.5 amps is recommended minimum to charge while you're actually using the device...
2 amps is the stock wall charger...
USB 2.0 output is only 500mA... Which is enough to trickle charge the note 2 while not in use.
So basically... look for a Solar charger that has at least 5v 1amp (if not 2amps) USB output. That should charge it. Or it my opinion? Invest in a 11,000mah + External usb battery and separate Solar panel kit. Most solar kits come with dinky 4000mah or less battery packs which is barely enough to charge your phone once. (if that)
Recently, my sgn n7000 charger(1yr old) got damaged.
I am looking to buy new charger of same model, but after searching a lot, i coudnt find a new genuine charger online, most of them are boxed and loosely packed.
i got some gud deal for a charger but its 700ma, it will take a lot of time to charge..
While searching, i got at these product
http://www.ebay.in/itm/Buy-Online-S...?pt=IN_Mobile_Accessories&hash=item3384a4ebb8
but on the samsung website, the note n7000 is not in the compatible list.
i wanna know, will it charge my note properly or not. Will i t damage my battery..!
or else pls give some link whr i can get genuine charger.

The charger looks like an indian version of the one my daughter received with her galaxy s4. White is the colour of her phone and the colour of her charger, it also was 5v at 2A. To my knowledge the charging of the battery within the phone is controlled by the phone and as long as it is supplied with its minimum requirement of 5v. it will charge at whatever current it can within the control of the power management in the phone.
Hope this helps ? I did look at the samsung website in india and they had power units for sale. I dont know where you are ?
Samsung India has 700ma chargers listed..
And do u charge ur note with that one..? Us thr any problem.?
charger
No mine is a 5v 1A samsung charger. I also have an incar charger which is a standard usb charger for any make of phone and that supplies 5v at 1A. I also have a Yiboyaun unit from china which charges just the battery, I have 3 additional batteries I use and charge with this unit from china. I have had this setup for more than a year with no problems.
You can charge N700x with the Note 2 charger (which puts out max 2A). It charges slightly faster than the original Sammy 1A charger/cable. It's perfectly safe because the phone will not take in more current than it's configured.

If it charges faster than 1A its not limiting the input. The note 1 battery is made for 1A chargers. Using 2A will limit the life span of the battery.
hi. the battery charger that i got with my LG optimu G Pro is ****. its just now that i checked that i have been deceived
its chinese copy and its only 0.2A charger...
now i know the reason why my phone charges soooo slow...
anyways. i think Note 3 and iPad air charger are 2A and 2.4A. so can i use iPad or Note 3 charger to charge my phone? will that be ok?
any one here using that?
thanks
Use OEM LG charger with 1.2 output. I am using LG G2 OEM charger and it charges very fast! But not sure it's compatible completely
Sent from my LG E988
If youre tech savy you can make your own,you just need a switchmode 5v regulator (they usually put out up to 3 amps) and you put a resistor across the data pins (i think 100 ohm) and itll charge the phone as fast as it can safely charge. I made my own charger for the car and the phone gets fully charged in about an hour and a half. (With screen on and playing Bluetooth music). Other wise if you buy a charger, get as many amps as you can. Atleast 1.5+ . and to make the phone charge in AC mode if it only says USB you need a resistor across the data pins.
Thats funny... my G Pro came with a 1.8a LG charger, my G2 came with a 1.2a.
Yeah you'll be fine. The "extra" amperage in the charger is available capacity that your phone can draw from, it will regulate itself but that can also depend on the charger and how they pin the USB. Its different than if you have extra volts (like a 10vdc charger which would provide too high of a voltage and damage electronics). I usually charge all my phones at when I get home with my wife's iPad charger super fast. Likewise you can use your LG charger to charge the iPad but will be slower since it has less amp capacity to supply. Part of the reason they provide the bigger charger is to sustain battery level while using the device (It should be large enough that the battery doesn't drain while your using the device while plugged into the charger).
Most computer USB ports typically provide .5a of power and will be your slowest charging option, at best you get a newer laptop with "high capacity" ports and it provides only 1.0a.
I've been using an iPad 1st gen charger with GPro since day one, been working flawlessly for 4 months now. Charges fast.
Hi Guys.
First off, I'm new here, and I did use the search function. However I did not find anything to my problem in particular.
I have a Lenovo Tab 2 A8-50 (it sucks, I know that by now).
I have 3 different original charger with the original cable that came with the devices.
1x Samsung Galaxy Note 5 - Adaptive Fast Charging - 5V, 2A.
1x iPad Air - 5.1V, 2,1A.
1x Lenovo Tab 2 charger that came with the device - 5V, 1.5A.
If I use any of those 2 other than my Lenovo charger, the charging process is incredibly slow.
For example, with the Lenovo 1.5A charger it takes about 90 min to charge from 25% to 100%.
If I use the Samsung or iPad charger, which have 2A , it takes 4-5 Hours!!
How is that possible that a 1.5A charger , charges faster than a 2A or 2.1A charger? Especially by so much?
I thought a higher Amp charger gives you shorter charging times?
Thanks
