Alot has been said about the quality of various batteries that we are all looking at for our devices...however very little about the different chargers that are out there.
I thought my charger that I bought was defective cause I let it charge overnight and it wasn't fully charged. That is not the case.
The Charger that the Note comes with charges at 1A. Most of these external battery only chargers charge at 350mA.
Take a look at this calculator:
http://www.csgnetwork.com/batterychgcalc.html
Using the link to the calculator above, you should expect a 2600mAh battery to fully charge using one of these cheap chargers in about 9 HOURS!! The charger that the note comes with should expect about 3.4 hours. That's a huge difference in charge time!!
So be sure to take a look at the output of these chargers before you get too excited and purchase one. If it takes you 24 hours to charge a battery, what good is it to you?
Thanks for the battery reference URL.
This is basically another scenario of 'you get what you pay for..'
It seems to often apply to batteries and chargers.
Whereas for like cases, you have a better chance of actually saving money and getting quality at the same time.

So I guess for battery longevity, you should use a 500 mA charger (the typical USB output). That way it doesn't charge it too quick (and overheat the battery).

No, actually. Lithium ion batteries, unlike nickle-cadium batteries actually perform and last better with short, fast charges. Android's battery stats are helped by a few full cycles, but it is not better for the battery to full cycle or slow charge.

*I am not an electrical expert, I just play one on TV.*
There are standards for USB outs. Just Google the standard. That said, there is USB1, USB2, and now USB3. Check your motherboard to see which one you have. There is also a newish thing on motherboards that will do a rapid charge by changing a setting on the BIOS. That's what i got off the top of my head. Do a little research.
As was pointed out on another thread, the Note looks for a low resistance/short between pins 2 and 3 of the USB cable. If it sees the low resistance, it enables a high current charge; otherwise, it sticks with USB standard charge of less than 500 ma. The 2/3 pin setup is not true of USB connections to a computer. The Note power adapter is set up this way to do a fast charge. Most chargers and portable battery chargers leave pins 2 and 3 unconnected, so they will not fast charge a Note even if they can supply 1A.
I purchased a Scosche 5000 mah battery with USB ports for charging Ipads, Iphones, and other devices. It also charges a Galaxy Tab with a special USB adapter plug. I tried the Tab adapter with my new Note and it was charging at 5 percent charged every ten minutes or so. Without the USB adapter, the Note charged at 2 percent every ten minutes or so. Without the adapter, the Note displays an MTP initialization notification. With the adapter, there is no MTP notification.
The Scosche battery is a big improvement over older Trent 5000 mah batteries. There is a push button to turn the Scosche battery on. The battery will turn off if no device is attached or it the device is fully charged. One of the ports can output 2.1A for an Ipad. The Trent battery would run down if it was left on.
Staples carries the Scosche battery for $80. I used a $29 online coupon from Staples that expires 3/5/2012.
I did not see anywhere on the Scosche website where they sell the Tab adapter by itself.

Do you have a model number on that USB adapter? Maybe in the instructions?
There is only the name Scosche on the adapter. The guide only calls it the Galaxy Tab adapter.

What does an "MTP initialization notification" look like on the Note? How do I identify it?
If I don't see it when charging, does that mean it's getting a fast charge for sure, or just that it might be?

How exactly would you use a multimeter to do this? From what I've seen, they have two contacts -- where would you stick those? Or is there some kind of micro USB conversion thingy to use with a multimeter?

Cut a USB cable, and strip a portion of the power wires. Set the multimeter to a 10A DC current scale (assuming it supports 10A, but most craftsman and up do, with common and a 10A lead), disconnect the plug, attach common to negative wire and positive to positive wire, gator clips or something, then plug it in and read it. The current support and time it can be on depends on the multimeter. Mine does up to 10A for Max 30 sec.

You need to look at the output amp rating of these chargers. Chances are the output rating is too low to charge the player. These players came with .75mA chargers and the one you are using is probably kicking out too little of the "juice". Even if it registers, I bet it will take for EVER to even go 5% charged... You need a better charger.

Batteries in the charger maybe not powerful enough, just because your LG phones charger has the same output as the SGP charger does not mean they have the same minimum power requirement to charge. remember 2 AA batteries is only 3 Volts and so the charger has a transformer (not the optimus prime kind, lol) that ramps the volt up, the problem is when ramping up voltage your dropping amperage and without knowing the amperage of the double A's your using is impossible to do the math to see if that would give you the min output to charge your SGP.
It's also worth mentioning that those AA chargers are meant to be an EMERGENCY BACKUP and you should NOT use them to regularly charge your devices battery as this method of "charging" and I use that word lightly is very unhealthy for your players battery.

Hello Seniors,
I have Samsung Galaxy S3 (I9300) international version and as my charger got damaged, I was using existing Nokia Micro USB charger with output of 5V & 1.2 Amp.
Samsung's original charger has got specifications of 5V & 1 Amp.
When I read about using higher current charger, many places it was mentioned that phone will charge faster. So I was ok to use this charger.
I can see that charging has become faster but the problem is when the phone is charging the screen do not respond to touch correctly.
Once I remove the charger it becomes normal.
So wanted to check if using this charger is there possibility of damaging the phone? And What is the reason that screen do not respond correctly for Nokia charger?
Looking forward for your expert advise....
Regards,
Anoop.

Hi, I had a very similar issue with my old Atrix 2. I too was using a higher current charger because I didn't have the original fitting for my outlets. I don't think the phone took any damage but the screen would sometimes not respond or most of the time just do weird **** when touched...
The 'charging' bit is built into the phone, the charger just supplies a constant voltage up to a maximum rated current. If you use a charger with an insufficient current rating the charge period is extended, like if you plug usb into your pc.
Using a 1A (or higher, makes no difference) rated charger will enable your phone to charge the battery at maximum rate, as long as the usb connector fits you can't go wrong.
Problems will occur if you use a cheap charger, or faulty one where a poor earth can mess with the touch screen. Throw it away and get the older type Samsung (one piece including lead) which are much better quality than the newer three piece ones.
Thanks Boomboomer for your input regarding this issue.
But one thing which I want to point out is, the Nokia Charger which i am using has got no earthing pin at all. It is just a plastic connector given at the place of earth pin. So technically there is no earthing. My samsung charger also did not have earthing pin it has only 2 pins (Indian Connector Style)
So I am not sure if that(Earthing) will be impacting in any way...
Please correct me if I am wrong...
No impact
Your capacitive screen relies on your finger changing the minuscule voltages within the screen, the faulty charger (or lead) interferes with these voltages due to poor shielding (the 'earth' of the usb lead). The charger needs no mains earth connection, but the usb connector shield has to have a good connection to the 'zero' point of the electronics inside the charger.
Try another good charger, or lead, and the problem will vanish.
Not to worry at all, you can even charge with the 2A Galaxy Tab charger. Just do not use black market chargers

Since I got my note 3 I've been charging it with my old AC chargers I bought on ebay which is a generic micro-usb charger (I got a couple of them laying around the appartment). I use my old chargers often because the samsung USB cable which was provided with the phone is always pluged into my desktop computer, and I didn't want to go trough the hassle of moving the cable all around the house to charge my phone.
Well anyway, so far I've notice charging times were pretty long(6-8hours), but I shrugged it off because I simply thought a bigger battery require longer to charge. But this weekend I slept off at my in-laws and I brought my samsung cable and AC adapter. I looked up with better battery stats and notice the charge time was around 3times as fast. (2hours or so for a 100% charge). Dammmn!
So why am I getting long charges with my ebay chargers?
Is it because they are cheap china product?
Is it because they don't have the USB3.0 port?
I'm thinking the USB3.0 has nothing to do with charging times if it's pluged with an AC adapter right? So my long charge time must be because of cheap products? Ok then, but if I want to buy additional chargers, or even a cradle for my bedside table. How can I know if they will have the best charge time? Am I forced to buy samsung branded stuff just to make sure?
Cause I'd be interested in something like this :

but I'm not gonna buy it if it takes double/triple charging time..

The Note 3 should charge in just over two hours with either USB 2 or 3 cables. If you download https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free&hl=en that will tell you the charging current. It should be 1200mA with the screen on and 1800mA with it off (trick is turn the screen off for 10s then back on and refresh and you should see 1800mA).
As long as the charger can deliver 1800mA and you are using a decent quality cable that should be all you need. Plugged into a USB port you'll only see 450mA on either USB 2 or 3.
Usually the ones that charge this quickly have an output of 2 amps. That is the output of the charger that came with the phone.

wow thanks there lots of useful stuff
With my Note 22 I used an app called "Galaxy Charging Current". Unfortunately it doesn't work on this phone. With the best charger & cable, the Note 2 showed 1800mA charging. I am looking for an App that would give me similar information with the V10.
Ampere seems to work with the V10:
https://play.google.com/store/apps/details?id=com.gombosdev.ampere
currently using Ampere but getting mixed results
I use GSAM Battery Monitor.
with GSam & 35‰ charged it said the charger was charging @ 196mA. If that were so, then the factory fast charger is defective.
With Ampere & 45% charged it said the charger was charging @ 930mA. If that were so, then the factory fast charger is defective.
My Note 2 charges @ 1800mA and does not know what a fast charger is.

quick charge 2.0 increases voltage to phone and drops the amps.
so a 5v 2.4a charger will put out around 1800mA (1.8a) on a note 2, the V10 with QC2.0 @ 930mA is prob feeding phone 9-12 volts

930 on a V10 is "the same" as 1800 on a note 2?
I also came from a note 2 and have been confused as heck trying to figure out if my v10 is charging at a decent rate.
I never have a problem with the oem charger but I was on a car trip and using an external battery pack and also tried plugging in to my car stereo but couldn't figure out how to "read" the charging apps.

Take note that the v10 turns off fast charging while screen is on. And ampere is a gesstimate, no app can give you presice. Need to use a USB Doctor sleeve for better results.
Unfortunately Ampere remeassures every time the screen turns on. I used the paid version widget.
Additional note. Fast chargers and fast charging is not the same as Qualcomm Quick Charge 2.0.
A 2.4A charger will not quick charge qc 2.0 LG v10 in this case any faster than an old Iphone cube.
You need a qc (qualcomm) 2.0 compatible quick charger and decent cable. Zerolemon, aukey, tronsmart, Motorola turbo qc 2.0 chargers works great.
The LG v10 is capable of 2400-2850mA. Slightly slower then the Nexus 6, but faster than the G4.
The stock charge that comes with the v10 is qc 2.0 [email protected] or [email protected] max. Some chargers can do 12v, ZeroLemon is one.

Yes in my experience, the quality of the cable makes a difference. I'm not sure if its the actual thickness or connections. I have a 6 foot braided flat cable that doesn't always fast charge on wall charger, but I have a 3 foot flat that does in the car. When I use my better cables it works every time.. I don't know if length makes a difference.
Yes, when I was using my Samsung Note 2 and an app called Galaxy Charging Current you could see the difference in mA. Using an Anker charger and a good cable got it up to 1800mA. It is harder to find longer cables that do not produce a loss. The quality of the conductor (metal /copper) shows up here. I wish that "Galaxy Charging Current" worked on the LG V10.
