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.

Thank you for this information, very helpful as I have other phone chargers. Is there a way(Windows based utility) to tell how many mah a USB port is outputting while charging?

*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.

Does anyone know if the charger pack u charge to act as a charger for your phone (when not near electricity)is compatible with the note? I've seen them but i didn't know if they are compatible with the note since it has such a large battery. Also does anyone have a link to one?

I just bought this Anker one from Amazon. Reviews are almost overwhelmingly positive and I can confirm that it does work on the Note just as well as it works on my Atrix 4G.
http://www.amazon.com/Anker-5600mAh...5?s=electronics&ie=UTF8&qid=1330474615&sr=1-5
Does the higher the amount of mah on the battery pack equate to numerous recharges for your phone(depending on the phone's battery mah)?
Sent from my Galaxy Note
Yup. It's just shy of three full charges for my Atrix, which has a ~1900mAh battery. Should be two charges for a Note, give or take a little bit.
That's great! I just saw one on amazon with 11200 mah for $69 i think im going to get it.

How long is the charge time on yours? I've never had one so i don't the slightest idea of how long it could take to charge one.
Sent from my Galaxy Note
I was going to get that one, but it was just too huge. I can slip the Anker 5600 I bought into a jacket or pants pocket with the cable and it's just fine. No problems with portability. Charge time is equal to what it'd be from an AC charger in my experience so far, but I only got mine a few days ago.
I meant wats the charge time of the battery pack?
Sent from my Galaxy Note
Haha...sorry. It was about half-charged when I got it (2/4 indicator lights) and took two hours to charge to four lights.
I got the mycharge ones since the cables are built in. 3Ah and 6Ah depending on my needs (1 or 2 nights). I like them even though they aren't 10Ah monsters.

Does it hold the charge or do you constantly have to recharge it?
Sent from my Galaxy Note
Most portable USB battery chargers do not support the signals that allow the Note to go to high current charge mode. Pins 2 and 3 of the USB connection need to be shorted with a low resistance. The Note senses this and switches on a high charge otherwise, it will stick to a standard USB charge of less than 500ma even if the battery charger can put out 1A.
I bought a Scosche 5000 mah portable battery charger that comes with a special USB adapter designed for the Galaxy Tab. I tested it with my Note. With the adapter, the Note charges in under four hours. Without the adapter, it takes overnight to charge the Note even though the Scosche has a USB port that puts out 2.1A to charge an Ipad.
Staples sells the Scosche battery for $80 but there is a $29 online coupon that is good until 3/5/2012.
Hmm... I have a rechargeable battery from Monoprice that I use with my iPhone 4 but I haven't tried it with my Note yet. It will probably only charge the battery about half way. Monoprice has good cheap rechargeable batteries to charge on the go if anyone is looking for something similar.
After a few more days with the Anker, it charges my Atrix and my Vivid at least as fast as my AC charger. Probably placebo effect, but it honestly feels like it charges it faster.
Why not just carry a couple of extra batteries and get a charging station for them? Seems cumbersome to have to have one of these attached to your device when you need more juice, when swapping out a battery is quick and has an instant full charge...?

If you're gonna carry something anyway you might as well just have a single, spare battery instead of a power pack plus a cable. The Note has such an easy back to pull off and swap. Bing-bang-boom.

As someone who used to do this exact same thing with the captivate, it's definitely convenient to carry, however the interruption while you take off the case, remove the cover, replace the battery/reboot, can get annoying especiallky if you're right in the middle of doing something.
I'm getting ready to take a long plane flight, and I bought some battery packs from monoprice just now, with the intention of using one of them up front while I use the phone, so we'll see how that goes.

Note sure if it's just me, but the minute or so that my phone is down to swap the battery and reboot seems much more appealing and convenient than having a battery pack dangling by a cord from my phone for multiple hours while it charges, or keeps it charged.
Not to mention how many spare batteries you could buy for the price of one external battery pack.

I actually agree partially, however I just found out that monoprice.com sells 2800mah battery packs for like $13 each. I just bought three:
http://www.monoprice.com/products/p...=10833&cs_id=1083311&p_id=7664&seq=1&format=2
That said, I likely will still buy an extra regular battery that I can just carry in my pocket. The main reason I'm going with the external batteries is because I'm getting ready to go on a trip with 15 month old twins to europe, and I can use these external packs to power up both my phone, and my touchpad (Which I need for playing childrens shows)
Could you please give me your opinion on which one you would get for reliability and performance? I personally do not like the hump look on my galaxy note and rather have an extra batteries or power bank when I can't find an AC outlet and for travel. I've narrowed my choice to the following (can't post links; too little post):
Hyperion Samsung Galaxy Note 2 x Battery + Charger [amazon - $19.99]
Anker® 2x2700mAh Li-ion Battery For Samsung Galaxy Note Batteries for AT&T Samsung Galaxy Note + Anker USB Travel Charger [amazon - $24.99]
New Trent IMP120D iCarrier 12000mAh Heavy Duty 2A/1A Dual USB Ports External Battery Pack [amazon - $76.95]
Extra batteries are the best method I've found ...as you can store 2 or 3 in a pocket ....then charge later when you get to a power supply ...g
Extra batteries without a doubt, I have 3 extras so at least 2 are always charged in case of emergency. Very cheap too
I use a solar powered battery backup/charger, got it for only $18 and it already saved me a bunch. Not sure if I'm allowed to post the link though, google search "Solar Powered Backup Battery And Charger"
I have the anker 2 2500ma + charger kit off amazon. Works great. 1 caveat though. The wear and tear on battery cover from.removing the back will eventually wear out the tabs that lock it in place. I have already went through one of the flip cover cases because of this. Currently using the stock cover and notice oonly a little wear at this time.
I have this and love it. http://m.bestbuy.com/m/e/product/detail.jsp?skuId=3386191&pid=1218397307007
Charges a phone and has a 2.1 amp port for a tablet. Holds 6600 mah of power so it will charge the note 2.5+ times.

I decided to get the New Trent iGeek IMP99D 9900mAh External Battery Pack with free New Trent 5200mAh. It was on special on Amazon. It seemed to be the best for portability and convenience. Had the charger came with the ability to charge 2/3 batteries simultaneously, I would have gone with the extra batteries. I rather plug once over night and be done charging next morning instead of standing by to complete charging and swapping each batteries.

Test results:
Using 2 Amp USB port - 25% to 99% charge took just 5 hours 7 minutes.
Using 1 Amp USB port - 14% to 100% charge took 4 hours and 42 minutes.
Using Samsung supplied charger/cable - 21% to 95% took 2 hours 7 minutes.
Conclusions:
1. No difference in charge rate using 1 Amp vs 2 Amp USB port.
2. Battery pack takes twice as long to charge than the wall charger.
3. 9900mAh gaurantees at least two full charges.
So is this what I shoud typically expect from a 9900 mAh external power pack? Please share your experience. Is there a way to increase my charge rate using the battery pack?
So I have started using an application on my Note 3 that is pretty much a battery muncher, GPS, Data, Processing, Graphics the works. I am looking into some options for extending battery life with some accessories. I was originally planning on getting 2 batteries with a charger but I'd like to also consider a portable battery pack so I can share the power with friends. What I am curious about is whether or not the charger can support the 900ma/h charging rate. I was wondering if the standard usb port can support the power as long as its a micro usb 3.0 connector. To simplify I just need to know that if I have type A usb connector to a micro usb 3.0 connector can I charge my phone at the fastest rate. And does the output of the charger have to be at least 1A?

I own two battery packs. Both are from a company called PowerGen and I picked them up on Amazon.com. One pack is 12,000mah the other is 5,200mah. You just plug your regular charging cable into one of the standard USB jacks in the battery pack and turn it on. The larger pack has a 2A jack and will charge at a fast rate. When I was using the Note 2, I used a special heavy duty charging cable that I picked up on Amazon.com and that cable allowed the Note 2 to charge at a faster rate. I have not tried to use the cable on the Note 3, but I might soon. I feel that battery packs are a much more flexible approach than extra batteries. You can get more than one recharge on the battery pack. I addition, I use the battery packs with a large number of other devices. If you get a new device, the battery pack can still be used.

YUp. I have an old anker external battery with 1a and 2a ports, the 2a port charges my note 3 at 1800. To be fair it is picky over the cable used (a decent quality non ribbon cable) and the temperature of the phone and battery (thermal throttling which is perfectly sensible to avoid cooking the battery and phone). It appears that there is a lot of variables that can potentially screw up a decent charge rate for some folks some of the time. My experience with the anker battery pack has been excellent, even nearly 2 years later after daily use.
Personally I am getting a little tired of the whole charging the battery twice a day so I am looking at a larger battery. The zerolemon allegedly affects signal quality, the 6400mah ones from elsewhere seem to come with shocking cases so I am still looking. It would be great if samsung came out with an extended battery and case. You think they would be after that money.

How do you check what the charging rate is And id like a cable that bends with no resistance unlike the factory cable .
Theres a free app "galaxy charging current lite", seems to be pretty accurate compared to time taken to charge.
As for the cables. I checked quite a few cables and I noticed that the higher quality cables, more expensive, thicker, better connectors etc were far more likely to charge at a higher rate. I would not be shocked if some of the cheaper cables, especially the flat noodle types were skimping either in the cables or the shielding. I could be entirely wrong of course but I did attempt to limit any other variables like being in airplane mode, low room temp, battery not near fully charged.
Don't get me wrong, I find it a huge PITA using a stiffer cable but that is why I am looking for an extended battery that doesn't leave me with the worlds worst case or stuff up the signal.

Has a dimmed LED that changes from blue to green when you plug up a fast charge device.
It's a dual USB port charger.
Input: 12-24V
Output 1: 5V 2.4A
Output 2: 5v 2.1A/9V 1.7A/12V 1.3A
I really like this unit. Works better then the crappy one i used to own by Qmadix. That one always seem to stop working after 2 weeks of use.
[Quick Charge 2.0 Car Charger]CHOE 30W (with Most Powerful QC 2.0 Port) Dual USB Car Charger with Micro USB Cable(White) https://www.amazon.com/dp/B00YX7Y3G8/ref=cm_sw_r_other_awd_GxKlwbPTT27F2
PS. the Choetech C0046 does come with nicely built 3ft USB cable.
I received this charger couple weeks ago and have been using it. The charger arrives in a nice package with the standard accessories. Inside it has the charger, the usb cable, instructions manual, and a pamphlet that ask if you're happy with the product or not. Pretty standard nowadays. I got the black charger but they also offer it in white. The charger is shorter than my other ones which is a plus for me. I don't like them to stick out of my car port since it's really close to my shift knob. The charger comes with two usb ports. 1 is for quick charge 2.0 for some phones like my galaxy note 5. The other is a normal port that charges pretty fast too, up to 2.4 amps. You can use either ports to charge your devices and they will charge to the max allowed but if you have a quick charge 2.0 enabled device, it's best to use that port. They colored the port blue for fast recognition which is nice. I don't have to fiddle around with it while I'm driving to figure out which port it is. The quick charge can charge my phone from 50% to close to full in about 45 mins. It takes longer if the phone is being used. I use the charger daily during my drive to school. I always charge it up to 100% before I head to class so it can last me all day. I was worried that by using quick charge so often, it would deteriorate my battery life but I haven't experienced that yet and hope I never do. When I use the charger to charge 2 devices, they both charge at their max. My phone charges with the quick charge while the other phone charges with the other port and it doesn't affect each other, which is very good. I really love this charger. If Iphones had quick charge, I would buy this charger for everyone in my family.
Choetech also was nice enough to allow me to test one of these charger for them.
I found it to be an excellent charger.
I have copied my review from amazon here for the fine folks here at XDA.
I will try to answer any questions you may have, just post up a reply or send me a PM.

This is a great little charger, and I do mean little.
The size actually surprised me a bit considering this is a 4 port charger.
I expected this to be a huge block sticking up from my 12v car port, but it actually is a nice small charger.
I have 2 port chargers that are bigger than this is, enough about that, on to the review.
Looking in the package you will find:
The Choetech 4 port Quick Charge 2.0 certified charger
3' USB cable
Instruction manual
The USB cable is one of the best ones I have received with a charger in a while.
It is not thin and flimsy like you usually get.
The charger itself is made of a nice gloss black plastic and looks and feels like it will hold up well to years of abuse in your vehicle.
This charger does support Qualcom Quick Charge 2.0, meaning that it will auto adjust voltages and amperage to best charge you compatible device as quick as possible.
In testing I found this charger to be able to charge my LG G4 and Samsung Galaxy Note 5 in about the same time as my other Quick Charge 2.0 certified wall chargers.
This will also charger non Quick Charge 2.0 certified devices at the maximum rate they will allow.
I tested my LG G3 that is not Quick Charge 2.0 certified and will max out at 2.1a charge rate.
It got 2.0a charge rate from this charger which is great.
There is also a blue LED on this to help you find it easier in the dark.
The LED itself is dim as to not be distracting,
I have attached some pictures showing how small this charger is and me using it to charge multiple devices including 2 phones and a GPS unit.
I have had zero problems with this unit and am glad to have it.
I would recommend this to anyone with a car or truck and either multiple devices they need to use daily or a device that is Qualcom Quick Charge 2.0 certified.

I received this at a discount in exchange for an honest review, this does not change my opinion of the product in any way.
Hey guys,
I got to use this charger too. Having 4 ports, one with quick charge was really handy. I was able to charge my Nexus 6, Nexus 9 tablet, and an iPhone 5S all from the same charger without having any drop off in charge rate from any of the devices I could measure with Ampere (Nexus 6 & 9). Overall, there isn't much more to say that the other guys above didn't say.
Other thoughts:
It's really small. This thing packs a lot of power for its size.
It is scratch and finger print prone, but I plan on leaving this in the car all the time; so that doesn't really affect me.
The charging light changes color based upon normal charging (Blue) versus quick charging (Green)
NOTE: I was given a discounted product in return for an honest review. All opinions and statements are my own
I grabbed the 2-port charger at 10 bucks a couple of weeks ago at Android Police.
I wonder why there aren't dual QC 2.0 ones out there.

probably grabs too much power and the design to make that might be too complicated without having some power fall off? Personally, my phone is the only QC device i'd worry about and the rest could take the slower charging. But that's my 2 cents.
I have this charger, too, along with a number of other CHOETECH products. Their quality is top notch with affordable pricing!
I have this charger in white so it sticks out surrounded by all the black leather in my car, but that makes it easy to spot and I keep the white charging cable in the quick charge slot so I know which to use when my phone is low. It doesn't seem to charge fast while the phone is in use, but it does charge quickly if you just leave your phone idle and let the charger work its magic.
Even you didn't have a quick charge device, it's handy to have a two port charger. I'm happy with that product.
