Well Tokie, for your car, u can use something like this:
http://www.amazon.com/Energizer-Universal-Car-Charger-Pc-2ca/dp/B004YZI1T4
One of the ports will have a 1.5amp output and will suffice to charge your battery quickly.
And if you have a tablet or wanna go ultra crazy in charging your battery n burning it U can use something like this:
http://www.microcenter.com/single_product_results.phtml?product_id=0364269
That one has a 2.1amp output as well, enough power to burn a hole in your phone's battery LOL!!

I use 2.1 amp in the car and it charges pretty fast even while streaming spotify or radio through bluetooth with screen off. It helps to get through a day of heavy usage without swapping a baterry.

For those of you who are getting an external battery charger, will you let me know if it manages to charge the batteries to 100%? I currently use a universal battery charger, which worked great for my other phone batteries (would charge them quickly and fully, so when I popped them into my phone, it showed 100%), but for whatever reason, when I try to externally charge my Nitro's battery, no matter how long I leave it or put it back on the charger, it will only reach 88% or so. Then I have to fill up the rest by putting the battery in the phone and charging through USB. I know it's not my battery (I have two, and they both do it), so I'm just curious if other external battery chargers might be better. Let me know if it works for you! If it does I'll get whatever kind you have. I'd be super grateful, thanks!
I'm getting a legit LG battery charger specifically for the nitro. It'll take me about 2 weeks to get it (coming from LG itself in Korea) but when it gets here I'll try it n will let u know how it goes.

I ordered 1 extra battery AND the battery/batterycharger/cable from the ebay seller I mentioned earlier.
The batteries seem legit, they last just as long and have identical plastic casings. However, the two batteries I bought from ebay have a different sticker/label on them. They do not have the "FCC" markings on them or any other american legalese on them.
As far as the charger goes, it works great. I carry a battery in my wallet, one in the phone, and one in my backpack. I really like the peace of mind!
I also got mine from that Ebay seller. I'm confident it's legit. The build is identical, and it maintains charge and behaves exactly the same as the one that came with my phone. It's just probably the battery for the Asian Optimus lte, hence no fcc and different labeling. I'm not worried, and I'm pretty careful about batteries.
@red solo cup, do you know if the charger manages to bring the battery to 100%, ie, when you pop it in the phone and turn it on, do the battery stats actually say 100? My current charger brings it to around 90%, which is not bad, but if I'm going to buy another charger, I'd like it to max out the battery completely =) Thanks!
I have not checked Battery Monitor Widget immediately after putting in the battery, so I cannot absolutely confirm that the battery charges to 100%. However, I have noticed that the battery in the notification area was completely full, including the little "nub" on the left of it.
I will check this out when I get back from work tonight.
If the nub's full, it's at least at 95% I'm pretty sure.
Damn, I don't mind getting it from him, but he posted that it will take almost 20 days to a month for the item to get to me! That's frigging much too long for shipping something overseas. Things I get in China or HK doesn't even go beyond 2 weeks the longest.

I checked and the LG charger does indeed charge the battery up to 100%
@aquariuz: I really cannot recall how long shipping took as I ordered the battery on the 15, and the battery+charger on the 21st. I was away for the holidays, but by the time I got back to my place on the 28th they were both in my mailbox.
You're the best! Thanks a bunch! Ordering mine ASAP! =)
24v input
Has anyone found any dual USB (2.1a and 1a) with 12 - 24v input? I run crane and sadly in most of our cranes the Cig Lighter socket is running 24v.
I have a few 12 - 24v input single USB chargers with 1amp out but.. I'd love to find a dual. I have to run my speakers and charge my phone or mp3/RADIO -- seeing as how Optimus doesn't have a FM tuner

I found this on amazon. The specifications specifically state: "Input: 12-24V DC; Output: 5.0V DC 2.1Amp" Plus it is only 5.99+free shipping.
I have this and the specs on kensington's website state "Input: 10V-18VDC, Output (30pin/USB): 5VDC-3100mA.", So I assume that will not work.
so if i have to buy a car charger, what is the MAX specs i can use for the LG OPTIMUS LTE?
I just lost my USB wall charger and realized my spares don't charge as fast as my previous one...
My previous charger had my phone at +700ma while in sleep, two of my spares can do 400 and one can only do 200!
One time I used a car charger that had me at +900ma in sleep so I would like to try and find a new wall charger that can get me +900.
BTW all the chargers I have used have said they are 5v 1000ma, so clearly I can't just go by the specs they list- I need a first hand experience of a quality charger.
So I open it to the forums. Anyone here have experience of a particularly strong USB wall charger?
I got a good Motorola one on Amazon for pretty cheap and it's been going strong for a while.
Sent from my GT-N7100 using xda app-developers app
Well, you do need one that's 1000mAh.
You just need one from a reliable manufacturer that's not mis-labelled crap.
I'd just look for a quality brand. I got lucky with one for $1.50 on eBay but the seller isn't selling them any more.
Hm so I guess OEM or genuine name brands should reliably be up to their specs, then? Well, I guess I'm going to shop around for one that maybe says 1500ma or more because I believe my phone can take more than a 1A charger can give it, and it probably won't disappoint
Samsung note II have a battery of 3,100mAh, the charger is 2000mA(2A). but my i can use the same charger for my S2. so i guess that the amphere doesn't really matter. just that the higher the amphere of the charger, the faster it charge. But you sure need a higher amphere charger for bigger battery. Hope this help.

I've read that smartphones (at least android phones) have controlled charging circuits that will only allow for as much amperage as they are set to allow. So if you connect a 2000mA charger to the phone but it's limited to 1000mA then it will only draw 1000mA. However as I have noticed just because a charger says it can output 1000mA doesn't mean that it can. I have tried 4 different 1000mA chargers each with pretty different outputs- and if they don't output as much as your phone will take it WILL charge slower. The point of this thread was to gather information on which chargers are reliably fast and ideally economical ones (there's enough OEM chargers I can find for 10x the price of off-brand ones that would hopefully do the job right).
This is a review of Anker Astro E5 15000 mAh external battery: http://www.ianker.com/product/79AN15K-WA
Being familiar with footprint of their E4 battery, when Anker announced a new E5 model with higher capacity I was expecting to see bigger and heavier model with a typical 30% efficiency loss. I know I bring it up in a lot of the reviews, but labeled capacity of ANY external battery is not what your phone battery going to see. Its a total capacity of cells inside of external battery which gets converted to 5V usb interface output and then back to your cell phone battery while charging - the efficiency loss during the conversion reduces the actual capacity by approximately 30%, with some batteries close to 40% and others maybe slightly better to 25%. On top of that, a lot of no name ebay HK sellers have batteries with super exaggerated capacity where you will be lucky to get even half of what they advertise on the label. That is why I only trust a few brands, Anker being one of them.
Once I received E5 unit for review to my surprise, the footprint stayed almost unchanged and difference in weight was negligible in comparison to previous E4 gen. But you actually get 2000 mAh more in capacity to bring it up to 15000 mAh. The battery cells are changing and improving, and I'm glad to see that Anker is keeping up with a new technology. E5 external battery is not exactly feather light, but at about 11.1 oz and 5"x3"x0.9" is manageable and actually the same as Note 2 with Zerolemon battery. The exterior is solid plastic, no flex, and comes in either white or black. For this review I chose a white unit and found it to be great to cover up any fingerprints. The top has a large power button with dual functionality to also turn on built-in led light. At full charged battery capacity, the light could last up to 700 hours if you only use it for that purpose. Next to power button you have 4-led capacity/charging indicator in 25% increments. Charging input to the battery is a standard micro-usb and has 1.5A charging speed for a fast charging of this battery. Output is a dual full usb port, rated at 2A and 1A both of which can be used simultaneously to deliver 3A of combined current. Each port current output is regulated where I confirmed charging Note 2 from one gave me max 2A and from the other one only up to 1A.
This extended battery comes with usb cable and interchangeable tips for micro-usb, mini-usb, and apple 30-pin connector. Also, it comes with a convenient storage pouch for a battery, cable, and attachment. It also comes with a detailed manual and 18-month warranty card. But there is also a big surprise. I have been reading other independent test reviews of this module and it turned out to have an actual capacity close to 11,800 mAh. We are talking about 21.5% efficiency loss which is very good considering typical batteries of such capacity have it at 30% or higher. This mean you can charge your Note 2 with a standard battery almost 4 times, or easily charge Zerolemon and have some juice still left - all this at a max 2A speed. Overall, I'm very impressed with this battery and its performance!

Awesome! Thanks for this! What are you using to measure the charge that is going in to the Note 2? I have an external battery rated at 12,000mah, that has both 1A and 2A ports, and would like to see what it's actually putting out, as well as check some wall adaptors that I have. Thanks for the review! Anker is also one of the few brands that I trust as well!

I actually found it to be relatively accurate by comparing charging time versus charging percentage. Ignore "Now" value. Just look for Max/Avg as your charging currents. This app comes very handy for those without root, like myself, to measure your charging current.

Thanks!! Just tested it out. Like you said, the Now value isn't what the charging rate actually is. Took me reading some reviews on the Play Store to figure that out. The Now value is what the device recommends, while the Average value is what rate you're actually charging at.
I'm not sure how accurate it is though. While using my HTC wall chargers that came with my both my black Evo LTE and white one, the values are Maximum 900, Now 1798, and Average 900. I'm getting the same numbers while using the Samsung wall charger that came with my Note 2. I assume that 900 is correct for the HTC chargers, as they're only 1Amp chargers so I'm getting .9Amp from them. The Samsung charger is 2Amp though, so it should be twice as high as the HTC chargers.
EDIT : Just tested my 12,000mah PowerBank. I got 500 out of the 1Amp port, and 1700 out of the 2Amp port! Very happy with those numbers!! Especially it considering that it appears to be charging at a higher rate than my OEM Samsung wall charger!!!

Mike, which 12kmAh charger are you using? I know Anker stuff is universal for Apple/Android, while some other ones will drop your charging current to max 0.5A when connected to "apple" port. Another question, which usb cable are you using? Unless if its original Sammy cable that came with OEM charger or a cable like from monoprice with 24AWG/28AWG rating (thicker power wires to handle up to 3A of current), the cable itself its a bottleneck if its designed for a lower charging current. So for example, if you are using HTC charger/cable and then used their cable to connect to Samsung wall charger - you could be current limiting your phone (thinner wires, more resistance). And even if you are using OEM Samsung wall charger and cable - I noticed that in our house some outlets can't supply enough current depending on what other stuff is connected to the same shared power branch.

I think PowerBank is the brand, and Long March is the model. There is a long thread in the Evo LTE Accessories subforum (my other phone), and that's how I heard about it. I normally wouldn't buy an off brand accessory, but with many XDA members giving great feedback, and some have had it close to a year, I decided to try it out. Very happy that I did!! I looks a lot like your Anker actually. It has 2 USB ports for charging other devices, a 1 Amp and a 2 Amp, and also has a little LED flashlight as well. It works great and this app you mentioned showed me that the 2 Amp port is charging at 1.7 Amp(while using my HTC micro USB cable, so it may charge at an even higher rate using the Samsung cable), so I'm happy with that.
For the Samsung wall charger, I'm using the Samsung wall charger and Samsung micro USB cable. I do have it plugged in to a power strip though, so I'll have to try it plugged directly in to a wall outlet with nothing else plugged in. Thanks for the info!
EDIT : Update - after trying the Samsung charger in a wall outlet instead of the power strip, I'm still getting 900(.9 Amp). Maybe my charger is just not putting out the Amperage it should anymore, and I should just buy another Samsung wall charger if I want to get the correct Amperage. I rarely use my wall charger though, as I just use my external battery charger to charge my extra Samsung battery. When I do plug in the phone, it's usually in to my PowerBank while I'm sitting outside playing on my phone and drinking/smoking (never smoke in my house!).

What you refer to is Yoobao brand power bank model "Long March". Unfortunately, there is only one official reseller of Yoobao brand in US and its KeviKev (I reviewed Yoobao Thunder 13000 mAh from them before - http://kevikev.com/Samsung-Galaxy-NOTE-II-2-N7100-Cases-and-Accessories_c47.htm). Long March is 11,200 mAh model. Did you get it from Amazon or eBay? It's a Chinese knock off of Yoobao, but it doesn't matter since it works for you. They all use the same battery cells anyway, and original Yoobao stuff might be a bit more robust and have more durable plastic shell. But listen, if the one you have works - its all good and don't worry about it!!!
Strange about Samsung wall charger. Sounds like something is gone south. Btw, don't even bother buying anything labeled as "original OEM Samsung wall charger" from Amazon or eBay - it's all fake knock offs as well. For the fun I just look on Amazon reviews, and everybody complaining about Samsung OEM wall charger not even being able to supply 1A. That's a problem with Amazon, anybody can create a merchant account and list their product under original manufacturer listing. And the rest is history because you will never be able to find original Samsung part since everything else will be a fake copy But I assume you are using your original wall charger and cable which came from Samsung when you bought N2?

That explosion has nothing to do with Anker batteries. That was highly/almost 100% due to the black cheap/low amp charger. I had a random cheap black USB charger similar to that for charging low amp Emerson bluetooth headphones, which was 400 mAH output, and we charged my brother's IPAD 2 with it, and it started to smoke. Same issue happened when charging his S3 with that cheap charger. I think it was their mistake for providing such a terrible charger, which is why it seemed the white one was probably better. The lesson is: don't charge anything that has a higher capacity/requirement with something far below it's capacity - otherwise, you're just asking for a dangerous situation to occur. That's just my two cents and observation from what I have seen, read, and personally experienced
how to charge
Excellent and informative review! 2 questions (I am a novice...). How do I charge the charger...can I use either my iphone 5 plug (output 5V/1A) or ipad2 plug? And, when charging my devices, is it the 1A socket for iphone 5, and 2A socket for ipad 2? Thank you!

To charge the charger you can use any wall charger with micro-usb output. Since this is Android forum and Note 2 section, I assume you have one of those. Otherwise as you aware the charging cable for iPhone 5 is not micro-usb. But to charge your device, you can do that with any phone or tablet since charging/data cables have usb on one side (that will go into a charger) and whatever connector you are using on your device on the other side of the cable. In theory you can use either outputs.
Hello! Great review, I purchased it for 50 bucks on amazon 5 minutes ago because of the review. I am a noob, sorry in advance, I made this account to ask these two questions: 1: I just wanna use it for my iPhone 5, do i plug it in on the 1A or 2A? If both is ok, which one is better for the battery in the phone? 2: I will need an adapter, which one is better? Micro Usb to Lightning or 30pin to Lightning? I dont like the size of the 30 pin to lighting, so is it ok to purchase a micro usb to lighting instead? Does this affect anything like charging time?
Thanks for answering, have a nice day

You can use either 1A or 2A outputs. Your phone has a fixed charging speed and will not draw more current that it's limited to. So for example if iPhone can charger at a speed of 1A per hour and you connect it to an output that can supply 2A per hour - it will only draw at 1A per hour speed. BUT, if you have Note 2 which takes advantage of 2A per hour charging and you plug it into 1A port, it will be charging at half the speed.
Regarding cable, try to minimize number of connecting adapters. For example, you get a cable with 30pin connector and you can add 30pin to Lighting adapter to it, but with every connection you add resistance which going to affect total amount of current and can slow down the charging, etc. You want to have point-to-point cable. So I would recommend using USB to Lighting connector cable. Not micro-usb, but usb because charing ports on this external power supply are full size usb. Only the port to charge this battery is micro-usb because of a common connection with other charging cables.

I wonder if you could try something for me.
Could you find out if the Anker will supply a phone/device while it is itself being charged? Also, whether it will keep supplying the phone/device without interruption when its own charging supply is connected and disconnected?
I want to use it like a mini-UPS for my phone while charging it from my bicycle dynamo, but for this, it needs to cope with a charging supply which stops and starts, while continuing to supply any connected devices.
I think I tried it before, and it didn't work. These external battery devices are not intended to work in pass-through mode. I think there are some other ones (I'm 100% sure if that was NewTrent), but the vendor will not guarantee the device under warranty because of an additional overheating and cut of the efficiency. This will really complicate the controller of such ext battery where it has to keep balance between charging and discharging of the same battery at the same time. I'm pretty sure Anker stuff will not allow that because they have smart current monitoring functionality built-in in order not to overcharge or over-drain the device.
But it would be an interesting experiment where you connect ext battery to the outlet and to the phone. I wonder if it starts charging battery first until it's full, and then switch to charging the phone

I did just that yesterday, and it worked fine. Now, the anker would not actually increase its charge due to simpe physics: it charges with 1.5A from the wall, and my nexus 10 used 1.2A of those, and adding some inefficiencies on that it would likely mean that it would just hold a charge level in the anker battery, not increase it. But as soon as the tablet ramps its current draw down the anker would suck up any left over juice. This becomes even worse of course if you charge a phone at the same time.
One little note: The battery in this is not the most awesome (also the capacity measurement is a simple voltage-based instead of counting coulumbs). While charging with ~1A from the 1A port, when I added my nexus 10 to the 2A port the charge indicator actually went from 50% to 25%. When removing the tablet the LEDs indicated 50% charge again. This is due to voltage sag which is itself due to internal resistance of the batteries. Meaning: The faster you charge the more heat will be wasted in the batteries. So to really prolong the battery life you should actually charge slowly, at least as far as the Anker is concerned.
Thanks for the review, I will probably be getting one now.
