this has been real hell finding information about whether this http://www.ebay.com/itm/Powerocks-p...y_Chargers&hash=item3cc55ca8b0#ht_4645wt_1163 is compatible with my Motorola defy+ (note custom roms, Switching from time to time, Currently on WIUI ICS) and other information such as how long does it last and etc.
has anybody used this?
is it worth the money and how does it translate to battery % on my defy+.
any other feedback?
and maybe other recommendations (with that price region)
and is there a thing like this that uses AA batteries, if so, how many will it take to charge my Defy+
thanks ahead
EDIT:
what's the proper name for that thingy? because this thing has wayyyy too many names,
power bank, external battery, portable charger, portable battery, extra battery. and many many many more!!! this is why it's complete hell finding information.
what's the real and most proper name for it?
Just a single word 'AVOID'
i don't usually like to be disrespectful, but.
you sir, have convinced me with your long list of arguments and good points of reason to support your advice.
could you please explain, why?
Ok. Here it goes.
I have used these chargers long back, I think around a year back. It barely charges 15% of your mobile battery (I was using a Samsung Galaxy Apollo at that time which had a 1500mah battery) with a single AA cell which I think is totally not worth.
I hope this is enough for you to get a fair idea
so, you're saying that the Portable chargers that use AA batteries are bad, or are you saying all these portable chargers are bad and charge too little?
if you're saying that all the portable chargers are bad and charge too little, then i would have to say that it depends on how much mAh the charger can hold.
say i get the 2600 mAh charger to charge my Defy+ (think around 1700 mAh) when it's completely out, i think that i will charge fully at least once (say around 1000 mAh at MOST! is lost because of the charging procedure)
i'm only talking about the AA battery based chargers. I don't have any idea about other powerpacks as I've never used it.
1 AA battery for 225 mAh!?!?!?!? that's awesome!!! would be great for camping trips, you get like 12 AA batteries (or more, depends on how long you plan to be away from charging your phone normally) and you can even play in the evening or even watch porn if you got Data signal!
i'm still probably going for the normal one, and maybe i'll get an extra charger that uses AA batteries in-case i go camping somewhere.
can people please give feedback on whether it's good enough? why are there only 2 posters?
I think that it works just seen a duracell one in a store near me wich holds 4 AA batts, i think on buying it and fillit with some 4 NiMh AA acumulators rated at 2700 mAh each, just think about it thats 10800 mAh in a portable charge, that will charge my Defy battery at least 5 times even with an extra burning that the charge does.

isn't there a case of voltage involved? (idk, i'm a complete noob in this)
and i need something smaller, something as small as the charger i posted.
i'm just curios to know if it works or not and any other feedback about it.

NiMHs are 1,2V which means, 2700mAh hold 2700mAh * 1,2V= 3,24 Wh which is the same as 11,664 kJ
The Defy battery holds 1500mah at 3,7V --> 5,5 Wh = 19,98 kJ
Taking efficiency in count you might be able to load your Defy with two fully charged NiMHs once, but i`d rather expect that two are not enough.
As for the that eBay-offer: The voltage is given as 5,1V. With 2600mAh that would mean 13,2 Wh. But i rather believe they are stating the capacity at 3,7V for marketing reasons. That would mean 9,62 Wh. That would allow you to recharge about one and a half time.

So someones after advice on portable power when away from the mains?
Ive been using a New trent imp1000 to keep things going, its a li-ion rechargable powerpack with a capacity of 11000mah and it keeps my Defy going for 4 days.
I also have a total of three batterys for my defy, and a universal li-ion external charger, called a cam caddy, although its designed to charge camera batterys from a 5 volt supply it also quite happily charges up the battery for my defy as well.
So for extreme use i can have a battery in use in my phon, plus a spare with me, and back at base ( or just overnight) a battery on charge in the cam caddy.
If im in an area with access to mains i will take the imp1000 and its charger to top up where and when i can.
I also have a universal USB charger with swapable plugs that fit all major power outlets worldwide.
And to top it all off a USB AA battery charger that will ( slowly) charge up 4 AA batterys form a solar panel, or from a USB input ( faster) , or output 5V through the USB out put port.
This little set up has kept me going for 14 days with no access to mains power ( except for a few bits here and there - 20 minutes at a bus station/railway station and so on) , keeping my phone going (defy) a high powered AA cree LED torch, a camera ( via spare battery+cam caaddy) and an mp3 player. the trick is careful battery management - on the defy turn off everything when not in use, except the ability to receive calls and number your batterys for ID, and the same for cameras etc etc.

i think 11000 mAh is a little too much for me, it may be good for camping trips and etc, but i don't think i'm gonna buy something that (probably) big and (probably) expensive. most of the use of the external charger will be when i'm out with friends for a long time, or say after school i spontaneously decide to go out with friends before getting home (unfortunately a 1 hour drive from friends city to mine) so i need an a portable charger so i won't get bored on the way back, my battery lasts a school day, if i go somewhere that is not home after school, it won't last.
about the extra batteries, are those original from motorola? if not, are they as good as the original? are they worth getting?
The batterys are official motorla ones, as i b ought a cheap un official one and that had issues ( wouldnt show the charge level on the defy )
The battery pack is a "new trent imp1000" which costs £30 from amazon.
I also have a dock for the defy in which my phone usualy sits, at the back of this dock is a slot for an extra battery, left overnight this will charge both my Defy ( with battery inside) and the extra battery in the slot, this is plugged into a dektop pc where some of the USB sockets are still powered up ( giving out 5v) even when the desktpop p.c is off
supdealer offers nice portable power bank
as portable external battery/power bank/portable charger, An ebay seller called supdealer sells a nice one. You can have a look.
It may help you. :laugh:
I have that new Trent battery, its perfect almost same size as defy.

Guys,
If you really want true power on the go, buy a YOOBAO power pack, the 11200 mAh one.
It is really a beast and is really charging a defy several times before going empty.

Yes, all iPhone compatible USB-Chargers are compatible to our Defy and other new mobiles.
Why? EN_62684: Common External Power Supply (EPS)
Why would I use Li-ion instead of AA Cells (NiCd,NiMH or NiZn)?
Higher Energy Density!
Another benefit of Li-ion is the discharging charakteristika (sorry for german captions).

power saving battery charger:
I want to buy this battery charger,
because I've buyed my HD2 from GB (I live in Germany)
and the plug doesn't fit
But I have some doubt about the specs:
ORG: 5V, 1000 mA
this: 5V, 1200 mA
will this make problems?
Sure this would be fine!
Should work fine. If it doesn't fit try finding an adapter. They aren't expensive these days.
Doesn't it matter what the power output is for the charger? The mah rating, or anything or are you guys just saying that any charger with a micro usb on the end will work and that the phone itself will regular the power?
Your phone needs 1000mA minimum, 1200mA is 20% better It will work very well with your HD2. If you don't like it, pass it on please, I'll take it off your hands

That's not correct, you shouldn't really be going over 1000mA, I got a micro usb charger off eBay for 1.75GBP and its rating is 650mA and it works fine.
So you can safely charge your phone with a 700 mah rating, and it will just charge slowly but will not negatively affect the battery life longevity or harm the phone correct?
One person said it has to be a minimum of 1000 mah, so that makes me worried of going below and using a 500 mah and having my battery get screwed up, or the unit blow up.

You can go below with no problems but there will be a minimum amount the phone will need to charge. My post above was incorrect about the charger i got, its 550Mah not 650Mah and still going strong. When purchasing chargers off Ebay i always buy from my home country, that way if anything untoward goes wrong i can go knocking on their door!
on chargers
what u guys should watch out for is the voltage not maH. 5V is what we need to pay attention to. If you use a higher voltage the battery will explode.
The difference between 550 mAH or 1200 mAH is the charging time. With 1200mAH your phone will charge quicker vs the 550mAH. Just think of it that you are trying to fill a pail with water. 550mAH is like using a small straw. 1200 mAH is like using a big pipe.
Hope this helps

This has been the most useful post in this thread thanks....
So, I have a Motorola charger for my BT headset that is rated 5V and 550mAH... I assume I can charge my phone with this safely without any adverse effect on the battery (just a slower charge)?
Makes sense as I think charging VIA usb cable and a laptop also takes longer... This would be great as I have a few of those motorola chargers lying around and won't mind using them for bedside overnight charging... it will free up another micro USB cable for me
I am assuming it will be ok cause USB charging from laptops/computers are about 4.7V at 500mah.... This means this little charger should be ok I think... I have ALWAYS left my phones connected for long periods of time to laptops/PCs... does not seem to affect battery lifespan. Can anyone confirm this or tell me differently?
im the "drop out"
yep looks like im the "drop out" i got coming from HK its only 350mA and even befor it arrive i look for another.
I see espansys have one 1500ma AC Adaptor but very expensive > but i suppose if want battery to last > good to get
So, I used my Motorola charger for my HX1 bluetooth headset to charge my phone overnight (with phone on). The only thing running was SPB time with an animated background.... The charger is rated 5V 550Mah..... all seemed to be fine at the begining.
However, this morning, I work up to a blank screen and the fully charged LED on. Even after unplugging, the LED stayed on and the phone was unresponsive. I had to remove the cover and pull out the battery to restart. I am wondering if it was the charger or perhaps SPB time? I will give it another go tonight without SPB Time v3.1.1 running to see if it does the same. I hope Im not destroying my battery!
Edit: I charged it last night from 5% till full with no SPB time running... no problems cool!
I am on travel very often and my last experience with my Desire was that when working on the phone with no possibility of charging it, I was left with very little or non battery late afternoon. Any suggestion for a good Travel Battery Pack anyone? One extra charge will do. Thanks
Probably better off getting a spare battery, and charge it up, most easiest way i think instead of carrying aa batteries and charge cases, leads etc.

i use solar charger it has built in 3000Ma battery you can also charge it from pc or adapter and ready to go with extra power. Have it from ebay for $29
Did anyone test any spare batteries from ebay? Thought of getting some, but not sure if it is worth it or not (the charge should at least be as high as the stock battery's) .
Got this few days ago from a china online retailer. Good construction and nice pocketable size. Slightly heavier than LG2X & about 20% thicker. Comes with 0.5A & 1A USB output.
So far, on 0.5A output, no in-charger lock ups yet - which I do get from some AC chargers.
Priced upwards of US$35. Google for "5000mah Power Bank".
will LG come out with an extended battery for the Optimus 2X ?
If they made 2 models. one like we have with a 1500 battery and one that is 1.2-1.4X thicker with lets say a 3000 battery I think almost everybody would choose the slightly thicker 3000 battery model.
These devices are small enough as it is, they should now stop trying to make them smaller as they are surely limited by the screen size, and make them last longer.
I had a Del Axim X50v a few years back that I brought an extended battery and battery cover for, this actually made the device feel better in the hand.
I think the future is not far... for batteries that are either running on gas or like these ones which can be fully charged in less than 3 min. http://green.autoblog.com/2011/03/23/new-battery-technology-electric-vehicles-recharge-minutes/

Only tested twice from over 70% to full on 0.5A. Took longer than using AC adapter. Tried it once on 1A but got a bit hot quite quickly, so I switched over to 0.5A. Also, it takes a while to charge the pack itself from partial empty to full on 1A AC adapter - so I am guessing the 5000mah claim is reasonably accurate.
I bought this item from DealExtreme.

It works fine, but the input broke after some uses and I had to fix it.

Hi Guys,
Anyone tried Solar Powered Battery Chargers?
Looking at this one here :
source : 6000 mAh Solar Powered Mobile Power Extended Emergency Battery - Obostore
I'm looking fior the same. I bought recantly GOAL ZERO Nomad -7. Instead of charging it drains the power of my Note-2. I guess it is because of the non-standard pin-out (11 pins), so this is the one I would definitely not recommend.

I haven't seen any positive reviews about any solar powered chargers. The problem is that you need to apply voltage (bias it) in order for it to work. Like those solar power panels on the roof of people - if you loose a power to the house, they will not work So they might be draining instead of charging lol!!!
Don't know for sure how it works and if it works and how efficiently. So if anybody has any real life experience, please chime in. Most of the big name external battery vendors don't want to carry this product. I only seen it on ebay and Aliexpress.
I personally haven't tried one. From what I've seen about them, they're very fast, and can be nick-picky about the angle to the sun. On top of it, you'll probably need to check what's the output versus what the phone needs to change.
I think you're probably better off finding some kind of crank mechanism and use that to change the phone. Plus, you'll get a little work out too; you'll live longer to enjoy your phone, 8)
I have a voltaic that I use when camping or on extended hikes. It comes with a 3000mah battery. I haven't used it on the Note2 yet, but used it a lot with my Fascinate. The battery works fine as backup power, though it charges slowly and the phone pretty much has to be off for it to be effective. It takes most of a day of full sun to recharge the contained battery. It's ok if you're going to be away from power for a week, but for less than that I think just an extra battery or two fully charged would work better.
I think we just need to find or build one that supports 2.1 amps (ideally) but anything over 1amp should do something.

I have one I found at Best Buy a couple years ago. It's a single amp box, so charges my Note II very slowly. I've used it on my bike when I'm out on rides. I have a mount for it and my phone. While riding, I use bluetooth headphones. It does work, but like someone else said, there needs to be one with 2.1 amps.
I as well have a Nomad 7, but mine charges my note without issue, although I will admit, it is impractically slow.
I bought this couple of months ago, charging the phone is a wii bit slow but it works like a champ!

I wouldn't mind if the solar power was a "backup" to a regular external battery, but if all it did was solar I wouldn't be interested.

WICKED... just stumbled across this on ebay. If you are a roll your own DIY type and want to charge a rapid charge device like Note2 or a tablet or something, this might be a great thing to look at.
http://www.ebay.com/itm/DC-DC-5V-36...018?pt=LH_DefaultDomain_0&hash=item2c700c47c2
I, personally, don't like the mini-usb connector... seems kind of goofy. I'd prefer just two wire terminals to connect solar panels to.
But yeah, if you've got high voltage solar setup... e.g. anything between 5V and 36V and want to have a clean, regulated 5V usb compliant output, this would likely be your guy. I'd also want to make sure it really does work with note2 - in terms of negotiation of currents higher than 100ma. YMMV FWIW
AND if you don't need note2/tablet 2A...
this guy seems like about the right fit.
http://www.ebay.com/itm/DC-DC-12V-2...965?pt=LH_DefaultDomain_0&hash=item4d0c738c65
Got it from eBay.
Charges faster in phone...while using!
If battery is around 40% it being be charged overnight.
Anyone else experience this?
could be the amp? maybe below 1 amp? Samsung charger has 2amps om it. check your charger and look for the amp. btw. the lower the amp the better for your battery..
Buy an OEM charger. The Samsung one is $50 from Samsung website but you can get the Asus charger from Google play store for $25. Both are two ampbi believe. Or you can get the 1a for $25 from samsung. Getting OEM directly from an OEM or authorized reseller or a storefront lime Google is key. Getting cheap chargers is gonna bite you in the ass one day or think about it like this. Why keep wasting time buying cheap chargers again and again when you can put up proper money and get quality in one go and have peace of mind for a few years. I even stopped buying chargers from amazon because they're just cheap knockoffs too. Phi hong makes good chargers and power supplies but they are harder to source. Phi hong came with my nexus one andy galaxy nexus OEM Home dock.
Anyways, aside from that part of the reason for slow charging is you probably have an unsafe charger that is not rated what it really is and is made of poor materials. Getting a quality 1a or higher, preferably 2a in this case and your gnote2 should charge @ 1.8a. In other words, you can charge from zero to full in ~2-2.5 hours. Or from partially full to 100% in less than 2 easily.

Unless I am mistaken, OP is referring to battery chargers, not usb chargers. That's how I charge mine, too. I have spare batteries, and they all get charged directly. When my battery is low, I just swap. I hate having my phone attached to a cord, even at night.
Yes, all the battery chargers I've had for every device (including this one) have been lower amp than the usb chargers supplied with the phone. It is especially slow for this huge battery for the Note 2. While it bothers me in concept, it's never actually been an issue for me, so I haven't done anything about it. I don't know if higher amp battery chargers are available, but I don't feel like spending extra money on one.
As far as battery health goes, charging at a lower amperage certainly isn't hurting the battery. If anything, it's actually better for it.
Yes...charging just the battery with wall charger.
@ 40% it will not be charged at 6am when I wake!!!
Are there better wall chargers?
Why do you hate having your phone attached to a Cord overnight. I heard that's fine and do it every night.!

Not for the phone, for me. It just bothers me having a wireless device locked to a wall. There's no reason for it. And I frequently get up in the night for various reasons (kids, work, insomnia, etc), and it bugs me unplugging in the middle of a charge cycle.
Incidentally, a non-removable battery was a deal breaker, and one of the reasons I didn't get a Nexus 4. I got used to never plugging in my last phone, and I don't want to go back. It was torture the first week or two with the N2 before my spare batteries arrived.
The charger should have its output printed on it, I've had a look at the pics on ebay and the first two I found that I could read were 500mA and 350mA, the original charger is 2A or 2000mA. Samsung make there own battery charger http://www.samsung.com/au/consumer/...es/EB-H1J9VNEGSTD?subsubtype=other-multimedia the output is 1.7A so much closer to the original usb charger.
I'd be worried about my back cover getting loose doing what you do. I had three batteries for my old phone, but I did not swap them on a daily basis, just when travelling or away from power for an extended time. I've ordered some wireless chargers so I can have one by my bed and another downstairs. I know they only output 500mA too, but for an overnight charge thats fine for me. I dont think there is any issue with interrupting the charge cycle, the two main enemies of lithium batteries are heat and being totally/almost discharged on a regular basis. Its best to keep them topped up.

The charger should have its output printed on it, I've had a look at the pics on ebay and the first two I found that I could read were 500mA and 350mA, the original charger is 2A or 2000mA. Samsung make there own battery charger http://www.samsung.com/au/consumer/...es/EB-H1J9VNEGSTD?subsubtype=other-multimedia the output is 1.7A so much closer to the original usb charger.

It looks like the OEM battery charger is available on ebay for around $15. That's good to know in case mine ever crap out on me. These cheapies that I get tend to.
As far as the back cover getting loose, after 3 months, it is a little bit looser than when it was new. 1.5 years with my G2x didn't loosen it at all, but the build quality on that thing was fantastic. I keep this in a case anyway, so it being a little looser goes unnoticed. If it gets bad, back cover replacements are cheap.
If one of the devs can make the kernel capable of fastcharge, it would not take but half the time to charge. Yank who is working with Faux on his kernel, helped make the kernel fast charge capable.

But what is the point of having it charge fast, when all it is is going to drain faster?
I charge mine overnight with a charger rated at 750mah I believe and it last me a whole day. As oppose to using a 2.1 am charger I have, where the battery percentage would start dropping by the first hour.
Correct me if I am wrong here, but this is what I've notice with my last few phones.
The Perseus kernel with stweaks has the ability to change the charging parameters.
With it overclocked/undervolted I am getting better life than I did on stock.
Not for sure what you mean as it depleting the charge faster on a higher amperage charger. Kind of sounds like you may have had failing batteries, etc.
There seem to be a few misunderstandings here regarding batteries and chargers.
1) The charge rate, when the battery is in the phone, is controlled BY the phone. The charger itself just supplies regulated power to the phone. How much current is put into the battery at any given time is up to the phone, which is why kernels can do things like fast charge, it's controlled by the kernel. Now, the reason the battery charges faster when using the stock charger vs. something lower current or a computer is simple. The phone can detect what it's connected to within some limitations. It sounds like our phone can also sense the incoming voltage levels and back off if the supply becomes unstable.
2) Using the stock 2A charger is "harder" on the battery than a lower current charger. Not true, at least not within any margin of error you will be able to detect without specialized equipment. Lipo batteries are generally built to charge/discharge at 1C. C in this case stands for capacity. So our 3100mah batteries can charge at 3.1Amp and be within safety margin. So the 2Amp charger the phone comes with is perfectly fine for the battery. Without seeing a datasheet for the battery from Samsung, that's a good guess. And again, the phone controls the charge current based on a number of parameters. You could connect the phone to a 5V supply capable of 100Amp and it will still only use what it needs.
3) The percentage readout on the phone screen is a GUESS. Don't pay it too much attention. For this same reason, evaluating 3rd party batteries based on phone runtime etc is not useful. To validate the battery capacity with any accuracy requires a test setup discharging the battery through a known load and measuring how long it takes to get to a cutoff voltage. I've done some of these tests myself on stock and 3rd party batteries. In general, the OEM batteries are always at or above spec, the 3rd party battery manufacturers lie. Often by upward of 20%. Even the high $ batteries. Keep that in mind when shopping if you want extras or extended batteries.
4) Interrupting the charge cycle is bad. Nope. It's fine. On this same line of thought, full cycles ARE bad. Don't do it. Don't think too much about it either though. Just plug it in when convenient. Or set it on the wireless charger if you've installed one. Generally speaking, they actually don't like to be charged to 100% either. Keeping it at 20%-80% is actually best for the longevity of the battery cell itself. In practice, you will probably have a new phone before any of this is actually noticeable.
The OP sounds like they are talking about a stand-alone charger, where the battery is not in the phone. Those will vary wildly in quality and capability, particularly from ebay. They are probably cheap POS devices. Not that that's really a bad thing, just know about it. It's probably a very low charge rate device, perhaps even down to 100ma or so. That would take forever to charge our larger batteries. As for if there is a better one, probably. If Samsung makes one, it will probably charge faster than the phone with the provided charger plug as there would be no load from the phone using power. Of course, it will cost a lot more as well. Look for devices that at least claim they will charge at 2Amp or so. In practice, they will probably be a lot lower, but your chances are improved. Not many people will break out an ammeter and check, after all.

Perseus kernal has fast charging settings.
What ttabbal wrote is mostly correct. But the problem lies within some input voltage protection logic tied to the charger chip of the phone which is extremely (and too much so) sensitive.

Can people stop calling it fast-charge, it's an idiotic term which technically means nothing. While most kernels have some sort of charging speed configuration options, they're all useless in regard to this problem as the current in the end is decided by a different logic. You'll have to disable unstable power detection and that's the only way to make it work and fix the problem, unless you go hunting down high quality cables and chargers.
Personally I also encountered the problem as my stock S3 charger, as many others here have reported, has deteriorated and it would only charge at an effective 300mA. I disabled unstable power detection and now it charges at the full given current limits, without any issues.

Charges faster in phone...while using!
If battery is around 40% it being be charged overnight.
Anyone else experience this?

You have to make sure it's "2a" charger capacity. It happened to me once. Go to monoprice.com and search for a universal 2a charger... pretty cheap
So now that samsung decided to remove the battery, it would only make sense to have a portable battery pack handy.
A friend of mine let me borrow his RAVPower 15,000mAh power pack and i have been testing it on my S4 to see how well it works, so far i am impressed with it, but i've only charged the phone twice, trying to see how many charges i can get out of it. will update this thread and post a better review of it later when i get better impressions of it. i also have an brand new Anker power pack i will be testing later on. primarily interested in charge speed rather than charge cycles. will update this post a bit later with more information and power packs.

I found this article linked in another thread over at Android Central http://www.phonearena.com/news/Doub...honeSuits-snap-on-Flex-Pocket-Charger_id66907 and this is a nice pocketable charger that doesn't require you to have a cable on hand to charge.
Here is PhoneSuits page http://www.phonesuit.com/phonesuit-...-smartphones?gclid=CJ35qJvdk8QCFRMatAod43cAAg and its listed at $49.95.
that's quite a bit of money for only 2600mAh, guess it's small so that is a plus, but if you want something that can charge several phones with one charge i would go with something like this:
http://www.amazon.com/gp/product/B00NWEB49W/
it even doubles up as an actual wall charger.
smaller than a pack of cigarettes and a bit cheaper than that 2600mAh power pack.
I have this one. It's 10,000 mah, which is pretty good for the price.
http://www.amazon.com/TechMatte®-10...UTF8&qid=1426265278&sr=1-3&keywords=powerbank
It takes about two hours to charge, and then to charge my dead s5 takes about 1 hr and 45 minutes.
I have a Samsung one with 10000mAh and it is pretty good. With a 2000-3000mAh you are not even going to charge the phone up once, so pretty much useless.
I have been using Anker 2nd gen Astro2 for a year now , looks good with plenty of juice , and as per manufacture specs it can push out 3 Amps , 3 Amps is useless on my S4 but it should be perfect for S6.

forget finding a "fast charge" on portable chargers. highly unlikely you will find one. maybe in the future when someone figures out and implement some kind of voltage step-up regulator as it's a limitation right now since to get fast charge to work you need 9 Volt output and current portable chargers can only output @ 5 volts. it's basically a limitation on the internal li-ion batteries, they can only output 4-5V.
your best bet is to get something like the Anker 16,000mAh for high capacity and pretty fast charging, it can output 5V at 2.1A, it will charge most phones (Galaxy S4, S5) in about 1 and 1/2 hours from about 8% battery left on the phone. you might only shave off only 15-20 minutes using a samsung wall fast charger, so it's really not a whole lot difference..
Anker 16,000mAh 2nd gen:
http://www.amazon.com/gp/product/B00N2T7U90/
it will charge an S4 or S5 roughly 5 times with a single charge.

I have already got that power bank..thnx any ways
Sent from my D6503 using XDA Free mobile app
I've a TP-link 10400MAH, it's very good
i got the mi powerbank 10400mAh, its charging my lg g3 quite fast (output rated 2A).
never looked how long exactly it takes, but i will do that when i get my edge.
it's using standard lithium cells from samsung/lg.
i think it's also possible to change them, have to investigate this.
