hello.
is it correct that the anker extended battery for the s4, should be showing a capcity of 2600mah in battery monitor pro?
is it because it is 2 x 2600 batteries joined together?
bit confused.
To my knowledge battery Mon pro won't be able to automatically determine accurate capacity of the battery when you just plug it in. It has to calculate it through extended use by monitoring discharge rate, and even that is not accurate.
anker 5200
same as me,
i try using battery doctor or du battry saver but it's only show 2600 mah in system.
i wonder how to make it show 5200mah
just watch the voltage. You will know what it's got left by watching the voltage drop after a few days. The cheap apps are telling you 2600 because that's what the phone comes with. It's written in
Use Android Tuner or battery calibration on appstore, they give actual voltage
Any Doubble Power Battery ???
Six hours continuous use
Confirming my Anker 5200mAh Extended Battery provides six hours continuous use with my Galaxy S4.
Very happy with my purchase, and recommend the Hyperion HoneyComb TPU Extended Battery case for use with this extended battery.
how much do you know about external chargers

many external chargers especially ordinary chargers are oversized in capacity. though they may be very cheaper, they are usually shoddy and deceptive. i recommend you to read this article.
Don’t buy external battery before you read this!
As we have more and more gadgets, we are expecting our gadgets can always work when we need them. Our gadgets can do almost everything — until they run out of fuel. Times when you need to make that important call, send out an urgent e-mail, or need to use the apps on your device – but alas there is no battery…we’ve all been there and know first-hand the stress of being offline when you need to get things done!
External battery is indispensable for our smart life, but how much do you know about the external battery? Does your external battery really charge your gadget or make the damages to your battery of gadgets?
1) What’s external battery?
External battery serves as an ‘extra battery’ or external charger for your phone or other electronic devices.
2) Where is external battery made from?
Majority of the external batteries in the market are actually made in China. And the battery cells or PCB modules are from different countries.
3) How do I charge the external battery?
You can charge your external battery via the charger that came with your phone, computer usb port or using other external battery
4) How long do I need to charge the external battery?
It depends on the REAL CAPACITY of the external battery. The larger REAL CAPACITY, the longer charging time may required. Different charging methods may result in different charging time as well. Charging with the original charger will be faster than charging with computer usb port.
5) Why sometime I need longer time to charge the same external battery?
Even though using the same charging method, the charging time may be differ due to environment, temperature, power flow and etc.
6) What is mAh?
mAh mean milli Ampere Hour, the capacity of the external battery is measured with mAh
7) Is a 12000mAh REAL CAPACITY external battery, able to charge a 1500mAh capacity phone for 8 times full?
This is a common mistake made by most of people. For rough calculation of the total charge time, kindly use this formula
REAL CAPACITY * conversion rate * phone battery health / phone capacity = total charge times
EXAMPLE: 12000 x 0.8 x 0.8 / 1500 = 5.12 charge times (0.5-1 times plus minus)
8) What’s conversion rate?
Conversation rate is the remaining percentage of the battery after the battery loses in heat or PCB operation.
9) What’s phone battery health?
In simple, it means how ‘healthy’ your phone battery is. Phone battery storage capacity will be lower and lower. That’s also the reason why our phone can last longer when it’s newly bought than after 3-6 months of use. Different mobile phone models also will affect the calculation as some phones drain battery faster than others.
10) What’s PCB?
PCB means Printed Circuit Board, which controls all the operation flow inside the external battery. A good quality PCB will allow the external battery to charge more and have better durability
11) What’s the difference between 18650 and Li-Polymer in the external battery?
- 18650 size and dimension are fixed. Li-Polymer size and dimension are flexible.
- 18650 produces more heat. Li-Polymer is much safer
- 18650 is cheaper. Li-Polymer is more expensive
- 18650 has a higher self discharge rate. Li-Polymer has a very low self discharge rate
- 18650 battery capacity drops faster. Li-Polymer battery capacity is more durable
12) What’s the common REAL CAPACITY in 18650 external battery in the market?
- External battery using 1pcs 18650 is 1200mAh – 2600mAh
- External battery using 2pcs 18650 is 2500mAh – 4400mAh
- External battery using 3pcs 18650 is 3750mAh – 6600mAh
- External battery using 4pcs 18650 is 5200mAh – 8800mAh
- External battery using 5pcs 18650 is 6500mAh –11000mAh
- External battery using 6pcs 18650 is 7800mAh –13200mAh
- External battery using 7pcs 18650 (no info)
- External battery using 8pcs 18650 is 10400mAh –14400mAh
1 3) Is there any external battery with a capacity higher than 2200mAh per 18650?
Yes. There are, but it’s not common due to the expensive pricing.
14) What’s the difference between branded external battery and generic external battery?
Branded external battery is mostly sold in REAL CAPACITY. Generic external battery is mostly sold in MARKING CAPACITY. That’s the reason why you will never see any branded external battery (standard size) with a capacity as high as 30000mAh – 50000mAh. That’s also the reason why a good 12000-13000mAh external battery is able to charge more or almost the same as the market level of 30000-50000mAh. Most of the external batteries sold on amazon.com with low price are MARKING CAPACITY but not REAL CAPACITY. Those with higher price and long warranty(more than one year, some brands offer 18 months of warranty, like Sony, KINKOO, Xstorm) are REAL CAPACITY and reliable.
15) Is it true branded external battery won’t explode and generic external battery will explode?
Anything to do with battery will have a chance to explode. No matter it’s branded external battery or generic external battery. But chances for both branded and generic external battery to explode are very low, except for those cheap and poor-quality 18650 batteries. And the Li-Polymer is safer than 18650 battery, it’s easy to fit the high-temperature environment.

Has anyone tried any of the external battery solutions available out there? I've read that the Kensington one is good, but it's only like 1200-1400 mAh !
I've run across a few on Ebay that are running 4000-5000 mAh - great for multiple charges!
Anyone have any feedback on any of these?
I have used a few different ones over time. I currently have an Energizer pack with a 4000mAh capacity.
I recently saw a a 40,000mAh pack at Radio Shack for around $120. I almost bought it, just on general principles.
Anyway, yes, the portable packs do work well. But remember that the mAh capacity of the pack doesn't translate 1:1 to charging capacity. The battery in the pack is only a single 3.7v LiPo cell, and the battery in your phone is ALSO a single 3.7v LiPo cell. These packs use a switching regulator to boost the output voltage, which means that the cell will be discharged faster than you might think. If you want to fully charge the battery in the Triumph, you should try to find something with at least 2000mAh capacity.
One of the more interesting solutions I've seen at the Sprint store was an integrated charger. It had a USB jack, a short micro-USB cable, and an AC adapter all built-in. So you could basically use the thing as a USB wall charger, then unplug it and take it with you when you expect to need a little extra juice on the road.
Personally, I'd like to see more portable Lithium-based packs that can also put out 12v for larger devices. Ideally, I'd love to be able to power my phone and a portable speaker system all from a single battery pack. Perhaps someone will get smart and build a box to house and adapt the 2-cell rechargeable packs used by RC car enthusiasts...
I purchased a 1500mah Anker battery off Amazon for $15. Works great!! Much better than 1380mah stock battery

http://www.amazon.com/Anker-1500mAh...2?s=electronics&ie=UTF8&qid=1316908026&sr=1-2
anker do make external battery, i have one this ,5600mAh, very handy!
seems like have a 10$ off now, it's 39.99$! damn, i purchase with full price 49.99
Well I have came across many threads about Internal and external battery for Sensation and I know it's best to have an anker 1900mA or a Li-ion external battery.
However, I used 4 AA 2500 Ni-MH battery which can be found on Amazon: Eneloop XX 2500mA
I used a little device that can hold 4 AA battery and has a usb port which convert the voltage to ~5V and max current of 1A.
I wonder if it will damage my internal battery (currently HTC OEM) and will it give a good transfer of enegy between those battery compare with external li ion and internal li ion.
I know this is a complicated way to solve battery problem but I used to be iphone user so I cant change internal battery (which is crap), so suggestion of buying a new battery is appreciated but it will be more welcome if you can provide information that Im seeking.
Thanks for your time
External battery chargers are a tricky thing, how much capacity should we get? Our S4 have a 2600mah battery hence a 2600mah power bank should do the trick? FALSE. Read on.
The voltage of the power cells in the power banks are at 3.7v but the USB output is at 5V. This means that at 5V the equivalent capacity of the power cells are diminished due to the higher voltage. As a result, the effect "mah" of a power bank is usually <75% of what is mentioned due to the voltage difference. And this figure does not factor in the loss due to conversion. Most of the time, higher quality power banks would have a conversion efficiency of 90% but the cheaper quality power banks can have and a conversion rate of as low as 70%.
Another important fact about cheaper power banks is that they are often have a lower capacity internal power cells.
For easy reference and assuming a 70% conversion rate, get a power bank that is at least 2 times the stated capacity of your devices' battery and ideally you would only need to get a power bank that is 1.5 times the stated capacity.
Hence, if your s4 has a 2600mah, you'll have to get at least a 3900mah power bank and depending on the quality of the power bank it might have to be 5200mah
More math and physics will be included if required.
http://www.banggood.com/Teclast-T52A-5200mAh-Power-Bank-Charger-For-Tablet-IPhone-p-76746.html
This is a good choice. I've got a 10400mah and it is fantastic for charging my phone and tablet.
A huge plus is that apparently this chinese brand uses Samsung Battery cells which is good and it has a 90% conversion rate.
I posted something similar in the battery case thread below. That is why I just carry a spare battery. Half the size of an external pack and I get the full capacity.

Yeah but that's only as convenient when your case is easy to remove and put on.
A spare battery would be ideal for bumpers probably.

True, and you have to power down to make the switch. But the external batteries are not small, and you have to carry them around and leave your phone tethered to it when you use the phone.
When i have all my gear and i am traveling i have a 3000mah external battery in my backpack. When I am going out without a backpack and i am gone all day and need more juice, i through a spare phone battery in my pocket and i don't even notice it there.
13000mah battery
I personally got the limeade blast good price if you do the math vs other chargers, 2 usb ports and ledd light is usefull no to mention the monster 13000mah capacity,
Im struggling to believe that there is a 30% loss in conversion. I have a 3500mAh power bank and it charges my galaxy nexus almost 2 times. The galaxy nexus has a 1750mAh battery and the power bank completes 1 full charge and the 2nd charge reaches roughly 85%. There is some loss but it isnt as high as the ~30% stated here.

I like portable battery chargers. In addition to my ZeroLemon 7500mah battery, I also own a PowerGen 9000mah battery pack that has a 2A output port. I've been using it since last year when I got my S2 and it's very handy to have (although I don't use it anymore due to the ZeroLemon battery).

Like I said, it is up to 30% loss during conversion. It's also dependent on the quality of your power bank

Yeah, so far I am rather impressed with the Teclast power bank, I've used those cheap no-name power banks that you obtain from eBay and they are rubbish. The physical quality is good too which is also more than I can say for others. Do no buy solar panel equipped power banks, they are useless.
The battery capacity of my 10400mah power bank is really good though it's a pain to charge it up.
i have a naztech 10800mamp and a MyCharge Peak 6600mamp battery banks and prefer the naztech 10800mamp one with 5 usb ports all of which can charge at the same time. I can charge my 2 nexus 7 tablets and my 2 phones and a camera at the same time from this naztech powerbank and am happy with it. see my video comparison in my youtube uploads linked in my tag line. but i havent found the need for a battery bank yet with my S4 as am happy with the S4 internal battery for now.
I recently received the Anker Astro Mini 3000mAh External Battery for free from Anker in return for my open and honest feedback...so, here it is!
Anker Astro Mini 3000mAh External Battery
http://www.ianker.com/product/79AN3K-SA
The Astro Mini best served my purposes as I spent the last 2 weeks in the hospital visiting my brother. I used the Astro mini to recharge my completely discharged 0% Anker battery in my Galaxy S4.
Testing:
After extensive testing, I have determined that the Astro Mini provides roughly 1900mAh or 73% of a charge that makes it to the battery in the GS4. Anker states in the manual that 30% of the battery capacity is lost to heat and voltage conversion...which would effectively make the battery 2100mAh. I found this to be relatively accurate, given the fact that the GS4 can also lose some of the charge capacity through heat dissipation. It's within the realm of possibility that the GS4 wastes another 200mAh of capacity in the charging process.
My Verdict:
The Astro Mini is GREAT for use as an emergency backup battery! It consistently provides a 73% charge to my GS4. At $22 on Amazon, it's a great value as a quality external battery. It also comes with a short micro usb cable, a micro usb to Apple (up to 4S) adapter, and a quality bag to carry it all in. For my purposes, I choose to carry a backup battery in my pocket at all times. However, this external battery has come in quite handy on the few days at the hospital that I depleted both batteries and fits perfectly in my pocket in addition to my spare battery.
As a side note, I'd HIGHLY suggest that you purchase Anker replacement batteries for your GS4, as I did, as they most certainly outperform the Samsung factory batteries. NFC is fully functional with these replacement batteries as well.

Hello friends
I am using asus zenfone 6 which has a non removable battery
And back.up is not good at all..
Is it possible to have a extended battery pack for non removable battery as well ??
Thanks
I use a monoprice battery pack but there are definitely others with more charge out on the market - did you have a particular budget in mind?
@gossymer
is that a powerbank or external battery pack ? like zero lemon 1100mah battery pack for samsung galaxy s5?
It's an external battery charger than you use with a usb cord.
I carry a backpack anyway so I use it to charge my tablet and phone on the go. I prefer not to increase the weight of my phone directly since I spend a lot of time reading ebooks on it (2 to 4 hours a day) and that leads to hand fatigue
Edit: I tend to prefer heavier chargers that I can charge weekly instead of daily (10000+ MAH) but you can get really small lightweight ones that are 3000 MAH and comparable to the size of a lipstick.
