I like a lot of people use my phone very heavily yet I don't have an opportunity to plug my phone into an AC charger until I return home. A great remedy to the problem is this handly little AA charger.
http://www.igo.com/accessories/powerxtender-charger/invt/ps002640004/
The reason I like it so much is because cheap portable battery packs usually pack under 1000mah of power. Thats not even enough to give you 1 full charge. And the more expensive 2000mah+ packs are often on the large side and well... expensive lol. On the other hand this little bugger is cheap and small enough to sit in my pocket without being a bother. What I find is the best part of it is the fact that you can choose what kind of AA batteries you put into it. I opted for Energizer rechargeable which are rated at 2450mah EACH for a total of 4900mah of power. Thats the equivalent of 3 G2x batteries. Keep 2 more batteries in your backpack/desk/purse thats an additional 4900mah. If that can't get you through the day you have more than just phone issues
Originally bought it for my Vibrant but quickly found it was awkward because the the product doesnt come with a cable adapter. This meant it was hanging and putting much strain on the usb port of the phone. Out of fear of breaking it I stopped using it. However since the G2x charges from the bottom there is absolutely no problem espcially seeing as I bought a 20cm micro usb extension cable so that the charger can sit in my lap or on a table while using the phone.
Just thought I'd share this since we can't get legit replacement batteries yet and even when they do become available they will cost a pretty penny. Got mine from Staples but they can be had on amazon also along with the usb extension able and rechargeable batteries.
This one works very well, too:

You don't need to by batteries or an extra charger. You can recharge it via your G2x power supply or any computer.
This was my favorite (coming from g1)
Too bad theres no new version for the micro usb's now..

This can be added on, though it wouldn't be very convenient since its a slide in/out connector

I almost bought one of those until I saw how low the capacity on it is. Looks tiny though which is nice.
J&R has Veho 5Ah external battery for $35 and I have 2 of them.
Just use regular microUSB cable to charge the phone and leave the original cable secure.
I'm thinking about getting the i-up 13,200mAh pack.

They have a bigger version for 32$ as well. The 22$ version gives me a full charge from around 30%.
Just received my Pebble XT 5000mah pack. Won't be able to put it through its paces till next tuesday. Upon first impression, i think im in love with this thing already. its small enough to sit in pocket without having much presence. extremely lightweight. and the cord is long enough to be able to have the charger in your pocket and phone in hand (thank you lg for putting the usb port at the bottom). All info I have read indicated that it really does output 5000mAh of power so even a heavy user such as myself will have no problem getting through a full day of use.
Just wondering how everyone's batterys are working out for them?
Also how many full charges did you get?
Also any likes or dislikes of product they decided to buy?

That looks like something that might be good out camping or something where you needed to charge your phone without touching it. But I would figure actually picking it up and putting that much weight on he usb port a very bad idea... This should come with a extension cord to charge while using, even texting or something would be pretty difficult to hold both...

ImaxPower IMP500 (5000mAh) External Battery
I've used an IMP500 Rechargeable (5000mAh) external battery pack for a few years with great sucess. They make them as large as 11000mAh (or more?) and even have solar-rechargeable options. Just take a look at New Trent or other similar products on Amazon or eBay.
The best part about the IMP series is that they have multiple adapters for iPhones, mini/micro USB, PSP, DS, and other devices so you can charge your phone and anything else you might be carrying around with you.
Link to NewTrent for info on models
I'd recommend buying elsewhere because you can find them for 30-50%+ off.
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

Dear XDA, i really need your help,
I am planning to make this (see thubnail)
i want to make a custom case for my htc one s. (I know it will be a little bigger but that's ok)
I want to charge my phone using a usb cable or a micro usb cable, and at the same time doing OTG. I don't know what resistor i will use yet (tips?)
Also add an extra battery. It is an old phone battery. So if i want to charge from the battery i need to stop the solar cell and guide the electricity through the 5v regulator to charge. What ya think?
I am new to modding so please comment cause i need a lot of help to make this one succeed!
Greetings, pro-one1000

Don't mean to be negative but I see a couple issues right of the bat. First, where are you going to get a 5 volt charger? I would guess most dc chargers are going to be 12, 24, or 36 volts. I don't think they'll run on significantly less. The solar panel is only going to output about one half of one watt. Assuming no friction loss or inefficiencies that would hardly slow your phone's discharge.
If you want to power the phone and hub I would suggest a small sealed lead acid battery. They're available in 12 volts in many sizes. Easily enough power to keep phone totally charged. Will work with cigarette lighter car chargers so you won't need to customize that part. Depending on the size it'll last a week to a month non-stop. Unfortunately, it probably won't fit in your pocket but if you carry a book bag or briefcase you could hide it there... I use a battery like this at work when I'm using a lot of phone battery and moving around too much to plug in.
Good luck with which ever route you choose!

Thanks for your reply!
First about the charger, i will use my 5v 1amp charger (micro usb) or an usb male to male usb cable from my pc to charge. So i'll be able to get a charger.
You're i think right about the solar panel, i need to find a better one indeed, trying to get one cheap on ebay! If i try to search for a "smal sealed lead acid battery" i get 40 dollar + big cases of batteries, could you please give a example in the form of an ebay-link?
Anyway thanks a lot and when i have ordered the parts i will try to upload the stuff!
Greetings
I'm assuming the 5v charger you're talking about it a car charger; which means it would have an input voltage of 12 - 14 and won't run on 3.7 (and even if it could run on the lower voltage the amperage would go up dramatically draining the usable power in the battery in minutes. And I wouldn't connect anything to a USB port for two reasons: first, if you connect two batteries in parallel (red to red and black to black) and they're not identical one will usually drain the other as they try and equalize (unless you isolate them from each other). Second, I don't think most USB ports (USB 3.0 i believe has provisions to receive power) are designed to receive power on a computer and your schematic doesn't include anything to prevent back feeding power to the computer.
There are many solar chargers I've seen that would give you the output you need - I've seen them designed to trickle charge RVs, boats, cars, and motorcycles - but I think they would be way to larger for what your looking for.
And I guess I should clarify what I meant by small... Was a bad choice of words for a cell phone forum, I guess. I meant small relative to other lead acid batteries; i.e. car or boat batteries. This is similiar to what I use:
http://www.ebay.com/itm/12VOLT-5AMP...US_Rechargeable_Batteries&hash=item589ef11aed
Attached is a pic of my batteries and the adapter that gives me a cigarette lighter type receptacle. And I use a spare motorcycle float charger to keep them charged. And because they're 12 volt batteries they'll power and accessory that is designed to run in a car.
I guess I should probably have asked what is your ultimate goal? And do you carry anything where you could stash the battery?

Thanks for your reply,
After thinking I want to use a second1-5 volt boost regulator attached a small high capicity battery of 3.7 volt. (like a galaxy sIII battery or something. So if i put the switch to on the extra battery should charge with 5v my phone battery. Or i could charge my phone directly from a high efficient solar cell with 5v.
I indeed have no idea how to prevent backfleeding. Do I need diodes / light emmitting diodes for this? And indeed the batteries you mentioned are way to big. I am planning to use an old battery from an other phone with the 5v boost regulator mentioned above. Further i don't understand where you see a computer in my scheme?
Your mod ( i think i it deserves that wonderfull name) with the 12v battery is a good idea. Very handy when going out without a charge point. I usually go to school and am probably able to put the large battery in there, but as i mentioned i want to keep it a "phone case".
My ultimate goal is to make the tiniest possible case for the htc one s ville with,
- a very small usb hub 4 port for 3 female ports and inside a micro sdhc memory for more storage.
- Add the charge ability, so i don't need to take the phone out of the case to charge
- be in otg mode and charging mode at the same time (i guess the hardest challenge)
optionary:
- Add a battery so when i get the actual phone out of the case the solar cell can keep providing power to the battery
- Add a solar cell
- make it actual work with multiple switches
Really appreciate your help!
Greetings,
I misunderstood "First about the charger, i will use my 5v 1amp charger (micro usb) or an usb male to male usb cable from my pc to charge" to mean you might have a computer available to charge. I guess you just meant the cable itself. Understood.
I'm not an electronics expert by any means but yes I believe diodes will prevent the current from flowing in an undesirable direction but they won't prevent one battery from draining another. Two batteries connected in parallel can drain each other and the diode will slow that but I don't think it will eliminate it. Might be able to mitigate the affect by opening one of your switches when the auxiliary battery is not in use. When two batteries are wired in parallel they are frequently connected to an isolator that has three terminals (for a two battery setup). Terminals one and two go to batteries one and two and terminal three goes to the system it's connected to. Batteries one and two never 'see' each other and therefore cannot affect or drain each other.
Not sure I have anything else that can really help... GOOD LUCK! And post pics and details if you build a working prototype.
Thanks again!
I'll try to order a couple extra diodes with low consuption, that plus the switches will hopefully do the job. I ordered yesterday the parts out of China, so it'll take a month to get it in my hands. Now I have more time to consider how it can be assembled all together, but if i get anything i will post it directly!! If it works i may try to make a tutorial for other people so they could also enjoy more ports on their phone!
Greetings
does anyone know of a really good but cheap external battery
rather get that than a extended battery because of (cases)
Take a look at this one: http://www.amazon.com/RAVPower®-Dynamo-On-RP-PB07-Flashlight-originally/dp/B009V5X1CE
So far this is the most compact and most capacity external battery I have seen. I personally got one and I'm loving it so far (the reviews clearly say everything you need to know). You can even charge tablets with it as the charge on it is seen as full AC (capable of 2A+) and not regular USB (limited to 500mA).

i think thats the one i might get!
So, I am a Note 4 owner. I have a 128GB microSD and 3 extra batteries.
I like the fact that I don’t have to be like my iPhone using friends that are always looking for a charge when they stop by. I easily carry an extra battery in my jeans pocket, and in the middle of the day, refresh my phone with a new battery. Two easily last me for a full day with non stop use of my phone.
Additionally, I am a big fan of the microSD. Since the Note 4 isn’t USB3, the transfer rates when I plug the phone into my computer is suuuuuuuuuuper slow. So I just transfer anything I want to take off the phone onto the memory card, and plug that into a USB3 reader on my computer and get adequate speeds. I have started using the AC wifi for transfers a lot more, but I also have a Tab S 10.5, so I use the microSD swap when I’m out and about and want to continue watching the movie on a smaller/larger screen.
So the new Note 5 doesn’t have a microSD port, changeable battery, or USB-C. So I am trying to figure out how I could use the phone on a day to day basis without having issues. And I have come up with a solution. But I don’t think it exists yet. Which is why I am asking you guys if you have seen this (or maybe a hardware vendor will see this and make it themselves)?
What I want/need, is a power pack that plugs into the bottom of the phone. The specs:
• Utilizes Fast Charging/Quick Charge 2.0, so it will charge the phone in 30-60 min
• Small so I can fit it in my jeans pocket
• Has a MicroSD port so I can transfer files while it charges
They already have an external battery and microSD case for the S6 http://www.androidcentral.com/incip...g-microsd-card-and-external-battery-galaxy-s6, but I don’t want to have to carry a spare battery in my hand all the time. And they have microSD battery packs that will charge and transfer to your phone, but they are slow to charge and to large for the pocket http://www.amazon.com/Kingston-Digital-Companion-Expanded-MLWG2/dp/B00KU2E9IW/ref=sr_1_17. And they have powerpacks that plug directly into the bottom of the phone but they charge slow and have no microSD http://www.amazon.com/PNY-DCM2200-2200mAh-PowerPack-built/dp/B00LCAFPAW/. And they have Quick Charge 2.0 battery packs http://www.amazon.com/Qualcomm-Certified-Aukey-10400mAh-Supported/dp/B00UBDI7EC. But nothing with all 3 things that I want.
Any ideas? I think this will stop a lot of people who are saying they will jump ship when the Note 5 comes out. It will address people's need for a spare battery and access to a MicroSD. For people with a large movie/music collection, they can transfer what they need, when they need it. And for people that like the security of an extra battery, they will have the next best thing (if they go on extended trips, then they can get a larger battery pack).

I have the best idea, just stick with the note 4, the 5 seems like taking a step back.
Incipio has one with battery and micro sd slot for the s6, might do one for the note 5.
