I would like to find out how long would this pack last with eneloop battery's.
anyone have any idea?
also if it would be possible to build or find a external battery that can take 8AA battery's.
Eneloop AAs are rated 2,000 mAh?
my rough guesstimate, you'll get about 4x your normal stock battery life from the pack, after you factor in losses from heat and from converting the pack's juice into your cell battery.
maybe a little more?
whats the total mah for the pack if i put in 2000mah batteries? 10 000mAh?
RAVPower rp-pb03 external battery
I own one before, it is really charge my HTC EVO 4G with bad result. I only use the device once before it basically melted. For reference, I used Sanyo Eneloop batteries in the charger and I used the retractable cable provided with the mini usb adapter. The charger did recharge my batteries, but it got so hot when charging my phone that the outer case warped from overheating. So I ask to replacement, however, the second one I received got the same problem. Also the charging speed is very slow.
I bought another RAVPower rp-pb03 external battery on Amazon one month ago. Since now the battery works very great. I love this device! Not only does it have a very handy flashlight, but it never leaves you guessing how much power is left. It works with my phone, my wife's phone and both of our tablets (all different brands!) The size is nice and compact, and I like the robust weight. It's easy to use, and compatible with everything I've tried! This is by far the BEST accessory I've bought for my electronics by far!

it look like it can be a good Accessorie for the desire but I can't find one like this for the Desire
since you are from israel.... you have got some kind of Energizer power pack it cost around 100 nis but it is not a good looking one but it is use-full
HI
Don't Know if it's still relevant but I bought PortaPow external battery charger, with 3000mah capacity. They also have cases that charge the phone, even with solar power - I loved them a lot.
A bit more expensive, but worth it in my opinion.

looks usefull !
thanx for the link
I just ordered mine, it should recharge my Desire 3 times.

One thing you guys might be overlooking is that the sated capacity for most of these power packs is at the batteries 3.7v. The unit then has to turn the 3.7v to 5.5v which will mean the actually mah you will get out of the device to your phone will be lower.
Still useful though if your battery dies!

Im in the process of making something simular, it wont be pretty but it will do the job.
I have ordered a 4x "C" Cell battery holder, that I will wire to a USB cable.
I have a few C Cell 3000mAh rechargables @1.2v each.
1.2x4=4.8V. I figure, this should be close enough to provide power into the desire.
It wont be pretty, but it should charge the battery of the phone a few times when im out for a few days
Total cost will be way less than the cost of the ones you buy.
Thanks for the links. Still deciding which one to get. Anyone have any experiences with the above?
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

Well for the first, people get extra batteries so that when the first one dies(OEM Samsung battery that came with the phone) they can just pop in the new one by anker etc. And keep on chugging without charging. Hope that helps. Also, after so many charges the OEM battery loses some of its MaH amps so people will purchase a cheaper(anker tends to be about 10-20 bucks less) to replace it. Price is always a deciding factor to most consumers, especially phone owners.

I get extras because I hate charging my phone. When one dies I pop in a fresh one and go. I am getting two ankers Monday so ill have three batteries.

From Note 2 experience, Anker OEM replacement battery performed and lasted longer than Samsung battery. Period! Plus, as some others pointed out, you can use external charger to juice it up, and just swap batteries on the go.
For external battery banks, Anker is also the way to go. Go to my Review Link in the signature where I have reviewed and posted detailed write up for close to a dozen of power banks. 6000 mAh is a thing from the past. Right now new power banks have 10,000 to 15,000 mAh of capacity in the same footprint as old one. Plus keep in mind, the actual capacity of external charger will be 30% due to usb port conversion (going from internal cell of power bank 3.8V to 5V usb port, and back to 3.8V on your phone through usb port - close to 30% loss due to efficiency).
Yes that 6000 mah power bank will give you only 1 full charge, and the charging speed is equivalent to USB. If you are doing NAV or some other heavy power draw, the external battery may not keep up.
And if I have to carry a spare, the internal battery is smaller and I know exactly what I am going to get in terms of performance
im finding that the anker 2600 batteries i bought are better than my two samsung batteries. i have two samsung batteries because 1 came with my phone and 1 came with the brand new insurance replacement after i smashed that phone. pretty happy with anker. no need to add bulk to the phone with an extended. just keep a spare battery when needed. i have 1 in my camera bag, 1 in my backpack i take to work, and 1 i can slide into my wallet if it's just me and the phone.
I bought Anker 2600 dual battery and external charger pack. Love it. Been using it and swapping batteries out every morning instead of being tied to a charger. Good for trips where I make heavy use of Cell phone to watch videos and such.
Had one issue. the internal connector that the pins that connect to the battery kinda broke on mine. The piece the pins are attached to fell inside the charger case. No problem though just opened it up and hot glued it back in place. All that keeps it there from the factory is glue and mine just came undone. Happened while traveling with charger in a bag with a battery in it, possible something pushed it hard.
Good to know that 2600 anker is better than actual battery... I was planning to get the 3k zero lemon but every one suggests is not doing much difference

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.

Do you have screen on time and standby time for the anker battery?
I received a RavPower 3000 lipstick charger. Think it performs quite similar as yours. I love that they have a luster gold color, it matches perfectly with an iPhone 5S.
Hi all, so I've got an S4 and the battery just doesn't do it for me as I'm quite a power user. So I've been looking into various methods of keeping my phone's battery topped up, especially on the go, I've had a look at portable chargers, external battery cases (as I had one on my S3 and it worked great, for about a week and then gave up) and extended batteries.
Now what I'm looking for is ideally something that isn't too bulky, has decent quality and provides a good solid charge to my phone. I also have a bunch of other phones that I want to keep charged, so an external battery case or extended batteries are looking a little weak here as a portable charger would do the trick for all of them, but then again they often seem to be quite bulky.
So my question to you is what would you advice? Ideally I'd like a solution that fits in the pocket and still keeps my phone topped, what would you recommend and have you bought something to satisfy this need yourself? I'm not really looking into extended batteries that add a whole lot of bulk, I'm hearing good things about Anker batteries and these 3,000mAh Zerolemon standard size batteries, but there seem to be so many variations of portable chargers I'm not quite sure what to do. Any help would be greatly appreciated!

I have the Zerolemon battery, it works well, but really, I couldn't tell much of a difference in battery life, and keep in mind, NFC is not included if you go with the Zerolemon.
Go to amazon and do a search for "android portable battery charger" there are a lot of options from small lipstick sized charges to big bulky ones, read the reviews and pick one that works best for you. Personally I am usually close to a charger so I have not found the need to get one yet, but I can see how it would be necessary for those that are frequently away from a wall outlet or car for extended periods. I might pick one up before my camping/float trip coming up this summer. If I did, it would probably be this one. http://www.amazon.com/KMAX-806-Flas...8-5&keywords=android+portable+battery+charger
I have an old external charger that came with a 3 panel solar folder. I used it a few times when camping and I could charge it all day and then use it to charge the phone twice. That was with an older 1900mah batter in the phone
Just a quick update, I eventually decided to settle with this EasyAcc iChoc 5,000mAh portable charger. I've had it for a few days now and it works fantastic, the build quality feels nice in the hand and the dimensions are the same as my S4 (and just as slim mind) it comes with two outputs, a 1A and a 2.1A one (using your own microUSB cable) and the 1A output has a built in microUSB cable. Very pleased with the purchase, it was around £17 on Amazon Prime:

Bear in mind I don't think the actual capacity is anywhere near 5,000 mAh however.
Charges S4 about 1.3 times.... So it's about a 3000mAh

Are you referring to the EasyAcc portable battery that I posted?
While I think you have made your choice .... I have used the callpod dou charger.... I had 10 of them until I started giving them away cause they were of no use with the phone I had before I got my S4. I have (5) Isound 16,000's 16,000 mah. That will keep my S4 or my wife's Iphone 5 up for about a day of intermittent use.... she can kill one in about 8hrs if she is on her phone and charging her Ipad at the same time. I also have (3) of the power bank 33,000s . 33,000 mah. I am not sure that I have ever killed this battery with my S4 alone. My wife can kill it with her iphone in 2-3 evenings of fairly constant use.... talking on the phone and playing games and I think charging both her iphone and ipad... (flipping back and forth between the 2. This battery will also charge most laptops. Her Macbook will get one full charge out of it.... if the computer is not on. With the computer on it last about 30-40 mins. My Htc Flyer has been on a 33,000 all week with off and on use and is still half full. Finally , I have a hyperjuice 150wh and a 222wh. The wife has been charging her iphone on the 150 and her ipad on the 222 all week and they are still around half full.
I finally got myself the Anker 5200 mAh battery. Does anyone know an app that shows the correct battery capacity? I got the sneaking suspicion that it isn't detected properly...
