[Q] External Battery

http://tinyurl.com/2wmzn39
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!

[Q] Did any one see Rechargeable External Battery Pack for Desire?

I find that iphone have an 2000mAh Rechargeable External Battery Pack that atached like a silicone case mix with car docking in Dealextreme see the link:
http://www.dealextreme.com/p/2000ma...ack-for-all-ipod-iphone-2g-3g-3gs-black-32202
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?

Battery Charger Set

Lots of posts with good spare batteries.
Here's one more to consider that I picked up on ebay for $12!!! It shipped free from China & I had it in 8 days. It's gone up now to $19 but to have an extra is always great for plane travel, etc... The set comes with 3 1600mAh batteries & a wall/usb charger. Charger is pretty nice, has a large LED indicator on the bottom that changes color when charged.

I got the same ones for my HD2. I ended up buying the pack with a charger and 2 batteries twice, I did end up loosing my offical battery one day so I am now running off 4 of these batteries. I haven't had my phone plugged in for ages.
The batteries seem to work just as well as the OEM one. As soon as I get my sensation in the post these will be the first accessory I'll be buying.

820 spare battery and standalone battery charger options

I'm looking for cheap 820 spare batteries and a standalone battery charger. Understandably, this is a new phone and folks can't expect a lot of accessories to be on the market yet, but I figured we could have a thread to track the options.
For the Samsung Focus we were satisfied with generic batteries and chargers like this one:
http://www.amazon.com/Batteries-GT-...sr=8-1&keywords=samsung+focus+battery+charger
These batteries are still working OK after a year of use although they only last about 80% as long as the name brand batteries and according to our kitchen scale weigh a few grams less. The charger just cut out and fails to charge after a solid year of daily use. I opened it up planning to diagnose with the multimeter, but never got around to fixing it. Really though for $13 it wasn't bad for 2 working spare batteries. So I'm looking for something similar for the 820.

+1 for this, I am also looking for something same. Got it for my old HD2 and I bought the Lumnia 820, because of you can change the battery and extend your memory with the microSDHC Card.
We will see what time will bring us on extensions for the device. I think its to new at the moment.

Same again...looking for a spare battery for the Lumia 820
Infinidim

I will also be looking for to purchase one regardless of how difficult to remove the caseback.

Universal cell/camera Li-ion battery charger
Has anyone used one of these universal chargers that allows you to move the charging pins to fit any battery?
http://search.accessorygeeks.com/search?query=universal+battery+charger
Might be a good option.
AT&T still has the best shipped price for replacement batteries in the USA:
http://www.att.com/shop/wireless/accessories/batteries/sku6320370.html
Even if the site still shows a Samsung Focus-S battery

http://www.newegg.com/Product/Product.aspx?Item=9SIA07Y0K09316
Best price I can find from a brand I suppose I can trust. After all, it is sold on Newegg. $9.99 with free shipping
I want it because I it says it is a Li-Ion as opposed to the stock Li-Po battery. For some reason I just don't trust Li-Po batteries.

I've used an external charger with adjusting pins for about a year. Radio shack sells them. It's not the best quality but as long as you don't drop it, its all good. No complaints other then the price. But locally their not easy to find.

can i buy one with larger capacity?

The EZO power one I posted earlier is 100 mAh more at 1750mAh. I haven't used it very long, so I don't know if it lasts any longer..
http://www.newegg.com/Product/Product.aspx?Item=9SIA07Y0K09316
Also, there is a Mugen Power one for $45. It is 150mAh more at 1800mAh total.

The EZO battery is $6 shipped at Amazon 3rd party vendor Bluemall:
http://www.amazon.com/EZOPower-Standard-Lithium-Ion-Replacement-Battery/dp/B00B905GOK
Bluemall has pretty good reviews as an Amazon vendor too

I don't think the battery is that good... It lasts okay, not as well as stock battery

NON OEM Battery x2 for $17

or
2X 1700ma battery with stand alone charger for $18
http://www.amazon.com/Onite-1700mAh...950&sr=1-5&keywords=lumia+810+battery+charger

I don't understand why Nokia puts such low capacity battery... With these dimensions it should be about 2000mAh, just like in 720... Maybe small petition to Nokia or sth?

I can use my lumia 820 battery for 2 movies and 3 tv series. And it last long. so 1750 mAH is enough

We got the EZO battery and the cheap universal clamp charger from amazon as well. It works, but it doesn't last nearly as long as the OEM battery and the charger takes quite a long time to fully charge the battery. For $6 it ain't bad though.

I tried the ezo battery, and it actually lasted longer than the original battery, when it worked. I may have gotten a bad one though because it just started dumping its full charge all at once, and my phone would just die after about 3 or so hours.

Portable chargers, external battery cases, extended batteries etc etc

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...
