[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.

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?

Spare Battery Charger

Hey guys, g2x is on its way gonna be here monday. I know with my past devices like my hd2. The battery life was good but died after almost a day and close to night i would run out of battery. I thought it would be handy to have another battery to just pop in when my other was getting low so i didnt have to sit next to a charger. Im planning on getting an OEM battery as a spare.
So my question is, has anyone found a nice "spare battery" charger that you could charge just the battery without the phone? Like a cradle for it? or even a dock that holds the phone and the battery? Or have you had an positive experiences with any specific ones?
Thanks

Maybe this is what you're looking for.

You could also get a charger like this:

I bought one and it's great because any Li-Ion battery will charge in it. You just move the pins around to align properly. So I can use it with my camera batteries, Nexus One, Optimus One, etc.

Universal battery chargers - battery outside the phone while charging

Hi
I've ordered a new mugen 1950mAh battery and now I'm going to buy a new battery charger (not for the phone, only for battery). Here are some links such types of chargers:
Omg, I don't have 10 posts so I'm not able to post outside links. So please just write in 'images.google': "universal battery charger" and see the results. I take interest to the one which is a little bit similar to a computer mouse
Do you think it will work properly? Does anyone have got such a charger? Or maybe can you suggest sth other? I just want to use the phone with one battery, while the second one would be charged. Binding the phone to socket with cables during a day is very annoying.

No one? Can't believe..

not sure what you're referring to but http://www.amazon.com/Laza-Battery-Charger-Sensation-Shooter/dp/B0057HJU1Q is a good deal for 2 1700mah batteries and a standalone battery-specific charger. no pins to align every time. just slam the battery in and it goes.
or there's dozens of universal ones with sliding pins like http://www.amazon.com/Anker-Multi-Purpose-Universal-Battery-Charger/dp/B0058XGN7I
I'm sure you could find one of these for less than $5 shipped on ebay if not amazon.

But I've already ordered new mugen 1950mAh so I don't need to buy anything new. Mugen and stock batteries are enough
Unfortunately I can't find such a battery charger on ebay. But it's a cool thing because I would better buy something branded than some noname rubbish. Any ideas?

i'm using this: http://ioomobile.com/shopbybrand/990-momax-smart-battery-charger-for-htc-sensation-z710e.html
can use usb. but it only supply 500mA so it took longer to charge.

I've been using these for ages
These chargers are the best way to charge your battery, for me at least. I've been using them for years. Of course you need at least two batteries, but I usually have at least 3
These chargers are chinese creations. Some can be really slow, others a bit faster, but usually they give out around 200-400mAh which is kinda slow, but will charge your battery overnight.
The good thing about these chargers is when your phone dies or is about to die you just pop in the already charged battery and you are ready to go, no charger, no cables. And from my experience the battery lasts longer than if charged in the phone, sounds strange but it's true.
A downside is while charging they have this LED flashing, which indicate charging, and when they stop, battery charged. But these can be really bright and if you charge overnight in your room, you have this flashing colour changing lights.
I totally recommend these chargers. On chinese sites they go around 3-4$. Don't go for the cheapest, probably will be crappy.

Thanks for info guys. A week ago I bought YIBOYUAN 100-240V EU Universal Battery Charger USB Output F HTC Sensation/G14. Will see how it works

Hello
Battery charger i found is the Best

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...
