Trying to find gadgets of the type "external portable power".
That is power sources that is light enough to carry in a backpack or pocket, and have a battery (or in my dreams a fuel cell...) that can be plugged into SGS mini usb port for "emergency" power.
Also of interest is solar powered solutions, maybe to charge said portable power device while relaxing at the beach.
I believe this is what you are looking for:
spider-foot. com/1900mah-extended-backup-battery-power-charger-for-cell-phones-with-micro-usb-charging-port-1900mic-p-759.html
Ive seen a solar + wind up one as well, but not sure how good that would work.
There are few micro usb backup battery packs. Some are sealed rechargeable batteries (like the one in above post) while others allows you to use standard AA size ones (these are good in an emergency).
But IMO better to have a spare battery. That way you don’t have to wait for the phone to charge, you get instant power. Since SGS s batteries are very small you can even carry one in your pocket.
Personally I'd prefer something that used AA/AAA batteries. That way I can carry LSD batteries, and I can use a proper conditioner/analyser/charger on them to keep them in decent condition. It also means the phone doesn't need to get turned off at any point - I find mine isn't great after a restart for quite a while. Finally very high quality batteries are not that expensive for AA/AAA and you know what you're getting, aftermarket mobile batteries can be a little bit risky and performance can vary.
I use a solution from Philips, it is called Power2Go. I use the SCE4430. Works great, only thing is that it does not support micro usb out of the box. But a standard micro usb cable does the trick. Used this also on a Nintendo DS.

[Q] Solar Charger
Hey guys,
First post here and it may end up costing me a bit soo..
Would it be possible to harvest one of these solar phone chargers you see on ebay and build it into the backplate of the phone?
I know it may not be powerful enough to charge your phone, but maybe we can extend the life when we just need those few extra hours.
So, really, does anyone know what we would need? I have little to know electronics experience so not sure what i'm looking for but i'm more than willing to actually do it if someone is able to explain what/how its done.
No, it's enough for you to charge a phone, even other more powerful device. But first of all you need a good solar cell.
i got one from DX it works fantastic!
4200mAh Portable Dual-Panel Solar Power Battery Pack for Cell Phones and USB Gadgets
http://www.dealextreme.com/details.dx/sku.40210
just leave it by any window, or light source and it turns it back into energy, then just plug your phone into the pack for recharge
you can easily recharge twice with a full charge
red light = charging
no light = off
green light = in use
comes with all the plugs for our phones
and a build in LED flashlight
it can also be charged via USB if you are in a hurry, and can't take advantage of the free light source recharge
i use it mostly for long outdooring like camping / picnics, and you know that even 3x1500 mAh will not last you for a day/week
you can get a full charge in just 1 day (from sun rise to sun down) even on a cloudy rainy sky
But what about physically attaching a panel to the back so I don't have to carry extra stuff? Is it possible? How would I wire it up?

that works, but you wont be able to use the phone for like a whole day meanwhile waiting for it to charge, and be drained almost instantly
Have a look here>>>http://tinyurl.com/y2nrvsv
I have ordered one of these will do a small review when it arrives>>>http://tinyurl.com/2fun3k6
I have this traditional solution for emergency charging: http://www.portablepowersupplies.co.uk/
They have Solar Charger, too.
that solar one from portable uk is okay, i only like the "bag" idea of it, but it's shy in power & recharge rate when competing againts the 4200 mAh beast from DX

I have one, it has to be charge via usb, but I do that while I am on my laptop, and the bonus is that it will charge anything that connects via a mini/micro connection,

And leave the phone under the sun ?? A very bad idea, the heat will surely damage your phone.

Agreed
I don't think a little solar panel on the back of the phone will be capable of putting out that much power
I don't know about you but my phone spends most of its time inside my pocket so it is rarely out in the sun for the solar panel to work
Just carry a spare battery or get yourself the Samsung extended battery

Solar charger for SGS and other mobiles.
Few days ago I was searching for the Solar charger for my SGS in India.In local stores I brought 2 solar chargers but these are the china made chargers with very low quality internal battery.
Then one of my friend suggest me the Amzer 3500 mAh Battery Backup Solar Charger and Solio Emergency Mono Solar Hybrid Charger.
I ordered the Amzer 3500 mAh Battery Backup Solar Charger and believe me, the charger is one of the essential accessory for every mobile phone.
Also this Charger is available in India, USA and UK regions.
For India, take a look at this, http://www.fommy.co.in/Amzer-3500-mAh-Battery-Backup-Solar-Charger-P83981.htm
For USA and UK, visit http://www.fommy.com/
the one i mentioned back in post #8 is way better and cheaper
and free shipping with tracking number
trusted site
actually i hv read all the backup power all u guys suggest but i found that these all are just rebranding some chinese low quality products and it cant survive for long and there r some potential hazard that may end up damaging our sgs...i hv tried solar charger and some portable backup power before, the solar charger dun hv a high efficiency to exchange solar energy to electrical energy...it takes me too long time to charge it and it can only recharge the battery once. for the backup power, the mAh thing is not accurate, u need to try it yourself n c how many cycles u can charge the stock battery in order to estimate the true backup power battery capacity
I love my PORTAPOW
Received it yesterday.
5000 mAH USB rechargeable battery in a piano black case.
Fantastic.
This means I can go out on an all-day hike with GPS on.(Yep, I'm that sad)
The phone battery would last 2- 2 1/2 hours max with GPS (and MyTracks or similar on) while hiking.
Really good build quality.
Really good price.
(PS I am in no way connected with the company etc...)

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!
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:

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.
http://www.proporta.com/F02/PPF02P05.php?t_id=5330&t_mode=des
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!
Phil
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?
i am going on a travel abroad... will be using camera and camcorder a lot and wifi.... what do you recommend? a portable charger or extended battery? i want a cheap solution..preferably available from ebay
budget : not more than $30-34
extended battery
Battery will do better
I've just come back from holiday and had a portable charger. It was useful, but I often found that the battery would hardly last the day and there wouldnt be any place to charge it (you don't really want to be back in your hotel when you could be out sight seeing). Rather than trying to find a socket, I'd just get an extended battery. You can just swap it over and continue your fun rather than rooting around for power.
if i buy an extended battery i need to also buy a seperate battery charger so that i can charge the 2 batteries at the same time
it depnds how you'll spend your time.
but you can swap the battaries on the phone to charge them.
Normally charging the battary will last 1 hour.
again it depnds about the places you'll visit.
How many mAh are you planning on using per day? An extended battery will give you 3000mAh compared to the 1400mAh on the original battery. A decent portable charger will give you 5000mAh.
The only down side of using the portable charger is waiting for the battery to charge, most will do that at 500mAh so 3 hours to totally charge the normal desire battery from flat. However while the extended life battery has died the charger will still have about 1.5 charges left in it.
1 thing to point out unless you get a solar charger some portable charges will only charge from USB so make sure you have a way to charge that when out and about
I would get the potable charger (and remember to put it on charge when you have a spare min throughout the day) as when you replace your phone you cant really do much with the extended battery with your new phone, least the portable charger can be used over and over again.
i finally opted for a spare battery solution. I bought an oem battery for desire/nexus one. and i will buy a battery charger so that i can charge both batteries when i go to sleep so that they are both ready the next day
Get a portable charger instead. Taking the battery in and out can wear off the back lid easily.
Get a big battery, it's better than changing between batteries. As well you have to carry the portable charger when you travel. And you have to charge it, too.
So the extended battery should last one day (except you use GPS all time) and you can charge phone when you sleep.
I use a proporta turbocharger and I found it more usefull 'cause I can spare it with my friends with Desire HD, iPhone 4 and LG Optimus 7: with 2 of this we managed to stay all charged all day long and recharged both of them in hotel during the night.
For a trip is a Extended 3000mAh Li-Ion Battery a good solution. It comes with battery cover. Price about 25 $
For the daily use, its too big for me.

Extended battery for sure.
can aosp/sense kernel recognize bigger extended battery? afaik, there is a problem when charging bigger extended battery.
in my personal opinion, the standard battery (htc original) is much better than other and my desire remain slim. and if i travel, i prefer to use big portable charger to charge the handset when is not used. and charge them both when i sleep.
Most batteries with lots of ampere just have them as a tag... Check this site for information:
http://batteryboss.org/
I suggest you buy another original battery as from time any battery will lose capacity and this way you are flexible.
To charge you can buy a cable designed for charging the smartphone from your car e.g. HTC CC-C200 or the car dock from my signature.
Why you should use this: The data line is used for power and not for data and therefor the charger is recognized as a wall charger, not as usb cable. Thus recharge is lots faster (with 1000 mAh) than with any 3rd party charger/cable with 500 mAh although the charger itself could give you 1000 mAh (USB specifications!).
I'd go with an portable charger because you don't acutally need to restart your phone when plugin it in.

Thank you very much for the info.
I use a car charger (not HTC) which gives 1000 mAh and even with the original cable that came with desire, charging is slow. If I get this right, it is fault of the cable, right?

I suppose, best is you try it yourself - maybe a mate got one. As you may know USB allows only 500 mAh, using that secial cables that don't comply with USB (as they only charge) the producer can avoid this restriction.
Hi Guys,
1)
i am not able to understand why will people buy Anker / onsite or any other brands 2600 amp battery which is equivalent to samsungs battery ??
> Will it not give me the same life ?? If same life then should i not buy samsung ??
2) Can someone please suggest me a good powerbank - 6000 amp and above (those who have used and is worth)

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
