Hi guys,
was thinking about buying a solar charger with batteries inside but I have no experience at all with solar cells, is someone using those kind of devices? I'd like to know your experiences and, if possible, some brands.
thx
Try Akita Solar Charger, I use it with satisfaction.
I tried freeloader but it seems to charge the diamond for about 20 mins then its dead. Appears to add approx 1 bar to battery indicator. not good!
I bought powermonkey explorer and i just love it.
It requires pretty bright light to charge phone straight, but if you charge the battery thing and phone with it then it is very good.
I charged it fully from USB and it charged tomtom device from 0% to 100%, my ipod nano to full and diamond from 30% to full and had like 20% of juice left
I just love this powermonkey, going to get solargorilla as soon as it comes to market!
Would one like this do the job ?

Yes a Powermonkey with solar slave, or a Solio.
But all these solar charger need direct sunlight. If cloudy, they can take 1-2 days (daylight days not 24hr days!) to charge
You are probably much better off with a external power pack that uses 1 or 2 standard AA batteries
Finally I bought a Solio solar cell w/ Li-Ion battery inside. Solar charge is the "last hope" because it takes a long time to charge itself or charge the Diamond but can be charged using a normal socket and then charge the Diamond a couple of time. Of course the solar power it's a good solution if you plan a camping in Corse on August
thanks all
I'm going camping soon, and I need to be reachable 24/7, so I thought maybe a solar charger would work. Has anyone had any experience with these? How is the charge rate?
Any other cheap solutions? A charger that uses batteries would cost too much in batteries.
I tried a cheap eBay solar charger on my previous phone (HTC touch cruise). It was a charger with internal battery. So you could charge it during the day in sunlight and use it to charge your phone at night. At least... in theory. A full solar charge (about 1 week in the sun) gave my phone 10% extra juice I haven't tested it with my desire, but I expect it's even worse since the battery capacity is larger.
I'm not an expert, but I think the "mAh" capacity of the solar charger should be a lot higher (like double or more) than the device you're going to charge. For instance, if you connect it to a notebook (with battery capacities from 4000 mAh and up), the power will be succesfully transferred. But even then, I don't think you can fully charge your phone without draining the notebook battery completely. The Desire battery has 1400 mAh.
I would advise to look for better quality (and more expensive) alternatives. Like the solar chargers they use on campers to power a TV or fridge. Especially if you want to be reachable 24/7. If you want an emergency charger to give you enough power to make one phone call a day, a cheap solar charger will be sufficient though.
I'm a new user so I can't post link. But try googling "High Capacity Solar Charger and Battery w/ Flashlight (11200mAh)" and click on the 1st result. Bought that and am very happy with it. the charge rate is almost the same, if not the same, as the wall charger. it's got flashlight and mosquito repellent too.
theoretically it can charge the desire from zero to full 8 times before you need to charge it again. but you know it will be lower than that.
if you're looking for a cheaper solution then try googling "Solar Charger USB Hub" and click on the 4th result. but the charge rate will be substantially lower though. hope that helps.
I usually use the SOLIO solar cgarge, maybe a little expensive than the ebay but work very well, i use it about from 3 years and never had a problem.
I've testet him in very extrem condition.
You can see it on the solio web site, i have the classic version.
one of the best used by forces in iraq etc is the "solar monkey" make sure if tyou get one you choose the correct type for your device as different devices are more power hungry than others, i'd go for the top link the power traveller

Have a car charger and will be near your car when camping? Then just use that. Worked fine for me during a 5 day camping trip.

No. We're going backpacking. Tents and sleeping bags on our backs and sleeping in the outdoors. <3
Thanks for the links guys. I will check them out. I could attach the charger to my backpack with the cable going into phone which is in my pocket, so I can charge it while we're hiking. I'll look extremely geeky, but it'll work I hope.
I need to be reachable for work. I'm also bringing my laptop with me in case there is an emergency at work. Hurray for tethering!
It doesn't really do "camping in the wilderness" any justice though.
If you are in the UK i wouldn't waste your money on a solar charger...i'd spend the money on some nice waterproofs lol.
Got this here: Energy Trends ET 3000
Wondering why they don't have a language selection... http://www.energy-trends.eu But you can see it here:

Also described here: http://forum.xda-developers.com/showpost.php?p=7093929&postcount=13
But I assume that they don't deliver to the UK.
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
mini/micro portable power pack

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...)

Hi,
not sure if anyone else uses this site! but it is nothing short of AMAZING!
they sell everything! CHEAP! with free delivery around the world also...
I love dealextreme :d
bought this one this summer for my Desire Z ... works perfectly but the charging time is not so great...
Genuine Micro-USB HTC charger delivers ~750mA
this one frome DX delivers only 250-300mA when the Desire Z is docked
you think a g2 with a mugen 3600mah would fit inside? looks close...
nope ... because the bigger battery cover it won't fit on the cradle

Also the angle is very close to 90 degrees so kinda hard to view if your tall.

My DZ charger says 1A on it.
1A is the max output the charger can deliver it's not the power he will deliver all the time...
if you install the widget app "BatteryMonitor" from the market you will see how much power your phone use when it's on charge.
Is it true that different chargers will affect battery life? I mean once we charge it to 100%, shouldn't the battery discharge at the same rate under the same usage even though we use a different charger to charge it up?

the only thing I have noticed that affects battery life is that deep discharging the battery (below 20%) causes early battery death - I have learned this the hard way!
Aww dang, I have the habit of running my battery till the red before charging it. Guess I gotta change my habit. LOL!
Okay I know when most of you look at this charger and see the price of it going for you'll be like it's cheap and will not work the way you want it to... Well that's a lye your telling yourself.
Why get this? Because I bought it for a quick and easy use when I'm out and about. And every time my phone's on low charge I always use this charger because it almost charges your phone completely in like an hour and it does not over heat your phone either. I recommend this to everyone

MYBAT Travel Charger (with IC chips) does the IC stands for insertcoin chips?
Can you explain it a little better? It's rated for 500ma while the stock charger is 1a. How can it charge faster while having half the rated output and producing less heat at the same time? Also, the connector looks like a Mini-USB connector instead of Micro-USB.
