Just want some opinions and ideas from people here since this place gets ALOT of people visiting and alot are clearly pretty intelegent.
Bascially i bought a car solar trickle charger that has an output of 4 watts and 18volts, my plan is to attach a female car socket to it plug a car charger into that, stick the solar panel in some light and plug the phones/mp4 players ect ect usb to the car charger and get some free daytime energy.
Possible? stupid? too good to be true?
This is the little adapter id plug the car charger into this adapter will be connected to the solar panel by alligator clips.
This is the charger it self made to trickle charge a car battery but im hoping that in some light itll have enough output to charge a phones battery and similer devices.
MOD EDIT: REMOVED EXTERNAL LINKS
No one has anything to say?
i'm already using a solar charger
just buy a solar battery backup from Deal Extreme
let it charge under any light source
then hook up your phone to it
done, presto, clean and simple
and you get to choose any size capacity that you want
i got a 4700 mAh

Iv already experienced that and they are crap, the solar cell is so small on ALL of them that charging takes days even tho its listed that itll be fully charged in a day which is utter crap since its an impossibility no matter how much sun because of the output of the solar cell and the battery they stick inside is a generic li-ion battery that wears out very quick.
one i had was a 1900mah battery and the other was 3200
mah or something and even when they were fully charged for days that couldnt fully charge any device..
This is why i want something that can fully charge a device directly from the sun rather than having to store the charge in order to charge anything, later on i can hook up a battery and a diode to store some of that power but for now i want something that isnt a lie and will just work.
edit: oh i thought you meant one of those mini solar chargers that trickle charge a battery all day sorry, yeah my plan is to store the charge from these two huge solar cells hopefully it will directly charge my devices without a battery tho.
Got some solar cells at home, was gonna try this, but need to find em first

Neat, i think to use thise you would just have to link some together attach then to a wire -to a diode- to a wire-toa battery and then hook that battery to what ever you want to charge.If youclink enough up you maybe able to charge a device direct from the sun.

the more advanced version of this is what i'm using http://www.dealextreme.com/p/4200ma...ry-pack-for-cell-phones-and-usb-gadgets-40210
i've charged my phone and several other devices using this
it's great for camping days, or when you know there's no power outlet in the next 100 KM

Charging directly from the sun seems to work for some devices but not others, anyone help me wire up a set of rechargable batterys to store that energy and a system to feed that power into my phones mp4 player ect?

Yes thank you so much for coming and ruining my thread how is anyone supposed to help when they cannot see what it is im talking about... i read the rules and dont see anything about it being agaisnt the rules to post external links... iv seen a million threads that have links just like that.
Even tho this thread has been up for ages thank you so much for only now coming and destroying it, you doing a great job well done.
Not sure if this is an issue, or if its standard. But here is what im facing.
A charge off the wall will get my Tmobile SGS2 to a full charge (from around 15%-20%) with the stock plug and cable in about an hour to an hour and a half. However charging from my laptop or from a car charger im only getting a total increase in battery 15% in an hour. I tried to use the stock cable with the laptop and got about 25% in an hour and a half. I tried to use the stock cable in my car and only got 7% in 45 minutes.
Anyone have any ideas?
When charging from the car or from a laptop, the power is limited to what the cable/charger can supply which might not be sufficient for the SGS2. For the car charger, you can try buying one that supplies more amps, but for the laptop, theres really nothing you can do, as it is limited by the USB cable itself.
Do you mean the USB cable or do you mean the actual plug & internal workings of the laptop? because i have tried several cables. And just also remembered that i tried the stock cable as well with crappy results.
you can buy a 2A charger, and it will charge a lot faster, that's what i use in my car
at home or office, i just use the regular charger, as i always carry extra battery packs
When you plug it into the laptop it only gives out a limited amount of amps unlike the regular charger that came with the phone. The one that came with the phone regulates the charge so that it doesn't overcharge your device or anything. The laptop USB plug is supposed to be meant for peripherals like a mouse and stuff so it doesnt give out that much amps, therefore charging slower than a regular charger.
I use the t-mobile rapid car charger, It can charge this beast in about 45 minutes. It also has a 2nd port for a 2nd device.
Deebo took your bike too?
Really?! I've never seen my charging current go over 700 mA, even with a 2 amp charger.
I'd happily give up some long-term lifetime for faster charging.

They have a home charger too that's a home charger plus car charger in 1. I use them in the cars but they're great for trips cause you have a 2 in 1 charger.
With 3 batteries and a external charger though, I never need a home charger and haven't even put this on a charger yet.
Just as most of the others have said here, the charge is going to be limited to what the source can put out. If you get another charger (2A charger) then it will be able to charger faster but you also want to be careful with using after market chargers there are some that can negatively affect your battery by overcharging which is when the phone gets fully charged but the charger does not ever stop with the flow of power to the device.
Ok Thanks all.
Guess i need a new car charger and something for the office.
Also did some crawling through "Mother of all battery life" thread found some good ideas there for making this thing last longer on the charge its got.
Im having the same problem my fone takes forever to charge...im pluged into the wall using the charger in the box n it took me no joke 7 hours to charge my fone!
Im on it rite now as its plugged i to the wall n im losing power instead of charging...i tested the voltage n its fine ...is tgere anythin i can do?

I, myself, actually haven't used the OEM charger that came with the phone. Although I did notice it is quite small and the phone battery is a 1850mAh (larger than normal) that might affect the charging rate. I am currently using the old HTC charger that came with my Sensation and it charges fully in about 2 hours. If you want a charger that charges your phone in an hour and a half, I recommend going into a T-mobile store and grabbing the Wallcharger they sell. It charges 33% faster than OEM chargers and does not harm your device nor kill your batteries.
You can find it by clicking here
Exactly same problem as OP.
OEM wall charger charges phone to full in couple of hours but laptop USB or car USB is doing at 10% / hour assuming you don't do anything on your phone but just leave it there to be charged. Otherwise you'll be losing battery rather than being charged.

As explained in previous post, this is due to limitations in the laptop USB drive and depending on what car charger you have, the phone might suck up more juice than it is able to provide.
so this is nothing a kernel or any other tweak can fix?

Yes, or if you have like an old microUSB charger from HTC or another Samsung phone (Samsung Vibrant) you can try using those.
the 2A chargers from BlackBerry are the best
So, you guys are seeing the phone draw over 700 mA (when the charger is capable)?
If I use my iPad charger (2A), I still top out at 700 mA, and the ~4 hours that go with it. :/
Even my 1A car charger tops out at 700 mA, that's why I thought it was a hardware issue.

I bought a 1000ma car charger off ebay, but it only seems to charge my phone very very slowly. I know it will be using a lot of power as the gps, screen etc is running, but i do the same at home with a charger that I know works and the battery % still goes up.
I also bought a 1000ma official HTC mains charger off ebay and it doesnt seem to charge my phone at all. (I've got a refund for this charger).
Is there an app that tells me how much current my phone is drawing from its external power source? Then I can test a charger as soon as I buy it off ebay, and if it doesnt do as advertised ill ask for my money back straight away!
Or is there a way to do it manually? I have a multimeter.
I also am very interested in this, as I have several car -> USB converters that do not state their output. It would be nice to know which one(s) are going to be the best for my usage.
I have a brother-in-law that is an EE, and I'll be seeing him this evening. I'll pick his brain and post back whatever I can find out...
You should be able to do it (somewhat) easily using your multimeter if you don't mind stripping a wire or two. You basically just connect the leads across some kind of load (you could try to leave it plugged into your phone, but may want to try something else) and then use the multimeter's probes to measure the current across the load.
The Nitro battery is model number BL-49kh. Not many cheap OEM options out there right now, but an "official" spare can be purchased from AT&T store:

Well Tokie, for your car, u can use something like this:
http://www.amazon.com/Energizer-Universal-Car-Charger-Pc-2ca/dp/B004YZI1T4
One of the ports will have a 1.5amp output and will suffice to charge your battery quickly.
And if you have a tablet or wanna go ultra crazy in charging your battery n burning it U can use something like this:
http://www.microcenter.com/single_product_results.phtml?product_id=0364269
That one has a 2.1amp output as well, enough power to burn a hole in your phone's battery LOL!!

I use 2.1 amp in the car and it charges pretty fast even while streaming spotify or radio through bluetooth with screen off. It helps to get through a day of heavy usage without swapping a baterry.

For those of you who are getting an external battery charger, will you let me know if it manages to charge the batteries to 100%? I currently use a universal battery charger, which worked great for my other phone batteries (would charge them quickly and fully, so when I popped them into my phone, it showed 100%), but for whatever reason, when I try to externally charge my Nitro's battery, no matter how long I leave it or put it back on the charger, it will only reach 88% or so. Then I have to fill up the rest by putting the battery in the phone and charging through USB. I know it's not my battery (I have two, and they both do it), so I'm just curious if other external battery chargers might be better. Let me know if it works for you! If it does I'll get whatever kind you have. I'd be super grateful, thanks!
I'm getting a legit LG battery charger specifically for the nitro. It'll take me about 2 weeks to get it (coming from LG itself in Korea) but when it gets here I'll try it n will let u know how it goes.

Btw Itiskonrad, where did you get your batteries from? Is it from that ebay seller or you got it from somewhere else? Just curious, cuz I've been searching everywhere, but nobody else sells it but that guy.

I ordered 1 extra battery AND the battery/batterycharger/cable from the ebay seller I mentioned earlier.
The batteries seem legit, they last just as long and have identical plastic casings. However, the two batteries I bought from ebay have a different sticker/label on them. They do not have the "FCC" markings on them or any other american legalese on them.
As far as the charger goes, it works great. I carry a battery in my wallet, one in the phone, and one in my backpack. I really like the peace of mind!
I also got mine from that Ebay seller. I'm confident it's legit. The build is identical, and it maintains charge and behaves exactly the same as the one that came with my phone. It's just probably the battery for the Asian Optimus lte, hence no fcc and different labeling. I'm not worried, and I'm pretty careful about batteries.
@red solo cup, do you know if the charger manages to bring the battery to 100%, ie, when you pop it in the phone and turn it on, do the battery stats actually say 100? My current charger brings it to around 90%, which is not bad, but if I'm going to buy another charger, I'd like it to max out the battery completely =) Thanks!
I have not checked Battery Monitor Widget immediately after putting in the battery, so I cannot absolutely confirm that the battery charges to 100%. However, I have noticed that the battery in the notification area was completely full, including the little "nub" on the left of it.
I will check this out when I get back from work tonight.
If the nub's full, it's at least at 95% I'm pretty sure.
Damn, I don't mind getting it from him, but he posted that it will take almost 20 days to a month for the item to get to me! That's frigging much too long for shipping something overseas. Things I get in China or HK doesn't even go beyond 2 weeks the longest.

I checked and the LG charger does indeed charge the battery up to 100%
@aquariuz: I really cannot recall how long shipping took as I ordered the battery on the 15, and the battery+charger on the 21st. I was away for the holidays, but by the time I got back to my place on the 28th they were both in my mailbox.
You're the best! Thanks a bunch! Ordering mine ASAP! =)
24v input
Has anyone found any dual USB (2.1a and 1a) with 12 - 24v input? I run crane and sadly in most of our cranes the Cig Lighter socket is running 24v.
I have a few 12 - 24v input single USB chargers with 1amp out but.. I'd love to find a dual. I have to run my speakers and charge my phone or mp3/RADIO -- seeing as how Optimus doesn't have a FM tuner

I found this on amazon. The specifications specifically state: "Input: 12-24V DC; Output: 5.0V DC 2.1Amp" Plus it is only 5.99+free shipping.
I have this and the specs on kensington's website state "Input: 10V-18VDC, Output (30pin/USB): 5VDC-3100mA.", So I assume that will not work.
so if i have to buy a car charger, what is the MAX specs i can use for the LG OPTIMUS LTE?
I recently sold my old Toyota Rav4 which only had a standard cigarette lighter car charger. I used a cheap charger I've had since my old Blackberry Tour to charge my ET4G. I work on the road a lot and used the car charger a lot for about the last 10 months til my phone started dying on me. Sprint store tested the phone and said the battery was slightly swollen and definitely showed signs of being damaged which in turn damaged the terminals on the phone causing constant reboots. I paid $35 to have Sprint/Samsung replace the phone as it was less than a yr old and under warranty.
I now have a new car and new ET4G. New car has USB port under the radio as well as 2 standard car charging ports. I've done several searches and read several threads about different voltages and which ones actually charge phones and tablets etc but none have answered my question. The question is is USB charging any safer than standard car charger? I've been told by a friend that fluctuations in the cars battery can send different amounts of charge to the phone and damage it over time. Both methods charge my phone so I don't care which one I use though I'd rather use USB as my USB cord is just 1.5 feet long (perfect length to reach my phone mount).
For some reason they actually gave me a new ET4G not a refurb and it works great. I don't want to damage the battery on this one and would like to keep it alive and sell it when I upgrade phones around December. That's only a few months away but I'd like to know I'm not damaging the battery in the mean time. Any input would be great. Thanks in advance and sorry for the lengthy write up.
Anyone with any input? Anyone use USB to micro USB in their cars?
Don't know if the new car is also a Toyota but here goes...
04 and 10 Toyotas - tried a cheapo MicroUSB charger and the voltage actually drained the battery! So I bought a $10 lighter to USB port charger, plugged in the cable and charges like a champ!
It really depends on how much power they're pushing through the USB port and whether the E4GT can regulate it. I'm finding it to work great - and MTP mode should give you access to the music on the head unit. (Again, *if* it's a newer Toyota...)
Most radios and internal usb ports will be 500ma (same as a standard computer usb port). That is only enough to charge the phone when it is sleeping. Just snag a $10 adapter that puts out 1a.

Thank you both. I just drove 2 hours with Bluetooth on and GPS running while connected to USB. Battery drained 8% which isn't much so it wasn't strong enough to charge it but slowed down drain.
The new car is a 2013 Hyundai Elantra GT (It's a new model to Hyundai). The cigarette charger doesn't seem to over heat the phone like my Toyota did. I'll ask Hyundai how much charge the cigarette lighter port puts out I guess.

I highly recommend the OEM Motorola car charger. Got mine on Amazon for $6. It was the only charger that would work on my old phone because it had voltage control. Any generic charger would only drain my battery while still displaying the charging animation.
Plus it has a cool blue glow to it.

Sweet, I'll take a look at it. I heard back from Hyundai and the guy said he has no documentation on it yet since its a new model but if I wanted to swing by he could test it real quick and let me know. Today was hot as hell. I got in the car and blasted the AC. Put the phone on the USB charger and after about 10 minutes I got a warning on my screen saying phone is too hot and charging has stopped. I didn't even have GPS on or anything. I quickly unplugged the phone and it was fine after that. How can the USB overheat the phone when it can't even charge it while I run GPS and Bluetooth? I wasn't too happy. I used a brand new USB to micro USB cord from Monoprice (5 pin if that makes a difference).
