Conceptually solar chargers are a cool idea, but they are slooooow. To get anywhere near a decent charging rate you'd need a huge panel, not something you could carry around. The solar charger/battery combinations you see that can fit in your pocket will take the better part of a full day in direct sunlight to charge the battery, that's why they always come with a charging port for a plug-in charge.
Now if you plan to get marooned on a desert island I'd say by all means get one of those, it'll be the only way to keep your phone alive with no available power sources. Of course there won't be any cell towers anywhere nearby so all you'll be doing on it is playing games.

How USB charging works, or how to avoid blowing up your smartphone | ExtremeTech
There is a huge variance, then, between normal USB 2.0 ports rated at 500mA and dedicated charging ports which range all the way up to 2100mA. This leads to a rather important question: If you take a smartphone which came with a 900mA wall charger, and plug it into a 2100mA iPad charger, will it blow up?
In short, no: You can plug any USB device into any USB cable and into any USB port, and nothing will blow up

Well, That solves That IF it even Needed solving.
I'll not be taking a chance, especially with no insurance, on Any car charger. (And one from Metro would be my only choice IF they only charged One kidney for it. )
I'll just take my home charger if I think I'll need a bump up. I've had No Problem At All making it past the 12 hours I'd likely have the phone away from somewhere the standard charger couldn't be used.
Plus, since the Motion and Spirit charger are the same, I'm still using my Motion charger while my Spirit charger is on deck, unopened if the Motion one goes TU.

Metro pcs not selling something for a kidney over its normal price ha. you are looking at a company that sell 2gb micro sd cards for like 20 bucks and can't even tell you the class of it.

I made a 5v USB charger for the car using a pair of 7805 regulators and a few caps. Also added a small laptop fan to cool the linear regs, and it's working great. A few bucks in parts and prototype/test time.
The pair provides 2A max, but the Motion still states "Slow Charging". Regardless, my supply puts out enough current to charge the Motion and my N7 while they are actively in use. It's grafted into the glove box of my VW.
Makes me wonder how the motion calculates if it's "slow charging"... That's a topic for another thread...

Ok, a short means no voltage, the leads touched somewhere, and fried the charger or blew its fuse. Over-voltage, over 5 volts DC, can cause damage from over heating your phone. Lower voltage (<5vdc) would probably do nothing, no charge at all, or a slow charge rate. There is a simple battery charger built in the phone, but it has its limits.
The USB Data leads can take 5 vdc indefinitely with no harm by design.

Ever heard of not giving speakers enough power??
You can never give too much power to speakers, but giving not enough can blow them out.
I do sound, so I know about that stuff, yes I know a phone works differently, but it could be that the wires are shorting the phone out because they are touching, not shorting the car charger.

Okay.....stupid question time. My Metro LG Motion came with a charger that has the LG logo (circle with LG) on it. Do all these posts mean my charger is not an LG?
The charger that came in the box with your phone is genuine LG.

Car charger that MetroPCS sales is a third party charger that has killed a few phones that we know of. Don't know how many people don't post here on AndroidForums.com

Sammyz, this happened to me too, kinda... My girlfriend has a Sony Xperia Ion, and whenever I plug my phone into her charger mistakenly, I get the BSOD, then the phone will not power on or unlock or whatever. Every time it has happened, yanking the battery and putting it back in fixes it. One time it still wouldn't turn on, so I removed the SIM, replaced it, and viola, it worked again.
Not sure if you have the same issue or if the phone is totally toasted, but I can tell you I am more confident that it is NOT simply a car charger issue, because this has NEVER happened to me on a car charger. I would say the issue is with non-LG cords/chargers. Bottom line: try to stick with LG proprietary material. I haven't ever seen this happen on an LG cord/charger.

I told everyone man, it was totally done. I tried EVERYTHING.
NOTHING would bring it back and it is a car charger that killed it.

You can't buy what doesn't exist. 
LG has basically NO factory charges available on their website.

Well using only the USB cord that comes with the phone is the best place to start

More news on this front, but a little different.
I had a friend over with his own charger cable and wall brick. I ask him to charge my phone, so he plugs it in to his brick, my cord. Screen goes black, phone reboots and shows the boot screen, then dies again. It hasn't turned on since. No amount of charging or anything has helped. So, be careful what you're plugging into cos apparently these Motions are fragile.

Have you tried yanking the battery, removing the sim card, waiting about ten seconds, replacing sim then battery and trying to boot it up? Or try booting out without the sim inserted. I had a friend completely fry his sim, but the phone would boot just fine without it.

I've tried that, leaving it on the charger for a while then trying to power up, powering with the cable in USB with and without battery and SIM, and every other thing I could think of. I really didn't want to accept its untimely demise.
He's dead, Jim.
