Hey everyone, trying to decide on what to use for a car charger for my Rezound. I've read conflicting information regarding how the car chargers work. Some do a "Trickle charge" which basically just keeps whatever your phone is currently at from going any lower, and some that work like an AC charger giving a full rapid charge to the phone. Bottom Line: When in the car I'd like to run all the goodies: GPS, Internet Radio, Full Push Data to the phone etc, and have the charger not only keep up but manage to charge the phone so it's more than when I started the trip! This is of course assuming it's not being held back by a GPS dock or whatever. I see there are dedicated chargers, and chargers that have USB ports where you just plug the USB cable into it to the phone. Is one any better than the other? I'm assuming the latter would be more convenient/versatile. I'm also making the assumption the higher amperage the better. As long as heat isn't an issue, then the phone will only take the Amperage it's capable of drawing. Is there a voltage spec that must be adhered to? Or can it handle 12V? If it's USB, will that already be taken care of voltage wise? Any help would be greatly appreciated as I'd like to buy this once and know what's possible and reasonable to expect how close I can get to those goals. Thanks!
