So I am a car buff and I hate having wires hanging everywhere when I drive. I had a car dock on my evo 4g and so I had to buy one for the 3d. I bought the one that sprint had at the store and I really like it. My car has a fused accessory wire that goes to the area around the rear view mirror which makes it real easy to wire a charger in up there so you have a short wire that comes down from around the mirror instead of a big one hanging across the radio and taking up your lighter plug. The question is what will suffice for a charger. Looking at the one that I bought from sprint it says its a mini usb with a 5v and 2a out. Is there anything special about this or will any decent voltage protected 5v 2a charger do the job. I really want to find one that is set up for a hard wire so I don't have to cut into it. If anyone has one they can recommend me that would be awesome. I am not going to cut into the one i bought from sprint cause its to nice and i paid to much lol. The guy at the store gave me this speech about cheap chargers overcharging and yada yada i think that is a crock of chit but I dunno. My guess is cheap chargers don't protect against voltage surge and have low amperage.
