The standard car charger doesn't have a high enough output, try to find a aftermarket one that has a 1 or 2 amp output and not the .5 or less that most are. I believe most are a 450 milliamp (.45amp) so it charges slowly, like a trickle charger, the higher the output amperage the quicker it will charger, same with your home charger they standard one that comes with the Lucid takes forever to charge, so I use the one that came with my LG Ally - it's a slightly higher output and charges faster. They say to try to find one that charges tablets - they are around 2 amps output and will charge it pretty fast....
