never go cheap on a car charger... it'll waste your money and time. learned the hard way with 2 blackberry chargers i got from ebay.

i bought the first one for 5 bucks, broke in 5 days, bought the second one from a different seller for 10 bucks, broke in 2 weeks..

i had no idea how they had 100% feedback...

BUT, if you really want it, go for it!

(go Incase or Belkin duel USB)
