I'm not even going to more to the street vendor, have fun in Chinese shops. Here in Brazil this vehicular charger costs a 10 to 15 real. In china, with shipping and all, it comes out 2 dollars and little.
It worked, but I don't know for how long. This Chinese boots usually heat up and burn!
Has a good amount of cable to let the phone anywhere in the car.
Purchased on BuyinCoins, that always has some very cheap! I leave the link to the product:
