I bought a car kit which included a cassette adapter and a generic charger. My cigarette charger broke so I never use it, it's still brand new in the package.
It comes with 6 different heads and the charger itself has 6 different settings to convert 12VDC to a regulated 3 / 4.5 / 6 / 7.5 / 9 / and 12 V DC current. The maximum current rating is 800mA
10$
