I am considering purchasing the subject AC/DC combination charger for use on my BB Curve 8320. It appears to be a very handy 1-piece charging device utilizing both a typical AC outlet OR automobile 12VDC charging outlet. Unit has fold out double AC outlet prongs and typical 12VDC connector ("cigarette lighter" type) all in 1 housing. Has anyone purchased/used this device? Please share your recommendations/feedback OR any info that may help before I purchase this device from the Internet. Thanks!
