Cigar Lighter Socket USB Adapter

Has anyone ever tried a common over-the-counter USB adapter in a 6v positive ground Packard with any success? Since USB is 5v, the only issue might be that there is no facility for making it polarity-less and if none are, one would be easy to make and I am thinking of doing so. Just wanted to be sure it didn’t exist already. The input voltage is not important and it could handle 6 to around 35 vdc without a problem so would work in 12v positive and negative ground cars too.
