I found this little USB powered fan at Wal-Mart the other day for less than $2.00. It provides somewhat of a cool breeze... This particular fan works better but runs off 12 volts so I had to run it off my 6 to 12 volt converter. I replaced the motor with a 6 volt hobby motor but for some reason blows fuses as if it's pulling too many amps. I need to put the original 12 volt motor back in it and install one of these things in line and plug it into my Hella port. This same converter I used to solve my present issues with my Trabant and Citroen when cranking the engine over.
