If you need to safely convert power from AC outlet to DC power, use this handy 12 Volt Adapter.
Early model Passport 9500ix detectors with serial numbers starting with "19" require a 12v power source as well as the USB cord to be able to update from Detector Tools. You can power these detectors in your vehicle and then connect to a laptop, or you can use a 12v power adapter in your home or office and connect to a desktop computer.
This 12V cord was just what I needed to connect my 9500ix to my home PC so that I could update the software on the unit. Even though the unit came with all the latest speed and red light cameras at the time I do try and update once a month since my area is adding these cameras on a daily basis to intersections and freeways.
Since I do not have a laptop I can take out to my car to do the update I need to bring in the radar detector to my home PC to update the camera locations and backup my personal data. This power cord allows me to power up the unit while I am doing this in my home so that I can know the locations of all the working cameras in the area I travel in on a regular basis.
