Cordless radar detectors, also known as wireless radar detectors, operate on batteries instead of requiring that you plug a power cord into your cigarette lighter. Wireless radar detectors are popular because of their added convenience. If you believe you will frequently move your detector between multiple cars, the idea of a battery powered wireless radar detector may be appealing. Motorcycle drivers may have the biggest need for a cordless radar detector. On a bike, cords can really get in the way, and some motorcycles do not even have a cigarette lighter plug.
Even with all of the benefits of cordless radar detectors, we do not recommend that you buy one unless you specifically need the cordless ability. Because cordless detectors have to be very careful about their power consumption, they generally don't perform as well as similarly priced corded models.
