Cordless radar detectors operate on batteries instead of requiring that you plug a power cord into your cigarette lighter or 12 volt port. Cordless detectors are popular because of their added convenience, specifically for motorcycle owners or those who frequently change vehicles.

Most cordless models provide the option of using batteries or a power cord. This is a very nice feature and can save you if your batteries die unexpectedly. Popular cordless detectors are the Escort Solo S2, the PNI Steele Eye, and the Whistler 1788. Because of its combination of performance and features, the Solo S2 could definitely be considered the best of the cordless models. The Steel Eye and the Whistler 1788 have rechargeable batteries and are good options if you're looking to spend a little less.

Even with all of the benefits of the cordless 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.
