Compatibility?Our radar power cord is applicable to the radar detector of the Uniden R1 R3 R7 DFR7 DFR8,Escort Passport Beltronics Radenso XP and the radar detector of the RJ11 telephone plug, and has a variety of lengths to choose from (Please pay attention to the interface type and length). Multiple Protection?The cable has voltage and current protection at the same time to ensure the maximum compatibility and excellent reliability of the input power supply of the radar detector.Note: This cable does not have data transmission function. Stable Output?Our cable adopts imported high-quality copper core, which strengthens the inner core material and greatly improves the stability of power transmission. The outer layer is made of high elastic PVC material, avoiding winding and durable. Patented Technology?Our radar detector cable has a built-in patented chip that supports all 5V and 12V on-board USB, and the interface output is compatible with the startup voltage of most radar detectors. When the cable is connected to various USB interfaces, the radar detector can be turned on stably. The Third Generation Radar Detector Cable?After the test of 3000+charging ports, we found that most of the on-board charging ports are incompatible with the starting voltage of the radar detector, and ordinary USB cables cannot start the radar detector, so we specially developed this special radar detector charging cable.
