✓?Multiple Choice?We have charging cables of various lengths, 6.56ft :B0BLTRZMVM. 9.84ft: B0BLTQ4R5T. ✓?Wide Application?Radar Detector Power Cable is also suitable for Replacement Power Cable supply for Cobra RAD 350 380 450 480i XRS9370 XRS955 XRS5300 XRS7700,Uniden DFR1 DFR3 DFR5 whistler etc with DC "3.5" jack Radar Detector. ✓?High Quality Copper Material?Industrial grade high quality copper conductor is used, which is closely connected with the conductor to improve the transmission quality and avoid external interference. High elastic PVC adhesive layer, avoid winding, not easy to damage. ✓?Stable Working Performance?The radar detector cable adopts a new chip encryption technology to ensure that the radar detector can be stably turned on when the cable is connected to 5V or 12V USB interfaces,giving you all around protection wherever your adventures take you. ✓?The Latest Patented Technology?After experimental comparison, the ordinary USB cable is incompatible with the working voltage of most radar detectors, which causes the radar detectors cannot be started.To solve this problem,our department has developed a radar detector cable with two working voltages at the same time. You can switch the USB socket at will without affecting the use of the radar detector.
