COBRA USB-C to Barrel Power Cable for Radar Detectors, 3.6ft — 5V/2.5A Reliable Power

Power your Cobra radar detector directly from any vehicle USB-C port using this 3.6ft USB-C to barrel connector cable for reliable 5V/2.5A power delivery.

Designed for modern cars that provide USB-C power instead of a traditional cigarette lighter or accessible fusebox, the Cobra USB-C to barrel connector power cable offers a simple, tidy way to feed power to compatible Cobra radar detectors. It eliminates the need for a hardwire kit by converting a USB-C power output into the barrel-style plug your radar unit requires. Lightweight and compact, the cable supports steady 5V/2.5A current for uninterrupted operation while keeping installation neat whether your detector is mirror-mounted or windshield-mounted.

How does this cable replace a hardwire kit?

This USB-C to barrel connector cable provides an alternative to tapping into your vehicle’s fusebox. Instead of running wires behind panels or installing a dedicated fuse tap, you plug the USB-C end into an existing 5V/2.5A vehicle power port and plug the barrel connector into your Cobra radar detector.

• Quick plug-and-play setup, no splicing or fuses
• 3.6ft length balances reach and cable management
• Cleaner routing options for mirror or windshield mounts
