The built-in chip converts the 5V USB input up to the 12V DC output required to run most radar detectors. Just ensure your detector uses an RJ11 or DC55×21 (5.5mm × 2.1mm) connector.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I know if my radar detector is compatible with this cable?\u003c\/h4\u003e\n\u003cp\u003eA: Check the power port on your radar detector. If it uses an RJ11 (telephone-style) or a DC barrel connector measuring 5.5mm outer diameter × 2.1mm inner pin (DC55×21), this cable is compatible. We recommend verifying your detector's connector type and voltage requirements before purchasing.\u003c\/p\u003e\n\u003ch4\u003eQ: Is the 1.5M cable length enough to reach from a USB port to a windshield mount?\u003c\/h4\u003e\n\u003cp\u003eA: In most vehicles, the 1.5-metre (approximately 5 feet) cable is more than sufficient to route from a dashboard or centre-console USB port up to a windshield-mounted radar detector, with enough slack for a neat, tidy installation.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this cable safe to leave plugged in while driving?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The chip encryption technology manages voltage conversion and monitors current consumption to maintain stable output. The cable is also rated for operating temperatures between –20°C and 80°C, making it safe for year-round in-car use.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Will this USB to RJ11 radar detector power cable work with my car's USB port?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes — the cable is designed to plug into any standard car USB port (5V output).
