The bottom line: this hardwire cord is best for owners who need to power up to three accessories at once without relying on a bulky cigarette lighter adapter. It converts a rearview-mirror or overhead sensor power point into four USB modules and three device connectors, keeping wiring discreet while supplying both 12V and 5V outputs when the engine is running.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal fit:\u003c\/strong\u003e The cord is designed to tap power from common rearview mirror or overhead module points so it can work with a wide range of vehicles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree-device installation:\u003c\/strong\u003e The harness has three connectors and four USB modules so users can run a dash cam, baby car camera and a portable Carplay screen at the same time.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMixed voltage outputs:\u003c\/strong\u003e Two 12V and two 5V USB modules provide the correct voltages for cameras and screens without extra converters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiple connector types:\u003c\/strong\u003e Six output wires including Type-C, Mic, Mini, DC3513, DC5525 and RJ11 cover many common power plugs used by car electronics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeat wiring:\u003c\/strong\u003e Hardwiring behind the mirror or overhead area reduces clutter in the passenger compartment and gives a cleaner installation than external adapters.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Dash cam hardwire kit is for drivers who want a professional-looking install for multiple car electronics without using a cigarette-lighter hub.
