In today’s fast-paced world, radar detectors have become a necessity for many drivers who want to avoid speeding tickets. These devices help alert them to police radar signals, ensuring they can adjust their speed accordingly. Radar detectors usually come with power cables that plug into the car’s cigarette lighter port, providing the necessary power to operate the device. However, as technology advances, USB power cables are becoming more popular as an alternative option. In this article, I will explore how you can power any radar detector via USB, providing you with greater flexibility and convenience.

Using USB Power Cables:

  1. USB A to RJ11 Cables: One option to power your radar detector via USB is by using a USB A to RJ11 cable. This cable connects the USB port of your device to the RJ11 port of the radar detector, allowing power to flow through. It is a simple and convenient method, especially if your car already has a USB port.

  2. USB A to Cigarette Lighter Adapters: Another option is to use a USB A to cigarette lighter adapter. This adapter converts the USB power output into a cigarette lighter socket, enabling you to plug in your radar detector’s power cable. This is a versatile solution as it allows you to power other devices that require a cigarette lighter port as well.

  3. USB A to Barrel Connector Cables: Some radar detectors come with power cables that have a barrel connector instead of an RJ11 port. In such cases, you can use a USB A to barrel connector cable to power your radar detector via USB. These cables are widely available and provide a convenient method of powering your device.

  4. USB/Cigarette Lighter Car Bricks: If your car only has USB ports and no cigarette lighter socket, you can opt for a USB/cigarette lighter car brick. This device plugs into your car’s USB port and provides a cigarette lighter socket. You can then connect your radar detector’s power cable to this socket and power your device seamlessly.

Special Consideration: Rodenso DS1:

If your car only has a USB Type-C port, powering a radar detector can be a bit tricky. However, the Rodenso DS1 is a great option for such situations. This detector comes with a USB Type-C port and can be powered directly from it. It eliminates the need for adapters or special cables, making it a convenient choice for USB Type-C users.

Importance of Power Output:

It is important to consider the power output of the USB ports in your specific car. Different USB ports provide varying levels of power, and some radar detectors may not receive enough power from the car’s USB port, causing issues. It is advisable to consult your radar detector’s manual or manufacturer’s website to ensure compatibility with your car’s USB ports. Using USB power cables can also be useful for powering detectors at home during setup or programming, providing additional flexibility and convenience.


Powering any radar detector via USB offers flexibility and convenience to drivers. Whether it’s using USB A to RJ11 cables, USB A to cigarette lighter adapters, USB A to barrel connector cables, or USB/cigarette lighter car bricks, there are numerous options available. Additionally, the Rodenso DS1 is a great choice for cars with only USB Type-C ports. However, it is important to consider the power output of your car’s USB ports and ensure compatibility with your radar detector. By utilizing USB power cables, drivers can effectively power their radar detectors, enhancing their driving experience and ensuring their safety on the road.
