Although this is a 5V USB adapter it will not fit into a radar detector socket that uses the same plug. It won't quite fit in the box, but not only that, it doesn't deliver enough power to run a radar detector when plugged into a 12v cigarette lighter socket. I like the different adapters it has, but if it doesn't work in a car, I doubt it will work on any other device that uses a 5V plug.
