Mine is plugged in and runs up through the engine compartment and comes out the hood and I can use ti from my seat or next to my rig.
I have a smittybuilt x20 and it is. It works about 20ft is all too. I don't like any of the wireless I've used. They all keep running longer than a direct wire set up. I feel like that could lead to a broken wire or rope and a bad day.
