Idling your engine all night to stay warm burns fuel, wears your engine, and in many states will get you a knock on the window. There's a better way.
The Fredlox Direct 12V 2KW Diesel Air Heater runs on your vehicle's diesel fuel supply and pushes steady, controlled heat into your cab without touching the engine. The Bluetooth app and LCD display let you set your target temperature, monitor output, and schedule run times from your phone or right on the unit — no fumbling with knobs in the dark. Built for trucks, cars, buses, and RVs, this is the in-cab heating solution that professional drivers rely on for cold overnights without the fuel waste of idling.
