Yes, you can run a BougeRV portable fridge in your car. It can be powered directly from the car’s 12V accessory port or connected to the battery.
While driving, the alternator keeps your battery charged, allowing continuous operation. When parked, the fridge will draw power from the car battery, so the runtime is limited. To maximise efficiency, keep it in fridge mode, minimise opening the lid.
And we recommend running a large portable fridge via a power station or solar generator to prevent draining the battery.
