Review on BougeRV 42 Quart Insulated Protective Cover, 12 Volt Portable Refrigerator Cover, Car Freezer Cover (Refrigerator NOT Included) by Jim Escobedo

It does actually reduce electricity usage by some amount, like at 32F setting 11 Watt without, vs 9 Watt with this cover (measured with killawatt over 15 hours). Seems like a small difference, but may be a big deal if a fridge runs from a battery. It has all proper openings for control panel, cable attachment, vents, handles (comes with its own straps which are pretty convenient). Opens really easy. Has a bunch of convenient pockets on the outside for cables and other stuff. Protects the case. Seems like only advantages so far. Nice value for money.
