Questions
Can I leave a compressor fridge running overnight with the engine off?
Only with battery protection set appropriately, or with a separate auxiliary battery or power station. The starter battery alone is at risk.
Is a thermoelectric cooler a refrigerator?
No. It only cools a limited amount below the surrounding air, so in a hot car it may sit well above safe food temperatures.
