Frequently Asked Questions
Can I use these ovens while the car engine is off?
You generally should keep the engine running while using these devices. They draw a significant amount of amperage, which can quickly drain your car battery if the alternator is not providing power.
What kind of containers work best?
Use heat-safe glass or metal containers. Plastic can warp or melt if it touches the heating elements, and you certainly do not want a puddle of melted plastic in your lunch.
Do these devices actually microwave food?
Most portable options are actually convection-style heating boxes rather than true microwave technology. They rely on heating elements to transfer warmth to your food, which is why the process takes much longer.
Will these fit in a standard cup holder?
Almost none of them will fit in a cup holder. They are typically shaped like a small lunchbox or briefcase, so you will need to clear a flat space on the floorboard or a seat.
Are these safe to leave plugged in?
Never leave them plugged in unattended. These units can get very hot, and you should always disconnect the power as soon as your meal is finished to prevent any potential fire hazards.
