7 Best Microwaves For Cars Of 2024! (Tested & Ranked!)

Today’s modern microwaves range from simplistic designs with dials to fully loaded voice-activated interfaces. I found that The RoadPro RPSC-197 offers the perfect mixture of convenience and modern practicality for road trips or tailgating.

How I Picked
Power Requirements

Cars don’t offer standard AC voltage connections without an inverter. Therefore, I knew I was either going to need an inverter or a model that runs off DC voltage.

Power Output

Microwaves are rated in watts and certain foods will require a specific wattage output to properly heat. I chose a model that would deliver all the watts I needed for my desired dishes.

Overall Footprint

You are obviously going to be much more space-restricted cooking in a vehicle. I made sure my decisions were compact and portable while also being powerful and spacious enough to deliver the watts I needed.


You’ll always pay for price and convenience, but that doesn’t mean spending the most is always the best option. I didn’t want to pay a ton just to get the heating convenience and power I needed. I don’t mind spending a little more to get more if the investment is worthwhile.

Designed to look exactly like a modern lunch box, the RoadProRPSC-197 offers affordability, practicality, convenience, and aesthetics wrapped up in one neat little package.

Quickly and efficiently heat foods to 300 degrees F with the 12-volt power connection.

The lunch box already comes fitted with a cigarette lighter adapter that will plug right into your vehicle.

No need for complicated wiring messes or purchasing an additional inverter. This bad boy is set right up for DC voltage out of the box.

Its unique design is made just like a lunch box with spatial dimensions of 11” x 8.35” x 8.15”.

It even features the patented clasp on the front along with the top ergonomic carry handle.

Complete convenience and portability all in one package. The 5 ½-foot power cord only adds to the overall convenience.

With the 300 degrees F of cooking power combined with a heating surface that will hold 8” x 3.75” x 2.5”, you won’t have a problem heating typical dishes.

Unfortunately, the machine only comes available in black, but the design and aesthetics are already pleasing.

The box also features a handy storage space that’ll comfortably hold the entirety of the 5.5-foot power cord.

With a weight of only three pounds, you’ll never have to worry about exerting yourself, while still reaping the benefits of a rough and rugged exterior design.

There are additional disposable aluminum pans available for this exact model, but they must be bought separately.

What Has to Be Considered When Picking a Microwave for a Car?

Consuming the same old meals over and over can get tiresome.

Eating out of restaurants and convenience stores isn’t a viable alternative with today’s ever-increasing prices.

If you are looking for a more unique, healthier, and all-around smarter way to enjoy lunch, look no further than the portable vehicle microwave.

When you invest in the right device, the possibilities can become nearly limitless. 

The only problem is choosing the right device. You first need to begin by defining your needs or desires. What types of foods do you desire? 

Are you looking to reheat leftovers, warm up canned goods, or create made-from-scratch decadent dishes? 

You can see from some of my picks above there are models that’ll do a little bit of everything. You can never go wrong in those respects.

It is also helpful early on to establish your operating parameters. Meaning, do you have a DC to AC inverter handy? Do you plan on buying one?

Maybe you just want the system to plug into your cigarette lighter. Do you have access to 24 volts DC? 

Answering a few simple questions like this and others will help cut down on the multitude of options available.

Combine the answers with your most preferred features and you’ll have found exactly what you are looking for.
