How We Benchmarked All These Best Portable Microwaves?

In our research, we included various portable microwaves, food warmers, and stoves out there in the market.

Essentially, all these models had almost identical hardware with an exception of the few that were top-notch models but were also high-priced.

The benchmark included factors like ease of use, cooking quality, heating efficiency functions, wattage, and size.

Then we delved into hundreds of customer reviews on different forums and retail sites to know exactly what others think of these shortlisted microwaves.

Here is a list of the most important factors involved in going through our picks for the best portable car microwave.

Small Footprint

Nobody would want to carry a bulky oven cavity that is hard to manage and provides no reason to be called a mini car microwave.

Therefore, we made sure we only choose the microwaves that offer the smallest size without compromising on the heating efficiency and overall cooking experience.

Ease of Use

We wanted to choose microwaves that offer easy-to-use interfaces. Hence, we skipped all those models that had complex functionality and connectivity.

In this process, we only shortlisted the smallest microwaves that were both easier to use and manage.

Even Cooking

We cannot say that if any one of them exceeds all others; but we only shortlisted the car microwaves that offered the most variety.

We analyzed different portable microwaves available in the market and wanted to select the ones that offer to cook a variety of foods, from frozen meals to baked potatoes, quickly and evenly.

Reliability and Owner Satisfaction

It would not be fair if these results were solely based on our own evaluation of different factors.

We felt it was important to take into consideration the feedback of customers.

We accumulated a lot of customer reviews available on the different retail sites and forums for these different 12-volt car microwaves purchased between 2018 to 2019.

After an extensive evaluation, we think Road Pro 12V Portable Microwave wins the race here between all the microwaves that we’ve reviewed so far. It is easier to operate, perfect for warming up foods, and even cook raw meat at 300°F.

The Winner

The RoadPro 12 Volt Microwave is very affordable, simple to use, and provides great ease for drivers who travel a lot and it can be simply connected using a lighter-type outlet in any vehicle.

RoadPro even offers a cookbook along with the portable microwave that offers quick-cook recipes to cook right at your front dash.

Additionally, the best part of this mini microwave — RoadPro portable stove, is that it can cook foods up to 300°F, enough to even cook raw meat.

But one thing to note here is that since it uses minimal 12 volts, it can take up to 15-20 minutes to heat up to this level.

At all costs, we now have the option to have our favorite baked potatoes or frozen mac in-and-out warm right at our front seat with this mini stove.

In terms of its portability, this compact 0.34 cubic feet smallest microwave only weighs at just 3.2 pounds.

Complimentary to that is its considerably less bulky size. It is smaller than all the conventional over-the-counter microwaves and can easily be adjusted at your front dash or armrest.

To boot, it even warms up when you’re on the go – an exceptional feature that lets you perfectly cook or reheat your snack while you focus on getting to the destination.

On the inside, it offers a non-stick aluminum cooking surface, allowing you to cook directly in the cooker. Though, we highly recommend using RoadPro Almunium Pans.

They are standard aluminum loaf pans. In practice, they make the portable stove much easier to maintain and clean in the longer run.

You can also choose other disposable loaf pans such as DOBI Disposable Loaf Pans.

These aluminum pans do help in keeping the food warmer for longer hours and make the food cook evenly because of their superior heat conductivity.

The Runner Up:

  • Smaller Size
  • 6ft Cord / Easier to Move
  • Heats up to 300 Degrees
  • Heat Resistant Case

  • Plug Unreliability
  • Uneven Cooking

GIDEON 12-Volt Microwave Stove stands as a runner up in this race by a very minimal margin. This portable stove is a perfect add-on to your car, truck, or caravan.

This mini microwave is 0.40 cubic feet in volume when compared to RoadPro Car Microwave, which is even smaller at 0.34 cubic feet.

The best part of this portable stove is its heat-resistance case. The portable stove case remained cool to touch at all times.

GIDEON car stove comes along with a 6ft cord that makes it convenient for camping and road trips. 

Just like RoadPro Car Stove, this also has an aluminum non-stick surface that can be easily wiped with a damp cloth.

This microwave can be used with any 12-volt power source and can heat up to 300 degrees at the comfort of your front seat.

One of the reasons this microwave stood as a runner up is because we’ve had numerous occasions where it took slightly longer in the initial warm-up. 

We noticed from various customer reviews on different retail websites about the plug unreliability. Several users complained that the plug was either broken or didn’t seat well into the lighter holder.

Nevertheless, after a ruthless run of our testing, we still believe it holds pretty well.
