Best Portable Microwave for Car in 2022 [Reviews]

Tired of eating a cold lunch at work or cooking food on a camp stove when you’re out in the wild? A portable microwave for car could help you keep your meals warm or diversify your dinner options.

Although different from traditional microwave ovens, portable microwave ovens for car are designed to cook food, reheat it, or keep it warm. Most units are compact enough for you to take in your office and the vast majority work with standard and 12-volt car plugs alike.

Now, are you wondering which is the best portable microwave for car to get your hands on? We spent hours researching and testing so that you don’t have to. Check our choices below to find the best portable microwave for you.

Can a portable microwave be used in the car?

Yes, a portable microwave can be used in the car, as long as it comes with a 12-volt plug or your car features a standard 120-volt outlet.

If your car doesn’t have a 120-volt outlet and the oven doesn’t come with a 12-volt plug, you could use an adapter to use a portable oven in the car. However, you must make sure the adapter features a transformer that allows you to use the oven safely.

Is it safe to use a microwave in the car?

Generally, it is safe to use portable microwaves in the car. These ovens are similar to lunch boxes but incorporate a hot plate. Depending on the model, the plate can heat up to 300°F and can defrost, cook, heat up or keep food warm.

The hot plate is set inside an insulated bag that keeps the oven’s exterior cool to the touch. This feature makes it safe to place the oven on an empty seat, plug it in, and cook your meal while you’re driving or hiking.

Aside from cooking in the car, you can also use a portable power generator to power the appliance.

When the cooking is done, you can simply unplug the unit and carry it to your office as you would do with a lunch bag.

What are the advantages of using portable microwaves in cars?

The main advantage of using a portable microwave in the car is that you can eat a freshly cooked lunch or warm up your food wherever you are.

These portable ovens are also ideal for students who don’t have space for a larger microwave in the dorm.

Moreover, a portable oven gives you the opportunity to cook your own meals in the dorm without breaking the rules, in case your dorm doesn’t allow students to use standard microwave ovens in their rooms – these portable units rarely consume more than 120 watts.

How to Choose a Quality Microwave for a car?

Portable microwave ovens are simple appliances, but there are a few things to check out before spending your hard-earned money.

Capacity

The most important thing to check when buying a portable microwave oven for the car is the capacity, especially if you plan to use the appliance while camping, to cook for larger crowds.

Most units on the market have a capacity of 1.5 to 1.6 quarters. If you need a larger unit, perhaps you should consider investing in a mini microwave oven.

Materials

There are two types of portable car ovens on the market: a softshell or a hard plastic bag. The softshell type looks like lunch bags and generally come with removable heat plates.

These models have a removable heat plate, which means that you can use the plate and the bag either together or separately.

Those portable microwave ovens with plastic cases may or may not have a removable heat plate, so you may not be able to use the lunch box separately.

Temperature

Another thing to check when buying a car microwave is the max temperature it reaches. Most portable microwaves for car reach temperatures up to 300°F. These models are perfect for those who want to cook raw or frozen foods.

Other units can only reach up to 130°F. The main advantage is their lower wattage, but you can only use these appliances to reheat foods.

Power levels

In addition to the temperature, you should also consider the power levels your oven has. Most portable car microwave ovens have two power levels: low and high.

Models designed to work as warm lunch packs may only have one power level. Those designed for campers can have six power levels or more. Consider your needs and decide which option is best for you.

Keep Warm Function

While all portable microwaves have a keep-warm function, you might want to check how long the unit keeps the food warm before turning off automatically.

Some of the best models can stay on for up to 12 hours, which is plenty of time for hikers and workers alike. Other models will turn off automatically after about three hours, and sometimes even less.

Power Source

Last but not least, check the power source. If you’re looking for a portable microwave for car, you might assume that all models come with a 12-volt plug. However, this is not always the case. Some models can have a regular wall socket plug.

The reason some car microwaves have regular plugs is that most cars nowadays are equipped with standard 110-120-volt sockets.

Some people may also need a portable microwave to use with a power generator, at a mountain cabin, or even in a tiny home.

Some portable microwaves only have 12-volt car plugs, whereas others come with both connector types. Again, consider your needs and pick what’s best for you.

With this in mind, let’s find out which are the best portable microwave ovens for car.
