How We Picked Top 7 12V Microwaves for Boats

A few months back, I had a long discussion with my team about microwaves for boats. As a team, we decided to find out portable microwaves that run on batteries because they suit the most on boats. After one week, my team was ready with 25 12-volt microwaves that we ordered online.

It took only 2-3 days for all microwaves to get delivered at my place. My team and I tested each 12V microwave for a boat for one week to know how good a microwave is and what it lacks. After two month, I asked my team members to prepare a top 5 or top 10 list.

My team came up with a top 7 list of 12-volt portable microwaves for boats that are good enough to consider for buying now. So, this is how my team and I did a thorough research & testing on microwaves for boats to suggest the best options for you.

Things to Check in a Microwave for Boats

Buying a new microwave is easy for experienced people and a bit complicated for first time buyers. If you want to buy a user-friendly microwave for a boat then you should check some important things in the microwave.

Now, I will explain the most important things that you should check in a microwave for boats before you decide to buy it.

12-Volt Microwave for Boat
12-Volt Microwave for Boat

Microwave Size:

The microwave you use in your kitchen is not suitable to use on a boat. Because it takes a lot of space and requires proper installation with venting. Therefore I suggest you to get a 12-volt microwave that is compact, lightweight and portable to fit anywhere on your boat.

At the time of purchase, make sure that the microwave is not too large. It should be compact enough to stay in a small corner of the boat when not in use.

Volt and Wattage:

As I said, you should pick a 12-volt microwave so that you can use it on your boat without worrying about power consumption. The 12V microwave for boats runs on a battery and uses 39-watts to 60-watts power.

You may have a 24-volt lighter port in your car/truck and a 12-volt port on your boat. So, you should get a 2-in-1 microwave that supports both the 12V and 24V ports so that you can use it in your car and on your boat as well.

Food Capacity:

Almost all 12-volt microwaves provide food capacity under 2-liters. The food capacity of a battery powered microwave lies between 1.4-liters to 2-liters but there is an exception i.e. Alfredx 12-volt microwave that offers 9-liters food capacity.

I have suggested 7 powerful 12V microwaves for boats from which you should choose the one that meets your needs. If you want a boat microwave with more food capacity then choose Alfredx 12V microwave otherwise go with a compact microwave with 1.5-liters capacity.

Cooking and Heating Time:

Some 12V microwaves are designed for heating up the food and not for cooking raw food. You should check the cooking time and heating time before you finalize a microwave for your boat. It is better to choose a microwave that heats up your food in 30 minutes than a microwave that takes more than 1 hour for the same task.

Carrying Handle:

The 12-volt microwaves are portable and lightweight but they should have a handle. You should check if your selected microwave has a handle on top or a shoulder strap for easy carrying. The handle/strap allows you to carry your microwave easily from home to the boat and anywhere you go.

In this way, you can find the best portable microwave for your boat by considering the important points I have shared above.

12-Volt Microwaves for Boat
12-Volt Microwave for Boat

Using a microwave on a boat is super easy and convenient. But you should have a 12-volt microwave for boats and follow the recommended safety tips that I am sharing here. Kindly, take care of following guidelines when you use a 12V microwave on your boat to avoid accidents.

[1] Keep It Stable:

At the time of reheating your food, make sure that the microwave is on a flat surface. The microwave must not move during the entire reheating process otherwise the food may fall out of container and create a mess.

Cooking or heating up food on an unstable microwave on a boat is dangerous. It can cause unwanted mess inside the microwave and can also damage the heating plate. So, you must keep the microwave steady during the heating up process.

[2] Use a Microwave-Safe Container:

You should carry one or more microwave-safe containers to your boat. I strictly advise to use a microwave-safe container for cooking/reheating the food in your 12V microwave food warmer. You can refer the user manual of your microwave to know which food containers, bowls and plates are safe for your microwave and which ones are not.

Always heat up your food in a microwave-safe container to avoid overheating, melting, burning and fire hazard issues in your microwave.

[3] Monitor the Process:

When you are using the 12V microwave on your boat, stay nearby it. Don’t leave the microwave as long as it is heating up your food. Once the food is heated, get it out and unplug the power cord. Then you can go away from the microwave as there is no risk.

If you leave the microwave when it is heating up food, it may overcook the food or burn it. You may forget about food inside the microwave and it can cause a fire hazard in the microwave. So, it’s better not to leave the microwave alone when it is in use.

[4] Stay Away from Water:

During your journey on the boat, make sure that the microwave or its cord does not touch the water. You should never operate the microwave with wet hands otherwise it can damage the microwave.

If you are using it heat up your soup, fill the container up to half so that it won’t spill out of it during the heating process. You should keep the microwave safe so that it does not come in direct contact with water at any cost.

[5] Keep in a Safe Storage:

When you are traveling on a boat, you should keep your microwave at a safe place. You should keep the microwave in a waterproof and leakproof bag when it is not in use. The bag will protect the microwave from unwanted damages so that it can last for years.

You should get your microwave out of the bag only when you want to heat up food. In order to keep the microwave safe, you should find a place for the microwave on your boat away from water and people.

By following the 5 important tips, you can keep your microwave safe on a boat and use it for many years. You should keep all safety tips in mind to save yourself from accidents and your microwave from getting damaged.
