How to choose a heated lunch box?

This article would be less informative if there wasn't a buying guide to help you choose the best heated lunch box.

Choosing based on adapters

Electric lunch boxes are designed to enhance the enjoyment of eating in the easiest and fastest way. Therefore, you may want to buy those that come with different adapters.

To this end, many models include 2 types of adapters: 12V for in-car use and 120V for home use. Further on, you can also find some lunchboxes with a 24V power cable, especially for trucks. So check the power outlet you need before deciding which product is ideal for you.

Choose based on design material

If you are a health-conscious person, this factor is definitely the first thing you look for. It would certainly be a nightmare if you smell plastic in your food.

Obviously, consider opting for a unit that has walls designed from healthy and eco-friendly materials. Specifically, heating meals through a box requires materials like stainless steel. For your safety, this is a food-grade material that is free of BPA.

Choose based on ease of cleaning

The best heated lunch box should make your life easier in terms of maintenance. Obviously, it is not recommended to wash the entire body of the device with water or dip it in liquid to clean it. Besides, it is a rather tiring maneuver. For better maintenance of your box, consider choosing a model that has removable containers that are dishwasher safe. Fortunately, stainless steel and plastic are easy to clean.

Choose based on convenience and practicality

Another thing to consider is the practicality of your lunchbox, which is mostly dependent on its design. Here, we are talking about the features that can make the jar easier to use. For example, it should have a heat-resistant carrying handle. This way, you could use it safely without unexpected burns.



Furthermore, the best warming lunch box should include storage for cutlery. Better yet, some brands like Healthy Lunch go above and beyond by offering you accessories like:

  • Forks;
  • Spoons;
  • Knives, etc.

You can install them in a built-in storage space in the lunchbox, which increases its convenience.

Apart from that, some manufacturers also offer a cooler bag that you can carry anywhere you want. It also keeps your box safer and retains the heat inside.

Choose based on storage capacity

Generally speaking, the normal capacity of an electric food box can vary from 1 to 1.5 liters. Besides, this is a capacity that is ideal for one person's portion. However, we suggest that you rely on your consumption capacity to choose. For a hard worker, the best hot jar should hold enough food to eat for an entire workday.

Choose based on water resistance

A good lunch box should be free of spills or leaks so that everyone can carry it. The heated lunch box is no exception to this rule. To avoid any unpleasant surprises, look for one with a rubber seal and good sealing ability. The goal is to seal your food safely inside without causing a mess.

Choose according to heating performance



Everyone has a limited lunch break. Therefore, it is necessary to get an appliance with fast performance. In addition, it must heat the meal evenly to provide better cooking. On the market, there is a variety of products that promise crazy performance. It should be noted that not all of them are accurate, as some of the information is hidden in advertising.

Otherwise, a quality heating box can cook for 20 to 30 minutes maximum and reheat in 5 minutes. You can also check the heating time on the description or manual after purchase.

Choose according to the number of compartments

The more compartments your warming lunch box has, the more different types of food you can store in it. If you want to prepare a full lunch with many dishes, you should look for ones that have more than one compartment.

This will allow it to separate your food, such as vegetables, meat or rice, into different parts. Some versions also include tiers so you can eat more comfortably.


How to properly operate a heated lunch box?

In order to have the tastiest lunchboxes, you need to know how to properly operate your electric lunchbox. Here are a few steps to get it working properly to ensure your lunch is perfect for serving.

  • Step 1: Place the food inside the container.
  • Step 2: Add a little water to the food to make it softer after heating.
  • Step 3: Close the lid and plug it in.
  • Step 4: After finishing heating/cooking, remember to unplug the appliance before using it.

In addition to these simple steps, you should also take certain precautions when using the unit:

  • Open the steam exhaust cover before heating, as the steam locked inside the box will damage the food.
  • Always leave your lunch box upright to avoid leaks or spills.
  • The unit may still be hot after you unplug it, so let it cool down before touching it again.
  • Always unplug your lunch box before cleaning it.
  • Never immerse the body of the unit and the power cord in water.
  • Do not place your lunch box in the microwave to heat it up or in the refrigerator to keep it cold.
