This includes the heated lunch box, which is one of the most sought-after products on the market.

There are a variety of them, but the best lunch box heater is the one that fits the capacity of your choice. It should also match the power source you have, including a mains, car or truck.

To help you make the right choice for your needs, this article will present you with a comparison of the meal warmers currently dominating the market. And to broaden your knowledge, a buying guide will be made available to you. So don't waste any time and let yourself be excited by the originality of the products.



What is a lunch box ?

Basically, a lunch box is a lunch box that allows you to keep food warm. Contrary to an insulated airtight box, this one does not only keep the heat. It manages to produce heat to reheat and steam food without drying it out. Technically, the hot box for meals is powered by a wired plug or a car or truck adapter. You can recognize them by their ultra precise voltage: 220v, 12v and 24v. These clever power sources rely on water to create steam at the bottom of the lunch box.

It's super simple to use: just put the food in and then plug in the lunchbox for 1 hour or 30 minutes before lunch. A light is usually integrated on the device to ensure that it is turned on. The heated food box is also very easy to clean. Simply take out the metal bowl to wash it with its lid.

How to choose a warming box for meals?



There are two main factors that should define the choice of your heated lunch box:

  • Where you plan to use it;
  • the capacity you need to hold your food.

In addition, there are a few other features to keep in mind as you evaluate your options.

Choosing your warming food box based on its power source

Heated food boxes usually come with different types of plugs. Some models are specifically designed for home use with a standard wall outlet (220v). At the same time, others offer cigarette lighter plugs for cars (12v) and 12v cables for the trucker lunchbox.

Depending on where you want to use your heated food box, choosing the power source becomes easier. This way, you are sure to keep your meals warm at any time of the day. However, be sure to use each energy source according to the designer's instructions. This will prevent you from discharging your vehicle's battery quickly.

One is also tempted to mention the subject of the heating time of the device. However, this remains a subjective criterion. While some models claim to heat up or cook in 20 minutes, others promise a cooking time of 15 minutes. Here, the most important thing is to have a rechargeable lunch box heater capable of ensuring a 360° temperature uniformity.

Choose your lunch warmer according to its container

The best lunch box heater should come with a container. The latter should serve as a jar offering the possibility of eating hot food directly from the dish itself. Moreover, this container should be designed with a double wall of stainless steel. This is a material that will not stain or absorb the flavor or smell of your hot food. Best of all, it's usually dishwasher safe for no-hassle cleaning.

Some electric hot boxes also have internal compartments to separate liquid and solid foods. A little further down the line, you can even find models with storage space for kitchen utensils.

Choosing a food warming box according to its storage capacity



On the market, heated lunch boxes vary in volume from about 500 ml to 1.5 liters. So you have a choice when it comes to finding one that suits your lifestyle or diet. At home, it's easier to control what you eat. You can choose a meal box of about 800 ml for your domestic needs.

However, if you are a nomadic worker, you will need a 1 to 1.5 liter hot food container. In general, more space is better than less. Whatever the capacity of your container, it should also be easy to heat and stir food. There is no need to have a stainless steel lunch box that is unable to promote an even temperature distribution.



It's obvious: a heated lunch box will never be as fast as a microwave oven. However, if you are looking to enjoy a hot meal wherever you are, the heated lunch box is useful and practical. Plus, it won't dry out your food like a microwave would and can fit your lifestyle. Whether you're working in a local office or on a construction site, the lunchbox blends in with any decor. Technically, it would be difficult to define one model as the best warming box. However, for excellent value, we recommend the Lunch Box Electric Green (Car/Home).
