How to Choose an Electric Lunch Box

Choosing an electric lunch box might be a confusing task for some, given the many specifications and types of lunch boxes out there. Here we have a buying guide to help you pick out the best and most fitting lunch box according to your needs, schedule, mobility, and more.

① Make Sure It's Big Enough for All of Your Food

Make Sure It's Big Enough for All of Your Food

Perhaps the first thing to consider when picking out a lunchbox is the storage capacity. We recommend you go for a lunch box size based on your appetite and consumption. Some people expend a lot of energy during the day and might therefore eat more. If this is you, go for a big lunch box.

Regular-sized lunch boxes come in a range of capacities from one to 1.5 liters (4.2 to 6.3 cups). They should be able to carry a decently balanced meal. Some lunch boxes go up to 2 liters (8.4 cups) for those who tend to eat a lot in one go.

② Check Out the Voltage Output

Check Out the Voltage Output
If you're looking for a lunch box that works in your car, you'll need one with an adapter that runs on your car's 12-volt output. For semi-trucks, 24 volts may be required. Electric lunch boxes are often equipped with anti-skid bottoms to avoid spillage and tumbling, making your lunch box truly portable.

To save on electricity consumption, you can go for a lunch box that automatically shuts off when done heating or cooking. It's also advised to ensure that the plug is well-designed or waterproof for safety because you will be dealing with liquids and heat.

Keeping to the topic of power specifications, do check how long it takes to heat or prepare your lunch. Most electric lunch boxes take 20 to 40 minutes to operate and bring a meal to the ideal temperature, but it can take up to double the time if you start with very cold food.

③ Choose Between a Lunch Box That Warms or Cooks

Choose Between a Lunch Box That Warms or Cooks

Most electric lunch boxes will help you heat up your prepared meal to the perfect temperature for consumption. But did you know that some products can also cook food from a raw state?

For example, you can get a lunch box that cooks rice and steams food from scratch. You add water to the heating base then pile up the compartments with food. These lunch boxes can steam fish, veggies, and more, which is a healthy way of eating, too!

For a regular heating electric lunch box, the user is advised to pour in a bit of water beforehand if the cooked food came straight from the fridge in the morning. This will help soften up the ingredients, thus making them as good as fresh and ready to be enjoyed.

④ Find One That's Easy to Use

We're always on the lookout for the best features in any product, such as things that make them efficient and easy to use. For electric lunch boxes, it's recommended to consider the material for easy cleaning, the number of compartments, and the overall safety of the product.

Consider Easy-to-Clean Materials

Consider Easy-to-Clean Materials

Before you buy an electric lunch box, think about the cleanup. To make it easy for yourself, look for a lunch box whose container you can take out and place in a dishwasher. Plastic can be challenging to clean. It attracts oil and greasy and can get permanently stained by red and orange foods like tomato-derived sauces.

Meanwhile, stainless steel is generally easier to wash, rust-resistant, and dishwasher-safe. Aluminum is another material sometimes used in electric lunch boxes.

Get More Compartments for Variety

Get More Compartments for Variety

If you like a lot of side dishes or variety to your meals, look for a lunch box that accommodates dividers. They will allow you to keep your foods such as rice, vegetables, meat, and sauce in separate sections until they're ready to be eaten.

Some lunch boxes also come with separate containers for you to store foods that are not supposed to be heated up like salads, fruits, snacks, or desserts. Another variety to look for is a lunchbox with stackable compartments, which lets you carry your lunch upright.

Go for Safe and Environmentally-Friendly Options

Go for Safe and Environmentally-Friendly Options

Most electric heating lunch boxes use lower voltage, meaning more nutrients and moisture can be retained in the food compared to overheating in a microwave. The materials used are also safe, such as 304 stainless steel, which is both a non-toxic and environmentally-friendly option.

If you're looking for plastic, go for lunch boxes with food-grade PP, which is approved for food contact and doesn't present a health hazard to consumers. This information should be readily available in the product description.

Since we're dealing with heat and electricity, make sure it doesn't get too hot to the touch, especially if you're using it for kids or around kids. You can usually find this information in the reviews as users will often highlight if a particular model needs extra caution when handling.

Consider Some Useful Accessories

Consider Some Useful Accessories

Many electric lunch boxes come with utensils such as a spoon and a fork compactly stored in the lid. So you will never forget to bring your utensils with you.

Also, if you intend to purchase an electric lunch box that can be used in the car, make sure it comes with a car plug or you will have to buy one separately. Some manufacturers also include an insulated bag to make it easy for you to carry your lunch box.
