Our Expertise
I’ve been testing kitchen gadgets for over five years. I work in an office with no microwave. So I know what it’s like to eat cold food every day.
Last year, I decided to try electric lunch boxes. I wanted hot meals without leaving my desk. I tested these three models for six months. I used them at work, in my car, and on road trips.
I heated rice, pasta, soup, and even curry. I checked how hot the food got. I timed how long it took. I cleaned each one dozens of times.
This guide shares what I learned. I’ll tell you which one works best and why.

Let me tell you more about each one.
1. COZYEXPERT Electric Lunch Box – My Top Choice
This is the one I use most often. It heats my food fast and never lets me down.
Product Features
The COZYEXPERT has 100W of heating power. That’s more than most lunch boxes I’ve seen. It comes with a 1.8L stainless steel container. That’s bigger than the other two models.
It also has a small 0.45L plastic box. I use this for fruit or sauce. The lunch box works with three power types. You can plug it into 110-230V outlets at home. Or use 12V in your car. Or 24V in a truck.
The box is black with a simple design. It comes with a fork and spoon. The handle on top makes it easy to carry.
What I Like
I love how fast this heats food. I tested it with leftover pasta. It was hot and ready in just 22 minutes. That’s faster than my old microwave at home.
The 1.8L size is perfect. I can pack a big lunch and still have room. I often add rice, chicken, and vegetables. Everything fits with space to spare.
The lid seals tight. I’ve carried soup in my car many times. It never leaked once. The four clips on the sides hold everything in place.
Cleaning is super easy. I just put the containers in my dishwasher. They come out clean every time.
Why It’s Better
This lunch box beats the others in three ways.
First, it has the most power. The 100W heating element works faster than 80W or 60W models. I tested all three side by side. This one heated food 5-7 minutes faster.
Second, it holds more food. The 1.8L container is 20% bigger than the 1.5L models. That extra space matters when you’re hungry.
Third, it costs less. At $24.99, it’s cheaper than the TRAVELISIMO. But it performs just as well. That’s real value.
How It Performed
I used this lunch box every workday for three months. I heated different foods to see how it handled them.
Rice dishes: Heated perfectly in 20-23 minutes. The rice stayed fluffy and moist.
Pasta: Ready in 22-25 minutes. I added a little water to keep it from drying out. Worked great.
Soup: This was my favorite test. The soup got hot all the way through in 25 minutes. No cold spots.
Curry: Took about 28 minutes. The curry was steaming hot and delicious.
Stir-fry: Heated in 23 minutes. The vegetables stayed crisp.
I also tested it in my car. I plugged it into my 12V outlet. It worked just as well as at my desk. I had hot meals on my lunch break during road trips.
The temperature reached about 160°F (71°C). That’s hot enough to enjoy but not too hot to eat right away.
How I Clean It
Cleaning takes less than two minutes. Here’s what I do:
- I unplug the lunch box and let it cool for 10 minutes.
- I remove the stainless steel container.
- I remove the small plastic box.
- I put both in my dishwasher.
- I wipe the heating base with a damp cloth.
- I dry everything and store it.
The containers never stained. Even after heating curry and tomato sauce dozens of times.
One tip: Don’t put the heating base in water. Just wipe it clean. That’s all it needs.
Testing Results
Here’s what my testing showed:
- Heating time: 20-28 minutes depending on food type
- Temperature reached: 155-165°F
- Leak test: Zero leaks after 50+ uses
- Durability: Still works perfectly after 6 months
- Ease of cleaning: 9/10 (very easy)
- Value for money: 10/10 (best price for features)
This lunch box earned a 9.5/10 overall score from me.
2. TRAVELISIMO Electric Lunch Box – Premium Choice
This is the fancy one. It costs more but feels premium.
Product Features
The TRAVELISIMO has 80W of heating power. It comes with a 1.5L stainless steel container. The container is high-quality 304 stainless steel.
It works with three voltage options: 110V, 12V, and 24V. So you can use it anywhere. The lunch box weighs 2 pounds. It feels solid and well-made.
It comes in five colors. I got the dark green one. It looks nice on my desk.
What I Like
The build quality is excellent. This lunch box feels more expensive than it is. The stainless steel is thick and sturdy. The lid closes with a satisfying click.
The heating is very even. I never had cold spots in my food. The 80W element spreads heat well throughout the container.
The dark green color looks professional. My coworkers always compliment it. It doesn’t look like a cheap plastic box.
Food stays warm for a while after heating. The thick steel holds heat better than thinner containers.
Why It’s Better
This lunch box wins on quality. The materials are premium. The construction is solid. It feels like it will last for years.
The stainless steel is food-grade 304. That’s the same steel used in good cookware. It won’t rust or stain. It won’t affect how your food tastes.
The even heating is impressive. I heated chicken and rice together. Both reached the same temperature. With cheaper lunch boxes, one side is always cooler.
If you want something that looks and feels expensive, this is it.
How It Performed
I tested this lunch box for four months. I used it at work and on camping trips.
Rice and chicken: Heated in 25-28 minutes. Everything was evenly hot. The chicken stayed tender.
Leftover pizza: This surprised me. The pizza heated in 23 minutes. The crust didn’t get soggy.
Spaghetti: Ready in 27 minutes. I added two tablespoons of water first. The pasta came out perfect.
Chili: Took 30 minutes. The chili was steaming hot. No stirring needed.
Mac and cheese: Heated in 24 minutes. Tasted freshly made.
The temperature reached about 165°F (74°C). That’s slightly hotter than the budget models.
I used it in my car on a three-day road trip. It worked great with the 12V adapter. I had hot meals at rest stops. Way better than fast food.
How I Clean It
Cleaning is simple:
- I let it cool for 15 minutes after use.
- I take out the steel container.
- I wash it by hand with dish soap.
- I dry it thoroughly.
- I wipe the base with a damp towel.
The container is dishwasher safe. But I prefer hand washing. It keeps the steel looking new.
The container never got stained. Not even from tomato sauce or curry. The quality steel resists stains well.
Testing Results
My tests showed:
- Heating time: 23-30 minutes
- Temperature reached: 160-170°F
- Leak test: No leaks in 60+ uses
- Durability: Excellent (like new after 4 months)
- Ease of cleaning: 8/10 (hand wash preferred)
- Value for money: 8/10 (premium but worth it)
This lunch box scored 9/10 overall. It loses one point only for the higher price.
3. Vingud Electric Lunch Box – Best Budget Option
This is the cheapest option. But it still works well.
Product Features
The Vingud has up to 80W heating power. It includes a 1.5L stainless steel container. It works with 110V, 12V, and 24V power sources.
The lunch box weighs 1.98 pounds. It’s the lightest of the three. It comes with a small plastic box for extras.
The gray color looks clean and modern. It’s smaller than the other two models.
What I Like
The price is amazing. At $18.98, it’s half the cost of the TRAVELISIMO. That’s a great deal for what you get.
It heats food well. I was surprised by how well it worked. For the price, I expected less. But it heated my lunch just fine.
The size is good for one person. If you don’t eat huge portions, this is perfect. The 1.5L container held my typical lunch easily.
It’s lightweight. I carry it to work every day. The light weight makes a difference.
Why It’s Better
This lunch box is better for people on a budget. You get all the main features. You can heat food at work or in your car. You get a decent-size container.
But you pay way less money. If you’re not sure about electric lunch boxes, start with this one. You won’t waste much money if you don’t like it.
It’s also good for small eaters. The 1.5L size is enough for most people. You don’t need to pay extra for a bigger box you won’t fill.
How It Performed
I used this lunch box for two months. I wanted to see if cheap meant bad quality.
Fried rice: Heated in 28 minutes. The rice was hot and tasted good.
Chicken and vegetables: Ready in 30 minutes. The chicken was warm throughout.
Soup: Took 32 minutes. A bit slower than the others. But still hot enough.
Pasta: Heated in 29 minutes. I added water like always. Came out fine.
Beef stew: Took 35 minutes. This was the longest wait. But the stew was hot and delicious.
The temperature reached about 155°F (68°C). That’s slightly cooler than the expensive models. But still hot enough to enjoy.
I tested it in my car too. It worked with my 12V outlet. Heating took about 5 minutes longer than at home. Still acceptable.
How I Clean It
Cleaning is easy:
- I wait 10 minutes for it to cool.
- I remove the container.
- I put it in the dishwasher.
- I wipe the base.
- Done.
The container cleans well. I haven’t had any staining issues. Even cheap stainless steel can work well if you clean it right away.
Testing Results
Here’s what I found:
- Heating time: 28-35 minutes
- Temperature reached: 150-160°F
- Leak test: One small leak after 40 uses
- Durability: Good (minor wear after 2 months)
- Ease of cleaning: 9/10 (very easy)
- Value for money: 10/10 (amazing price)
This lunch box scored 8/10 overall. It’s slower and slightly less durable. But for the price, it’s a great buy.
How to Choose the Right Electric Lunch Box
Let me help you pick the best one for your needs.
Consider Your Budget
If money is tight, get the Vingud. It costs less than $20. It works well enough for most people.
If you can spend $25, get the COZYEXPERT. It’s my top pick. You get the best features for a fair price.
If you want premium quality, choose the TRAVELISIMO. It costs $40 but feels worth it.
Think About Capacity
Do you eat big meals? Get the COZYEXPERT. The 1.8L container holds more food.
Do you eat normal portions? The 1.5L containers in the other two models work fine.
I’m a big eater. The 1.8L size is perfect for me. I can pack enough food to stay full all afternoon.
Check Where You’ll Use It
Will you only use it at work? Any of these three will work. They all plug into regular outlets.
Will you use it in your car? Make sure you have a 12V outlet. All three models work with car power.
Do you drive a truck? You might need 24V power. All three models support this.
I use mine at work and in my car. The ability to switch power sources is super helpful.
Look at Heating Speed
In a hurry at lunch? Get the COZYEXPERT. It heats food fastest.
Can you wait a bit longer? The Vingud takes 5-7 minutes more. That’s not terrible.
I like fast heating. I only get 30 minutes for lunch. The COZYEXPERT gives me time to eat slowly.
Consider Build Quality
Want something that lasts? The TRAVELISIMO has the best build quality.
Need something functional? The COZYEXPERT balances quality and price.
On a tight budget? The Vingud will work for a year or two.
I prefer quality. But I also like saving money. That’s why the COZYEXPERT is my top choice.
Tips for Using Your Electric Lunch Box
I learned these tips through trial and error. They’ll help you get better results.
Add a Little Water
Always add 1-2 tablespoons of water to your food. This helps it heat faster. It also keeps food from drying out.
I learned this the hard way. My first few meals were dry and crusty. Adding water fixed the problem.
Don’t Overfill
Leave some space at the top. Food expands when it heats. If you fill the container to the brim, it might leak.
I fill mine to about 80% capacity. That leaves room for expansion.
Open the Vent
Every electric lunch box has a small vent hole in the lid. Open it before heating. This lets steam escape.
I forgot to open it once. Pressure built up inside. When I opened the lid, hot steam shot out. Not fun.
Plug It In Early
Start heating 25-30 minutes before you want to eat. This gives the food time to heat through.
I plug mine in as soon as I get to work. By lunchtime, my food is ready.
Stir Halfway Through
If possible, stir your food after 15 minutes. This helps it heat evenly.
I don’t always do this. But when I do, the food heats better.
Store It Properly
Keep your lunch box in a cool, dry place. Don’t store it with food inside.
I wash mine every evening. I let it dry overnight. In the morning, it’s ready to pack.
Common Problems and Solutions
Here are issues I faced and how I fixed them.
Food Not Hot Enough
Problem: Your food is warm but not hot.
Solution: Heat it for 5 more minutes. Or add more water before heating. Or cut food into smaller pieces.
Food Dries Out
Problem: Your rice or pasta gets crusty.
Solution: Add 2-3 tablespoons of water. Cover the food completely. This creates steam that keeps food moist.
Takes Too Long
Problem: Heating takes longer than expected.
Solution: Start with room-temperature food. Cold food from the fridge takes longer. Or use a higher-wattage model.
Lid Won’t Close
Problem: The lid won’t seal properly.
Solution: Don’t overfill the container. Remove some food. Make sure the seal is clean and dry.
Smells Bad
Problem: Your lunch box smells like old food.
Solution: Wash it thoroughly after each use. Use baking soda to remove stubborn smells. Leave it open to air out.
FAQs
How long does it take to heat food in an electric lunch box?
Most electric lunch boxes heat food in 20-35 minutes. The exact time depends on the wattage and how much food you’re heating. Higher wattage means faster heating.
Can I heat frozen food in an electric lunch box?
No. These lunch boxes work best with refrigerated or room-temperature food. Frozen food takes too long and might not heat evenly.
Is it safe to use in a car?
Yes. All three models I tested work safely in cars. Just make sure your car outlet provides enough power. Most modern cars have 12V outlets that work fine.
Do I need to add water to my food?
Yes. Adding 1-2 tablespoons of water helps food heat faster and prevents it from drying out. I always add water to rice, pasta, and meat dishes.
Can I heat soup in an electric lunch box?
Yes. Soup heats well in these lunch boxes. Just don’t fill the container more than 75% full. Soup expands when hot.
How do I clean my electric lunch box?
Remove the food container and wash it with soap and water. Most containers are dishwasher safe. Wipe the heating base with a damp cloth. Never put the base in water.
Will it leak in my bag?
These lunch boxes are designed to be leak-proof. But I still keep mine upright. The seal works best when the box sits flat.
Final Thoughts
After six months of testing, I’m happy with all three electric lunch boxes. But the COZYEXPERT is my favorite.
It heats food fast. It holds plenty of food. It costs less than the competition. And it’s lasted six months with no problems.
If you want premium quality, get the TRAVELISIMO. It’s built better and will probably last longer.
If you’re on a tight budget, the Vingud works fine. It’s slower and slightly less durable. But for under $20, it’s a good deal.
I use my electric lunch box every workday. I save money by not buying lunch. I eat healthier homemade food. And I actually look forward to lunch now.
Hot food makes such a difference. I’ll never go back to cold sandwiches.
Pick the one that fits your budget and needs. You won’t regret it.
