DUPASUElectric Lunch Box Food Warmer: 100W Heated Lunch Box for Adults, 1.8L Portable Fast Heating Lunchbox Food Heater for Car, Truck, Work, Travel, Lonchera Elctrica Porttil 12/24V/110-230V

I purchased two different food heater lunch boxes. This one, the DUPASU at 100W, and a different one with item description COROTC Electric lunch Box that is 120Watt. Both work as advertised, but I like this one best.1. The OTHER box has confusing instructions, and if you don't read them, a person could easily make the mistake of adding the interior WHITE lid to heat. That would be wrong. Even the sticker makes it seem like you're to remove the hole coverings when heating instead of the lid. While foreign instructions are often not clear on many products, this DUPASU was easy to figure out.2. This DUPASU lunch box a comes with a lifetime warrantycard and easy way to register using your Amazon order #.I tested both against my Bluetti Solar Battery to see how many watts they would use in a power outage and how long it would take them to warm a small amount of food. They both can handle 1.8 L of food (~ 7 C) which is supposed to heat up in 20-30 minutes for both.I tested only 1 cup of water in both -- using the DC outlet, for exactly 10 minutes only.This one heated up 1 C of water to 113oF in 10 minutes and the amount of wattage used was exactly as described by the manufacturer for this short 10 minute period of time.The other one (higher wattage) heated up 1 C of water to about 115oF in 10 minutes, and didn't draw as many watts as advertised (115 vs 120) but it still heated up well.Summary: Both are good. Since I don't know much about these manufacturers, I'm happy keeping them both in case one just happens to not last as long as the other. Plan to use them in ER only anyway.

To start, I was skeptical of how well this electric lunch box food warmer would work. I found it difficult to believe something so small could actually heat food to an enjoyable temperature.Wow, was I wrong! I am extremely impressed with how well this food warmer works. It heats the food to the point where it needs to cool a few minutes before you can delve into your tasty hot cuisine. I have been using this warmer for 3 months without issue. In fact, I have been so impressed with this device that I purchased a second one. I can't believe how well they work, especially for the price point. As a side note, I have only used this connected to a 120V AC receptacle. I have not tried the 12V DC adapter, so I cannot speak to how well that works. Overall, I highly recommend this device, especially if you're looking for an alternative to using a microwave.

I bought this for my husband since he prefers my nutritious hot food instead of eating out at a restaurant with a limited lunch time at his work. The biggest meal of the day for us is lunch and since he is working, I wanted to be sure he got his hot meals at work. He will take a frozen homemade dinner out of the freezer the night before and put it in the refrigerator overnight to thaw. In the morning at work, the meal is still partially frozen. (Pictures is roasted chicken, mashed potatoes, and mixed vegetables).I break up the semi-thawed meal into chunks and put into the warmer and he takes it to work. At work, he plugs it in and by lunch time, it's fully thawed and nice at hot. The lid has a vent for heat to escape. It takes about 40-50 min for it to fully heat the meal thoroughly to sizzling smoking hot while the case on the outside is warm but not hot to the touch.There is plenty of space inside the warmer container! Enough for two dinner size meals (IMO). There is also an inner removable side dish container, like for a salad, that comes with it but you would probably take that out before heating the meal. I was very impressed with the heft and design of the elegant silverware that came with this in the top compartment of the warmer! It adds a classy touch and makes a lunch out of a warmer seem more classy. The warmer really seals airtight when the vent is closed. It comes with a great carrying tote.The cord is about 2.5-3 feet long. The lunch warmer box can sit on the desk or floor and doesn't take up much room. An extension cord or surger cord (one of those short cords with multiple sockets) may work just fine if you need extra length to the electric source outlet.If you are plugging into a normal wall current, use the 110-230V option and the standard wall plug cable (in the US).I really like this lunch warmer and I think it is a great buy! Wish I had one of these when I worked away from home!

It’s a great product. It heats up my food to a safe to eat temperature. Just give it 30 minutes before your break and it will be ready to eat.

This electric tiffin is fantastic! It heats up my food evenly and quickly, so I can enjoy a hot, homemade meal wherever I am. The compact design is perfect for carrying to work, and it’s super easy to clean. The compartments are well-sized and keep food separate without any leakage. It’s a lifesaver for busy days, and I love how convenient it makes meal prep. Highly recommend to anyone who wants warm meals on

Item is of good quality and heats up food evenly and very fast. My only complaint was that I didn't receive a lifetime warranty card in my box and so I'm unable to register mine for the warranty as other people have stated they have gotten in their box.
