Features

  • Portable Battery-Powered Heating: The adult lunch box offers battery power for meals on the go. Whether at work, in the car, or outdoors, you can heat your food without an outlet. Its 10,000mAh battery ensures one-time heating and lasting warmth, so you can enjoy hot meals anywhere

Description

Quick Tips for Using Your Lunch Box: 1. The top of the lunch box lid has a space for your fork and spoon, with a groove and a snap-on transparent cover. If the cover gets loose or falls off, just snap it back on. 2. The lid will only close properly when the meal container is inside. If you remove the container, the lid won’t close. Always make sure the container is in place before closing the lid. To Use The Lunch Box's Scheduled Heating Function: 1. Please first set the current time to match the actual time, then set the meal time. 2. For first-time use, please fully charge the device. Before each use, check the battery level. It should be at least 90%. 3. Please note that the lunch box must be powered on at least two hours before the scheduled meal time to activate automatic heating. Important Information About Battery-Powered Lunch Boxes: Our portable battery-powered lunch box lets you heat food without plugging in, so you can enjoy warm meals anywhere—at work, on a road trip, or during outdoor adventures. However, the large-capacity rechargeable battery adds extra weight, making the heater weigh 2.8 pounds, slightly more than the typical 2 pounds of standard electric lunch boxes that require plugging in. To Ensure Battery Longevity: 1. Only Use the Original Charger: Other chargers (even if they fit) are not compatible! Using any other charger may permanently damage your product. 2. Only Use the Original Battery: Other battery packs are not compatible. For Best Heating Results: 1. The display shows the temperature of the heating element, while the actual food temperature is usually lower to avoid overheating, which can cause burns and affect taste. Our lunch box is designed to evenly heat food to the ideal temperature after 2 hours. 2. Foods with higher moisture content heat more effectively. If moisture is low, adding a small amount of water or increasing the set heating temperature (note that this temperature refers to the heating element, not the food itself) can be beneficial. 3. Please consider contact with the container bottom: The device heats from the bottom, so it’s helpful for food or water to be in contact with the container bottom to capture heat. For irregularly shaped foods like chicken legs, adding a bit of sauce or a few drops of water can assist in gathering steam and heating the food more thoroughly. 4.If you want your food to heat more thoroughly or are worried it's not warming enough, you can turn up the temperature, program the meal time 20-30 minutes earlier, or do both for best results. 5.It’s recommended to use the original stainless steel container: For compatibility, please use only the original container. 6. You might want to use an insulated bag: Placing the device in an insulated bag, whether original or otherwise, can help retain heat and improve food warmth. Caution: The inner container is made of food-grade 304 stainless steel and contains nickel. Those allergic to nickel should avoid use.

  • HIGHLY RECOMEND!
Color: Green - Double-layer Bag Size: Large
This thing is awesome. Works as advertised. I used it once so far and I was very satisfied with the functionality and ease of use. Great for me working construction. I got tired of eating out all the time and this has freed me from that. I was expecting it to be bigger, bulkier and heavier. But im glad its not. Its a nice sleek design that is easy to handle and carry. I ordered the case and silverware and they are all of very good quality and seem durable. The container holds a good amount of food. Keeps your food warm long after it stops warming. Worked as advertised and I couldn't be happier with the purchase. It'll pay for itself in a week with the amount of food I was buying for lunches. Good for my diet and my wallet! Thanks a bunch highly recommend! ... show more

  • Game-Changer for Work Lunches!
Color: Blue Size: Large
I’m really impressed with this cordless electric lunch box. It heats up food much faster than I expected. The capacity is great too. It’s also extremely easy to clean. The removable tray lifts out smoothly, and the material doesn’t stain or hold onto smells. The display and buttons are simple to use, and the whole thing feels sturdy and well made. If you want something portable, reliable, and fast for work or on the go, this is definitely worth it. Highly recommend! ... show more

  • Best Lunchbox! It gets and keeps your food hot!
Color: Blue Size: Large
These lunch box is excellent! It gets the food really hot. I used it everyday! If you want to reheat your food in it, after you already ate once, it will not have enough battery for a second time in the day , if you want to reheat it there. Unless you charger it first. Its has a great design, it’s very user friendly, easy instructions and functions. Has a wide range of heating temperature. The sealing part it’s kind of tricky. In mine, I have to push it a little bit hard, to make sure that it makes the “click “ sound. It’s very easy to clean. It comes with your own utensils. I would recommend if you put big chunks of food, to cut it in little pieces, that way, the food gets hotter. ... show more

  • Heating lunchbox
Color: Green - Double-layer Bag Size: Large
The warming lunchbox is amazing, but make sure you give it enough time to fully warm or you’ll think it’s a waste. The downside of this product is the carrying bag. The top of this bag should be larger so that you can eliminate carrying 2 different bags.

  • Good little lunch box!
Color: Pink Size: Large
Great idea, but the timer function does not work. I've set it to turn on a few different times, but it never does. I have to manually turn on the heat. (If anyone has any suggestions, please let me know) The metal containers' size is generous - a grown man would be happy with the portion size. Add a little water or broth to make sure food doesn't dry out. Battery only lasts long enough for one heating session, so charge it as soon as you get home! The hinges seem thin and there's no way to fix that should one break, so keep that in mind. I love that it comes with utensils! They are sturdy, and we'll made. All in all, this is a great device if you dont have a microwave. ... show more

  • very efficient
Color: Blue Size: Large
The best lunchbox for your husband is rechargeable and you can set it to heat up an hour before your lunch break. You don't have to worry about microwaving or plugging it in; it's wireless and heats your food to the desired temperature.
