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 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. It’s recommended to use the original stainless steel container: For compatibility, please use only the original container. 5. 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. E1: If a device fails to power on, you can force reset the embedded controller (EC) using the following steps: 1. Remove the four screws. 2. Pry open the left-side clip. 3. Pry open the right-side clip. 4. Remove the battery cover. 5. Pull out the battery connector. 6. Disconnect the battery connector. 7. With the screen black, press the power button several times. 8. Reassemble. 9. Repair complete.

Product Care Instructions: The display shows the heating element temperature while keeping food slightly cooler for safety. Moist foods heat most effectively, so adding water to dry items may help. Always ensure food contacts the container base directly, adding sauce or water for irregularly shaped items. To heat faster, increase the temperature setting or begin heating 20 to 30 minutes earlier. For optimal results, use the original container with an insulated bag and allow approximately 2 hours for thorough, even heating, To maintain battery life, use only the original charger and battery. For scheduled heating, first set the correct current time, then your meal time. Fully charge before first use and keep battery above 90 percent for each use. The lunch box must stay powered on at least two hours before meal time to activate heating. The lid includes utensil storage with a snap on cover that can be pressed back if loose. The lid only closes when the container is properly inserted.

  • Easy to use
Color: Pink
Love this lunch box! It heats my food perfectly without needing to plug it in, which is super convenient at work. The size is great for a full meal, and the divider keeps everything separated. Easy to use and easy to clean. Definitely worth it!

  • Good little lunch box!
Color: Pink
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

  • Hmmm…What happened?
Color: Pink
Update: The second one that I had purchased along with this one has now stopped holding a charge, even after charging it overnight to 100%. Now it’s too late for me to return the second one. I really wanted to give this item a full 5 stars, but I can’t. I purchased two (one for each of my kids to use at school). I’ve used them both a total of 3 times since purchasing, and one of them has already started to malfunction by not keeping a charge, even when fully charged before use. I had high hopes for these devices and thought I had hit the jackpot, but obviously not. I am returning the item. Not sure yet if I will order again or not. ... show more
