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.

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.

  • Absolutely Awesome! A Total Lifesaver for Lunches!
Color: Black
This heated lunch box is just fantastic! The absolute best part is that it's battery-powered. I can finally heat up a proper hot lunch anywhere: at my job site, in my car, even outdoors! No need to hunt for an outlet. The battery has enough juice to heat my meal thoroughly once, and then it keeps the food warm for a good while after. I really love the smart timer feature too. You can set it ahead of time, and the lunch box automatically starts heating so your food is hot right when you're ready to eat. It even remembers your last settings, so you don't have to adjust it every time – so convenient! It holds a good amount of food – definitely enough for a filling meal. There's a removable divider, which is great for keeping things like your main dish and a side separate so they don't get mixed up. The lid seals up super tight with a silicone gasket. I haven't had a single leak, even when carrying soup. You can toss it in your bag without worrying about spills. Cleaning it is a breeze. The container, lid, divider, and even the fork and spoon (which come included!) can just go right into the dishwasher. No hassle at all. Speaking of included stuff, it comes with everything you need right out of the box: the fork and spoon, the divider, and even a nice insulated carrying bag with both a handle and a shoulder strap. Seriously, this is one of the best things I've bought for my workday. Forget about cold sandwiches! If you want hot meals on the go, get this – you won't regret it. It would also make a perfect gift for anyone who works out in the field or in an office without a decent kitchen. Giving this a solid 5+ stars! ... show more

  • Perfect for my husband’s work lunches
Color: Black
Got this for my husband so he could have hot meals at work without relying on a microwave. He LOVES it. He just plugs it in at his desk and it heats up his food evenly — no cold spots. The battery lasts surprisingly long, and it’s easy to use even for someone who’s not into gadgets. It’s also super convenient that the tray is removable and easy to clean. I usually prep his meals the night before and pack it all in. The portions are just right for a full lunch. If your partner or you are always on the go or working in places without kitchen access, this thing is a game changer. ... show more

  • Excellent lunchbox and worth every penny.
Color: Black
Excellent lunchbox and worth every penny. I've used this consistently for over two weeks now to get a good idea of how well it works. Gamechanger for lunchtime. Food is ready on time and piping hot, but not overcooked/heated. I previously had a plug in electric lunchbox, but found I am not always able to plug in my lunch box ahead of time at work or would plug it in only to have my lunch delayed causing the food to be overheated and soggy. This Lunchbox heats up food to be ready at the time of your choosing. I have had to take my lunch over an hour after my scheduled lunchtime, but food was still very hot, but not overdone. The case, fork, and spoon it comes with are quite good. I would not use the spoon to scoop ice-cream, but the silverware is very useable and will last a long time. Only drawback is that it is not suitable for quick heating. I have more than once forgotten to turn on the unit when loading my food in the morning. When using the heat now option, it does not get hot enough to heat up food to a suitable temperature within 30min (my typical lunch time). Food is warm and edible, but not hot. ... show more

I absolutely love this cordless lunch box! It’s easy to use, charges quickly, and keeps my food warm wherever I go — no microwave needed. Great for car trips, busy days, or when I’m out with the baby. The included utensils and compartments are also super handy. Highly recommend!

  • Like it!
Color: Black
My husband loves it, it heats the food great. It's great because you just program the food should heat up and when it's time for my husband to it and already hot. Before this buy I had bought my husband the one you had to plug in but he would always forget and he would have to get his food cold. I would recommend buying it. It is a little heavy. There are no spills and litte big, but durable. ... show more
