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.

  • Simple and convenient to use
Color: Black
I recently started using a heated lunch box, and it has been a game changer for me at work. Since we don’t have a microwave in the office, I used to be stuck with cold meals or spending extra money eating out. I can enjoy a hot, homemade lunch anytime. The convenience is the best part, just plug it in minutes my food is warm and ready to eat. This design is simple, easy to carry, and doesn’t take up much space in my bag. I also like that the battery lasts a long time, so I don’t have to worry about charging it constantly. Overall, it’s a great solution for anyone who wants hot lunches on to go, without relying on a microwave. ... show more

  • Best Lunchbox! It gets and keeps your food hot!
Color: Blue
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

I really like this EAST OAK cordless electric lunch box! It’s so convenient to have a battery-powered food warmer that I can take anywhere without needing to plug it in.

The automatic heating works smoothly just set it up and my food is ready in a short time, evenly warmed through. The build feels sturdy and easy to clean, which makes it great for everyday use. Perfect for work, travel, or even picnics. Definitely worth it! ... show more

  • Quality, colour and convenient size

Really beautiful colour and quality. Didn’t expect it to work so well right out of the box. Heats food fast and evenly, no cords needed. Compact, easy to clean, and really handy for taking meals anywhere. I’m happy

  • 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

  • Heating lunchbox
Color: Green - Double-layer Bag
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.

  • Handy, functional and easy to use
Color: Blue
I purchased this for my boyfriend as he has been wanting something to keep his lunches warm or the ability to rather warm them 30 minutes before he eats. I purchased this particular one because it was exactly like the ones that cost a lot more and in his opinion, he feels that this is just as good. Make sure that you use a little bit of moisture to keep your meal from drying out other than that, very happy with its results and functionality easy to put the metal compartment into the dishwasher. Battery is adequate for two days. ... show more
