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. Manufacturer Contact Information 1-833-EAST-OAK (USA) Mon-Fri: 9:00 am - 5:00 pm PST/PDT

Great Cordless Lunch Box for Work and Travel
Color: Black Size: Large
This cordless electric lunch box is very convenient and easy to use. It heats food evenly and keeps meals warm without needing to stay plugged into an outlet, which makes it especially useful for work, road trips, or anywhere without easy access to a microwave. The size is good for a full meal, and the container feels sturdy and well made. It is also fairly easy to clean after use. Overall, a practical and convenient option for bringing hot meals on the go. ... show more

Absolutely Love It! Wish I Bought It Sooner!
Color: Black Size: Large
I’m absolutely thrilled with this purchase! I used to wake up at 6 a.m. to get my husband ready for work, heat up his food, and pack it into a thermos. Now I prepare everything the night before, and he takes the lunch box with him to work. In the morning, he simply sets the timer, and by lunchtime his food is hot and ready to eat. This has made our mornings so much easier! The battery lasted for two days on a single charge, which I think is perfectly reasonable. The food container feels sturdy and well made. The food heats evenly without burning or sticking to the bottom, and the container is very easy to clean afterward. I honestly love this lunch box and only wish I had bought it sooner. My husband gets to enjoy a hot meal at work, and I get a little extra sleep in the morning. Definitely a 5-star purchase! ... show more

Being able to heat up food anywhere without searching for a wall outlet is a total game-changer. You just set the timer in the morning and completely forget about it until lunch.

Handy for work when there’s no microwave
Color: Black Size: Large
I picked this up because my office microwave is always busy. So far I’m pretty happy with it. Battery lasts through my workday. I prep food in the morning, set the timer, and it’s warm by lunch. Controls are simple to figure out.The inner tray comes out so cleaning isn’t a hassle. It even includes utensils and a carry bag. Do keep in mind it doesn’t heat instantly, you have to start it early. Overall solid for eating hot food away from home. ... show more

Love this lunch box!
Color: Onyx Black Size: Large
I take it to work every day, and it’s so convenient to have hot food without hunting for a microwave. The battery heats my meal perfectly, and the timer lets me set it ahead of time. The 5.5-cup size is just right for a hearty lunch, and the divider keeps my main dish and sides separate. No leaks thanks to the tight seal, so I can toss it in my bag without worry. Cleanup is a breeze—just put the container in the dishwasher. The insulated bag has extra room for snacks or a drink. It’s simple, practical, and makes my lunch breaks much more enjoyable. ... show more

Works great for a kids lunchbox who wants hot food
Color: Dark Green Size: Large
So far so good. I have an extremely picky eater. I had tried so many different things for him to eat his lunch. Nothing would keep it warm let along hot enough for him to eat. This lunch box so far has worked perfect for us. One of the things I can always get him to eat is what we call dinosaur eggs. It’s the oatmeal with candy dinosaurs in it. What I do is freeze milk (in a soup portion container I have bought on Amazon) and the put the divider in and make a kind of bowl with aluminum foil. Not sure if that’s recommended, but it keeps most of the liquid in a smaller space so the oatmeal gets cooked. It’s kind of heavy for a kid, but thankfully has a shoulder strap my son uses to carry it into lunch. I bought the carrier bag that also has a stop storage so I can put the rest of his lunch in. This has been a great solution on a kid who is in elementary and doesn’t have a way to warm up food in a microwave. ... show more

Holds a ton, small box
Color: Black Size: Large
I have two of these, one for my husband and one for my son. They love having a hot meal ready at lunchtime. Nothing burns, food is heated evenly. The stainless steel inner compartment is large, easy to clean and does not stain or hold odors. The inner container has a lid, and the unit itself snaps closed. We have never had anything leak or spill, and odors do not escape during the heating process. The unit comes with a carrying bag. The entire unit is lightweight and no bigger than an average lunch bag. I have black and navy, both of which look masculine. This is a very important feature for the 19 yr old that is building bridges for a living! ... show more
