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

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.

  • Hot and fresh meals on the go!
Color: Black Size: Large
I recently purchased this cordless heated lunch box and I couldn’t be happier with how well it performs. From the very first use, I was impressed by how quickly it warmed up my meal to just the right temperature without needing a microwave or plug-in power source. The 5.5-cup capacity is perfect for a hearty lunch — I can easily fit a full meal with proteins, sides, and even a little dessert without any struggle. The removable tray divider is a thoughtful touch that makes meal planning much more enjoyable and keeps everything neat and separated. Clean-up is a breeze too, since the container and accessories are dishwasher safe. Another big plus for me is how portable and convenient this lunch box is. It’s lightweight and battery-powered, so I take it everywhere — to work, on road trips, and even to picnics — without ever worrying about finding an outlet. The smart timer function ensures my food is heated right when I want it, and the memory feature means I don’t have to fiddle with settings every time. I especially love that it keeps food warm for a good while after heating, so I can enjoy it at my own pace. Overall, this lunch box has truly elevated my daily lunch routine. It’s clear that thoughtful design went into building a product that’s both practical and reliable. The leak-proof lid gives me confidence to toss it in my bag without stress, and the included utensils are a nice bonus that show attention to detail. Whether you’re a busy professional, a traveler, or just someone who prefers hot meals on the go, this lunch box delivers excellent performance and value. I highly recommend it to anyone looking to enjoy warm, home-cooked meals away from the kitchen! ... show more

Bought this for my kids for them to bring leftovers to school. They hate school lunch and won’t eat a sandwich so this made things much easier this year. They are able to set a time on it and it begins heating up their lunch ahead of time and is ready to go when they are ready to eat. They both love their lunch boxes! ... show more

  • Works quickly, evenly heating cartons of formula, sufficient battery life for several meals.
Color: Black Size: Large
I have unique need that this EAST OAK Cordless Electric Lunch Box fulfills quite well. Due to an inability to swallow, I am restricted to a liquid diet via a feeding tube. This liquid diet, a all purpose formula, is best tolerated when warmed to body temperature.

This is ideal when I'm away from home or traveling. I just wish they would allow it on commercial airlines! ... show more

Easy to use and does what is meant to do. 175 is good temperature and holds more than enough food definitely worth it plus it holds its utensils. The only thing is, i wish it would've come with a little bit bigger bag cause only the lunch box fits you can't put snacks or drinks inside
