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.

  • 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 EAST OAK Cordless Electric Lunch Box works great in this regard, it heats up several cartons of formula quickly and evenly and has enough battery power for several meals. This is ideal when I'm away from home or traveling. I just wish they would allow it on commercial airlines! ... show more

  • Perfect cordless solution
Color: Black Size: Large
I have previously purchased two electric lunch boxes that could heat food either by plugging them into a wall outlet or a car's 12V charger. However, since my wife’s job doesn't allow her to heat her food using a car or a power grid, I decided to look for alternatives so she could enjoy a warm lunch. At first glance, this has been a great purchase. It feels well-built with sturdy plastics and has some weight to it, likely due to the large battery. The food container isn't huge, but it's sufficient for an average person. It heats up relatively quickly—in about 30 minutes, your food is hot if it's a standard portion. I consider this a good buy, especially for those who have no other way to heat their meals. ... show more
