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.

Really like this lunch box. It heats food well and is super convenient if you don’t have a microwave. The size is good and it’s easy to use. I like that you can just turn it on and it warms everything evenly. It does take a little time to heat up, so you need to plan ahead. But overall very useful and worth it It helps a lot for me during long day at tournaments ... show more

  • HIGHLY RECOMEND! HIGHLY RECOMEND!
Color: Dark Green Size: Large
This thing is awesome. Works as advertised. I used it once so far and I was very satisfied with the functionality and ease of use. Great for me working construction. I got tired of eating out all the time and this has freed me from that. I was expecting it to be bigger, bulkier and heavier. But im glad its not. Its a nice sleek design that is easy to handle and carry. I ordered the case and silverware and they are all of very good quality and seem durable. The container holds a good amount of food. Keeps your food warm long after it stops warming. Worked as advertised and I couldn't be happier with the purchase. It'll pay for itself in a week with the amount of food I was buying for lunches. Good for my diet and my wallet! Thanks a bunch highly recommend! ... 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 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

  • Electric Lunch Box
Color: Onyx Black Size: Large
This cordless electric lunch box has become an absolute lifesaver for our family. My son is an athlete, and we often travel to his competitions, spending long days on the road or at sports venues where finding healthy, warm food is almost impossible. This heated lunch box allows me to bring homemade, nutritious meals and warm them up easily without searching for a microwave. The automatic heating works perfectly, the food heats evenly, and the portion size ( is just right for an active teenager who needs proper fuel. For any parent of a young athlete—or anyone who spends a lot of time traveling—this is a truly essential product. Being able to feed my son warm, healthy, home-cooked food wherever we are gives me real peace of mind. Excellent quality, very practical, and absolutely worth it! ... show more

  • Really good purchase, worth it!
Color: Black Size: Large
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

  • Battery Fail, but great while it worked.
Color: Black Size: Large
Basically a timed slow cooker. Set the time when you want your hot lunch, set your local time, set your temperature and it will slowly heat up 2hrs prior to your lunch time. Hot food when you are ready. The failing point is the battery and the sudden drop of charge. This is all based on the battery indicator on the device. After 3 weeks of use and it being fully charged, it would suddenly drop to 5%. When I plug it in, the indicator would jump to 55% after 5 minutes of charge. The charger is 9v 2amps which tells me there is no way it charges that quickly. It would do this every time it is charged and ready for the day. I am returning it because of the battery (the whole point of the device). If I could use it without the battery and just the plug in, then I would, but I work in construction. ... show more
