Important Usage Notes 1. Memory Function Application: The memory function is optimized for users with fixed daily routines. It works best when the lunch box is activated at the same time each day for a consistent meal schedule. Inconsistent daily timing may affect its punctuality. 2. Heating Temperature Specification: The lunch box offers an adjustable heating range of 170°F to 220°F. Please note that this temperature refers to the heating plate itself, not the final temperature of the food contents. 3. Heating Time Planning: A full heating cycle requires approximately 2 hours. To ensure your meal is thoroughly warmed, please plan ahead and start the heating process at least 2 hours before your intended meal time. 4. Battery Level Pre-check: Before each use, please verify the battery level. For a complete 2-hour heating cycle, it is recommended to ensure the battery is charged to at least 90% to prevent interruption. 5. Material Safety Notice: The inner pot is constructed from food-grade 304 stainless steel, which contains nickel. Individuals with a known nickel allergy are advised against using this product. 6. Optimal Heating Tip: As heating originates from the bottom, ensure full contact between the food and the container base for efficient heat transfer. For more even heating, consider adding a small amount of water to drier foods. 7. Compatibility Advisory: To ensure optimal performance and safety, please use the provided original charger and inner pot. The use of non-original components may lead to compatibility issues or suboptimal performance.

Must have for driver
Amazing product, we really love it! I bought this cordless electric lunch box especially for my husband, and it has been a perfect choice for his long trips.The size is just right compact but very practical. The functionality is excellent and easy to use. The storage capacity is enough for a full meal, which is very important when you are on the road. The insulating capacity is great, it keeps the food warm for a long time, and the food warms evenly and well.The build quality feels very solid, and the durability is impressive. It’s a very convenient and reliable product. Highly recommend it for anyone who travels a lot or works away from home!

Easy to use, great product!
I’ve been using this electric lunch box for a while now, and I’m really impressed. The battery lasts a long time — I can heat my food and it stays warm throughout the day. The food stays nicely heated without drying out, which is a big plus. The built-in timer is super convenient, so I can set it and forget it. It’s easy to use, easy to clean, and perfect for busy days when I can’t get to a microwave. Definitely worth it! 👍

Convenient heated lunch box
This heated lunch box is very convenient for work. It heats food well and keeps it warm without needing a power outlet. I like the option to set a specific mealtime instead of a countdown timer.The 1.3L capacity is enough for a full meal, and the removable divider is useful. The insulated bag and included utensils are a nice bonus. Overall, I’m happy with this purchase and would recommend it.

The product is reliable.
I’ve been using this EAST OAK cordless electric lunch box for a few days , and it has been a game changer for work. The battery-powered heating is very convenient, especially when there’s no microwave available, and the food heats evenly without drying out. I really like the memory and keep-warm functions — I can set it once and not worry about my meal getting cold. The capacity is perfect for a full adult lunch, and the build quality feels solid. Overall, it’s a practical and reliable lunch box that makes eating warm, homemade meals much easier on the go.

Looks are deceiving, unfortunately
extremely disappointed !Pros – I received this product in a timely fashion, the size of the meal tray is decent , and the packaging was nice including the insulated food bag.cons – Unfortunately none of the pros I encountered has anything to do with the working aspects of the product…because there really weren’t any other than it powers on * (asterisk bc it turned on but wouldn’t stay on long when unplugged)Received product and charged until full. Set the time, and timer . I started to heat and rise and I was excited, until it stopped heating higher after about 15 minutes. Topped out about 125 on the monitor roughly but when using infrared thermo gun and it was 112 deg. Added water to the tray to see how that’d heat. used food thermometer and no more that 115 deg. When unplugged, it lasts less than ten minutes. I’ve tried multiple times charging and trying to use unplugged and its obvious the battery is not good. everytime I unplug, it shows 6 min left. dies before 6 minutes. Say this was a defective battery…I’d understand and request a new battery, but plugged in, it doesn’t heat anywhere close to the settings. It displays up to 220 deg and heats to less than 100 deg from the max .The only thing I see this useful for is warming up a sandwich instead of having it cold because it’s not warm enough to make soup enjoyable.Will be returning this item once I get back from my work trip as I travel the country for work.

This heated lunch box is surprisingly lightweight and easy to carry, which makes it great for taking to work or on the road. It heats food evenly, feels durable, and has enough room to fit a full meal without cramming everything in. I really like that it comes with silverware and an insulated bag, so I don’t have to bring anything extra. Overall, it’s super functional, convenient way to enjoy a hot lunch anywhere.
