I love it. This keep my food ready to eat Read more
This is a great way to get warm food away from it all. IT can be powered by the battery or plug. It can heat your food even when cold to a nice tasty temp. It might take it some time and there is a little learning curve but once you get to know it, it becomes a great device to have for warm meals. It has a carrying bag and utensils included. The main dish is dishwasher safe so clean up is a breeze. The screen and timer is easy to set and see. The entire lunch box is built well and is suitable on the job site. The lids are nice and they seal tight without anything spilling all over. This has a good capacity and works like it should even after multiple uses every week. It might seem a little pricey but you get a quality made box with good solid parts that works and should last. Read more
This thing is great and saves money. This is perfect for having a good hot meal at work without spending a bunch of money. I ordered this basically for bringing leftovers to work and not have to use a microwave. This heated lunchbox is a great solution. Very easy to use with decent instructions. Works well for spaghetti, lomein, and even burritos. I like the burritos because they leave no mess. I wrap a hot burrito in foil, keep insulated and warm, and then start heating 20 minutes before lunch. I was very impressed with how well it worked. When I did put some lomein, it worked equally well and was easy to clean, just rinsed it and put it in the dishwasher. The include utensils are self contained work great. The carry case has room for extras such as a slice of fresh bread and a napkin. I really love this device and would have given it five stars except for one flaw, there is no power indication to let you know how much power you have or when it is charged. It really needs a way to display what the power level is. Still I do love it and feel it is worth the price, especially considering what I save by being able to bring good food to work and not have to get fast food or other expensive restaurant food. Plus my food is healthier, so great for my food plan. Read more




We have an older version, different maker of portable heated lunch box and this is soooo much better. That one you had to plug in and let it warm so cordless was not quite true. This one is actually and it works wonderfully PLUS it's charged up with a USB-C so it's actually super functional and fantastic. We haven't used it for anything but lunches going back and forth to work but I'm excited for the idea of being able to travel and camp with this ... so many uses!! it's light and easy to carry, warms food perfectly and pretty quickly and is perfect size for leftover lunches. Yes it's a bit more expensive than many out there but for the quality and portability -- it's worth it. Read more
This Oaktiv heated lunch box is super handy for hot meals on the go. The 33.8 oz size is perfect for a hearty lunch, and the rechargeable design means I don’t need access to a microwave or plug. The built‑in timer makes heating easy and predictable, and it warms food evenly. The carrying case is a nice touch for transport, and overall it’s easy to use and clean. Great for work, travel, or road trips — just wish the battery lasted a bit longer on one charge and that the power button was located differently so the bag wouldnt accidentally turn it on. 3 times so far, I put my food in the bag and went to work. Got it out to turn it on so it would be ready in an hour, and it was already on and food was hot. Ruined my food. Read more

The same company that made camping tolerable for me with their tent and sleeping pad has now solved another problem I didn't know had such a good solution - hot meals anywhere, anytime. Performance: The 45W cordless heating is surprisingly powerful and efficient. The timer function means you can set it and forget it without worrying about overcooking or draining the battery. It heats food evenly and actually gets meals hot, not just lukewarm like some food warmers. The 33.8oz capacity is perfect for a full adult meal without being bulky. Quality: This is built with the same attention to detail and durability I've come to expect from Oaktiv. The rechargeable battery holds a solid charge, the heating element is reliable, and the included carrying case protects it during transport. Construction feels robust enough for daily use or throwing in a camping kit. Overall Impression: Whether you're camping (pairs perfectly with their tent setup), working on job sites, or just tired of cold lunches, this heated lunch box delivers. The cordless design means true portability - no searching for outlets or dealing with car adapters. This completes the Oaktiv camping trinity - great tent, comfortable sleeping pad, and now hot meals. They've clearly figured out how to make outdoor living comfortable. Read more
