LunchOn: The Smart Portable LunchBox That Heats & Cools

 

 

LunchOn is designed for people who don't want to compromise on their meals. Whether you're at work, on campus, traveling, or outdoors, you can heat your food up to 80°C / 176°F or actively cool it with advanced Peltier technology. The portable 3-tier bento keeps every part of your meal organized, while a fork, spoon, and knife are built directly into LunchOn, so your everyday essentials are always with you. The detachable 25,000mAh power bank powers LunchOn and can also charge your devices through an up to 100W USB-C port. Control everything from the built-in display or mobile app and enjoy a true all-in-one meal system, ready wherever your day takes you.

 

 

Enjoy warm, satisfying meals wherever your day takes you. LunchOn's advanced thermoelectric heating system lets you heat your food up to 80°C (176°F), helping you enjoy meals at a comfortable serving temperature without relying on a microwave. Its portable design makes it easy to take to the office, school, road trips, outdoor adventures, or wherever life takes you. Simply choose your preferred temperature using the built-in display or the mobile app and enjoy fresh, homemade meals whenever you're ready.

Heating doesn’t have to start only when you’re ready to eat. While you’re setting up camp, finishing a hike, or simply enjoying time outdoors, you can start heating your meal from the LunchOn app and follow the progress on the built-in display. By the time you’re ready to sit down, your food can already be warming and waiting for you.

Outdoor plans shouldn’t mean settling for a cold meal. Whether you’re camping, hiking, having a picnic, or heading out on a road trip, LunchOn lets you bring a proper homemade meal and heat it when you’re ready. The additional bento containers give you room for fruit, vegetables, snacks, sides, or desserts, so you can pack more than just the main dish and have everything you need for a full meal outdoors.

No microwave line, no searching for cutlery. Heat your meal directly in LunchOn, grab the built-in fork, spoon, or knife, and enjoy your break when you’re ready. Everything you need for a warm meal is already with you, so your lunch stays simple, convenient, and on your own schedule.

LunchOn isn’t limited to heating or cooling food inside the bento containers. The temperature-controlled surface can also be used with compatible cups and containers, giving you more ways to use LunchOn throughout the day.

Keep your coffee or tea warm, cool a drink or dessert, or maintain the temperature of a small snack or side dish directly on the LunchOn surface. At your desk, LunchOn can also double as a charging hub, while the detachable 25,000mAh battery can be removed and used as a portable power bank for your phone, tablet, laptop, and other compatible devices.

 

 

LunchOn’s temperature-controlled surface gives you more flexibility from the same device. Heat your meal first, then use the base afterward to cool a compatible bottled beverage while you eat or relax.

One surface, two functions, so LunchOn can keep working even after your food is ready.

Takeout adds up faster than most people notice, and it’s not only about the money. When you rely on prepared meals every day, you often have less control over the ingredients, portions, and how your food is prepared.

Packing your own food doesn’t have to mean giving up convenience. LunchOn lets you bring the meal you actually chose, keep it at the temperature you want, and spend a fraction of what takeout can cost, without losing the grab-and-go convenience that makes takeout so tempting.

LunchOn uses Active Cooling Mode to cool your food down to -2°C / 28°F, making it ideal for fruit, salads, yogurt, vegetables, snacks, desserts, and side dishes throughout the day.

Once your meal reaches the selected temperature, Thermos Mode can help maintain it until you’re ready to eat. And because LunchOn is powered by a detachable 25,000mAh battery, the cooling system stays truly portable, so you’re not tied to a wall outlet or refrigerator nearby. Control it all from the built-in display or the app and enjoy cool, fresh food wherever your day takes you.

With Thermos Mode, LunchOn keeps your meal at the temperature you choose for as long as you need. Set your preferred temperature and duration in the app, and LunchOn automatically manages the heating or cooling to help maintain it until the time you selected.
That means your meal can stay warm or cool in the background while you work, travel, train, or relax, so it’s ready when you are.

Make the most of LunchOn’s cooling/heating surface. Use the Small ~400 ml or Medium ~800 ml bento container for fruit, snacks, sides, or desserts, while the remaining surface can help keep a compatible bottled drink cool beside it. One device, two uses, giving you more flexibility to enjoy your food and drink the way you want, whether you’re by the pool, outdoors, or simply taking it easy.

A cool meal can be just as important as a hot one. At work, LunchOn lets you keep foods like yogurt, fruit, overnight oats, salads, and fresh snacks at the temperature you prefer, so they’re ready when your break starts.

Instead of relying on a shared office refrigerator or eating food that has been sitting at room temperature, you can keep your meal with you, cool it when needed, and enjoy something fresh right at your desk.

Your workout shouldn’t dictate when or where you can eat. Pack your post-workout meal, salad, fruit, wraps, or other meal-prep favorites and let LunchOn keep them cool while you train. The detachable 25,000mAh swappable battery keeps LunchOn portable throughout the day, and if you need more time away from an outlet, simply swap in an extra battery.

When your workout is over, your meal is ready to go, and you don’t need to remember extra cutlery either. A fork, spoon, and knife are built directly into LunchOn, so everything you need to sit down and enjoy your meal is already with you.

LunchOn is built to move with you. Its compact design fits easily into your daily routine, whether you're heading to the gym, work, campus, or outdoors. Carry it on its own with the optional carrying strap/belt, or use the dedicated LunchOn Travel Bag for extra protection and easier transport.

LunchOn comes in five carefully selected colors, so you can choose the one that fits your style best. From clean and minimal to bold and expressive, each finish keeps the same premium design, smart functionality, and modular bento system. Pick your favorite and make LunchOn feel a little more yours.

 

 

The detachable 25,000mAh battery is what keeps LunchOn truly portable, but powering your meals is only half of what it can do. Slide it out in seconds and it becomes a high-capacity power bank for your phone, tablet, laptop, and other compatible devices.

On the battery itself, you get 2× USB-C ports, including up to 100W USB-C and up to 70W USB-C, plus 1× USB-A up to 20W. And you don’t even need to remove the battery to charge your devices. LunchOn itself also has 2× USB-C ports and 1× USB-A port, turning it into a convenient charging hub while the battery stays installed.

At approximately 92.5Wh, the battery capacity was intentionally selected to stay below the commonly used 100Wh threshold for lithium-ion batteries carried on passenger aircraft. That gives you plenty of portable power while keeping travel in mind. Airline rules can vary, so backers should always check their carrier’s requirements before flying.

LunchOn’s modular bento system gives you the flexibility to pack meals your way. It includes three removable bowl sizes: Large ~1,200 ml, Medium ~800 ml, and Small ~400 ml, making it easy to separate your main dish, sides, fruit, snacks, or dessert.

Optional removable dividers give you even more control over each meal, and all three bowl sizes are compatible with LunchOn’s heating and cooling base. Take only what you need, keep everything organized, and enjoy homemade meals wherever your day takes you.

Everything in LunchOn is designed around portability. With three separate bento containers and built-in utensils including a fork, spoon, and knife, everything you need for your meal stays together in one compact system. Pack it, take it, and enjoy your food wherever the day takes you.

 

 

LunchOn is designed to make cleanup simple. All removable ceramic food containers can be taken out completely, washed by hand, or placed directly in the dishwasher for a thorough clean.

The electronic base stays separate from the food-contact parts, so after your meal, simply remove the containers, clean them, and LunchOn is ready for the next one.

LunchOn gives you full control even when your phone isn’t nearby. The built-in 1-inch (2.54 cm diagonal) smart display shows the most important information directly on the device, so you can check what LunchOn is doing and make adjustments in seconds.

From the display, you can switch between Heating, Cooling, and Thermos Mode, choose your target temperature, use Timer Mode, check battery status, follow the current temperature and progress in real time, and access key device settings. Everything is designed to stay clear and easy to use at a glance, so the app adds convenience, but it isn’t required for everyday control.

The LunchOn app gives you complete control at your fingertips. Adjust heating, cooling, and Thermos Mode remotely, choose your preferred temperature, monitor battery status, schedule your meals, and use food recognition to estimate nutritional information and organize your daily meals with ease.

LunchOn’s app includes an AI-powered food recognition system designed to help you better understand what’s in your meal. Simply scan your food, and the app can identify the items and provide approximate estimates for weight, calories, carbohydrates, and protein.

The results are intended as helpful nutritional estimates, giving you a quick way to track your meals without manually entering every ingredient.

The app also brings your meal information together in one place, with calorie insights, meal tracking, food recognition, and personalized settings, making it easy to control LunchOn and keep an eye on your daily meals from a single app.

 

 

Every component inside LunchOn has been designed to deliver a reliable everyday experience. At its core, three advanced thermoelectric modules work together to heat meals up to 80°C (176°F) or cool food to help maintain its freshness, while Thermos Mode helps preserve your selected temperature for longer.

Power comes from a detachable 25,000mAh battery, giving you the freedom to enjoy LunchOn almost anywhere while also serving as a high-capacity power bank. It features two USB-C Power Delivery ports, delivering up to 100W and 70W, along with a 20W USB-A port to charge laptops, smartphones, tablets, and other everyday devices.

LunchOn can be operated directly from its built-in display or through the companion mobile app, allowing you to adjust heating and cooling modes, set your preferred temperature, schedule operation, monitor battery status, and access additional smart features. Every element is designed to work together, creating a portable solution that combines food storage, temperature control, and power in a single compact device.LunchOn started with a simple observation. Eating away from home often means choosing between expensive takeout, cold meals, or waiting for a shared microwave. We wanted to create a better everyday solution that gives people more freedom over how and when they enjoy their meals.

Our goal is simple: make homemade food easier to bring anywhere while helping it stay fresh and enjoyable throughout the day. LunchOn combines heating, cooling, portability, and smart features into one product, helping people save time, reduce everyday food expenses, and enjoy meals they've prepared themselves. We're excited to bring this idea to life and share it with our community.

Every LunchOn comes ready for everyday use with the main heating and cooling base, a detachable 25,000mAh battery, and a complete 3-piece bento system:

Large Bento: ~1,200 ml
Medium Bento: ~800 ml
Small Bento: ~400 ml

An adjustable securing strap is also included, designed to hold LunchOn together in different configurations. Use the complete 3-stage setup when you need maximum capacity, or adjust the strap for a more compact 2-stage setup when you’re carrying less.

Pack the configuration that fits your day, secure it, and take LunchOn wherever you go.
