Heat/Cool meals with advanced Peltier technology | APP-controlled | Portable 3-tier bento |Detachable 25,000mAh power bank & 100W USB-C
If you are tired of eating lukewarm leftovers or waiting in line for the communal office microwave, a new gadget is upgrading the classic bento box. Launching on Kickstarter, LunchOn is a smart portable lunch box that integrates active heating and cooling. By replacing passive insulation with solid-state temperature control, it ensures your meal is exactly the right temperature the moment you sit down to eat.
PROJECT OVERVIEW
Name and Creator LunchOn: The Smart Portable LunchBox That Heats & Cools by LunchOn.
What It Is LunchOn is a portable, modular bento system equipped with bidirectional thermal technology. It functions as both a miniature refrigerator and a personal microwave, keeping food safely chilled or actively warming it to the perfect serving temperature.
KEY FEATURES
Bidirectional Thermal System Unlike simple heating coils or passive insulated bags, the base unit uses advanced thermoelectric (Peltier) modules to actively cool your food, alongside a dedicated heating element for warming.
Modular Bento Design The system includes three removable ceramic containers (Large 1,200ml, Medium 800ml, and Small 400ml) that let you separate mains, sides, and snacks. All three sizes are designed to work seamlessly with the temperature-controlled base.
Smart App Connectivity You can schedule heating or cooling cycles directly from the onboard display or a connected smartphone app, ensuring your meal is perfectly heated precisely when your lunch break starts.
Detachable Power Bank It runs on a removable 25,000mAh (92.5Wh) battery that falls safely under standard airline limits for carry-on luggage. It also supports a 100W USB-C PD input, allowing you to charge the battery independently or power the lunchbox directly from a wall outlet.
Easy to Clean The ceramic food containers are fully removable and dishwasher safe, keeping the electronic base completely isolated from messy food contact areas.
All-in-One Utility It features built-in utensils (a fork, spoon, and knife). You can even use the base without the bento containers as a smart coaster to keep your morning coffee hot or chill a canned beverage.
REWARDS
Kickstarter Pricing The campaign is offering early backers the chance to secure the LunchOn system at discounted promotional pricing before it hits standard retail channels.
Options Pledges generally include the core heating and cooling base, the modular bento containers, the integrated utensils, and the detachable power bank.
Delivery The campaign is successfully funding and will conclude on October 6, 2026. The creators will finalize manufacturing timelines and provide global shipping estimates to backers as the campaign wraps up.
CONCEPT
The core concept is Active Thermal Control. The creators at LunchOn believe that a traditional insulated lunchbox is fundamentally flawed because it merely slows down inevitable temperature loss. By engineering a portable solid-state thermal system, they aim to give commuters complete control over their meal's temperature, guaranteeing that hot meals stay hot and fresh salads stay crisp.
INSPIRATION
The project was inspired by the daily compromises made by millions of office workers, students, and outdoor enthusiasts who pack their lunches. The team recognized that people usually have to accept eating lukewarm meals, waste time navigating unsanitary shared office appliances, or spend money eating out. They set out to build a sleek, self-contained system that brings the convenience of your kitchen appliances directly to your desk or campsite.
