Heated Lunch Box for Adults with 16,000 mAh Battery and Five Heat Levels Cordless and rechargeable: keeps a meal warm up to 5 hours, no outlet needed Even bottom heating: heat spreads across the base instead of pooling Five heat levels: gentle warming for leftovers or full heat for a stew Built for the day out: desks, commutes, picnics and outdoor trips 33.8 oz capacity: room for a full main meal in one container A cold desk lunch is a small daily disappointment. This heated lunch box for adults carries its own power: a 16,000 mAh rechargeable battery warms your food wherever you are, so a portable food warmer for work becomes a genuinely hot meal on a building site, a train or a campsite. Heating happens from the base, spreading warmth evenly through the container rather than scorching one corner. Five adjustable heat levels put the temperature in your hands, and once it reaches temperature this electric lunch box holds food warm for up to 5 hours without water. The 33.8 oz capacity takes a full main meal instead of a snack, and the compact white body slips into a rucksack. A full charge takes about 8 hours, so most people charge it overnight and pack it in the morning. Key Features 16,000 mAh Rechargeable Battery: heats and holds food with no plug, power bank or microwave required. Bottom Heating System: even heat distribution across the base so the whole portion warms through. Five Adjustable Heat Levels: from a light warm-through to full heat for a hearty dish. Up to 5 Hours Warm: holds temperature without added water once it has heated. 33.8 oz Capacity: fits rice with a curry, pasta or a stew rather than a snack portion. 60W at 7.4V: enough power to heat a full meal from cold on a single charge.
