A cold desk lunch is a small daily disappointment. This heated lunch box for adults carries its own power, so a portable food warmer for work becomes a genuinely hot meal on a building site, a train or a campsite. Most people charge it overnight and pack it in the morning, because a full charge takes about 8 hours, and a charged unit keeps a meal warm for up to 5 hours with no outlet needed.

Heating happens from the base, spreading warmth evenly through the container rather than scorching one corner. As a food heater with five adjustable heat levels, it puts the temperature in your hands. Once it reaches temperature, this warm lunch box holds food warm for up to 5 hours, and on office days, commutes and picnics this hot lunch box delivers a genuinely hot meal. The cordless heated lunch box is a self heating lunch box powered by 60W at 7.4V, and its compact white body slips into a rucksack. The base heats up in use, so keep it away from children and pets.
