If your office doesn't have a microwave, now a Willcook "microwave" shoulder bag, that only weighs 160 grams, could help to heat your food. Different from a cordless microwave, which runs on power tool batteries, the Willcook delivers a hot meal without needing access to kitchen appliances or a roaring fire.

Although described as a "microwave" bag, the bag doesn't actually use the same technology as microwave ovens. Instead, it is made from woven fabric powered by an external battery. The fabric looks and feels no different to regular fabrics and can even be cut, sewn and washed without affecting its functionality.

The bag includes a rechargeable battery, which fits into a small external pocket attached to the bag and provides the power to heat the meal or beverage.

The interior of the bag can reach a temperature of 80 degrees Celsius in just five minutes, and the battery life depends on the temperature to be maintained inside the bag.

There are no controls on the bag as turning it on and off and making temperature adjustments is done through a mobile app. The user can also use the app to check the remaining battery life while the bag is heating.
