Since most gas is consumed for boiling water, an electric kettle can greatly increase the life of the gas cylinder, reducing the need for a refill.
Most electric kettles available are of the cordless variety, where the kettle containing water is fitted on the heater plate to which the cable is connected. The kettle has an automatic cutoff which switches off when the water reaches the boiling point. Available in sizes 1 L and 1.7 L
