Electric kettles are much more efficient than stovetop kettles. You can simply boil water faster with an electric kettle. And it's safer too, as electric kettles have an automatic shut-off if the kettle boils dry. Bodum's Bistro electric kettles feature a shielded heating element that does not contact the water, a cordless carafe that detaches from the power base for convenient pouring, and a visible water level indicator that is thoughtfully marked in cups, so it's easy to boil just as much water as you need. Bistro kettles are made of BPA-free plastic and feature push-button power and lid opening. The smaller Bistro kettles have a 17-oz. capacity, the larger holds 34 ozs.
