This Coffee Express coffee cup, designed by Joseph Cambell in collaboration with Wharton Business School, allows you to make coffee at any time during your trip. It is a rechargeable battery on the outer package of a standard kettle, which provides an electric current to heat the heating element at the bottom of the kettle. It can make two cups of coffee at a time, with a digital display of the time and temperature of brewing coffee. The price is about $30.
