An electric bed includes a bed frame, a power converter mounted with the bed frame for converting a 110V AC power to a 5V DC power, and a USB receptacle mounted to the bed frame and electrically connected with the power converter for transmitting the 5V DC power generated by the power converter. By this way, a user lying down on the electric bed can charge an electric device through the USB receptacle without leaving the electric bed, thereby enhancing the convenience of the user.
