Abstract: Portable power banks are comprised of battery in a case with a circuit to control power flow. Power banks are becoming increasingly popular because the battery life of phones, tablets and portable media players is ex ceeded by the number of time gadgets used in aday. In this paper, the design and implementation of power bank using supercapacitors as a charge storage device is presented. Existing power banks use batteries to store charges and it takes a long time to charge completely. In this work, batteries are replaced with supercapacitors to take advantage of its quick charging and slow discharging feature. Supercapacitors are charged using charging and regulation circuit. An output regulator circuit delivers the necessary power for charging portable devices. A display is also implemented using a PIC microcontroller for monitoring.
Keywords: Supercapacitor, Input regulator, Output regulator, Charging circuit.
