The Design of 25,200 mAh Solar-based Portable Powerbank with Dual Output as Alternate Power Source

Abstract

This paper describes about how to design and build a portable powerbank with 25,200 mAh capacity which can be charged using mini solar panel PV. In this study, the power output by the powerbank will be measured and tested on several load devices like smartphones and tablet. The test result shows that this powerbank is capable to receive input voltage from the solar panel with average 10V, and also able to produce output power with average value of 1100 mAh to the load devices.
