The study is focused mainly on the development of a multi-purpose solar charger. The experimental method focused on project development was used in this study. The findings of the study are : A Solar Powerbank Multipurpose Charger could be designed and constructed using locally available supplies and materials. The steps involved are; planning, designing, assembling ,testing and revising. The defects found are as follows; the 5 x 2 watt resistor is getting hot during charging process, the circuit capacity is limited for 3 loads only to be charged simultaneously, the charger's capacity increased from 3-5 mobile phones but 7808 IC produced high temperature, the charger refuse to charge some models of mobile phone due to specified ampere capacity of some models, especially in low ampere and the occurrence of unusual heat from the 7808 IC in short period of operation. Finally, the devise was highly acceptable in terms of; design, construction, functionality and safety.
