PEDAL POWER PHONE CHARGER WITH A POWER BANK1PRESENTATION OUTLINEINTRODUCTIONLITERATURE REVIEWDESIGN AND SPECIFICTIONRESULTS AND ANALYSISRECOMMENDATION AND CONCLUSION
EXCELLENCE IN TECHNOLOGY EDUCATION2INTRODUCTIONCell phones are communication devices which are seen almost everywhere these days.A pedal power phone charger is a system that converts mechanical motion into electrical motion or currents to drive (charge) mobile devices (phones, iPads, tablets, etc.)
EXCELLENCE IN TECHNOLOGY EDUCATION3Mobile phones and other smart devices need a constant supply of energy in other to work accuratelyWith the current unreliable power situation, it becomes a problem since these devices require a constant supply of power
EXCELLENCE IN TECHNOLOGY EDUCATION4PROBLEM STATEMENT4OBJECTIVES OF THE STUDYTo design, simulate and construct a pedal power phone charger with a power bank.
EXCELLENCE IN TECHNOLOGY EDUCATION5SIGNIFICANCE OF THE STUDYThe system will have a power bank to store energy for later useThe system will be very affordable to middle and low income earners

RECOMMENDATION AND CONCLUSION
It is recommended that mobile phone accessory manufacturers take up and improve on this project for commercial production.On completion of the project the packaging was not very presentable its recommended that with time a better package will be produced.EXCELLENCE IN TECHNOLOGY EDUCATION17CONCLUSIONThe objectives I set out to achieve was; to design, simulate, test and construct a pedal power phone charger with a power bank and these have been met. The device was able to charge some smart phones and GSM phones
RECOMMENDATIONFurther works should be done THANK YOUEXCELLENCE IN TECHNOLOGY EDUCATION20
