Solar Power Bank comprises of a Solar Photovoltaic Modules, Solar Power Conditioning Unit (special circuit to control power flow), battery Bank. They allow one to store electrical energy (deposit it in the bank by Solar Photovoltaic cell). Solar Photovoltaic cell which produces electricity only from solar panels and meets the load requirement and then later use it to charge up a mobile device.

CHAPTER ONE
1.0                                                         INTRODUCTION
Sometimes there is nothing worse than losing all the charges on your Smartphone especially when you are in the middle of something very important. Usually this happens at the most inconvenient time probably when you are using your phone to surf the web, in the middle of a phone call or when you are desperate to send an important email or text message. Nonetheless, in this dispensation of global village, there is never a good time!  If you are always on the move, the very last thing you would imagine is to have your Smartphone low or even empty on battery. For those who depend largely on their mobile devices, not having enough power for the battery can be a major catastrophe. How else will people reach you or how will you contact people for business or personal reasons when your phone is basically useless as it has gone off on you? All these are problem to our present time, to bring this problem to an end, powerbank was introduced which is a portable device that can supply USB power using stored energy in its built-in batteries. Powerbanks usually recharge with USB power.

1.2                                             OBJECTIVE OF THE PROJECT
The objective of the project is to design a solar dependable device that is used to recharge small devices such as cellphone when and where there is no charge to charge the device. A connector is added to complete the design. The type of connector will depend on the device to be charged. Cell phones require the Micro-USB “type B” receptacle connector.
1.3                                         SIGNIFICANCE OF THE PROJECT
Solar Power bank serve as an ‘extra battery’ or external charger for your phone or other electronic devices. Solar Power bank helps to ensure longer hours of texting, phone calls, or web browsing using your mobile phone.

1.4                                                 SCOPE OF THE PROJECT
Cell-phone batteries often die at very inconvenient times, with no ac power outlet nearby. This device uses  standard AA batteries, which can be bought almost anywhere, to recharge cell phones and other portable devices like music players, e-book readers, and cameras.
The circuit chargers that typically come with cell phones and other portable devices charge the battery for a brief period of time. Then, they stop, check the voltage, and verify the temperature against an internal table before deciding to stop or continue the charging process. The charging regulation required by the battery is performed within the device getting charged, and this design takes advantage of that circuit.

1.5                                           LIMITATION OF THE PROJECT

• It can only be recharged with solar energy through solar panel
• The duration of the charged when in used depend on the number of cell used.
• Using solar energy for this device means that charging the power bank during cloudy or raining time becomes a problem.

1.6                          PROJECT WORK ORGANISATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
Chapter one of this work is on the introduction to the study. In this chapter, the background, significance, objective, limitation and scope of the study were discussed.
Chapter two is on literature review of this study. In this chapter, all the literature pertaining to this work was reviewed.
Chapter three is on design methodology. In this chapter all the method involved during the design and construction were discussed.
Chapter four is on testing analysis. All testing that result accurate functionality was analyzed.
Chapter five is on conclusion, recommendation and references.
