Solar Power Bank

Introduction
Background of the Study

The study of solar power bank has been among the top energy storage solutions in recent years, and the invented due to the erratic nature of power supply from the national grid.

A solar power bank is an energy storage device that obtains energy from the sun and uses it to charge/power various electronic gadgets, like phones, tablets, laptops, torches, bulbs, televisions, etc.

They are usually portable enough to be carried about for use when the need arises, but some are big and so need to be stationed at a spot. Solar power banks come in various capacities (usually between 1000 – 50,000 mAh) and have designs to suit individual preferences (Mehta et al., 2010).

The major feature of the solar power bank that makes it unique is that as long as there is sunlight, even just a little bit, your solar power bank will draw power. The power stored during the presence of daylight is then saved for use later. Some small solar power banks allow you to charge the power bank with both the sun or regular electricity (Mehta et al., 2010).

Most portable solar power banks can’t be used for high-power and long-hours charging. Notably, the portability of power banks is one of the reasons why people received it so well. That is understandable, because most prefer something they can carry around. This is why the large-sized solar power banks are stationed permanently or temporarily at a specified location.

Another reason why solar power bank is preferred is because is environmentally friendly. The earth is already battling so many environmental hazards and global warming is the most glaring issue today. By using solar power, you will be conserving energy, thereby reducing the strain on mother earth.This is because solar energy is pollution-free; it is clean, renewable energy. Its use doesn’t promote the emission of greenhouse gases, unlike regular electricity; instead, you are only tapping sunlight.

As a standby power, getting a solar power bank will help you stay connected most especially when there is no electricity.

Problem Statement
Dealing with an empty phone in the middle of a long trip or browsing for some information that is very important can be a frustrating experience, especially if you have an urgent phone call to take at the moment. In other to avoid being in this kind of situation, the use of solar power banks for your mobile phones is the solution.

Primarily, solar power banks refer to portable battery packs that collect power from the sunlight and turn it into electricity. This electricity can be used for charging mobile phones and other electronic devices without plugging them into an electrical socket.

Justification of the Study
The biggest advantages of using solar power bank is that one will be able to charge thier electronic devices without being near a power outlet. That is, if someone needs to charge his or phone, for example, you will be able to do so. Solar power bank small size makes them easily movable, they are very easy to use and you can charge them by plugging them into an outlet or with solar energy.

Aims and Objective
The main aim of this seminar is to carry out a study on a solar power bank. The objectives of the study are:

• To carry out a review on a solar power bank
• To study the advantages of using a solar power bank
• To study the constructional view of a solar power bank

Scope and Limitation of the Study
The scope of this seminar covers the study solar power bank which is which is a device that have batteries that can be charged with solar energy and allow you to recharge without having to connect appliances to an outlet, and can charge plugging them into a power outlet as well as with solar energy. They are normal power banks with solar panels.
