Week 7-Problem Statement

                 There are two problems that lead to this project creation and development. The first one is about charging up a battery which takes long hour to fully charge up, that is around 1 to 15 hour for small and large charge capacity rechargeable battery respectively. For small electronic devices that have embedded or replaceable rechargeable battery in it such as MP3/4, Walkman, hand phone, PDA, and I Pad, around 1 to 2 hours will be needed to fully charge it up. For large charge capacity rechargeable battery, such as power bank, around 12 to 15 hours is required to charge it up to full capacity.

                 The second problem is about lack of portable power supply that uses clean energy which is environment friendly. The diesel and petrol generator uses non-renewable natural resource that will finish “one day”. Increase in population of human kind, together with increase in their daily life necessity which requires the use of natural resource in abundant, shows that the “one day” will come very soon. Besides diesel and petrol generator, the Power Bank itself also uses non-renewable natural resource as it need to be charged using wall power supply which are mainly produced or generated using non-renewable natural resource. Only few percent out of 100% of energy generated throughout the world uses renewable energy, for example solar, wind, tidal, hydro and many more. These generators which use fuels also emit air pollutant and water pollutant that harms the environment, human being, and all the other living things. 

            One more things is that, the portable power supply available today still depend on raw material and wall power supply to operate and fully charged. Develop and implementing this project will help to reduce these problems. For problem concerning the environment, it still helps to reduce those problems as electronic products being produced in abundant and continuously, may use the portable power supply product from this project instead of using supply from wall power supply which produced from non-renewable natural resource.
