Our project studies the development of a phone case charged by solar energy. As long as the customers are in an area with direct sunlight/light, the case will automatically charge their phones. This portable product will help customers prolong their battery life while being outdoors and having no outlet. This product will directly compete with products like a portable charger or a built-in battery phone case. Even though the battery it brings might not be as strong as the competitors, its size, weight and the convenience it brings will make up for it. Our study will focus on how much battery this solar case charges, how budget-friendly it is, and how its design can be portable for our user base.


In recent years, the development of technology brings about many new features and utilities for mobile devices, especially phones. However, these new developments come with a disadvantage–they use up phone batteries fairly quickly. Nowadays, it is rare for phone batteries to last for a day, as more and more features are added and people can use phones for pretty much everything. This calls for a demand for portable chargers, since we are not always indoors to get a power outlet to charge our phones. We aim to look into the viability of a product that satisfies requirements of a normal portable charger but is more compact so it is more convenient to carry around, with an advantage of using solar energy so electricity would not be necessary.

Survey Design

For our survey, we included two eligibility requirements: participants had to be over 18 years old and spend a lot of time outdoors. For the first requirement, we set an age limit to make sure that participants are able to provide consent when needed. Secondly, since our study is about a wireless solar charging case, we aim to focus on individuals who are frequently outside, engaged in outdoor activities, and get exposed to a lot of sunlight. By setting this eligibility requirement, we want to understand the potential demand for our product among people who are likely to benefit from its functionality.

We collected information about our respondents’ age, location, gender and household income. By collecting information on these data, we hope to gain insights into the preferences, behaviors, geographical traits, and financial capacity of our target audience. This information will later on help us with developing a well-rounded product, marketing, and decision-making processes.

We provided the respondents with a product sample and diagram detailing how our product would look like, what its weight, price, power output, capacity, and technology type would be, along with their respective units. Using this image of the solar case design, we hope respondents could get a contextual and visual understanding of the product and utilize it in their decision-making process while taking the survey.
