Efficiency and Functionality Eco-Friendly Wireless Charging Pad

Abstract

Nowadays, people find cellular phones as a necessity to communicate and access information, so chargers should be handy at all times to equally sustain their use. Most chargers are wired which may result to charging problems and inaccessibility when outdoors. Wired charging is a necessity then, but may not be totally available all the time. This research intended to make phone chargers even more user-friendly by eliminating physical cables and at the same time, make them eco-friendly by using solar energy as the source of electricity. The study was an experimental type of research which used a 10 -item validated questionnaire and interviews from students about the efficiency and functionality of "Eco-friendly Wireless Charging Pad". This was conducted to fifty–nine (59) students of Grade 11 and 12 EIM (Electrical Installation and Maintenance) and EPAS (Electronic Product Assembly Services) of Recto Memorial National High School through Stratified Random Sampling. The research revealed that outdoor charging problems, fire due to left plugged cell phone chargers, and octopus connections are the top concerns addressed and solved by the Eco-friendly Wireless Charging Pad. Likewise, the experiment with direct charging in cellular phones with respect to mili -Ampere hour (mAh) revealed that the higher the solar energy, the faster the time for it to be fully charged. There is a directly proportional relationship between the battery capacities (mAh), the time to be fully recharged batteries and solar energy that is consumed. With regards to the functionality as assessed by the respondents, it was found effective and useful. However improvements and adjustments on the Universal Serial Bus (USB) port of its receiver is recommended so that a longer range of distance is possible in charging the phones.
