Abstract
With the advances of technology and growing demand of sustainable energy and to address the needs of devices that can work during emergency because Philippines always suffer from natural catastrophe as well as for survivability during crisis, long travels, camping and search and rescue missions. This study constructed a multi-function survival off grid power generating device abbreviated as MSOGPGD. Using nominal test loads to test and measure every feature and specification of function, and parameter as well as its functionality, reliability, maintainability, usability, and performance. This developmental research employed two different activities such as direct observation and evaluation to target users: five (5) of them were DRRM practitioners, 15 electrical engineers/professors/instructors and 40 target users were chosen randomly. The motor generator delivers enough voltage to power up small electrical appliances such as lightings, radio, and cellphone chargers. The motor generator has a maximum of 50-60 watts output generation which already enough power to power up necessary gadget and appliances during emergency situations. The regulated DC output was stable enough to power up to maximum of 75 watts. The battery connected variable DC supply was operational from 1.2 volts up to 32 volts. The battery rating was 15,000mAH and can charge cellphone two times before it runs out of power with additional feature of flashlight and lighter/igniter functions properly and readily available. MSOGPGD gains a positive response from the randomly selected target users in which MSOGPGD was “Very Acceptable” in terms of design, composition, safety, and operating performance. Although the built-in generator generates less power than expected it still performs the operations which it intended to during emergency situations as DRRM personnels reiterated and very useful in life and death situations. It was also suggested that if it is mass produced it will help people during calamities and search and rescue operations and help to survive in harsh situations.
