Abstract: This research work focuses on development of practical instructional guide in the production of portable Universal Serial Bus (UBS) Charger. Two research questions were set to guide the study. The study was carried out in Federal College of Education (Technical) Omoku Rivers State. The study adopted research and development design. The population for this study is 337 NCE I, II, and III electrical/electronics technology students. The sample of the study consists of 103 NCE I, II, and III which were randomly selected 34 NCE I, 42 NCE II, and 27 NCE III electrical/electronics technology students respectively. The instrument for data collection was a structured questionnaire item consisting of 33 items which adopted a five (5) point Likert scale of (VHR) very highly Required, (HR) Highly Required, (R) Required, (MR) Moderately Required, and (NR) Not required with the corresponding values of 5, 4, 3, 2, and 1 respectively. The research instrument was face validated by three lecturers in department of electrical/electronics technology in Federal College of Education (Technical) Omoku Rivers State. The reliability of the instrument was established using the Cronbach Alpha () reliability coefficient which was computed to be 0.87. Data collected from the questionnaire item was analyzed using mean. Based on the findings, it was observed that the materials and steps shown in table 1 and 2 respectively are the required ingredients in the production of portable Universal Serial Bus (UBS) charger. Therefore, it is recommended that developed portable Universal Serial Bus (USB) charger should be kept away from damped environment, hence, it may affect its functionality.
