Epidemiological and Clinical Profile of Burn Injuries Linked to Mobile Device Chargers: Experience from a Specialized Burn Unit in Morocco

Abstract: Background: Burn injuries related to mobile device chargers are emerging as a concerning cause of domestic accidents, particularly in young populations with prolonged exposure to electronic devices. These injuries may result from thermal or electrical incidents linked to defective or improperly used chargers. Objectives: This study aimed to describe the epidemiological and clinical profile of patients with burn injuries caused by mobile device chargers and to highlight potential prevention strategies based on local data from a Moroccan burn unit. Methods: We conducted a retrospective, descriptive study over a 26-month period (January 2022 to February 2024) at the Plastic Surgery and Burn Unit of the University Hospital Center (CHU) of Marrakech. All patients admitted for burn injuries related to mobile device chargers were included. Demographic data, injury characteristics, management strategies, and clinical outcomes were analyzed. Results: Eight patients were included. The mean age was 27.4 years (range: 1.5–89 years), with a male predominance (sex ratio 1.66). The most common injury mechanism was thermal burn by flame (5 cases), followed by electrical flash burns (3 cases). The average burned surface area was 16.6%, with frequent involvement of the face and upper limbs. Two patients required multiple surgical interventions, and the mortality rate was 22.2%. Conclusion: Burns caused by mobile chargers represent a rare but severe domestic hazard. Public awareness, use of certified charging devices, and preventive education are essential to reduce their incidence. Further studies are needed to guide national preventive strategies in similar contexts.
