Circumferential Partial-Thickness Burn Caused by Mobile Telephone Charger: A Case Report

Many children and adolescents have access to portable electronic devices. Although not always the case, these devices are often charged at nighttime, especially while being used in bed. There are increasing media reports of electric current injury from the portable electronic devices' charging cables, particularly with equipment that is available for lower cost from generic manufacturers. A 19-year-old woman presented to the pediatric emergency department after a burn from her generic iPhone charger. She was lying in bed wearing a chain necklace, with the charger underneath her pillow and plugged into an electrical outlet, when she felt a sudden burning sensation and severe pain around her neck. She was found to have a circumferential partial-thickness burn. She underwent computed tomographic angiogram, whose result was unremarkable. The wound was debrided, and she was then discharged home. She likely sustained an electrical injury from the charger as it came in contact with her necklace, causing a burn. Several companies have investigated the difference in quality and safety of generic versus Apple-brand chargers and have found that the majority of the generic chargers fail basic safety testing, making them a higher risk for electrical injury. As a result of this case, patients and families should be educated about safe use of these devices, especially while they are charging.
