Clinical and Pathological Features of Cutaneous Burns Caused by Mobile Phone Charging Devices

We report two rare cases of cutaneous burns associated with portable charging devices: one from a micro-USB cable and the other from a power bank. Notably, even without exposed electrical terminals, skin injury can occur with brief contact with a charging phone. Portable power banks and other electronic devices may generate heat during prolonged use. These cases underscore the need for safety awareness regarding charging devices and caution against careless use while connected to a power supply, particularly during sleep or in situations with limited ability to respond to hazards.
