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

## TL;DR

This paper reports two cases of skin burns caused by mobile phone charging devices, highlighting the need for safety awareness when using such devices.

## Contribution

The study presents rare clinical cases showing that burns can occur from charging devices even without exposed electrical terminals.

## Key findings

- Skin injury can occur from brief contact with a charging phone.
- Portable power banks and electronic devices can generate heat during prolonged use.
- The cases emphasize the importance of cautious use of charging devices to prevent burns.

## Abstract

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.
