If you encounter an unfamiliar plug-in device, look carefully—without opening or dismantling it—for:
- A brand name or model number
- Safety or certification markings
- A visible LED or light source
- A switch, sensor, or control button
- Printed instructions or symbols
- A USB port or other connection
- Any unusual smell, heat, buzzing, or discoloration
These clues can often reveal what the device is intended to do.
