Here are some measures you should consider when using a public charging station:

1. Check the charging station for any visible damage before plugging in your device.
2. Avoid using charging stations that do not display an authentication or verification process.
3. Avoid leaving your device unattended while charging.
4. Wait until the device is completely charged before unplugging.
5. Check for any unknown devices or cables connected to the charging station.
6. Disconnect the device and unplug the power cord from the charging station once it is fully charged.
