Electrical Safety and Usage Guidelines
Preferably with Built-in Batteries: Campsite power supplies are typically only for lighting, charging, and lightweight fans. High-power heating or cooling devices are strictly prohibited.
DC Priority: It is best to choose rechargeable fans with a DC power input (DC 5V/12V) to avoid power outages caused by AC power connections.
Certified: It is recommended to choose products that meet BSMI, EMI, and other certified standards to ensure safe use.; it is more suitable for personal close-range direct airflow.
