Air DC Fan With Voice Control, Speaker Floor Fan Fan-01 Power Adapter and Battery Selection

Power Adapter
Rated Power and Voltage:
Calculate Power Requirements: Select an adapter based on the power requirements of the device. For example, if the device power is 25W, it is recommended to select an adapter with a rated power of 30W to prevent damage to the adapter due to excessive instantaneous current.
Voltage Matching: The output voltage of the adapter must match the device requirements. Too high or too low may cause damage to the device or malfunction.
Safety Certification:
International Certification: Make sure the adapter has certifications such as UL (USA), CE (Europe), FCC (Federal Communications Commission). These certifications mean that the adapter has been rigorously tested and meets safety and performance standards.
Overload and Short Circuit Protection:
Design Protection Circuit: Overload protection is usually achieved through a fuse or current limiting circuit, which automatically cuts off the power when the current exceeds the set value.
Short Circuit Protection: In the event of a short circuit, the adapter should be able to quickly disconnect the power supply to avoid fire or equipment damage.
Heat dissipation design:
Heat dissipation materials and structures: Aluminum alloy shell or ventilation hole design is used to enhance heat dissipation efficiency and ensure that the temperature of the adapter remains within a safe range when working under high load.
Plug compatibility:
Multiple plug options: Plug versions for different countries or regions are provided, or a replaceable plug design is used to improve the applicability of the adapter.

Battery selection
Type selection:
Lithium-ion battery: It has high energy density (for example, 250-300Wh/kg), and is small in size and light in weight, suitable for portable devices.
Lithium polymer battery: Thinner and easy to design into various shapes, suitable for devices that need to save space.
Battery management system (BMS):
Charging management: BMS can monitor the voltage of each single cell to ensure a balanced charging process and avoid overcharging.
Discharge protection: When the battery power is lower than the set value, the BMS can automatically cut off the power supply to prevent battery damage caused by over-discharge.
Temperature protection:
Integrated temperature sensor: Real-time monitoring of battery temperature, automatically reducing frequency or shutting down charging and discharging when the set temperature is exceeded.
Environmental protection and recycling:
Material selection: Prioritize environmentally friendly materials such as cadmium-free and lead-free to reduce environmental pollution.
Recycling program: Provide users with recycling channels to promote sustainable development.
Compatibility:
Interface and circuit design: Ensure that the battery interface is compatible with the device circuit and use standardized interface design (such as XT60, JST, etc.) to facilitate connection and replacement.
