Power receptacles are electrical connectors that provide standardized interfaces for plugging in devices to access AC power in smart home outlets with USB charging capabilities.
Power receptacles are electromechanical components designed to safely deliver alternating current (AC) electrical power from building wiring to connected devices through standardized plug interfaces. In smart home electrical outlets with USB charging, these receptacles integrate with USB power delivery circuits while maintaining isolation between AC and DC systems. They feature contact mechanisms, insulation barriers, and mounting structures that comply with regional electrical standards for voltage (typically 100-240V AC), current (10-20A), and safety requirements.

这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
A power receptacle delivers AC power (typically 100-240V) through standardized plug interfaces for general appliances, while USB ports provide DC power (5V) for charging small electronics like phones and tablets. In smart outlets, they are integrated but electrically isolated systems.
They incorporate features such as shutters to prevent accidental contact with live parts, grounding terminals for fault protection, flame-retardant insulation materials, and compliance with standards like UL 498 and IEC 60884 for electrical and fire safety.
Standard receptacles in smart outlets are rated for 15A/125V or similar; high-power devices may require dedicated circuits or higher-rated receptacles. Always check the device's power requirements and receptacle specifications to avoid overload.
