Product Description - Chargers & Power Adapters

This 5V 2A Power Adapter with Cable delivers up to 10W for compatible Raspberry Pi boards, Arduino projects, speakers, controllers, development equipment, and other 5V devices. The integrated output cable provides a practical connection for installations that require a fixed power lead rather than a direct USB wall charger. OEM/ODM customization includes AC plug type, DC or USB connector, connector polarity, cable length, wire gauge, housing color, logo, labels, and packaging. Quality control can include full-load testing, output-voltage verification, cable continuity, connector fit, insulation, temperature rise, and appearance inspection. Please confirm that the selected adapter provides the voltage, current, connector, and polarity required by the target equipment.
