9V DC 1A Power Supply Adapter 5.5x2.1mm Plug, AC 100-240V to DC 9V 1A 9W Power Adapter Center Positive Wall Charger for Arduino UNO, Mega, LED Strip Lights, Router and More Devices, 1.2m Cable

Product Features

• Wide Device Compatibility with Standard Plug: Equipped with a DC 5.5mm × 2.1mm barrel connector, this 9v1a power supply adapter supports devices requiring DC 9V output under 1A (100mA–1000mA) with center positive polarity. The adapter automatically adjusts current up to 1A based on device demand. Suitable for Arduino UNO & MEGA, partial Tapo cameras (such as C100/C110/C200/C210/C212/C310 models), Crosley CR8005A Cruiser series record players, router, ADSL modems, CCTV cameras, bench scales, some 9V LED strips, and other 9V household electronics using 9V DC and center-positive 5.5 × 2.1 mm connectors. A reliable replacement for 9V 0–1A power supplies.
• Stable 9V DC Power Output for Electronics: This 9v dc power supply converts AC 100–240V input into a steady DC 9V 1A output, delivering up to 9W of reliable power. Designed to ensure consistent voltage for sensitive electronics, this power adapter helps prevent power fluctuations that may affect performance or damage devices such as Arduino boards, LED strips, and routers.
• Flame-Retardant Materials with Reliable Cable Performance: Constructed from high-quality ABS + PP flame-retardant housing, this dc 9v 1a charger power cord is designed for safe and dependable use. The high-purity copper core cable ensures stable current transmission while offering strong resistance to oxidation and corrosion. Repeated plug-in testing confirms reliable performance and long-term usability in everyday applications.
• Intelligent Chip with Multiple Safety Protections: Built with an advanced internal control chip, this switching power adapter integrates multiple protection mechanisms, including short-circuit protection, overcurrent protection, overvoltage protection, overload protection, electromagnetic interference protection, and surge protection. These safeguards help maintain stable operation and protect both the adapter and connected devices.
• Suitable for Various Projects and Applications: Ideal for DIY electronics, prototyping, home automation, and everyday equipment, this adapter supports applications such as 9v power supply for Arduino Uno, 9v adapter for Arduino Mega 2560, and 9v power supply for Tapo cameras (compatible 9V models only), ensuring stable operation across a wide range of usage scenarios.
• Important Note: Please confirm that the plug size and connector specifications match your device before purchase and use, especially the DC barrel connector interface.
