Adaptor 5v 2A

Overview

The 5V 2A DC Power Supply Adapter (5.5mm × 2.1mm Jack) is a regulated switching power adapter engineered to deliver clean, quiet, and continuous 5V DC electricity to sensitive electronics, microcontrollers, single-board computers, and network peripherals. Designed with universal 100V–240V AC input compatibility and terminating in an industry-standard 5.5mm × 2.1mm center-positive barrel connector, it outputs a stable 10W of continuous power with minimal ripple voltage. Built-in electronic safeguards against short circuits, over-current, and thermal overload ensure that your valuable dev boards remain fully protected against grid fluctuations.

Key Features

• Stable Regulated 5V DC Output: Advanced switching circuitry maintains precise 5.0V output under varying load demands, preventing brownouts and MCU resets.
• Continuous 2A (2000mA) Capacity: Delivers plenty of headroom for driving microcontrollers alongside multiple relay boards, servos, sensors, and displays.
• Standard 5.5mm × 2.1mm Barrel Jack: Directly plugs into Arduino development boards, expansion shields, routers, and CCTV accessories.
• Universal Mains Input (100V–240V AC): Operates reliably across fluctuating mains voltages without overheating or dropping output voltage.
• Comprehensive Protection Features: Integrated automatic short-circuit cutoff, over-voltage clamp, and thermal protection safeguard your projects.
• Compact Wall-Wart Form Factor: Slim footprint leaves adjacent wall and power strip sockets unobstructed.

MOKWN Recommendation

Powering multiple relays, servos, or an ESP32 Wi-Fi board directly from your computer's USB port often leads to brownout resets or blown motherboard ports. Using an external 5V 2A adapter gives your circuit dedicated, clean power while keeping your computer safe. The 5.5x2.1mm plug is the universal standard in maker electronics.
