Adapter 5V 4A

The Adapter 5V 4A is a power supply that converts mains AC power into a steady 5 V DC output and can deliver up to 4 A, or 20 W. The extra current makes it a good choice for 5 V projects that need more than a phone charger or USB port can supply, such as addressable LED strips, robots with several servos, or an Arduino or ESP32 board with many modules attached.

Adapter 5V 4A Specifications

• Output voltage: 5 V DC
• Output current: up to 4 A
• Output power: up to 20 W
• Input: mains AC
• Type: AC to DC power adapter

Adapter 5V 4A Applications

• WS2812B and other 5 V addressable LED strips
• Robots and arms with several SG90 micro servos
• Arduino, ESP32 and ESP8266 projects with many modules
• Raspberry Pi projects, when the connector matches
• 5 V USB hubs, fans and small devices

What's in the Box

• 1 × 5 V 4 A power adapter

Tip: Feed high-current loads such as LED strips and servos directly from the adapter, not through the Arduino's 5 V pin, and connect all grounds together. Check the plug size and polarity before connecting, and keep the total current under 4 A.
