USB A to DC 3.5 mm - 1.35 mm 5 Volt DC Barrel Jack Power Cable

‌The USB A to DC 3.5 mm - 1.35 mm 5 Volt DC Barrel Jack Power Cable is a versatile power cable designed to deliver 5V DC power from a standard USB port to devices that use a 3.5 mm outer diameter and 1.35 mm inner diameter barrel jack for power input. This cable is commonly used for powering small electronic devices, such as routers, LED lights, portable speakers, and other low-power peripherals, directly from a USB power source.

Technical Specifications:

Connector A (USB Type-A Male):

Type: Standard USB Type-A male connector.

Interface: USB 2.0/3.0 compatible, typically drawing power from a USB port on a computer, power bank, or USB wall adapter.

Power Output: Delivers 5V DC with a current output depending on the USB source, usually up to 500mA for USB 2.0 and up to 900mA or more for USB 3.0 and higher.

Connector B (DC Barrel Jack, 3.5 mm x 1.35 mm):

Type: DC barrel jack with a 3.5 mm outer diameter and 1.35 mm inner diameter.

Polarity: Typically configured with a positive inner pin and a negative outer sleeve, which is standard for most small electronic devices.

Voltage: Specifically designed to provide 5V DC, corresponding to the output voltage from the USB power source.

Cable Length:

Typically ranges from 0.5 meters to 1.5 meters, offering flexibility in device placement relative to the USB power source.

Cable Construction:

Material: The cable is usually made of high-quality copper conductors for efficient power delivery with minimal voltage drop.

Insulation: Covered with a durable PVC jacket that provides insulation and protection against wear and tear.

Use Case:

The USB A to DC 3.5 mm - 1.35 mm power cable is ideal for powering small electronic devices that require 5V DC input, especially in situations where traditional power adapters are impractical or unavailable. This cable is widely used to power devices like Wi-Fi routers, LED strips, portable fans, and other peripherals directly from a USB port, making it a convenient solution for mobile setups, DIY projects, and scenarios where power outlets are scarce.
