USB to 2.1mm DC Booster Cable - 9V

This cable features an integrated boost converter allowing you to power 9V devices from any USB port, such as a computer or battery pack. It outputs a higher DC voltage with a center-positive 2.1mm DC barrel jack, providing a convenient power solution.

Key Features:

• Boost converter integrated to increase voltage from USB 5V to 9V DC output
• Compatible with any USB port
• Output rated at 500mA maximum current
• Center-positive 2.1mm DC barrel plug suitable for various devices
• Approximately 1.2 meters (47 inches) cable length for flexible use
• Lightweight design weighing 35.1 grams

Performance and Efficiency:

• 90% efficiency at low current draw (50mA)
• Efficiency decreases to around 80% at high current draw (500mA)
• Quiescent current around 3mA
• USB port voltage drop and cable quality may affect overall output voltage and performance
