Package Includes:

• 1 × USB to 9V DC Power Cable

Compatibility Notes:

• Use with USB power sources that can supply at least 2A for stable 9V 1A output.
• Ensure your device uses a 5.5mm x 2.1mm barrel connector and accepts 9V DC input.
• Not suitable for devices requiring more than 9W power.

Important Notes:

• Not suitable for high-power 9V devices like larger routers or guitar pedals unless they draw low current (<1A).
• Ensure your USB power source can supply enough current — typical USB 2.0 ports max out at 500mA, USB 3.0 at 900mA, and USB chargers/power banks vary (some go up to 2A or more).
• Always check the polarity and voltage requirements of your device before use to avoid damage.
