ALLNET USB_DC_4.0MM_1M universele zwarte voeding en spanningsomvormer

The ALLNET USB_DC_4.0MM_1M is a universal black power supply and voltage converter that transforms a standard USB 5V input into selectable 9V or 12V DC output. Designed for devices requiring a 4.0x1.7mm DC barrel connector, this cable integrates a step-up converter and a voltage selection switch, making it ideal for powering routers, switches, cameras, and other electronics from USB power sources such as power banks, USB wall chargers, or computer ports.

Advantages

This voltage converter cable eliminates the need for multiple dedicated power adapters by allowing you to power 9V or 12V devices directly from a USB port. Its compact design and 1-meter length provide flexibility and convenience for travel, desk setups, or field use. Built-in overload and short circuit protection ensure safe operation, while the center-positive polarity matches the majority of DC-powered devices.

Suitable for

• Powering 9V or 12V devices from USB power banks, wall chargers, or computer USB ports
• Replacing bulky power adapters for routers, switches, IP cameras, and other networking equipment
• Portable electronics requiring a 4.0x1.7mm DC input jack
• DIY projects and prototyping where a regulated 9V or 12V supply is needed

Key specifications

• Input: USB Type-A Male, 5V DC
• Output: DC Barrel Jack Male, 4.0mm outer diameter, 1.7mm inner diameter
• Output Voltage: Selectable 9V DC or 12V DC via integrated switch
• Max Output Power: 10W
• Max Output Current: 1.1A at 9V, 0.83A at 12V

• Protection: Overload and short circuit protection

Recommendations

Ensure your device's DC input specifications (voltage, current, polarity, and connector size) match the output of this converter. This cable is not a charger; it requires a USB power source. For best performance, use a USB power adapter that can supply at least 2A at 5V.
