  • Converts 5V USB power to 9V or 12V DC for low-voltage devices
  • Standard 5.5mm x 2.1mm barrel plug fits most small electronics
  • Built-in boost circuit with overvoltage, overcurrent and short-circuit protection
  • Compact cable design simplifies wiring and saves space in DIY projects
  • Powers routers, LED strips, fans, cameras and other mini electronics

Input and Output Voltage

This compact boost converter cable accepts a standard 5 V USB power source and steps the output up to either 9 V or 12 V DC. It is built for DIY enthusiasts, hobbyists and technicians who need to run low-voltage gear from common USB power banks, wall adapters or computer ports. The integrated 5.5 mm by 2.1 mm barrel plug fits the majority of small DC-powered devices.

Suitable Devices and Limitations

The cable suits wireless routers, LED strips, mini cooling fans, small surveillance cameras, portable audio players and single-board microcontrollers that require 9 V or 12 V input. Equipment that demands a different voltage, a higher current than the module can deliver, or a connector other than the 5.5 × 2.1 mm barrel will need an alternative power solution.

Connector Specification

The only physical interface is a 5.5 mm outer by 2.1 mm inner DC male barrel connector on the output side. Match this exact plug size to the device’s power jack before purchase; any other jack diameter or pin configuration will not connect.

Questions about this item

Which output voltage should I select, 9 V or 12 V?

Choose the voltage that matches the rating printed on your device; the cable can deliver either 9 V or 12 V from a 5 V USB source.

What does the 12 V output mean when I plug this into a router?

It provides a regulated 12 V supply so the router runs normally from a standard 5 V USB power bank or adapter.

How does the 5.5 mm by 2.1 mm barrel connector limit what I can power?

Only devices that accept a 5.5 mm outer and 2.1 mm inner DC plug can be connected; other barrel sizes will not fit.
