USB 3.0 to 12V DC step-up cable

This cable converts a USB 3.0 port’s 5 V supply into a regulated 12 V output through a 5.5×2.1 mm barrel plug. It delivers up to 1.5 A and 18 W, making it suitable for powering routers, LED strips or similar 12 V devices from a compatible power bank or charger. The 100 cm black cable uses a standard USB 2.0 Type-A input connector.

Ideal for backup router power and portable 12V gear

Users who need a compact way to run a 12 V Wi-Fi router, light cat or small switch from a USB 3.0 power bank during outages will find this cable fit for purpose. It is not intended for devices that draw more than 18 W or require a different barrel size, nor for setups where only USB 2.0 ports are available.

5.5×2.1 mm centre-positive barrel output

The single deciding specification is the 5.5 mm outer / 2.1 mm inner diameter plug with centre-positive polarity; only equipment matching this exact connector and the 12 V / 1.5 A limit can be powered safely.

Questions about this item

What USB port on my power bank or charger is required for the cable to output 12V?

The cable needs a USB 3.0 port to deliver 12V; a standard USB 2.0 port will only provide 5V output.

Will this cable power my existing 12V router that draws less than 18W?

Yes, it supplies up to 1.5A at 12V for devices under 18W such as routers, switches or LED strips.

How can I confirm the cable is boosting voltage correctly after I plug it in?

With a USB 3.0 source connected, measure the 5.5×2.1mm plug — it should read 12V; a USB 2.0 source will show only 5V.
