USB 5 V to 9 V/12 V boost cable

This SMUGDESK cable integrates a boost converter that raises a standard USB 5 V supply to a stable 9 V or 12 V DC output. It terminates in a 5.5×2.1 mm DC male plug and draws power from any USB charger, power bank or laptop port.

Devices needing 9 V or 12 V from USB

The cable suits routers, mini cameras, LED strips, portable audio gear and single-board computers that require 9 V or 12 V and accept the 5.5×2.1 mm barrel connector. It will not work for equipment needing a different voltage, higher current than the USB source can deliver, or a different DC plug size.

Plug-and-play installation

Simply connect the USB end to a 5 V source and the DC plug to the target device; no drivers or configuration are required. The most common issue is insufficient current from the USB port, which can cause voltage drop or device instability under load.

Questions about this item

What USB power source do I need to run this 5.5x2.1mm DC boost cable?

Plug the USB end into any 5V source such as a USB charger, power bank or laptop port to get 9V or 12V DC output.

Will the 5.5x2.1mm plug fit the DC jack on my older router that needs 9V or 12V?

The 5.5x2.1mm male plug matches the standard barrel size used on most routers, cameras and similar low-power DC gear.

How can I confirm the cable is delivering a stable 9V or 12V after I connect it?

Measure the DC plug with a multimeter; a steady reading at the chosen voltage with low ripple shows the boost chip is working correctly.
