Power adapter for 12 V devices

This SMUGDESK cable converts a standard USB 5 V source into a stable 12 V DC output using an integrated step-up module. It targets users who need to run low-power 12 V equipment such as routers, LED strips or small cameras from a USB charger, power bank or laptop port. The plug-and-play design requires no drivers or configuration.

5.5 × 2.1 mm barrel connector

The single specification that determines compatibility is the 5.5 mm by 2.1 mm DC barrel male plug, the most common size for 12 V peripherals. Your device must use exactly this connector and operate at 12 V; the cable cannot supply other voltages or fit different barrel dimensions. Confirm the device power draw before connecting.

Simple plug-and-play installation

Plug the USB-A end into any 5 V USB power source and insert the barrel plug into the device. The built-in protection circuit guards against overcurrent, overvoltage and short circuits. The one-metre length allows flexible routing. Problems usually arise when the device demands more current than the USB source can deliver or when the device voltage is not 12 V.

Questions about this item

What does the 12 V output mean for my device?

The built-in step-up module raises the 5 V USB supply to a steady 12 V DC so compatible routers, cameras, LED strips or fans receive the voltage they require.

Which USB interface does the cable use and what current limit applies?

A standard USB-A plug draws power from any USB charger, power bank or laptop port; the converter delivers up to the source’s rated current at 12 V.

What connector size fits the barrel jack on this cable?

The male plug measures 5.5 mm outer diameter by 2.1 mm inner diameter, matching the common DC barrel socket on many small 12 V gadgets.
