Power switch cable for DC devices

This 100cm cable connects a USB-A power source to hardware with a 5.5x2.1mm DC jack. An inline button lets you cut power without unplugging, which reduces wear on the DC port. The cable carries only power and does not transmit data.

Capacity limited to 5V 3A maximum

It comfortably runs low-power gear such as LED lamps, small USB fans or a tachograph. The two-core design cannot support high-current devices such as laptops and will not work with PD chargers or any fast-charging protocol.

Passive wiring runs cool and silent

With no active electronics the cable produces no heat or noise in normal use. Power draw matches the attached load up to the 3A ceiling, and the simple switch adds no measurable loss.

Questions about this item

Will the 5.5x2.1 mm plug fit the DC port on my older LED desk lamp?

The cable uses a 5.5 mm outer and 2.1 mm inner diameter barrel plug, which matches the common DC jack on many small lamps and fans.

How can I confirm the switch is actually cutting power to my USB fan?

Press the inline button; the fan should stop immediately when the switch is off and restart when pressed again, showing the power path is being opened and closed.

Does the package include a USB power adapter or only the switch cable itself?

Only the 100 cm switch cable is supplied; a standard USB-A power source such as a charger or power bank must be provided separately.
