USB-to-DC power cable for 3.5 mm devices

This cable converts a standard USB-A port into a 3.5 mm outer diameter and 1.35 mm inner diameter DC plug. It suits routers, hubs, speakers or development boards that draw power from a 5 V USB source. The 1.2 m length gives flexible placement on a desk or behind equipment.

Replaces bulky wall adapters and short factory leads

Swap a dedicated mains brick for a single cable run from a laptop, power bank or multi-port charger. The upgrade is worthwhile when you want fewer outlets occupied or need to power a 3.5 mm device away from a wall socket.

Plug-and-play with no drivers required

Insert the USB-A end into any powered port and connect the barrel jack to the target device. Ensure the polarity and voltage of the USB source match the device specification; a mismatch can prevent operation or cause damage. The fixed 1.2 m length cannot be extended without an additional coupler.
