Power cable for 5 V DC devices

This USB Type-A to DC 5.5 × 2.1 mm cable delivers 5 V power at up to 3 A. An integrated on-off switch lets you cut power without unplugging the connector. It is intended for low-power peripherals such as desk lamps, small fans or LED strips. The cable carries no data signals.

Fits standard USB-A ports and 5.5 mm DC jacks

Plug the USB-A end into any 5 V USB charger, power bank or PC port and the barrel plug into a matching device jack. The 100 cm length gives placement freedom while the switch saves wear on the DC socket. No fast-charge protocols are supported so high-draw hardware will not operate.

Passive design runs cool and silent

With no active electronics the cable produces no heat or noise beyond the attached device. Current is limited to the USB source and the 3 A cable rating. It cannot be used with Power Delivery chargers or for data transfer.
