USB-A to DC Jack Male Power Adapter Cable – 1 Meter

The USB-A to DC Jack Male Power Adapter Cable converts the USB-A port on a power bank, laptop, wall charger, or USB hub into a 5V DC barrel jack power output. Many electronics devices – Arduino boards, routers, LED strips, and chargers — accept power through a DC barrel jack rather than a USB port. This cable bridges the two connector formats: USB-A on one end draws 5V from the USB source, and the DC jack male on the other end plugs directly into the device’s barrel jack power input socket.

The usb to dc power cable rated at 2A maximum means the USB source must be capable of providing at least 2A output at 5V for devices pulling the full rated load. Standard USB-A 2.0 ports on laptops supply 500mA only — suitable for light loads. USB-A 3.0 ports provide up to 900mA, and dedicated USB charger ports or USB wall adapters typically provide 1A to 2.4A. Matching the USB source output current to the actual device requirement determines whether this cable can power a given device reliably from that source.

The dc jack male power cable 1 metre length reaches from a desk-mounted USB charger or power strip to a device sitting at standard workbench distance. The barrel jack connector size on the DC end must match the device’s barrel dc jack input socket — the most common size/approx size is 5.5mm outer diameter with 2.1mm inner pin. Confirm the barrel jack size against the target device specification. This dc power cable available on StemVolt, for use on usb-powered 5V electronics projects and build power adapter projects.
