Power adapter connector cable

This 15 cm cable links a 5.5 x 2.1 mm DC female socket to a USB-A female port so you can power or charge devices that accept USB input from a standard barrel adapter. It suits travellers and technicians who need a compact bridge between laptop chargers and USB-powered gear. The short length keeps cable clutter to a minimum on crowded desks or in bags.

Compatibility checklist

Verify that your existing power supply uses a 5.5 mm outer and 2.1 mm inner diameter barrel plug before ordering. Ensure the device you intend to power draws current within the USB-A port’s standard rating. Confirm the polarity of the source adapter matches the equipment you are connecting. No driver installation is required for basic power delivery.

Build quality and daily use

The moulded connectors incorporate overload, over-temperature and short-circuit protection to guard attached hardware during faults. Low energy consumption and smooth current transmission reduce wasted power and heat during extended sessions. Lightweight construction makes the cable easy to carry in a laptop sleeve or tool pouch without adding bulk. Plug-and-play operation means no configuration is needed each time you connect.

Questions about this item

What comes in the box with the 5.5 x 2.1mm DC female to USB AF DC female power connector cable?
