What this cable does
This pack contains two 15 cm power extension cords. Each cable converts a 5.5 x 2.1 mm female barrel jack into a USB Mini-B male plug. The wire has a maximum outside diameter of 3.5 mm and a nominal cross section of 0.3 mm square. It lets you power or charge USB Mini-B devices from a compatible barrel-output power adapter.
Who it suits and who it does not
It suits anyone with a spare barrel power supply who needs to run a device that takes a USB Mini-B input. It will not work for devices that require USB Micro-B, USB-C, or any other connector. Buyers who need a longer reach than 15 cm or a different barrel size should look at other options.
How it fits into a setup
The short length keeps cable clutter low on a desk or inside an enclosure. The 3.5 mm outer diameter makes routing through tight gaps straightforward. No extra drivers or configuration are needed; simply connect the barrel jack to your power source and the Mini-B plug to the target device.

Questions about this item
What size barrel power adapter must I already have to use this 5.5×2.1 mm female jack?
You need a DC power adapter with a 5.5 mm outer and 2.1 mm inner barrel plug that matches the female jack on this cable.
Will this cable work with a legacy device that charges through a USB Mini-B port?
Yes, the male Mini-B plug fits older cameras, GPS units or external drives that use the Mini-B socket for power.
How can I confirm the cable is delivering power after I connect it?
The connected USB Mini-B device should show its normal charging indicator or power-on light when the barrel adapter is live.
