Short 11 cm black cable with a 4.0x1.7 mm barrel jack and Mini USB plug

Unique-Bargains 11cm DC 4.0x1.7mm Female to Mini USB Male Cable

SKU CH-SSK4-DGSWC

An 11 cm cable converts a 4.0×1.7 mm barrel power output to a Mini-USB plug for charging USB devices

  • Product typePower
  • Short 11 cm cable keeps installations tidy
  • 0×1.7 mm barrel jack fits many DC power adapters
  • Mini USB male plug powers USB devices from barrel source
  • 5 mm outer diameter wire handles typical low-voltage loads
  • 3 mm² conductors deliver reliable current for small electronics

Connector Pairing

This cable joins a 4.0x1.7mm female barrel jack to a USB Mini-B male plug. It lets a DC power adapter with a matching barrel connector supply power to a device that accepts a Mini-USB input. The assembly is new and measures 11cm including both connectors.

Cable Construction

The wire has a maximum outside diameter of 3.5mm and a nominal cross section of 0.3 mm square. At 4.33 inches long, the short lead keeps voltage drop low and reduces clutter in tight installations. The male-to-female orientation simplifies routing for cameras and similar equipment.

Intended Use Cases

Suitable for installers who need to power Mini-USB devices from an existing barrel-output supply. Not for users whose equipment requires a different barrel size, a Micro-USB or USB-C connector, or a longer cable run. Buyers who need data transfer should look elsewhere, as this cable carries power only.

Questions about this item

Will the 4.0x1.7mm barrel jack wear out from repeated plugging and unplugging?

The barrel jack is a passive connector rated for typical insertion cycles; avoid excessive force when mating the 4.0mm outer and 1.7mm inner contacts.

What limits continuous power delivery through the 0.3 mm² conductors?

The 0.3 mm² nominal cross-section and 3.5 mm cable diameter restrict sustained current; expect voltage drop on loads above a few watts.

Does the 11 cm cable get warm when powering a device all day?

With 0.3 mm² conductors the wire will warm slightly under continuous load; keep the 11 cm run in open air to dissipate heat.
