Black barrel-plug cable with 5.5 mm female jack and 3.5 mm male plug, 1.8 m long

ABLEGRID

ABLEGRID 1.8m 5.5x2.1mm to 3.5x1.0mm barrel plug cable

SKU CH-1FZ2-TK16M

A 1.8 m power cable converts a 5.5 × 2.1 mm barrel jack to a 3.5 × 1.0 mm plug for low-voltage devices

  • Connects 5.5 × 2.1 mm jack to 3.5 × 1.0 mm plug
  • 8 m length gives flexible placement for DC devices
  • New ABLEGRID cable built for reliable low-voltage power delivery
  • CE, FCC and RoHS certified for safety compliance
  • Female 5.5 mm and male 3.5 mm ends match common adapter sizes

Connector sizes

This cable bridges a 5.5mm by 2.1mm female jack to a 3.5mm by 1.0mm male plug. It lets you connect a power supply with the larger barrel to a device that accepts the smaller barrel. The 1.8m length gives reach for desk or rack setups. Rated for common low-voltage adapters including 6V, 9V, 12V and 18V units.

Suitability check

It suits anyone replacing a lost lead or extending an existing AC/DC adapter where the tip sizes match. Builders needing a different inner diameter, a right-angle plug, or a longer run should look elsewhere. The fixed 1.8m length cannot be shortened or joined without extra parts. Polarity follows the source adapter.

Deciding specification

The male tip measures 3.5mm outer diameter by 1.0mm inner diameter. Measure your device socket before ordering; a 1.3mm or 1.35mm centre pin will not make reliable contact. If the inner diameter matches, the cable completes the link.

Questions about this item

Does the 5.5 mm × 2.1 mm female jack wear out and need replacing after repeated insertions?

The barrel jack is a standard passive connector; with normal use it lasts years and only needs replacement if the centre pin loosens or the housing cracks.

What stops the 1.8 m cable from delivering full current on a 12 V or 18 V adapter under continuous load?

The limiting factor is the 3.5 mm × 1.0 mm male plug and the wire gauge, which together cap safe continuous current well below the adapter’s maximum rating.

Does the cable get warm or radiate audible noise when left plugged in all day at 9 V or 6 V?

It is a simple copper extension with no active components, so it produces no noise and only negligible warmth at the low voltages and typical currents these plugs carry.
