Based in South Australia, KEY is known for its commitment to quality manufacturing, rigorous quality standards, and reliable products designed for demanding automotive, electrical, industrial, and resource sector applications. KEY continues to support Australian industry with a strong focus on performance, durability, and dependable engineering.

Superior Conductivity with OFHC Copper Construction

Unlike conventional automotive cables, this 26mm² single core automotive cable utilises high-purity OFHC copper to maximise current flow and minimise resistance. The reduced impurity content helps lower heat generation under load, improving overall system efficiency and reducing energy losses. Whether powering a dual battery setup, feeding a DC-DC charger, or supplying current to a high-capacity inverter, this cable helps maintain stable voltage delivery throughout the system.

OFHC copper also offers enhanced resistance to hydrogen embrittlement and mechanical fatigue. This makes it particularly suitable for installations exposed to constant vibration, temperature fluctuations, and harsh environmental conditions commonly encountered in 4WDs, caravans, commercial vehicles, marine vessels, and industrial equipment.

Designed for High-Current 12V, 24V & 48V Systems

The substantial 26mm² conductor size, commonly referred to as 3B&S automotive cable, is ideal for applications requiring dependable high-current performance over longer cable runs. Rated for a maximum DC voltage of 120V, it is perfectly suited for modern vehicle electrical systems, lithium battery installations, inverter circuits, auxiliary battery banks, and renewable energy systems. The cable's low-resistance construction helps minimise voltage drop, making it an excellent choice for demanding power distribution applications.

Common Applications Include:

  • Dual battery systems in 4WDs, caravans and camper trailers
  • Battery interconnects and auxiliary battery wiring
  • DC-DC charger installations and lithium battery systems
  • High-current inverter and solar power systems
  • Marine electrical systems and battery banks
  • Commercial vehicle, fleet and industrial power distribution

Built to Australian Standards for Long-Term Reliability

Manufactured to comply with AS/NZS 1125 conductor requirements and AS/NZS 3808:2000 insulation standards, this cable delivers dependable performance in demanding environments. The durable V90 insulation provides excellent resistance to heat, abrasion, oils, fuels, and common automotive chemicals while maintaining flexibility for easier installation through chassis rails, conduits, and tight engine bay spaces.

The black outer sheath allows clear identification for negative earth and grounding circuits while maintaining a professional appearance in automotive, marine, and industrial installations. Supplied in a convenient 100-metre roll, it is an economical solution for workshops, auto electricians, fleet maintenance operators, and large-scale wiring projects.

It is ok
It is decent. Looks like it would work well. It is a little bulky. I bought this one and another one from a different seller. I returned this one due to the thickness of the arm. It was a little bulky. One thing to be mindful of there is no adjustment for the radius of the arm. Depending on how you position it your phone can be quite far away from the screen, it may not bother you, but for me I wanted them as close as possible

Strong Magnet, Great Price!
Mounted in less than 10 seconds. The magnet is super strong and holds the phone through all the bumps the road throws at it. The two thumb screws make for fast angle adjustment. The mount location puts the phone in the perfect spot for viewing without obstructing the view of the road. This phone holder is built well beyond its price point! I will be buying a second one for the wife's Tesla.

Color: Black, Color: Black
Very nice fit and finish. Feels very high quality. Phone charges very quickly and doesn’t heat up as much. It charges through my heavy duty case that i thought i would have to replace as it doesn’t charge on other charges that ive tested. Very impressed.
