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.

Premium OFHC Copper for Maximum Conductivity

At the heart of this 4B&S twin core automotive cable is high-purity OFHC copper, which provides lower electrical resistance compared to standard copper conductors. This results in improved efficiency, reduced heat generation, and better voltage retention across longer cable runs. Whether powering battery systems, inverters, chargers, or auxiliary equipment, the cable helps ensure stable and consistent power delivery.

The flexible multi-strand conductor design also improves durability in environments subject to vibration, movement, and temperature fluctuations. This makes it ideal for installations in vehicles, boats, caravans, heavy machinery, and renewable energy systems where long-term reliability is critical.

Ideal for 12V, 24V and 48V Electrical Systems

With a conductor size of 20.29mm² per core (4B&S), this cable is commonly used for medium to high-current applications requiring both positive and negative conductors within a single cable assembly. The twin core design reduces installation time while providing additional protection against abrasion and environmental exposure. It is suitable for modern 12V automotive systems, 24V commercial vehicle installations, and 48V lithium battery applications.

Common Applications Include:

  • Dual battery systems in 4WDs and touring vehicles
  • Caravan and camper trailer battery installations
  • Marine battery banks and onboard electrical systems
  • DC-DC charger and battery charger wiring
  • Solar battery storage and off-grid power systems
  • Inverter installations and auxiliary power distribution

Built for Harsh Australian Conditions

Manufactured to comply with AS/NZS 1125 conductor standards and AS/NZS 3808:2000 insulation requirements, this cable is designed to handle the challenges of demanding automotive and industrial environments. The V90 insulation offers excellent resistance to heat, abrasion, oils, fuels, and common automotive chemicals while maintaining flexibility for easier installation.

The twin core construction keeps positive and negative conductors neatly contained within a durable outer sheath, helping to reduce cable clutter and improve protection. This makes it particularly popular for long cable runs between batteries, chargers, solar systems, and auxiliary equipment.

Love and Beware
This is a fabulous product but be aware that if you wash you face vigorously and splash ANY oil on your walls it will stain. I love it but hate the spots that I sometimes get. I have tried a little diluted dish soap but it doesn’t really help.

Whoa- I can’t believe this!
I wanted to try this product for a very specific purpose, I have been looking at facial cleansing wipes to use occasionally at bedtime instead of stripping my face by doing a full wash with cleanser and water. I rarely wear makeup, I spend my energy on finding the best skincare products for my skin and sunscreen. So at bedtime usually, I’m just taking off sunscreen and the day’s grime, or if I didn’t go out, the day’s moisturizing products. I tried several brands of moist facial cleansing wipes, and they left behind a greasy film and my face still feels like it needs a full wash. I would never want to skip properly cleansing my skin, and I usually do a full routine while I shower, but it would be nice to be able to occasionally do something quicker and more convenient without sacrificing on quality. I was hoping this product might cleanse well without needing to be rinsed or breaking me out on occasions where I want something quick and convenient, or maybe am travelling and need a basic routine. Wow, this product is not only perfect for that, it actually makes my skin soft and clean, you’d never know I skipped my regular cleansing and just used this Bioderma product with a cotton pad before my nighttime moisturizers/serum. It completely takes off the day’s water resistant facial sunscreen and any sweat or grime and leaves my skin very clean, soft, not dry, and it feels like there is no residue whatsoever. I also don’t break out or get clogged pores, it is just a clean, soft texture. One cotton pad with product is all takes for my entire face to look and feel just as clean as if I had used my regular products (a cleansing balm followed by a foaming cleanser and lots of rinsing with water). I have used this micellar water quite a bit since receiving it, and have not broken out or had clogged pores from “cutting corners” so to speak. And it cleanses very well. I can’t believe how well it cleanses without needing to be rinsed, without irritating my skin, without clogging pores or causing breakouts, and is suitable to use and then put on my serum and nighttime moisturizer. I’ve even used it the next morning to remove the nighttime moisturizers and then put on my SPF. I worried that I was going to cause my skin not to look as good if I didn’t properly wash and rinse with water but this product is so amazing. I have not yet used it to see how well it removes makeup since I rarely wear any, but just for skincare and cleansing without a full wash with regular water, it is so amazing. Not going to sugarcoat it, this is me wanting a convenient routine when I travel but this is also me being lazy on nights when I’m very tired or mornings when I am in a hurry. I consider this one of my few holy grail skincare products. I have picked up a smaller size for travel. I will keep this on hand always. I’m not even looking at moist wipes anymore. (This product is more gentle and leaves no residue as compared to a dermatologist recommended brand of face wipes). I’m most surprised that it cleans my face so thoroughly and that not rinsing does not cause any irritation or breakouts. Just wow. Totally worth the price. I was going to try other brands but this product has been so good there is no need to.

Indispensable!
Scent: Unscented, Size: 25 Count (Pack of 4)
I love these so much that they are part of my monthly subscribe-and-save program. They have absolutely no scent, which is great, because too many products are over-perfumed. They take off all of my makeup gently. There is no stinging or drying sensation. The cloths are well-sized and the package stays shut when not in use- the cloths do not dry out. After I use a couple of these each night to take my makeup off, I follow up with a gentle, moisturizing facial cleanser. My skin is soft, clean, and happy. I highly recommend these!

A Staple in my Skincare Routine
Scent: Unscented, Size: 25 Count (Pack of 3), Scent: Unscented, Size: 25 Count (Pack of 3)
I've been a huge fan of micellar products ever since they came onto the US market and these Simple Micellar Makeup Remover Wipes are no exception! Simple products are known to be gentle and easy on the skin. These wipes stay true to the brand and feel great on the skin! I have combination, sensitive skin and over the years, I've become quite diligent in taking my makeup off before bed. Although I have tried countless popular brands in the past, these Simple Micellar Makeup Remover Wipes are the ones I keep coming back to time and time again. These wipes are my first step of action in removing my makeup and they do a pretty great job of taking off everything. I usually hold the wipe over my eye area for a few seconds to allow the makeup to break down and come off onto the wipe--I've found that this does a good job of removing my mascara, eye liner and shadow. These wipes do not cause any irritation to the eye area and are great to use on the sensitive skin of the face. To take off stubborn or waterproof makeup, I just apply a liquid eye makeup remover directly onto the wipe and have found this to be the easiest and least wasteful method. I usually wash my face afterwards with a gentle cleanser and continue on with my skincare routine. However, on the nights I'm really tired, I rely on these wipes to remove all of my makeup. These wipes do not leave any type of chemical residue behind and make my face feel fresh and clean. The Simple Micellar Makeup Remover Wipes are a staple in my skincare routine. I keep one pack in my bedside table for easy access on the nights I'm too lazy to wash my face, one in my vanity, and another in my gym bag--I clearly like to stock up! I highly recommend these wipes; they are a must try for everyone!
