Cartman Booster Cable 4 Gauge x 20Ft in Carry Bag (4AWG x 20Ft) UL-Listed

These are clearly much better than the typical ones found in an auto parts store. I purchased these to keep in my RAM. The more common, smaller gauge cables at best struggle to boost the heavier batteries found in these types of vehicles, so heavier gauge cables are a must. I see some ridiculous reviews complaining about the cables being copper clad aluminum as opposed to solid copper cables. That's simply an example of having a little, but not enough knowledge. The Service Entrance cables from the utility pole to your home are strictly aluminum - not copper and not even copper-clad aluminum. For the person looking to boost most types of vehicle batteries encountered, there's just simply no need for anything more than these. These are "heavy duty" in the sense that they are a larger gauge than most of the more commonly available smaller 6 or 8 gauge cables found in retail stores. (Reminder...the smaller the number, the larger the gauge and thicker the wire....4 gauge is thicker than 8 gauge). These are built well and the handles are insulated well. The clamps are versatile and can be clamped straight-on or from the side, accommodating most battery post styles. The additional length is a huge plus, especially with a larger vehicle such as mine. You don't have to worry about positioning the vehicles just right to use them like most sets of cables, which is sometimes difficult when a battery dies. They came with a pair of gloves and a small wire brush for cleaning terminals. Not essential, but a nice touch. The carrying bag is sufficient for a typical few-times-per year use, and the cables should provide years of use if stored responsibly and not used to tie-down cargo or if hastily rolled-up, tangled and thrown in a trunk like most lazy people do. If you are performing recovery service you would need a more durable carrying case. Another thing....they are not intended to be pulled-apart, as the jacket is not perforated and will likely tear and expose the conductors. I see other reviewers peeled them apart and then complained the conductors become exposed. It's like peeling apart the cord on your laptop or table lamp - why would you do that? Just because you see a line between the two, doesn't mean you can pull them apart. If you want cables that are completely separate you can find and purchase them that way. Not sure why someone would alter a product then ding it for failing. I wouldn't pay much attention to some of the over dramatic negative reviews or the one's complaining about copper-clad vs pure copper conductors. Those differences are applicable for precise electronics where every watt and milliamp count and extreme efficiency is needed. Boosting a battery requires sufficient voltage and current for a relatively short time and nothing more. And besides, do you know what these would cost if they were pure copper? I spent 10 years in the electrical trades and now do design work which entails calculating current, voltage drop and ampacity. In my opinion and experience, these are a good purchase overall for what they're designed for.NOTE: I purchased this item on Amazon for full price and have no affiliation to the seller. I try to write helpful, unbiased and insightful reviews because I also read reviews prior to making my own buying decisions. I notice many reviews lack helpful information, are not well written or give poor reviews based on not reading directions, inexperience or failing to read the product details prior to purchasing. Writing valuable reviews helps pay it forward.

I ordered these cables so I would have a set for our second car and ended up ordering a second set for my car! The cables are nice and long at 20 feet. The clamps are covered around the edges to prevent any unnecessary contact. There is a very clear instruction card attached to the cables for someone who does not know the sequence in which to connect. A very nice bag is included which has plenty of room along with a set of gloves and even a brush for cleaning corrosion of of the battery terminals. Totally worth it!I used these the other night in -32 C weather to boost a co-workers car. Worked great! Much better than my previous set from Canadian Tire. These ones were still pliable even in that cold of weather. I was able to unwined them and boost my co-workers car with no problem. My old set from Canadian Tire was kind of a dud. The previous winter when I went to use them on a cold day chunks of the "rubber" insulation snapped off when I went to straighten them out.Highly recommended after real world use on a very cold day!

This is a 6-meter, gauge 4 cable. For 24 dollars. This is all that's needed for this product to be a 5-star must have.The utility of having such a long cable is being able to boost a car that is parked forwards into a tight space with no way to bring another car close enough. This will easily cover the entire length of most Sedans. Gauge 4 ensures you can use this cable safely with the most demanding engines.I can't say this enough: for 24 dollars (no strings attached, this is as well built as any other premium cable), this is a steal. Get it.

It's much thicker wire than standard cables & is long enough to reach over my car from behind if I needed a jump from an awkward position. Good quality jaws and stored easily in my mini spare tire.

Read the reviews for this product and I can concur with everyone else that this is an excellent product. Cables are heavy duty and the length is great. Product came with a bag and they even through in some extra gifts. When I looked in the bag, there were some free gloves and a wire brush to clean the battery terminals. So not only can you get a great product delivered to your door, they go the extra mile to make you a happy customer. So now I am actually looking forward to a dead battery to use these cables. I am sure my 2001 F350 van won't let me down.
