Spartan Power Heavy Duty Jumper Cables with Alligator Clips, 100% Pure Copper Wire, Positive & Negative Leads Battery Cable, Made in The USA - 1/0 AWG Gauge Cable, 10 ft

Does this cost a little more? YES and it is worth it! Copper conductors, great clamps, incredible quality!Absolutely no regrets.

After my very cheap copper-plated jumper cables failed for multiple reasons (including that copper plating corroded and wore off), I decided to get some high-quality jumper cables that would last long time. These jumper cables claim to be high-quality and made of all copper, and having received them today, I think that the claims are justified. Everything about the product checks out to specs. Some of the negative reviews reported weak crimping and connections between the cable and the jumper clamps, but I think those reviews are wrong. The cables connect to the clamps with a Panduit connector S4-56R made of copper with a slight tin plating to reduce corrosion (one of the accompanying pictures shows the connector). The crimping connection to the wire seems very solid. The connections out to the jaws of the clamp are also all copper and appear to be quite thick and heavy duty. The body of the clamp is made of a nonconducting plastic that seems very solid. I would recommend the product and buy it again if I needed another set.

Very nice, Very Happy!

Excellent quality!

Beefy USA quality. Pure copper wire and aggressive clamps. These cables should give me many years of service.

Can't review something with no history. Ask me in a few years and I will give an honest review. So catch me in few years.

Used it once to jump start a vehicle and it works as advertised.

In my opinion,, there is simply no competition to compare to these cables. First, they are made in America; the quality reflects the excellence expected from such a great nation. The flexibility is terrific, yet the outer protective covering has tremendous integrity, offering the impression that it will endure and keep the copper protected. The clamps are amazing! They are strong, beautiful copper teeth, and finally, a manufacturer exemplifies brilliance by taking advantage of the greatest contact patch available through the distribution strip that allows power to travel through both sides of the clamp. In the end, this is basic logic as we buy such cables to transfer energy and not restrict it at some bottleneck point. I am so happy I chose to pay for this amazing tool and not cut corners. Just for fun, I connected them to a Kubota L39 4 cylinder diesel TLB with a battery that read a hair over 2 volts. I connected it with these cables to a loose (carried it by hand-no alternator supporting increased current or amperage). The preheater light went right out quickly and it spun to life immediately. Very impressive at 23 degrees Fahrenheit, and after having sat for approximately three weeks since last jumped.

Super duty. These arent your normal or even the HD cables you buy. These are to jump start a dead planet or star

Great - true to listing

I occasionally jump from a diesel truck with dual engine batteries to another boat or vehicle. The best jumpers from the local automotive shops pack easily, but they will melt or even catch on fire if the other battery is low or dead. These cables are heavy and robust. I also appreciate the separate positive and negative cables for ease of handling. Get these if you intend to jump from big diesels. If you want something that packs lightly or in a small space, they may not be for you,
