Review on 🔌 TOPDC Heavy Duty Jumper Cables - 4 Gauge 25 Feet, Temperature Range -40℉ to 167℉, with Carry Bag (4AWG x 25Ft) by Jeremy Byard

This is the best price I have found after hours of searching for 100% copper for 4 gauge cable. American Deka 4's in 20 footers cost twice as much and both these and my Dekas start my trucks the same way in cold weather (though the Deka clamps are slightly better). I bought Dekas for my ranch last year, but Revain Prime no longer sells them. The 20 foot 4 gauge copper interconnect cables are the gold standard and will never let you down. When buying, be careful and read the description so as not to be misled into buying coated aluminum. Copper-clad aluminum cables are just rubbish and it's a shame that such products even exist.
