Review on 🔋 THIKPO G420 Heavy Duty Jumper Cables with UL-Listed Clamps | 600A Peak Booster Cables Kit for Car, SUV, Trucks | Up to 6-Liter Gas & 4-Liter Diesel Engines | 4Gauge x 20Ft by Matthew Allen

Upon receipt, however, the cables feel suspiciously light for 1ga pure copper. I pulled back the rubber grip and looked at the bruise. You can see it in the photo. Silver tips peek out from under the copper plating where the strands are cut. Copper is never silver in color. This is a CCA cable. If you only need CCA cables, they seem good but overpriced. I wanted pure copper, paid a premium but they are not genuine. Now they are returning to Revane. Buyer Warning!
