[8-Gauge Tangle-Free Cable] This cable features heavy duty 8-gauge tangle-free cable construction for safer use. In addition, the coating keeps the cable flexible in cold weather (-25°C/-13°F) [Compatibility] Jumper cables have sufficient CCA for good electrical conductivity. Jumper cable clamps are suitable for 12-24V batteries. Ideal for mid-size cars, light pickup trucks and light recreational vehicles [Safe and Reliable] The adapter shell is made of ABS plastic material, the plug is made of pure copper material, and the outer layer of the cable clamp is wrapped with non-conductive rubber, which increases the conductivity and ensures safety and endurance.
