AutoChat 2-Gauge 20 ft Jumper Cables — Heavy-Duty 800A Rated, Insulated Clamps & Carry Bag

AutoChat Heavy Duty Jumper Cables are 2-gauge, 20-foot booster cables built for reliable jump starts on 12V and 24V vehicles, including large engines up to 7.0L gas and 5.0L diesel.

When a battery fails, the right jumper cables get you moving again quickly and safely. These AutoChat 2-gauge, 20-foot cables combine thick conductors, rugged clamps, and weather-resistant insulation so you can jump-start cars, SUVs, trucks, and light commercial vehicles in a wide range of conditions without fumbling or risking poor contact.

How do these cables handle heavy-engine vehicles?

The 2-gauge copper core and 20-foot length are sized to deliver high instantaneous current—up to around 800 amps—for demanding starts. That capacity makes them suitable for large gasoline and diesel engines while keeping voltage drop low across the run between vehicles.

• 2-gauge thickness for strong current flow
• Rated to withstand approximately 800 A instant surge
• Works with 7.0L gas and 5.0L diesel engines
• Compatible with 12V and 24V electrical systems

Are they safe and easy to use during roadside jumps?

Yes. Each cable has oversized clamps with reinforced springs and serrated jaws to create a secure, low-resistance connection that minimizes arcing. Insulating rubber covers on the clamps and thick vinyl sheathing on the cable protect fingers and reduce corrosion risk for safer, longer-lasting use.

• Large alligator clamps with jagged teeth for firm grip
• Insulated handles and rubber clamp covers for user safety
• Thick vinyl outer jacket resists rust and abrasion
• Comfortable, non-slip handles for straightforward attachment

Will these cables work in extreme weather or tangle-prone situations?

AutoChat designed the cables to remain flexible and functional across a wide temperature range, so cold mornings or hot summers won’t make them brittle or sticky. The construction minimizes internal memory and tangles, making deployment quicker when every minute counts.

• Tested to operate between -40°F and 140°F
• Durable jacket reduces kinking and tangling
• Long 20-foot reach keeps vehicles positioned safely apart

What else is included and how do these extras help?

AutoChat packages the cables with practical accessories to make roadside assistance neater and more hygienic. A compact carrying bag keeps everything organized, gloves protect hands during cold or dirty jumps, and a brush helps clean terminals for better contact.

• Carry bag for tidy storage and quick access
• Protective gloves to shield hands from grime and cold
• Terminal brush for removing corrosion and improving conductivity
• One complete 2-gauge, 20-foot jumper cable set included
