Product Features

Strong and Safe Clamps

The jumper cables feature four giant alligator clamps with strong jagged teeth and springs that provide excellent grip force. The jaws are engineered with a reinforced structure and well-designed to provide a firm, secure grip on both top-post and side-terminal batteries. The clamps are coated with insulating rubber material to prevent electric shock and protect user safety.

20 Feet Jumper Cables

The cables have an extremely long length of 20 feet, suitable for use with SUVs, full-size cars, mid-size cars, and compact cars. The cables are made with insulating material to prevent rust and corrosion, ensuring effective insulation. The thick-gauge Copper Clad Aluminum cables maintain flexibility even in extreme cold, providing reliable performance when needed most.

UL-Listed and Qualified Quality

The cable surface is made with premium PVC which resists freezing, cracking, and folding, and prevents tangling. Each jumper clamp has undergone rigorous testing and passed UL certification, demonstrating excellent performance under extreme temperature conditions (-40°F to 140°F). The thick vinyl coating resists wear and tearing, protecting the internal wire and enhancing safety and durability over time.

Convenient Storage and Carrying

The jumper cables come with a 600D Oxford fabric storage bag that is tough, spacious, and features a smooth zipper for easy access. This allows for neat organization and convenient carrying or storage in any location.

Safety Information

SAFETY PRECAUTIONS:

• Always wear eye protection.
• Do not smoke near batteries.
• Ensure the vehicles do not touch each other.
• Both vehicles must have the same electrical system voltage.
• If available, place a damp cloth over the battery vent caps.
• Do not lean over the batteries during the procedure.
• Keep sparks, flames, and metal objects away from batteries.

CONNECTION STEPS:

1. Connect the positive (+) cable (usually red) to the positive (+) terminal of the dead battery.
2. Connect the other end of the positive (+) cable to the positive (+) terminal of the booster battery.
3. Connect the negative (-) cable (usually black) to the negative (-) terminal of the booster battery.
4. Connect the other end of the negative (-) cable to a clean, unpainted metal part of the engine block or chassis of the stalled vehicle — NOT to the negative battery terminal.
5. Start the engine of the booster vehicle and let it run for a few minutes.
6. Attempt to start the stalled vehicle.
7. If the engine does not start within 30 seconds, stop and recheck connections.
8. Once started, remove the cables in reverse order:
   1. Negative cable from the engine block/chassis of the stalled vehicle.
   2. Negative cable from the booster battery.
   3. Positive cable from the booster battery.
   4. Positive cable from the previously stalled vehicle's battery.

WARNING:

Batteries produce explosive hydrogen gas. Keep away from sparks, flames, and heat sources. Ensure proper ventilation when charging or jump-starting in enclosed spaces.
