Noone 2-Gauge 20ft Heavy-Duty Jumper Cables with Smart-7 LCD and Reverse-Polarity Protection, 600A

NOONE 2 Gauge 20-foot jumper cables are heavy-duty booster leads with Smart-7 reverse polarity protection and an LCD monitor for safer, more reliable jump starts.

When a vehicle battery fails, having robust cables that deliver high current and reduce user error matters. These NOONE cables combine thick 2-gauge conductors and a long 20-foot reach with an S7 Smart-7 protector that shows battery voltage and flags incorrect connections. Built for harsh temperatures and equipped with insulated, UL-listed clamps, this kit also includes a carry bag and gloves so you’re ready when roadside help isn’t available.

How do these cables deliver the power a dead battery needs?

The 2-gauge copper conductors provide low resistance for strong current flow, supporting up to 600 amps of instantaneous current to quickly transfer charge between batteries. The heavy vinyl jacket keeps the cables flexible in cold or hot weather, ensuring consistent conductivity.

• 2-gauge wire for high conductivity and faster power transfer
• Rated for up to 600A instantaneous current
• Vinyl coating stays flexible from -40°F to 140°F
• 20-foot length reaches a wide range of vehicle layouts

What safety features reduce the risk of sparks or damage?

NOONE’s Smart-7 protector includes an LCD voltage readout so you can monitor battery status while charging. Reverse polarity protection prevents damage from incorrect connections by illuminating a red indicator if clamps are attached the wrong way.

• LCD display shows battery voltage during jump starting
• Reverse polarity alarm warns of miswired clamps
• Patented UL-listed clamps have non-conductive rubber covers for insulated handling
• Designed to minimize short-circuit and spark risks during use

Will these cables work with my vehicle—cars, trucks, and SUVs?

The 20-foot reach and heavy 2-gauge construction make them suitable for a broad range of vehicles, from compact cars to large SUVs and many trucks. The length helps bridge long engine bays or awkwardly placed batteries without needing to reposition vehicles.
