20-Foot Extra-Long Booster Cables

20-Foot Extra-Long Booster Cables are extended-length jumper cables for automotive emergency starting. The reference configuration uses a 20 ft cable, 1 GA CCA conductor, 410A current rating, PVC insulation rated to -42°C, and A21-4 heavy-duty clamps.
The 20 ft length provides additional working distance between vehicles. The defined cable gauge, conductor construction, current rating and clamp configuration establish a clear product specification for selection, sampling and repeat production.

20 ft Length
The 20 ft cable provides extended reach between vehicle battery connection points. It is suited to applications where a shorter cable does not provide the required working distance.
Connection Distance
The additional cable length gives greater flexibility when the two vehicles cannot be positioned close together.
Product Control
A fixed 20 ft specification makes cable length easy to confirm during sampling, packaging review and production ordering.

1 GA CCA
The conductor uses copper-clad aluminum construction with a 1 GA specification and a 38.1 mm² conductor area.
445 CCA
The conductor specification is listed as 0.33 × 445 CCA, providing a defined construction reference for production and purchasing documentation.
410A Rating
The reference configuration carries a 410A current rating. Gauge, conductor area, cable length and current rating should be reviewed together when selecting the product.

PVC Insulation
PVC provides the insulating layer around the conductive core and forms the external cable covering.
-42°C Rating
The insulation is specified for temperatures down to -42°C, providing a defined low-temperature reference for product selection.
Cable Diameter
The finished cable diameter is approximately 12 mm, giving buyers a measurable physical specification alongside the electrical and material data.

A21-4 Clamp
The reference assembly uses an A21-4 heavy-duty clamp.
Complete Assembly
The clamp is part of the finished booster cable specification. Cable length, conductor construction and clamp type should match the approved product configuration.
Sample Confirmation
Clamp structure, installation and cable connection can be checked during sample approval before production quantities are released.

Automotive Emergency Starting
The cable is intended for temporary battery-to-battery connection during vehicle emergency starting.
Passenger Vehicles
The 20 ft format provides additional working distance for passenger vehicle applications where battery access or vehicle positioning requires a longer cable.
SUVs and Pickups
The extended length provides more flexibility around larger vehicle layouts and roadside positioning.
Emergency Equipment
The product can be specified for vehicle emergency kits, roadside equipment and automotive service product ranges.

Material Check
Conductor, insulation and clamp components can be checked against the approved material and specification requirements before assembly.
Assembly Check
Finished assemblies can be inspected for cable length, diameter, clamp installation, insulation condition and overall construction.
Production Testing
Mass-production testing is part of the existing product quality process. The manufacturing system is certified to ISO 9001:2015.
Sample Reference
An approved sample provides a physical reference for subsequent production and repeat purchasing.

Product Information
Packaging can identify the main purchasing specifications, including 20 ft length, 1 GA gauge, 410A rating and clamp configuration.
Sample Approval
The sample can be checked against the agreed product specification before bulk production.
Repeat Orders
The approved specification and sample can remain as references for repeat quotations and production orders, keeping the product configuration consistent between purchasing and manufacturing.

For quotation and sample review, specify the required 20 ft length, 1 GA gauge, CCA conductor, 410A current rating, PVC insulation, -42°C temperature rating and A21-4 clamp.
Packaging format, product labeling, carton requirements and other order specifications can be confirmed with the product configuration. The agreed specification provides a clear reference for sample approval and production.
