TL;DR Stated 4 AWG with CCA conductor confirmed by distributor disclosure · not misrepresented, but not pure copper. No independent gauge measurement found. T-Prene thermoplastic elastomer jacket is manufacturer-rated to −94°F and community-reported to stay flexible in winter (no named temperature). Polar-Glow clamps are top- and side-post compatible. Adequate for passenger-car and light-truck emergency use at 25 ft; the length-gauge combination is marginal for sustained heavy-diesel cranking. Passive cable · no inline reverse-polarity protection.
Road Power states 4 AWG on the 25 ft cable · CCA conductor confirmed by distributor disclosure (Empire Rigging lists model 86620104 explicitly as CCA) and corroborated by sibling-SKU distributor data; no independent gauge measurement exists. T-Prene thermoplastic elastomer jacket is manufacturer-rated to −94°F; community evidence confirms the cable stays pliable in winter, though no named temperature is cited. Polar-Glow ergonomic clamps are described as top- and side-post compatible, with copper contact surfaces per owner reports; a small number of owners report a crimp failure requiring re-crimping. Passive cable · no inline reverse-polarity electronics. Length at 25 ft is marginally long for a 4 AWG CCA conductor when sustained heavy cranking loads are applied.
Right pick for a passenger-car or light-truck owner who needs a long-reach emergency cable and occasionally jumps in awkward parking situations · the 25 ft length handles nose-to-tail and side-by-side scenarios where 16·20 ft cables fall short, the T-Prene jacket holds up in cold-weather climates, and the UL Listing provides independent construction verification. Skip if the vehicle is a heavy-duty diesel or large commercial truck · the 4 AWG CCA conductor at 25 ft is marginally undersized for sustained 400 A cranking, and the "commercial-duty" label overstates the use case. Also skip if a dedicated storage bag matters · no bag is included.
Passive electrical conductor with T-Prene thermoplastic elastomer jacket · no chemical exposure pathway in normal use. Passive cable with no reverse-polarity indicator or inline protection electronics. CCA conductor recycles poorly · separating the copper coating from the aluminum core is not economically viable at most scrap facilities; insulation is not routinely recycled. The UL Listing covers construction safety; it does not certify sustained cranking current capacity at the stated gauge.
CCA (copper-clad aluminum). Distributor Empire Rigging explicitly lists model 86620104 as 'CCA Polar,' and sibling SKUs from the same Road Power family are uniformly disclosed as CCA by multiple B2B distributors. The product listing says 'copper' without a qualifier · that language does not indicate pure copper. CCA has higher electrical resistance than solid copper at the same stated gauge.
T-Prene is Road Power's trademarked name for a thermoplastic elastomer (TPE) jacket compound. Multiple retailer descriptions cite a manufacturer cold-flex rating of −94°F (−70°C), which exceeds the performance of standard PVC insulation. Community evidence confirms the cable stays pliable in winter use, though no specific temperature is named.
Yes · UL Listing is confirmed across multiple retailer product descriptions for this model. UL Listing verifies the product meets electrical safety construction standards. It does not independently confirm the stated AWG gauge.
Marginally. The brand markets these as 'commercial-duty' and community reviews confirm use on Utilimaster diesel delivery trucks, but 4 AWG at 25 ft produces more voltage drop under sustained high-amperage cranking than a shorter or heavier-gauge cable. A 2 AWG cable is more appropriate for regular heavy-diesel use.
No dedicated bag is included. The cables arrive in a cardboard box with a handle, which functions as initial storage. Multiple owners purchased a separate cable bag for trunk storage.
