CARTMAN is a direct-to-consumer tool and auto-accessories brand that sells primarily through Amazon. The brand built its reputation in the jumper-cable category, where its 4-gauge booster cables are widely owned and rank in the top tier of Amazon's automotive best-sellers. CARTMAN products occupy the value-tier segment — they are transparently constructed with CCA (copper-clad aluminum) conductors rather than pure copper, a trade-off that lowers cost and weight at the expense of raw conductivity and long-term corrosion resistance. The brand's UL Listing on its cable lineup provides independent electrical-safety verification. Customer service and warranty handling are frequently cited positively in reviews, which is atypical for the price tier.
