TL;DR Stated 2 AWG at 20 feet, with no independent measurement to confirm it. Conductor material is undisclosed, and both the price and shipped weight point toward copper-clad aluminum rather than pure copper. PVC insulation is brand-rated to -40F to 140F, unconfirmed by independent testing. At this gauge and length, coverage runs from compact cars through light trucks with headroom to spare, and the inline Smart-7 module (LCD voltage display, reverse-polarity indicator) is a genuine standout feature at this price.
This is a 2 AWG, 20 foot cable pair built around an inline electronics module rather than passive metal alone. Clamp onto a dead battery and a running vehicle's terminals in the usual order; the LCD readout shows live voltage and a red indicator lights if the clamps are reversed before current flows. The brand states a 600 amp instantaneous rating and a vinyl insulation range of -40F to 140F. No independent gauge measurement, teardown, or cold-weather report exists yet for this model, so real-world durability stays unconfirmed beyond the brand's claims.
Right pick for an owner who wants reverse-polarity protection and a voltage readout in the trunk, at 2 AWG capacity covering compact cars through light trucks. Skip it if you need independently verified gauge and conductor purity: this SKU's conductor is undisclosed with no third-party measurement, and a confirmed pure-copper teardown is the safer pick for that priority.
No chemical exposure pathway. This is a passive electrical conductor with a low-voltage electronics module, and no SDS applies. The reverse-polarity indicator is a genuine safety feature a plain cable lacks. The undisclosed conductor is likely copper-clad aluminum, which recycles less cleanly than pure copper, and the PVC insulation has a shorter flex life than EPDM rubber.
NOONE does not state the conductor material anywhere in the listing for this cable pair. The price and shipped weight both come in below what a pure 2 AWG copper conductor of this length would cost and weigh, which is consistent with copper-clad aluminum. No brand admission, teardown, or third-party lab test confirms this either way, so the conductor should be treated as likely CCA rather than confirmed pure copper.
The inline module sits between the clamps and the cable, with an LCD screen that displays live voltage and a red indicator that lights if the clamps are connected backward, before current is allowed to reach either vehicle. NOONE does not disclose whether the module also cuts current automatically on a reversed connection or only displays a visual warning, so treat it as a confirmed visual indicator rather than a documented automatic cutoff.
NOONE markets this length and gauge combination as compatible with compact cars, mid-size and full-size cars, vans, large SUVs, and trucks. At 2 AWG, the conductor is a heavier gauge than the 4 AWG size standard for passenger cars, which gives extra voltage-drop headroom across that range, though it falls short of the 25 to 30 foot lengths typically used for heavy-duty diesel trucks or RVs.
No independent gauge measurement, caliper teardown, or SAE J1494 compliance citation has been located for this specific NOONE model. The 2 AWG figure printed on the box and listing is the brand's own stated claim only. Buyers who need a verified gauge before they buy should look for a jumper cable model with a published third-party measurement, such as an independent reviewer's teardown.
Yes. The package includes a zippered carry bag printed with the NOONE brand name and a pair of knit work gloves, in addition to the two clamps and the inline LCD and reverse-polarity module. No independent community reports on the long-term durability of the bag or gloves have been found yet for this specific SKU.
