The Clore Automotive Jump-N-Carry JNC660 is a professional-grade 12V jump starter designed for mechanics, tow truck operators, roadside rescuers, and anyone who demands unflinching reliability from their tools. With 1700 peak amps and 425 cranking amps from its 22Ah Clore Proformer lead-acid AGM battery, it tackles dead batteries in cars, trucks, RVs, boats, tractors, and even lawn mowers without hesitation.
Standout features include 46-inch #2 AWG cables for easy access, industrial-grade Hot Jaw clamps that bite through corrosion, a built-in voltmeter for quick status checks, and a 12V outlet for powering accessories. Real-world users praise its ability to fire up V8 engines, turbo diesels, and vehicles with completely dead or removed batteries, often outperforming lighter lithium packs in multiple consecutive jumps or extreme cold.
Build quality shines with a heavy-duty case impervious to shop fluids, automatic recharging that keeps it perpetually ready, and components optimized for maximum power delivery. While its 18-pound weight adds stability, it feels substantial compared to pocket-sized alternatives, and careful cable management prevents wear over time.
Minor drawbacks like the specific charging plug fit are outweighed by its durability and performance. For those needing a jump starter that performs like a workhorse, the JNC660 delivers unmatched value and peace of mind.
