Our verdict
The JNC660 is a professional-grade workhorse that remains a gold standard for reliable, high-amperage jump starting. It is the perfect choice for home mechanics and serious car owners, but those needing a compact, lightweight unit for occasional travel should look elsewhere.
- ✓Extremely high cranking power
- ✓Industrial-grade cables and clamps
- ✓Proven long-term durability
- ✕Heavy and bulky design
- ✕Lacks modern USB charging ports
The Clore Automotive Jump-N-Carry JNC660 is a staple in professional workshops and home garages alike. Built for reliability rather than compact portability, this unit delivers a serious punch with 1700 peak amps, making it an ideal choice for those who frequently deal with stubborn, dead batteries in cold climates. Unlike modern lithium-ion jump starters that prioritize pocket-sized convenience, the JNC660 utilizes a heavy-duty lead-acid battery designed to provide high-cranking power instantly. In testing, we found the industrial-grade cables and clamps to be exceptionally robust, providing a secure connection that feels built to last for years of daily service. This unit is best suited for mechanics or vehicle owners who have the storage space and need a dependable, high-output jump starter that does not rely on sensitive electronics. It excels at starting large displacement engines, though its size and weight make it less convenient for those looking for a portable emergency tool to keep in a glovebox. While it lacks modern amenities like USB charging ports or integrated LED work lights, the JNC660 focuses entirely on the core task of starting vehicles efficiently. It is a no-nonsense, professional-grade tool that values raw performance and durability over modern convenience features, providing consistent results when you need to get back on the road quickly.
