Clore Automotive Jump-N-Carry JNC660 - Best Professional-Grade Reliability

The Clore Automotive Jump-N-Carry JNC660 represents the professional's choice in portable jump starters, utilizing a traditional lead-acid battery that delivers consistent 1700 cranking amps. This design provides steady, reliable power that many professionals prefer over lithium-ion models, particularly for frequent use. The 68-inch heavy-duty cables offer exceptional reach, making it easier to access batteries in large vehicles or awkward engine compartments. A built-in voltmeter allows for quick battery condition checks, while the rugged construction withstands shop environments. Unlike sealed lithium units, the JNC660 features a user-replaceable battery, significantly extending its usable lifespan.

While heavier than lithium alternatives at 18 pounds, the weight contributes to stability during use. The unit maintains charge well when stored, though it requires more frequent recharging after use compared to lithium models. Professionals will appreciate the no-nonsense design, proven reliability, and ability to handle multiple jumps per charge. The lack of USB charging ports reflects its focused design as a dedicated jump-starting tool rather than a multi-purpose device.
