Clore Automotive Jump-N-Carry JNC660: What to Know
This is the one genuinely different technology in this guide. Where the NOCO, HULKMAN, and GOOLOO packs use lithium-ion cells, the JNC660 uses a sealed AGM lead-acid battery Clore calls its PROFORMER battery. That difference matters in practical terms: no USB charging ports, no lithium thermal-runaway or hot-car storage concerns, and a weight of about 18 lb versus 2 to 4 lb for the lithium packs here. Clore also builds in an automatic internal charger meant for the unit to stay plugged in on a shelf between uses, rather than being tossed in a trunk and forgotten.
Clore rates the JNC660 at 1700 peak amps, and notably also publishes a 425 cranking-amp (CA) figure, one of the only jump starters in this guide to state both numbers, which lets buyers actually compare it against a battery's own CCA rating instead of relying on an unverifiable peak-amp claim alone. It ships with heavy #2 AWG, 46-inch cables, a heavier gauge than the thinner leads on most lithium packs, built to sustain high current draw on big V8 or diesel starts rather than deliver a brief spike.
There's no USB charging, no flashlight, and no diagnostic display beyond a simple charge-status meter, it's a single-purpose jump-start tool. That focus is exactly why it's widely used as a shop-standard reference unit that mechanics and reviewers often compare newer lithium packs against: a lead-acid design like this doesn't fade in cold weather or require the careful voltage-cutoff protection lithium cells need.
