At 1700 peak amps with 46-inch industrial cables, the JNC660 can start large diesel trucks, commercial vehicles, and farm equipment that lithium lithium jump starters simply don't have the sustained cranking power to handle
The sealed lead-acid battery holds a charge for months without active maintenance, making it reliable for seasonal use—leave it in the garage all winter and it will still start a dead battery in spring
Clore's professional-grade cable clamps are heavy copper jaws rather than the thin-metal clips found on consumer units; they grip battery terminals securely and handle the heat and current of repeated commercial use
Shop and fleet operators trust the JNC660 specifically because its lead-acid design can absorb the abuse of daily multi-vehicle commercial use without the lithium safety management limitations that trigger protection cutoffs
⚠️ Worth Knowing
At 18 lbs, this is a heavy unit that requires two hands and a clear trunk to manage—lithium jump starters like the NOCO GB40 achieve 1000 amps at 1 lb and fit in a glovebox, which is a real convenience advantage for most passenger car owners
The lead-acid battery requires periodic top-up charging (every 30 days if stored) to avoid sulfation damage that permanently reduces capacity; a maintenance charger is a useful companion purchase
No USB charging port, no air compressor, no digital display—this is a pure jump starter with no multi-function extras; the price is largely for raw power and cable quality
What Real Buyers Are Saying
What buyers love
"Run a 4-vehicle fleet of diesel pickups. This thing lives in the shop and has started batteries in -30°C weather without hesitation. Lead acid at this capacity beats lithium in real winter."

"Farm use. Starts the big diesel tractor, the combine header, and the backup generator when they sit all winter. Nothing else I've tried could do all three reliably."

"Used it in my shop for eight years. The clamps and cables still look new. Clore builds these things like tanks."

Common complaints
Heavy and bulky for passenger car use
18 lbs is manageable for a garage or truck bed, but unwieldy in a compact car trunk alongside other gear. Lithium alternatives that fit in a jacket pocket have made the JNC660's footprint feel outdated for everyday carry.

Needs periodic maintenance charging
Lead-acid batteries self-discharge and sulfate if left uncharged for extended periods. Multiple users report capacity loss after storing the unit for a season without a maintenance charge cycle.

No USB ports or auxiliary features
At $150, buyers occasionally expect the multi-function capabilities of similarly priced NOCO units (USB charging, air compressor option). The JNC660 is a single-purpose tool—extraordinary at that purpose, but only that purpose.

ClearPick Verdict
The Clore JNC660 is the right jump starter for commercial operators, farmers, fleet managers, and anyone who regularly starts large diesel engines or works in a shop. Its 1700 peak amps and commercial-grade cables make it the most capable consumer jump starter for heavy-duty applications. Passenger car owners or commuters who want something that lives in the glovebox should look at NOCO's GB40 or GB70 instead—they deliver equivalent capability for most personal vehicles at a fraction of the weight.
