Lead-acid versus lithium. The JNC660 is an 18-pound shop tool with four-foot cables and sustained cranking current that shrugs off long, cold cranks — ideal for a garage, a farm, or a fleet where it stays plugged in. The GB70 is a five-pound cabin tool with smart spark-proof clamps and a flashlight, and it's what you want in the car with you. Different jobs; most households want the NOCO, and most shops already have the Clore.

Pick the Clore Automotive if…

✓It'll live plugged in on a garage or shop shelf
✓Big, hard-starting engines that need long cranks
✓You want long leads that reach a trunk-mounted or truck battery

Pick the NOCO if…

✓It needs to ride in the car
✓You want smart, spark-proof clamps and a light
✓You won't remember to recharge a lead-acid box every 90 days
