JNC660 vs JNC770R Key Differences
Peak Amps Output
Edge: Tie
Both the Clore Automotive Jump-N-Carry JNC660 and the JNC770R deliver identical peak current ratings. Each unit provides 1700 Peak Amps to crank dead batteries. This shared specification ensures that neither unit has a raw power advantage over the other for starting engines. You can expect similar performance in terms of maximum burst current regardless of which model you choose for your vehicle fleet.
Cable Length
Edge: Clore JNC770R 1700A Jump Starter
The JNC770R includes significantly longer cable leads than the JNC660. The JNC770R features 68-inch heavy-duty 2 AWG welding cable leads, providing extra reach. In contrast, the JNC660 comes with 46-inch heavy-duty #2 AWG cables. If you need to jump-start vehicles from a greater distance or in tight spaces where reach is limited, the JNC770R offers a clear practical advantage with its extended cable length.
Built-in Charger
Edge: Clore JNC770R 1700A Jump Starter
The JNC770R includes a built-in 3A automatic charger to maintain the internal battery, whereas the JNC660 does not list this feature. Instead, the JNC660 provides a DC outlet to power 12V accessories but lacks an integrated charging system. If you want a unit that can top off its own charge automatically without external equipment, the JNC770R is the better choice. The JNC660 requires a separate charger.
Physical Dimensions
Edge: Clore Jump-N-Carry 1700A 18lb Unit
The JNC770R is physically larger than the JNC660 in all dimensions. The JNC770R measures 22 inches in length, 18 inches in width, and 9 inches in height. The JNC660 is more compact, measuring 16.3 inches in length, 14.1 inches in width, and 5.1 inches in height. If you need a more portable unit that fits into smaller storage compartments, the JNC660 is the superior option due to its smaller footprint.
Weight
Edge: Clore Jump-N-Carry 1700A 18lb Unit
The JNC660 is lighter than the JNC770R, weighing 18 pounds compared to the JNC770R's 23 pounds. This five-pound difference may matter if you frequently carry the jump starter to different vehicles or locations. The JNC660 is easier to lift and maneuver. If portability and ease of handling are priorities for your daily routine, the lighter JNC660 provides a distinct advantage over the heavier JNC770R.
