These are side-by-side facts taken from each product guide: published specifications, strengths and caveats as their sources state them. This page is not a test, a ranking or a verdict about which model is better.
Clore Automotive Jump-N-Carry JNC660 1700 Peak Amp 12V Jump Starter
Shop and roadside 12-volt starting plus 12-volt accessory power
Clore rates the JNC660 at 1700 peak amps and 425 cranking amps on a sealed lead-acid pack, with 46-inch number 2 AWG leads and a 12-volt accessory outlet. The catch is in the manual: it covers two JNC660 builds, and only the automatic-charging one may be left connected continuously.
