Real User Field Analysis
The NOCO Boost Plus GB40 has earned its reputation as the benchmark personal jump starter for everyday drivers. Unlike clunky traditional jumper cables that require relying on the goodwill of a passing motorist with jumper cables, the GB40 empowers you to get your engine cranking independently in under 60 seconds.
Roadside Safety & Performance
With 1,000 peak amps, the GB40 easily tackles gas engines up to 6.0L and diesel engines up to 3.0L. The standout engineering highlight is NOCO’s UltraSafe reverse-polarity protection: if you accidentally hook the red clamp to negative and black to positive, the unit simply refuses to activate and flashes an error light—no sparks, no smoke, and no fried alternator circuits.
