Pros
- Switchable 12V and 24V output covers everything from pickups to commercial diesel trucks and heavy equipment
- Cranking output is among the highest in NOCO's portable lithium lineup, designed for big-displacement diesels
- Spark-proof clamps and reverse-polarity protection make it safer to hand off to less experienced drivers
- Doubles as a USB power source and built-in LED work light for roadside use
Cons
- Significantly heavier and bulkier than consumer-grade jump starters, less practical for casual use
- Premium price point that's hard to justify unless you actually need 24V or repeated heavy-diesel starts
