Our verdict
Same clamps, same safety engineering, same brand — the question is purely how much engine and how much cold. The GB40 starts four- and six-cylinder gas engines all day and fits a glovebox; the GB70 adds the headroom that a V8, a small diesel, or a -10°F morning demands, at twice the weight and price. Buy the GB40 for a commuter sedan; buy the GB70 if the word 'truck' or 'below zero' describes your life.

- ✓Four- or six-cylinder car or crossover
- ✓You want it to live in the glovebox
- ✓Winters that rarely drop below the teens
Pick the NOCO if…
- ✓V8 gas, or a diesel up to 6.0L
- ✓Sub-zero mornings are routine
- ✓You want a 12V port for an inflator and a brighter light
