Match the starter to your engine
A jump starter is rated by the largest engine it can start. Pick one rated above your engine's displacement, with room to spare if you live where winters are cold, because cold engines take more current to crank. Your engine size is in the owner's manual.
| Your vehicle | Pick |
|---|---|
| Motorcycle, ATV, lawn tractor, small car up to 4.0 L gas | GB20 |
| Car, crossover or half-ton truck up to 6.0 L gas | GB40 |
| V8 truck up to 8.0 L gas, diesel up to 6.0 L | GB70 |
| Heavy-duty diesel up to 7.0 L, boats, fleets | GB150 |
NOCO designs all four for 12-volt lead-acid batteries only, and builds the Boost range with spark-proof clamps and reverse-polarity protection.
