NOCO Boost XL GB50 1500A UltraSafe Lithium Jump Starter
Mid-tier 1500A 12V lithium jump starter bridging the compact GB40 and heavy-duty GB70.

Who it's for
Owners of larger sedans, V6/V8 SUVs and light trucks who want margin over the GB40.
Key features
- 1500A peak
- up to 7.0L gas

What to know before you buy
- The middle child: compact car → GB40 is enough; big diesel → get the GB70. Rated up to 7.0L gas / 4.5L diesel.
