Ranked #3 in Best Portable Jump Starters

NOCO Boost HD GB70

4.5

1 source$29.95as of Sep 25

Big-engine and diesel owners want the Boost HD GB70. Its 2000A reliably cranks 8.0L gas and 6.0L diesel motors, the 40-jump reserve means you can go months without thinking about it, and the rugged cables shrug off shop and trail abuse. Weight, bulk and a dated micro-USB charging port are the costs.

Strengths

— 2000A peak output covers 8.0L gas and 6.0L diesel engines, including big trucks and SUVs
— Up to 40 jumps per charge so it rarely needs a top-up in the trunk
— 400-lumen flashlight with seven modes including SOS and strobe

Watch-outs

— Heavy at roughly 5 lb and physically larger than the GB40 or GBX55
— No USB-C input or output, so recharging is slower than the GBX55
— At around $230 it is double the price of the GB40

WOLFBOX MegaVolt24

4.6

3 sources2 derived$178as of Sep 25

The MegaVolt24 is the high-capacity value play: 4000A and a 24000mAh pack, enough to jump almost anything and still keep your devices charged for days. TechGearLab made it an Editors' Choice and Pro Tool Reviews scored it 9.4/10. Size counts against it, as does a younger brand reputation, though the lifetime warranty takes the edge off the latter.

Strengths

— 24000mAh capacity charges phones multiple times
— 1200A peak current handles large engines
— USB-C 65W PD for laptops and devices

Watch-outs

— Heavier than slim competitor models
— Price higher than entry-level options
