The short answer

NOCO Boost Plus GB40 comes out ahead by a narrow margin (4.6 vs 4.5). The gap is mostly about everyday drivers of sedans, SUVs and small trucks who want a proven, glovebox-sized jump starter near $100 — read the strengths below before deciding.

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

NOCO Boost Plus GB40

4.6

4 sources2 derived

For most drivers the Boost Plus GB40 is the default answer: 1000A covers the engines sitting in an average driveway, the price stays near $100, and NOCO's safety engineering has the longest track record in the category. Move up to the GB70 or GBX55 only if you run a large diesel or want USB-C fast charging.

Strengths

— 1000A peak output starts virtually any passenger car, SUV or light truck (up to 6.0L gas / 3.0L diesel)
— Tiny 8-inch, 2.4 lb body fits a glovebox yet holds roughly 20 jumps per charge
— UltraSafe spark-proof clamps with reverse-polarity protection prevent the classic jump-start mishaps

Watch-outs

— Underpowered for large V8 diesels and big trucks that need the GB70 or GBX55
— Slow micro-USB recharge with no USB-C input on this generation
— Lithium cells need topping up every few months in storage to stay jump-ready
