GOOLOO GP2000 vs NOCO Boost Plus GB40

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

NOCO Boost Plus GB40 comes out ahead by a clear margin (4.3 vs 4.7). 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 #5 in Best Portable Jump Starters

GOOLOO GP2000

4.3

$49.99as of Jun 7

The GP2000 is the budget value pick: 2000A peak and 8.0L gas coverage for around $80 is hard to beat on paper. TechGearLab named it Best Buy and testers confirmed strong real-world boosts on smaller engines. The catch is uneven owner reliability reports and a weaker reserve, so it is best as an affordable backup rather than a heavy-duty daily tool.

Strengths

— 2000A peak output for the price of most 1000A units
— Rated for up to 8.0L gas and 6.0L diesel engines despite the budget cost
— Handled eight consecutive boosts on a 2.5L engine in testing before recharging

Watch-outs

— Less effective on the largest truck batteries than its amp rating suggests
— Polarized owner reviews, with some early-failure and charging complaints
— Shorter warranty and less proven QC than NOCO

Higher ratedRanked #1 in Best Portable Jump Starters

NOCO Boost Plus GB40

4.7

$99.95as of Jun 7

The Boost Plus GB40 is the default recommendation for most drivers: 1000A is plenty for the engines in the average driveway, the price stays near $100, and NOCO's safety engineering is the most proven in the category. Step 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

How they stack up

GOOLOO GP2000

The budget choice. It undercuts the NOCO Boost Plus GB40 on price while matching the 2000A peak of the NOCO Boost HD GB70 on paper, though it trails the GB70, the NOCO Boost X GBX55 and the WOLFBOX MegaVolt24 on build quality and reliability track record.

NOCO Boost Plus GB40

The most compact and affordable pick here. It is outpowered by the 2000A NOCO Boost HD GB70, the 1750A USB-C NOCO Boost X GBX55, and the 4000A WOLFBOX MegaVolt24, but it costs less than all of them and covers the engines most drivers actually own. Only the GOOLOO GP2000 undercuts it on price.
