The short answer

NOCO Boost Plus GB40 comes out ahead by a clear margin (4.6 vs 3.5). 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.

On paper, 2000A peak and 8.0L gas coverage for around $80 is hard to beat, and that makes the GP2000 the budget value pick. TechGearLab named it Best Buy, and testers confirmed strong real-world boosts on smaller engines. Owner reliability reports are uneven and the reserve is weaker, so treat it 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, per CarBatteryNerd
  • — Handled eight consecutive boosts on a 2.5L engine before recharging, per TechGearLab
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

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
