The short answer

NOCO Boost HD GB70 comes out ahead by a narrow margin (4.3 vs 4.1). NOCO Boost HD GB70 is best for: owners of large gas trucks, V8s and diesel engines who want maximum cranking reserve and rugged cables. Read the strengths below before deciding.

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
  • — Up to 40 jumps per charge so it rarely needs a top-up in the trunk
  • — Over-engineered 8AWG clamp cables built for repeated heavy-duty outdoor use
  • — Smart sensing delivers only the current the connected battery needs, protecting electronics
Watch-outs
  • — Overkill for someone who only jumps a four-cylinder commuter car

Ranked #2 in Best Portable Jump Starters

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
