NOCO Boost X GBX55 vs WOLFBOX MegaVolt24

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 X GBX55 and WOLFBOX MegaVolt24 score essentially the same (4.5 vs 4.5). Pick the one whose trade-offs match your priorities — the strengths and watch-outs below are where they actually differ.

NOCO Boost X GBX55
Ranked #4 in Best Portable Jump Starters
NOCO Boost X GBX55
$166.2as of Jun 7

The Boost X GBX55 is NOCO's USB-C generation: 1750A handles most large gas and mid-size diesel engines, and the 60W USB-C port makes it the most charging-versatile NOCO unit here, topping off laptops and reaching jump-ready in five minutes. It is the pick for road-trippers who value fast recharge and device power over raw peak amps.

Strengths
  • — 1750A peak starts up to 7.5L gas and 5.0L diesel engines
  • — 60W USB-C Power Delivery charges in and out, and reaches jump-ready in five minutes of charge
  • — Full recharge in just 1.2 hours, far faster than micro-USB NOCO units
Watch-outs
  • — Mixed user reports of battery longevity and a few early failures
  • — Costs about the same as the more powerful WOLFBOX MegaVolt24
  • — Clamp cable length is on the shorter side for some engine bays

WOLFBOX MegaVolt24
Ranked #3 in Best Portable Jump Starters
WOLFBOX MegaVolt24
$129.99as of Jun 7

The MegaVolt24 is the high-capacity value play: 4000A and a 24000mAh pack mean it can jump almost anything and still charge your devices for days. TechGearLab made it an Editors' Choice and Pro Tool Reviews scored it 9.4/10. The downsides are size and a younger brand reputation, but the lifetime warranty offsets the latter.

Strengths
  • — Massive 4000A peak output starts engines up to 10L gas and 10L diesel
  • — Large 24000mAh / 88.8Wh battery runs many jumps and acts as a serious power bank
  • — 65W USB-C Power Delivery recharges fast and tops off laptops and phones quickly
Watch-outs
  • — Larger and heavier than compact NOCO units, less glovebox-friendly
  • — 4000A is far more than most passenger cars will ever need
  • — Newer brand with a shorter long-term reliability track record than NOCO

How they stack up

NOCO Boost X GBX55

The charging-versatility pick. Its 60W USB-C recharge and device-power output beat the micro-USB NOCO Boost Plus GB40 and NOCO Boost HD GB70, and match the WOLFBOX MegaVolt24, while its 1750A peak sits between the GB40 and GB70 and above the GOOLOO GP2000 on engine range.

WOLFBOX MegaVolt24

The power-and-capacity king of this group. Its peak output and battery pack dwarf the NOCO Boost HD GB70, the NOCO Boost X GBX55, the NOCO Boost Plus GB40 and the GOOLOO GP2000, and only the GBX55 matches its USB-C fast charging convenience.
