NOCO Boost HD GB70 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 HD GB70 comes out ahead by a narrow margin (4.6 vs 4.5). The gap is mostly about owners of large gas trucks, V8s and diesel engines who want maximum cranking reserve and rugged cables — read the strengths below before deciding.

Higher ratedRanked #2 in Best Portable Jump Starters

NOCO Boost HD GB70

4.6

$199.95as of Jun 7

The Boost HD GB70 is the pick for big-engine and diesel owners. 2000A reliably cranks 8.0L gas and 6.0L diesel motors, the 40-jump reserve means you can forget about it for months, and the rugged cables shrug off shop and trail abuse. The trade-offs are weight, bulk and a dated micro-USB charging port.

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

Ranked #3 in Best Portable Jump Starters

WOLFBOX MegaVolt24

4.5

$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 HD GB70

The big-engine specialist. It doubles the 1000A NOCO Boost Plus GB40 on cranking reserve and matches the on-paper peak of the GOOLOO GP2000 while far exceeding its reliability, and it outlasts the 1750A NOCO Boost X GBX55 on jumps per charge, though the GBX55 charges faster over USB-C and the WOLFBOX MegaVolt24 still beats it on raw 4000A peak.

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.
