| Criterion | HULKMAN Alpha85 | NOCO Boost X GBX155 |
|---|---|---|
| Scores | ||
| Overall | 3.9/5 | 3.9/5 |
| Spec strength | 4.0 2000 A / 74 Wh with a 15 V 150 W DC output and a 3.3-inch display; half the amps of the GP4000 but a far more complete spec sheet. | 5.0 4250 A and 99 Wh — the most amps and the biggest pack in this group; GOOLOO's GP4000 is rated 4000 A. |
| Build quality | 4.0 IP65 and a -5°F floor, similar to NOCO's -4°F; the Alpha85S variant adds pre-heat for -40°F if you live in the Upper Midwest. | 4.5 IP65, -4°F to 122°F operating range and a published charging range, which GOOLOO does not provide. |
| Fit & compatibility | 4.0 8.5 L gas / 6.0 L diesel beats the GB40 (6.0 L / 3.0 L) and covers most half-ton diesels, not 6.7 L HD trucks. | 4.0 Covers 8.0 L diesels (Power Stroke, Duramax, Cummins) but at 5.82 lb and 12 inches long it will not fit a glovebox like the 2.45 lb GB40. |
| Warranty & support | 4.0 24 months vs 12 on every NOCO; GOOLOO goes to 30. | 3.0 1 year on a $370 tool, vs 24 months on HULKMAN and up to 30 on GOOLOO. |
| Value | 3.5 $199.99 list is $10 more than the 4000 A GOOLOO GP4000, so you are paying for the display, DC port and published specs. | 3.0 $369.95 is nearly double the GOOLOO GP4000's $189.99 list for a similar 4000-amp-class rating. |
