| Criterion | HULKMAN Alpha85 | NOCO Boost X GBX45 |
|---|---|---|
| Scores | ||
| Overall | 3.9/5 | 3.7/5 |
| 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. | 3.5 1250 A and 31 Wh with real 60 W USB-C PD — a step up from the GB40's 1000 A / 24 Wh, still well under HULKMAN's 2000 A / 74 Wh. |
| 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 and 2.16 lb — lighter than the GB40 (2.45 lb) with more output. |
| 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 6.5 L gas / 4.0 L diesel adds small diesels the GB40 (3.0 L) cannot cover; big diesel pickups still need the GBX155. |
| Warranty & support | 4.0 24 months vs 12 on every NOCO; GOOLOO goes to 30. | 3.0 1 year, same as the GB40, vs 24 months on HULKMAN. |
| 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. | 3.5 $124.95, $25 over the GB40 for 25% more amps and 60 W USB-C; the HULKMAN Alpha85 lists at $199.99 for 2000 A. |
