| Criterion | GOOLOO GP4000 | HULKMAN Alpha85 |
|---|---|---|
| Scores | ||
| Overall | 4.3/5 | 3.9/5 |
| Spec strength | 4.5 4000 A and 24,000 mAh for 10 L engines, within a hair of the NOCO GBX155's 4250 A; GOOLOO does not publish Wh or USB-C wattage. | 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. |
| Build quality | 3.5 Rated -4°F to 140°F, but no IP rating or weight on the product page — NOCO publishes IP65 and 5.82 lb for the GBX155. | 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. |
| Fit & compatibility | 4.5 10.0 L gas and diesel coverage, the same ceiling as the GBX155 and far above the GB40's 6.0 L / 3.0 L. | 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. |
| Warranty & support | 4.5 Up to 30 months vs 12 on NOCO and 24 on HULKMAN. | 4.0 24 months vs 12 on every NOCO; GOOLOO goes to 30. |
| Value | 4.5 $189.99 list for 4000 A — about half the GBX155's $369.95 for a similar amp class. | 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. |
