| Overall | 3.9/5 | 3.6/5 |
| 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. | 3.0 1000 A and 24 Wh vs 2000 A / 74 Wh on the HULKMAN Alpha85 and 4000 A on the GOOLOO GP4000; no USB-C Power Delivery. |

| 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 6.0 L gas / 3.0 L diesel covers most cars and half-ton gas trucks, but not diesel pickups (GBX155: 8.0 L diesel). |
| Warranty & support | 4.0 24 months vs 12 on every NOCO; GOOLOO goes to 30. | 3.0 1 year vs 24 months on HULKMAN and up to 30 months 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. | 3.5 $99.95 for 1000 A; the GOOLOO GP4000 lists at $189.99 for 4000 A, so you pay for NOCO's safety record and build, not amps. |
