Our verdict
Buy it if you own a large diesel truck between 7 and 10 liters. For a car or half-ton truck, a smaller IP65-rated starter is the better tool.
Pros and cons
Pros

- Rated to work from -4°F to 140°F
- Up to 30 months of warranty
Cons
- No water or dust rating; GOOLOO lists IP65 only for its GT4000
- Weight and dimensions are not published

Who it suits
Owners of heavy-duty diesel pickups, vans and equipment up to 10.0 L. GOOLOO rates the GP4000 for 12 V gasoline and diesel engines up to 10.0 L, which goes past the 7.0 L diesel rating of the NOCO GB150. See GP4000 vs GB150.
Who should skip it
Anyone who keeps a starter where it can get wet: GOOLOO lists no IP rating for the GP4000. Drivers of ordinary cars do not need 4,000 amps; a smaller starter such as the NOCO GBX45 is easier to carry.
What we could not confirm
GOOLOO's pages do not give the GP4000's weight, dimensions, flashlight brightness or per-port USB wattage. The 88.8 Wh battery figure comes from GOOLOO's FAQ. GOOLOO's pages also disagree on the number of protection features (eight or ten), so we do not quote a number.
