The buying factors
GOOLOO GP4000 Scorecard
Editorial scores reflect listed features and buyer fit; they are not laboratory measurements or customer ratings.
Engine range
Support for gasoline and diesel engines up to 10.0L gives the pack a broad stated fit across many 12V vehicles.
Emergency boost function
A dedicated BOOST button is useful when a vehicle battery voltage is extremely low, though safe connection and use still depend on following the instructions.
Device charging
Two USB outputs, including one fast-charging port, plus USB Type-C make the pack useful for charging compatible personal electronics.
Protection features
Ten built-in protection types and smart jumper cables address common misuse concerns, although they do not replace careful setup.
Portability and storage
A compact design and included EVA case make it easier to keep the booster and its accessories together in a vehicle.
Cold-weather operating range
Its operating range reaches down to -4°F, which may suit drivers preparing for cold conditions; check that the full range fits the temperatures you expect.

Who Should Buy GOOLOO GP4000?
Good fit
Buy the GP4000 if you want a portable jump starter for a compatible 12V vehicle and value coverage for engines up to 10.0L.
The BOOST function is relevant if you want a dedicated control for extremely low battery voltage situations.
It also makes sense for drivers who want emergency device charging, since it has USB-A style outputs and USB Type-C, along with cables and a storage case in the box.
Who should skip it
Skip it if you need a tire inflator integrated into the same device. The GP4000 is presented as a jump starter and device charger, with no tire-inflation function identified in its features.
GOOLOO GP4000: Practical Emergency Power for Drivers
Jump-starting scope
The GP4000 is aimed at 12V vehicles and lists compatibility across cars, motorcycles, trucks, RVs, ATVs, and other vehicle types.
Its gasoline and diesel engine support up to 10.0L makes engine size an important fit check before purchase, especially for commercial or recreational vehicles.
Boost and safe setup
The BOOST button addresses an extremely low-voltage battery scenario, while built-in protection and smart jumper cables add safeguards for setup. Treat these as helpful design features, not a reason to skip the included instructions or vehicle-specific precautions.
Power beyond the starter
USB outputs let the pack serve as a backup charger for compatible phones, tablets, cameras, and GPS devices.
The full-charge jump-start figure is over 60 starts for most vehicles, but actual readiness still depends on keeping the unit charged during storage.
Storage and weather planning
The compact design, supplied case, and built-in flashlight make it practical to keep in a vehicle emergency kit.
The jump starter's operating range runs from -4°F to 140°F, and the wall charger is not included, so plan how you will recharge the pack.
