Read the full review summary
The GP4000 pairs a 4000A peak output with support for gasoline and diesel engines up to 10.0L.
It is aimed at drivers who want a compact jump pack for a mix of 12V vehicles, from passenger cars and motorcycles to trucks and RVs.
Its dual USB outputs, USB-C port, flashlight, and rugged shell give the unit jobs beyond starting a vehicle.
The tradeoff is that this is still a lithium battery device that needs periodic upkeep: GOOLOO recommends charging it every 2–3 months after extended idle periods, and a wall charger is not included.

GOOLOO GP4000 Review Analysis
Starting capacity and vehicle fit
The 4000A rating and stated engine limits make this a broad-use jump pack for many cars and work vehicles.
The BOOST button is a practical detail for low-voltage situations, although drivers should follow the included cable instructions and vehicle guidance when attempting a start.
Useful power beyond the jump
Dual USB ports and USB-C can make the pack useful for charging electronics on a trip, and the flashlight adds a simple lighting function for nighttime roadside work.
This combination favors drivers who want one stored device to cover several modest emergency needs.
Storage and maintenance
The hardened-plastic body, rubber corners, compact design, and EVA case are aimed at vehicle storage, while the upkeep reminder matters for equipment that may sit unused between emergencies. Owners should make periodic charging part of their vehicle-kit routine.
