Detailed Review

The GOOLOO GP4000 is a portable 12V lithium jump starter designed for drivers of cars, trucks, motorcycles, RVs, and more, capable of starting all gas engines and diesel up to 10.0L. It stands out as an all-in-one solution for dead battery emergencies, doubling as a massive-capacity power bank for charging phones and other devices during road trips or off-grid adventures.

In real-world tests from users, it delivers on its 4000A peak promise, firing up vehicles even with very low batteries via the boost button, and providing over 60 jumps per charge. Reviewers praise its quick action on gas and diesel engines, consistent performance across multiple uses without recharging, and ability to handle cold weather starts down to -4°F. The built-in LED flashlight with strobe and SOS modes proves invaluable at night.

Build quality shines with rugged plastic, rubber corners for drop protection, and sturdy metal clamps. Safety features like spark-less, reverse polarity, and anti-reverse protections give peace of mind, while the 15V 10A port powers tools like air compressors. Its slim profile fits easily in a glovebox or trunk.

Minor drawbacks include the need to connect detachable cables each time, which can be fiddly in the dark, and limitations with batteries that are completely sulfated from prolonged discharge. Repacking the EVA case takes some effort due to multiple compartments.

Overall, the GP4000 earns high marks for reliability and versatility, making it a top pick for anyone wanting a dependable, multi-purpose jump starter that exceeds expectations in emergencies.

Standout features include a 150PSI cordless compressor that inflates a Tesla Model 3 tire from 30 to 36 PSI in one minute, plus modes for SUVs, cars, bikes, balls, and custom settings. The 7-in-1 design adds emergency phone charging, an LED flashlight, digital pressure gauge, and bike/ball pump capabilities with five nozzles.
