Overview
The Gooloo A3 pairs a 3000A 12V jump starter with a 150 PSI tire inflator, LED flashlight and USB power bank in one trunk-sized case. It targets drivers who want a single tool for a dead battery, a low tire and a dead phone.
Gooloo brands this as a 7-in-1 unit, but the two functions that matter are the jump starter rated to 9.0L gas and 6.5L diesel engines and the 35L/min air compressor with five nozzle types. The boost button is a manual step, not automatic, which a couple of owners flagged as an extra thing to remember mid-emergency. It is built around a battery management system with ten separate protections, which matters for a device that sits in a hot trunk for months between uses.
- 3000A jump start rated for engines to 9.0L gas or 6.5L diesel
- 150 PSI air compressor with 5 nozzles and auto shutoff
- Built-in LED flashlight and USB power bank
- Battery management system with 10 protection circuits
Who it's for
Drivers who keep one emergency box in the trunk for both a dead battery and low tires, including SUV and light truck owners up to a 6.5L diesel engine. Less suited to anyone who mainly needs a dedicated shop compressor for high-volume inflation.
What buyers say
From Amazon customer reviews.
Owners describe it cranking cars that a separately charged jump pack could not restart, including one case where a Duralast charger failed after 30 minutes and this unit started the car almost immediately. Multiple reviewers use it mainly for the tire inflator, praising the automatic pressure readout and quick fill speed. One buyer's second unit developed an overheating defect, though they noted the manufacturer's customer service resolved it well. The recurring complaints are a loud compressor motor, a tight charging plug and having to press the boost button by hand rather than it firing automatically.
