3000A Jump-Starting Power
The A3 delivers up to 3000A peak current and is designed for 12V vehicles with gas engines up to 9.0 liters or diesel engines up to 6.5 liters. Its BOOST function is intended to help when a vehicle battery is at an extremely low voltage.
150 PSI Air Compressor
The integrated compressor reaches up to 150 PSI and delivers up to 35 L/min airflow. GOOLOO says it can raise a tire from 30 to 36 PSI in about one minute under its stated test conditions. The automatic shutoff lets you set a target pressure and stop inflation when that pressure is reached.
Five Smart Inflation Modes
The digital inflator provides preset modes for common tasks such as cars, SUVs, bicycles and balls, plus a custom mode. The display shows pressure information and supports PSI, BAR and KPA units.
Roadside Emergency Features
Because the A3 combines a jump starter, tire inflator, power bank and emergency light, it can replace several individual items in a basic roadside kit. The built-in light includes steady, flashing and SOS modes, which can be useful during nighttime roadside problems.
Safety and Operating Range
GOOLOO lists 10 safety protections, including safeguards against problems such as reverse connection, short circuits and overcurrent. The company rates the A3 for operation from -4°F to 140°F. Always follow the included instructions when jump-starting a vehicle.
