GOOLOO A3 3000A Portable Jump Starter with 150PSI Auto-Shutoff Air Compressor — 12V Lithium Booster for up to 9.0L Gas / 6.5L Dies

GOOLOO A3 is a 7-in-1 portable 3000A lithium jump starter with a built-in 150PSI auto-shutoff air compressor, designed to restart 12V vehicles up to 9.0L gas / 6.5L diesel and inflate tires on the go.

The GOOLOO A3 combines a high-capacity jump pack, smart tire pump, USB power bank and flashlight into a single rugged unit for roadside readiness. Built for durability and frequent use, the A3 supports over 1000 charge cycles and runs reliably between -4°F and 140°F. Its integrated battery management system protects your vehicle and device with multiple safety layers while the compressor and digital gauge simplify inflation tasks.

How quickly can the A3 get my car running after a dead battery?

The A3 delivers 3000 peak amps and a BOOST button for forced starts when battery voltage is very low, enabling fast restarts for 12V systems. It’s rated for engines up to 9.0L gas or 6.5L diesel and includes jumper cables designed for safe connections.

• 3000A peak output for instant cranking power
• Supports 9.0L gas / 6.5L diesel engines
• BOOST mode for extremely low-voltage batteries
• Smart jumper cable with reverse-connection protection

What can the built-in air compressor do for me?

The integrated pump reaches up to 150 PSI with an airflow of 35 L/min and an automatic shutoff when target pressure is detected. It comes with five inflation modes and five nozzle attachments to handle cars, SUVs, bikes, balls and custom pressure requirements.

• 150 PSI maximum and 35 L/min airflow for fast inflation
• Five preset modes (suv, car, bike, ball, custom) for convenience
• Inflates a Tesla Model 3/Y tire from 30 to 36 PSI in about one minute
• Auto-shutoff and digital gauge prevent overinflation

Which extra features make the A3 useful beyond jump-starting?

Beyond its primary functions, the A3 serves as a portable power bank, LED flashlight and digital pressure gauge, making it a multi-use roadside tool. A single full charge supports a long inflation runtime and multiple device charges, with clear status readouts via a bright screen.

• Charges phones and tablets via USB ports
• LED flashlight for nighttime emergencies and locations
• Inflation capacity: up to 135 balls, 50 bike tires, 35 motorcycle tires, or 8 car tires
• Bright display readable in sunlight with tire pressure detection

How safe and durable is the GOOLOO A3 for repeated roadside use?

The A3 includes an advanced battery management system (BMS) offering ten protective functions to reduce risk during use. It’s rated for extreme temperatures and more than 1000 charge cycles, with recommended usage limits to protect the compressor and jump cell.

• BMS protections: short circuit, overcurrent, reverse connection, overheating, overcharge and more
• Operational range from -4°F to 140°F for year-round reliability
• Over 1000 charge cycles for long-term durability
• Usage guidance: max 3 consecutive jump starts, cooling breaks for continuous pump use

Who is this for: The GOOLOO A3 is aimed at drivers, fleet operators, cyclists, and outdoor enthusiasts who want a single compact tool for emergency starts, tire inflation and device charging. It suits anyone who values fast, reliable roadside assistance without needing multiple gadgets — particularly owners of larger gas or diesel vehicles, EV owners who need tire maintenance gear, and travelers who prefer a rugged, all-in-one solution.

Package contents include the A3 unit, smart jumper cable, USB-A to USB-C cable, carrying bag, pump tube, five air nozzles and a user manual. GOOLOO backs the product with an 18-month warranty and clear operational notes: avoid more than three consecutive jump starts; allow two minutes between attempts; and pause inflation if the compressor overheats.
