GOOLOO A3 Portable Jump Starter with Air Compressor — 3000A Boost, 150 PSI Inflator

GOOLOO A3 is a compact 7-in-1 emergency power unit that jump-starts 12V vehicles up to 9.0L gas/6.5L diesel and doubles as a high-pressure cordless air compressor and power bank.

The GOOLOO A3 combines a 3000A jump starter, a smart tire inflator, a rechargeable battery bank, and a bright LED work light into one rugged package designed for roadside emergencies and routine maintenance. Built with GOOLOO JUMPCORE and TOOLCORE technologies, the unit delivers rapid starts even from extremely low battery voltages, while the integrated air pump supports multiple inflation modes and precise pressure control. Its temperature-hardy construction and multiple electronic protections make it suited to year-round use.

How quickly will the A3 restart my car and what engines can it handle?

The A3 supplies a 3000-amp surge designed to restart most dead 12V batteries, including larger engines. Use the BOOST function to force a start when battery voltage is very low; the heavy-duty clamps and high-output cells provide reliable cranking power.

• Supports up to 9.0L gasoline and 6.5L diesel engines
• 3000A peak current for fast engine cranking
• BOOST button for ultra-low-voltage situations
• Over 1000 charge cycles for long-term dependability

What inflation capabilities does the built-in air compressor offer?

The A3’s integrated compressor reaches up to 150 PSI with an airflow of 35 L/min and five inflation modes for vehicles, bikes, balls and custom presets. A clear LED screen shows live pressure and automatically stops when your selected pressure is reached, making inflation quick and hands-free.

• Five presets: SUV, car, bike, ball and customizable mode
• Includes five nozzle types for versatile attachments
• Inflates Tesla Model 3/Y from 30 to 36 PSI in about one minute
• Up to 45 minutes continuous cordless inflation on a full charge

What safety features and device charging options are included?

Safety is managed by GOOLOO SUPERSAFE protections and a built-in battery management system (BMS) that guards against common electrical faults. The A3 also acts as a USB power bank for phones and tablets, making it useful beyond vehicle emergencies.

• Ten protections: short-circuit, overcurrent, reverse-connection, overheating, overcharge, and more
• USB output for charging smartphones, tablets and accessories
• Smart LED flashlight with multiple modes for roadside visibility
• Durable performance across -4°F to 140°F operating temperatures

How do I maintain and store the A3 for best performance?

To keep the A3 ready, fully charge it before first use and recharge at least once every three months when stored. Observe the recommended temperature windows while charging and storing to preserve battery life and reliability.

• Charge fully before first use; recharge every 3 months for storage
• Operating/storage range: -4°F to 140°F; charge between 14°F and 113°F
• Avoid long exposure to high heat, moisture, or direct sun
• Includes a carrying bag and all accessory nozzles for neat storage

Who is this for? The GOOLOO A3 is built for drivers, tradespeople, cyclists, and families who want an all-in-one roadside tool: a rugged jump starter for larger engines, a fast and accurate cordless inflator, and a phone-charging power bank. If you need a compact emergency kit that handles tire care, device charging, and reliable jump starts in varied climates, the A3 is a practical addition to your trunk, garage, or workshop.
