GOOLOO A3 12V 3000A Portable Jump Starter with Air Compressor – 7-in-1, 150 PSI, USB Power Bank

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

Compact but rugged, the GOOLOO A3 combines jump-start capability, a cordless high‑pressure inflator, USB power delivery, and an LED work light into a single handheld unit. It uses GOOLOO JUMPCORE and TOOLCORE technologies for reliable power delivery and SUPERSAFE electronics to protect both the unit and the vehicle. Built for frequent use, the battery supports over 1000 charge cycles and operates across a wide temperature range so you can trust it in roadside emergencies or for recreational trips.

How does the A3 restart a dead battery and what vehicles can it handle?

The A3 delivers a 3000A peak current with a BOOST button to safely force a restart from very low voltages. It's engineered for 12V systems and covers a broad range of engines, from compact cars to larger gas and diesel engines. GOOLOO’s protections prevent damage from incorrect connections or electrical faults.

• Supports gasoline engines up to 9.0L and diesel engines up to 6.5L
• BOOST mode activates when battery voltage is extremely low
• Includes smart jumper cable with reverse-connection and short-circuit protection
• Over 1000+ charge cycles for long-term reliability

What can the built-in air compressor do and how fast is it?

The integrated pump reaches a maximum pressure of 150 PSI and an airflow of 35 L/min, with five preset modes for tires, bikes, and balls. It’s fast enough to top off common EV and passenger-car tires quickly and runs cordless for extended sessions when fully charged. A clear LED display and auto shut-off make inflation simple and accurate.

• Five inflation modes: SUV, car, bike, ball, and customizable
• Inflates a Tesla Model 3/Y from 30 to 36 PSI in about one minute
• Up to 45 minutes of continuous cordless inflation on a full charge
• Comes with five nozzle adapters for versatile use

What other functions does the A3 offer beyond jumping and inflating?

Besides emergency starting and tire inflation, the A3 serves as a portable power bank, flashlight, and digital pressure gauge. It supports USB device charging and delivers reliable light for nighttime repairs. These added tools make the A3 a practical companion for road trips, bike rides, and outdoor activities.

• USB output for charging phones, tablets, and accessories
• LED flashlight for roadside visibility and signaling
• Digital pressure readout with selectable units (BAR/PSI/KPA)
• Can inflate dozens of items per charge (balls, bike tires, etc.)

How safe and durable is the device for regular use?

GOOLOO built the A3 with SUPERSAFE protections and an advanced battery management system to avoid common electrical hazards. It operates across a wide temperature span and includes safeguards like overcurrent, overcharge, and overheating protection. Follow the recommended charging and storage guidelines to preserve performance and warranty coverage.
