GOOLOO A3 3000A Portable Jump Starter with 150PSI Air Compressor — Yellow, 7-in-1 Car Battery Booster & Tire Inflator

GOOLOO A3 is a compact 7-in-1 roadside power and inflation tool that combines a 3000A 12V lithium jump starter with a 150 PSI auto-shutoff tire inflator and multiple charging functions.

Built for drivers who want a single device to restart large gasoline or diesel engines, inflate tires, and charge electronics, the GOOLOO A3 pairs high cranking power with a smart pump and safety-focused battery management. Its rugged build and multiple adapters make it useful for cars, bikes, motorcycles, sports equipment, and emergency charging, while the bright display and automatic shutoff simplify use in low-light or urgent situations.

How powerful is this jump starter and which engines can it handle?

The A3 delivers up to 3000 peak amps and is engineered to revive a 12V dead battery quickly. It supports large engines and repeated use thanks to a durable lithium pack tested for over 1000 charge cycles and wide temperature tolerance.

• 3000A peak for instant starting assistance.
• Suitable for gasoline engines up to 9.0L and diesel up to 6.5L.
• BOOST mode to force-start extremely low-voltage batteries.
• Operates between -4°F and 140°F for year-round reliability.

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

The integrated inflator supports a maximum pressure of 150 PSI and features an automatic shutoff tied to the digital pressure reading. It pumps quickly for common tire sizes and offers preset modes to simplify inflation for different vehicles and objects.

• 150 PSI maximum pressure with 35 L/min airflow.
• Inflates a 205/55 R14 car tire from 25 to 36 PSI in about one minute.
• Five inflation modes: SUV, car, bike, ball, and a customizable setting.
• Auto-shutoff and a clear LED display for safe, accurate pressure control.

What extra tools and protections are included with the A3?

Besides jump-starting and inflating, the A3 functions as a power bank, flashlight, and digital pressure gauge with several nozzle adapters for varied uses. It also incorporates a multi-protection battery management system to protect the device and connected equipment.

• 7-in-1 utility: jump starter, air pump, device charger, flashlight, bike/ball pump, and digital gauge.
• Charges phones and tablets via USB ports; supports numerous inflation cycles (e.g., up to 8 car tires per full charge).
• BMS offers overcurrent, short-circuit, reverse-connection, overcharge, and overheating protections.
• Includes smart jumper cable, pump hose, five nozzles, USB-C cable, and carrying bag.

How easy is the A3 to use during an emergency or on a trip?

The A3 is designed for straightforward operation: a bright, sunlight-readable screen, preset inflation modes, and one-button BOOST for tough starts. Its carry bag and compact footprint make it convenient to store in a trunk or garage.

• Large, ultra-bright display remains readable in sunlight or at night.
• One-touch BOOST for low-voltage jump starts and auto-stop for inflation.
• Portable form factor with included carrying bag for travel and roadside storage.
• Rated for extended use: up to 45 minutes continuous inflation on a full charge.

Who is this for: The GOOLOO A3 is aimed at drivers, fleet operators, and outdoor enthusiasts who need a dependable, portable solution for jump-starting larger engines, inflating tires and sports gear, and charging devices in emergencies. It suits anyone seeking an all-in-one roadside kit with safety protections and quick, easy operation rather than carrying separate tools.
