Being stuck with a dead car battery is more than just an inconvenience; it can throw your entire day off track, or worse, leave you stranded in a potentially unsafe situation. As a seasoned auto repair professional, I’ve seen countless drivers face this frustrating issue. That’s why I’m always on the lookout for reliable solutions that can empower drivers to handle these emergencies themselves. Recently, I put the GOOLOO A3 Portable Cordless 3,000A Battery-Operated Jump Starter with 150PSI Air Compressor to the test, and I must say, I’m genuinely impressed. This isn’t just another gadget; it’s a compact powerhouse designed to get you back on the road quickly and safely.
GOOLOO A3: Your 2-in-1 Roadside Assistance Hero
The GOOLOO A3 isn’t just a Portable Battery Jumper; it’s a versatile tool that combines jump-starting capability with a built-in air compressor. This dual functionality makes it an invaluable addition to any vehicle, offering peace of mind and practical solutions for common roadside emergencies.
Unleashing the Power of a 3,000A Portable Battery Jumper
The primary function of the GOOLOO A3, and arguably its most crucial, is its ability to jump-start your car. Boasting a peak current of 3,000A, this portable battery jumper packs enough punch to revive almost any 12V vehicle battery. From sedans to SUVs and even trucks with gasoline engines up to 8.0L and diesel engines up to 6.0L, the A3 is designed to deliver reliable jump starts.
What truly sets this portable battery jumper apart is its ease of use and safety features. The included detachable booster cables are straightforward to connect, and the unit itself clearly indicates whether you’ve hooked everything up correctly. A green light signals when it’s ready to boost, eliminating any guesswork and minimizing the risk of improper connections. Furthermore, the A3 incorporates a comprehensive Battery Management System (BMS) that provides protection against overheating, overcharging, overcurrent, undercurrent, and short circuits. This crucial safety net protects both the unit itself and your vehicle’s electrical system, giving you confidence during every jump start. Forget about relying on jump-start services or flagging down strangers; with the GOOLOO A3, you hold the power to resolve a dead battery situation independently.

More Than Just a Jump Starter: A Powerful 150PSI Air Compressor
Beyond its jump-starting prowess, the GOOLOO A3 also functions as a capable 150PSI air compressor. This integrated feature is incredibly convenient for maintaining proper tire pressure, which is essential for fuel efficiency, tire longevity, and safe driving. Whether you’re topping off tires before a road trip or dealing with a slow leak, the A3’s compressor is ready to assist.
The digital LCD display is a standout feature, providing clear and accurate pressure readings in various units (PSI, kPa, Bar). You can even preset your desired inflation pressure, and the compressor will automatically shut off once that pressure is reached. This prevents over-inflation and ensures accuracy. In my tests, inflating a standard truck tire from flat to 35 PSI took just 5-7 minutes, which is quite impressive for a portable unit. The A3 comes with a set of nozzles for inflating sports balls, inflatable toys, and more, further expanding its utility. The detachable metal air hose with a durable lever-head adds to the overall quality and ease of use.

Built to Last and Designed for Convenience
From the moment you unpack the GOOLOO A3, the build quality is evident. The heavy-duty ABS plastic casing feels robust and durable. The glossy red and black finish gives it a stylish and professional look. The compact design makes it easy to store in your trunk without taking up excessive space.
The bright LED light bar is a useful addition for nighttime emergencies. It provides adequate illumination for connecting jumper cables or inflating tires in low-light conditions. The SOS and strobe modes offer extra safety features if you need to signal for help. The internal USB-C rechargeable lithium-ion battery fully charges in about 4 hours and can provide up to 50 jump starts on a single charge, making it a reliable portable battery jumper for repeated use. It can also function as a USB power bank to charge your smartphones and other devices, adding another layer of practicality.

Real-World Performance and Minor Drawbacks
In practical use, the GOOLOO A3 performed admirably. Jump-starting a 5.7L V8 engine was effortless, demonstrating its powerful jump-starting capabilities. The air compressor worked efficiently, inflating tires quickly and accurately (though I did notice a slight discrepancy at very low pressures compared to a dedicated digital gauge, about 1.2 PSI at 8 PSI, which is minor for most practical purposes). The convenience of having both a portable battery jumper and air compressor in one unit cannot be overstated.
While the GOOLOO A3 excels in many areas, there are a couple of minor points to consider. The lack of rubber feet on the bottom means it can vibrate slightly when the compressor is running. Also, you can’t use the compressor while the unit is charging. These are minor inconveniences and don’t detract significantly from the overall value and performance. An onboard storage compartment for the included nozzles would also be a welcome addition for enhanced organization.
