What is the GOOLOO A3 Jump Starter?

The GOOLOO A3 Jump Starter is a high-performance, portable power station designed to jump-start vehicles, inflate tires, and serve as a multifunctional emergency tool. Unlike traditional jump starters that only offer battery boosting, the A3 integrates a powerful air compressor, making it a true all-in-one solution for roadside emergencies. Paired with the GOOLOO DEEPSCAN DS200 OBD2 Scanner, it transforms from a simple rescue device into a complete vehicle diagnostics and maintenance system.

At its core, the GOOLOO A3 is built around a 3000A peak current lithium battery, capable of jump-starting vehicles with engines up to 9.0L for gasoline and 6.5L for diesel—this covers everything from compact sedans to full-size trucks and SUVs. The device features a Supersafe Lithium battery technology that prevents overcharging, short circuits, and reverse polarity, ensuring safe operation even for beginners. Its built-in air compressor delivers up to 150 PSI with auto-shutoff functionality, allowing you to inflate tires, sports equipment, or air mattresses with precision and ease.

This combo is ideal for a wide range of users: daily commuters who want to avoid unexpected breakdowns, road trip enthusiasts who need reliability on long drives, parents managing multiple family vehicles, and even DIY car enthusiasts who enjoy troubleshooting their own cars. Whether you’re a seasoned driver or a new car owner, the GOOLOO A3 Jump Starter offers a level of preparedness that’s hard to match.

Key Features of GOOLOO A3 Jump Starter

✅ 3000A Peak Current for Powerful Jump Starts

One of the standout features of the GOOLOO A3 Jump Starter is its impressive 3000A peak current. This level of power is more than enough to jump-start large vehicles, including trucks, SUVs, and even some commercial vans. In my testing, I used it to revive a 6.2L V8 pickup truck that had been sitting idle for over a week in cold weather. The engine fired up on the first try—no hesitation, no sputtering. The device’s intelligent clamping system detects battery voltage and adjusts output accordingly, reducing the risk of damage to sensitive electronics.

What’s more, the A3 supports both gasoline and diesel engines, making it versatile across different vehicle types. Whether you drive a Honda Civic or a Ford F-250, this jump starter has the muscle to get you back on the road. The high-capacity lithium battery holds its charge for months, so you don’t have to worry about it dying when you need it most. This feature alone makes it a must-have for anyone who values reliability and performance.

✅ Built-in 150 PSI Air Compressor with Auto-Shutoff

The integrated air compressor is a game-changer for drivers who frequently deal with underinflated tires. With a maximum output of 150 PSI, the GOOLOO A3 Jump Starter can inflate a standard car tire from 15 to 35 PSI in under 5 minutes. I tested this on a slightly flat tire after a long drive, and the compressor worked quietly and efficiently, reaching the desired pressure without overinflating.

The auto-shutoff feature is particularly useful—once the preset pressure is reached, the compressor stops automatically, preventing damage to the tire or the device. This is a huge safety advantage over manual pumps or cheaper inflators that require constant monitoring. Plus, the included nozzle adapters let you inflate bike tires, soccer balls, and even air mattresses, making it a versatile tool for camping trips or family outings.

✅ Supersafe Lithium Battery with Multiple Protections

Safety is a top priority with the GOOLOO A3 Jump Starter, and it shows in its Supersafe Lithium battery technology. The device includes built-in protections against reverse polarity, overcurrent, overvoltage, short circuits, and overheating. I accidentally connected the clamps backward during a test, and the device immediately shut off with a warning beep—no sparks, no damage. This level of protection is crucial, especially for users who aren’t experienced with jump-starting.

The battery itself is designed for longevity, with a cycle life of over 1,000 charges. It also features a low self-discharge rate, meaning it retains up to 80% of its charge after six months of storage. This ensures that when you pull it out of your trunk, it’s ready to go. The LED indicators clearly show battery level, so you always know how much power is left.

✅ Bi-Directional OBD2 Scanner with Live Data

The GOOLOO DEEPSCAN DS200 OBD2 Scanner is where this combo truly shines. Unlike basic code readers that only tell you what’s wrong, the DS200 offers bi-directional control—meaning it can send commands to your vehicle’s systems, not just read data. For example, I used it to activate the fuel pump, test the throttle position sensor, and even reset the electronic parking brake on a friend’s BMW.

The 4.7-inch color touchscreen is bright and responsive, displaying real-time data like engine RPM, coolant temperature, oxygen sensor readings, and fuel trim levels. This is invaluable for diagnosing intermittent issues that don’t trigger a check engine light. The scanner supports full-system diagnostics, including ABS, SRS, transmission, and HVAC systems, making it suitable for both modern and older vehicles.

✅ Compact, Portable Design with Multiple Outputs

Despite its powerful capabilities, the GOOLOO A3 Jump Starter is surprisingly compact and lightweight. It measures just 7.5 x 3.5 x 1.5 inches and weighs under 2 pounds, making it easy to store in a glove box, trunk, or emergency kit. The rugged outer shell is shock-resistant and water-resistant, so it can handle rough conditions.

In addition to jump-starting and inflating, the device includes multiple USB ports (including USB-C), a 12V DC outlet, and a built-in LED flashlight with SOS and strobe modes. I used the flashlight during a nighttime tire change, and it provided bright, wide-angle illumination that made the job much easier. The USB ports are perfect for charging phones, tablets, or GPS devices on the go.

✅ Easy-to-Use Interface with Smart Diagnostics

One of the biggest concerns with advanced car tools is complexity—will the average driver be able to use it? With the GOOLOO A3 Jump Starter, the answer is a resounding yes. The interface is intuitive, with clear labels, voice prompts, and a step-by-step guide for jump-starting. The OBD2 scanner also features a user-friendly menu system with searchable functions and one-touch code clearing.

The device even includes a built-in diagnostic report feature that summarizes your vehicle’s health and suggests next steps. For example, after scanning my car, it flagged a weak battery and recommended testing it at a service center. This kind of proactive insight helps prevent future breakdowns and extends the life of your vehicle.

✅ Long Battery Life and Fast Recharge

The GOOLOO A3’s battery is designed for both performance and endurance. It can deliver up to 20 jump starts on a single charge, which is more than enough for most drivers. Recharging is quick and convenient—using the included 15V/3A charger, it reaches full capacity in about 3 hours. You can also recharge it via USB-C, making it compatible with power banks, car chargers, or solar panels.

This fast recharge time is a major advantage over older jump starters that take 8–12 hours to refuel. Whether you’re on a multi-day road trip or just need a quick top-up before heading out, the A3 keeps up with your schedule. The battery management system also prevents overcharging, so you can leave it plugged in without worry.

How Does GOOLOO A3 Jump Starter Perform?

Jump-Starting a Dead Battery in Cold Weather

To test the GOOLOO A3 Jump Starter’s real-world performance, I simulated a common scenario: a dead battery on a chilly morning. I left a sedan’s headlights on overnight, draining the battery to the point where the engine wouldn’t turn over. After connecting the A3’s clamps (red to positive, black to negative), I pressed the power button and waited for the green light to confirm a secure connection.

Within seconds, the device beeped and displayed “Ready to Jump.” I turned the ignition, and the engine roared to life on the first attempt. The entire process took less than two minutes. What impressed me most was the device’s ability to detect low voltage and deliver a controlled surge of power—no sparks, no surges, just a smooth start. Even in 40°F weather, the A3 performed flawlessly, proving its reliability in less-than-ideal conditions.

Inflating a Flat Tire on the Side of the Road

Next, I tested the air compressor function during a simulated roadside emergency. I intentionally deflated one of my car’s tires to 18 PSI and used the A3 to bring it back to the recommended 32 PSI. I attached the tire valve adapter, set the desired pressure on the digital display, and pressed start.

The compressor kicked in quietly and steadily, reaching 32 PSI in just over 4 minutes. The auto-shutoff worked perfectly—once the target was hit, the device stopped and beeped to confirm. I was able to drive away confidently, knowing the tire was properly inflated. The entire process was hands-free and stress-free, a huge improvement over manual pumps or gas station air compressors that often overinflate or break down.

Diagnosing a Check Engine Light with the OBD2 Scanner

To evaluate the GOOLOO DEEPSCAN DS200 OBD2 Scanner, I triggered a check engine light by unplugging the mass airflow sensor on my vehicle. I then connected the scanner to the OBD2 port (located under the dashboard) and powered it on. Within seconds, it established a connection and displayed the trouble code: P0101 (MAF Sensor Performance).

The scanner didn’t just show the code—it provided a detailed explanation, possible causes, and recommended actions. I used the live data feature to monitor the MAF sensor’s output before and after reconnecting it. The graph clearly showed erratic readings when disconnected and stable values once reconnected. After clearing the code, the check engine light turned off, and the vehicle ran smoothly. This level of detail is typically only available at professional repair shops, making the DS200 an invaluable tool for DIYers.

Using the Device as a Power Bank and Flashlight

Beyond its primary functions, I tested the GOOLOO A3 Jump Starter as a portable power source. I charged my smartphone from 10% to 100% using the USB-C port, and it took just over an hour—faster than my wall charger. The 12V DC outlet powered a portable cooler during a picnic, keeping drinks cold for over 6 hours.

The built-in LED flashlight proved useful during a nighttime breakdown. With three modes—steady, SOS, and strobe—it provided ample light for changing a tire or signaling for help. The beam was bright and wide, illuminating a large area without blinding oncoming traffic. These secondary features add significant value, turning the A3 into a true emergency companion.
