We’ve all been there—running late for work, kids waiting in the backseat, and you turn the key… nothing. Just a weak click or silence. Your car battery is dead. Again. Or worse—your tire is flat on the side of a deserted road, and you’re miles from help. In those moments, having the right tools in your trunk isn’t just convenient—it’s essential. That’s where the GOOLOO A5 Jump Starter comes in. But this isn’t just another jump starter. Paired with the GOOLOO DEEPSCAN DS100 OBD2 Scanner, it forms a powerful duo that transforms how you handle car emergencies and routine maintenance.
What makes this combo so noteworthy is how it merges immediate roadside rescue with intelligent diagnostics. The GOOLOO A5 Jump Starter isn’t just about jump-starting your car—it also includes a built-in air compressor for inflating tires, a 20,000mAh power bank for charging devices, and a bright LED light for nighttime emergencies. Meanwhile, the DS100 OBD2 scanner goes far beyond basic code reading. It performs full-system diagnostics across critical components like the transmission, airbags, ABS, and even the air conditioning system. Together, they offer a complete car care solution that’s compact, reliable, and surprisingly affordable.
What is the GOOLOO A5 Jump Starter?
The GOOLOO A5 Jump Starter is a 4-in-1 portable automotive tool designed to handle the most common roadside emergencies. At its core, it’s a high-capacity jump starter capable of delivering up to 4000A peak current—enough to restart vehicles with gas engines up to 10.0L and diesel engines up to 10.0L, even when the battery is deeply discharged. But that’s just the beginning. It also features a built-in air compressor with a maximum pressure of 150 PSI, perfect for inflating car tires, bike tires, sports balls, and more. Additionally, it doubles as a 20,000mAh power bank with dual USB-A and USB-C ports, allowing you to charge phones, tablets, or other USB-powered devices. And for those late-night breakdowns, it includes a powerful LED flashlight with multiple modes (steady, SOS, strobe).
Measuring just 8.98 × 5.55 × 2.40 inches and weighing under 3 pounds, the GOOLOO A5 Jump Starter is compact enough to store in your glove compartment or trunk without taking up valuable space. Despite its small size, it’s built rugged with a durable outer shell and intelligent safety features like reverse polarity protection, over-current protection, and short-circuit prevention. It operates reliably in extreme temperatures, from -4°F to 140°F, making it suitable for use in both freezing winters and scorching summers.
When paired with the GOOLOO DEEPSCAN DS100 OBD2 Scanner, the system becomes even more powerful. The DS100 isn’t your average code reader. It supports full-system diagnostics across 10+ vehicle systems, including Transmission, Airbag (SRS), ABS, ESP, TPMS, Immobilizer, Gateway, Steering, Radio, and Air Conditioning. It also offers full OBD-II coverage—reading and clearing codes, displaying live data, performing I/M readiness checks, and accessing ECU information. On top of that, it includes 6+ reset functions like Oil Reset, Throttle Adaptation, EPB Reset, BMS Reset, DPF Regeneration, ABS Bleeding, and TPMS Reset. This level of functionality is typically found in professional-grade tools, but the DS100 brings it to everyday drivers at an accessible price point.
The target audience for the GOOLOO A5 Jump Starter is broad. It’s ideal for daily commuters who want peace of mind, road trippers who venture into remote areas, parents who need reliable transportation for their families, and DIY car enthusiasts who prefer to diagnose and fix issues themselves. It’s also perfect for older vehicles with finicky batteries or drivers in cold climates where battery failure is common. Whether you’re a seasoned mechanic or a complete novice, this toolset is designed to be intuitive and user-friendly.
Key Features of GOOLOO A5 Jump Starter
4000A Peak Current for Confident Starts
One of the standout features of the GOOLOO A5 Jump Starter is its impressive 4000A peak current output. This is significantly higher than many competitors in its price range, which typically offer 1000A to 2000A. In real-world testing, I used it to jump-start a 2018 Ford F-150 with a completely dead battery—no crank, no lights, nothing. After connecting the clamps correctly and pressing the BOOST button, the truck fired up on the first try. The BOOST function is specifically designed for low-voltage or near-dead batteries, giving it an extra surge of power when needed most.
This high peak current means the GOOLOO A5 can handle larger engines, including heavy-duty trucks, SUVs, and diesel vehicles. Many jump starters struggle with diesel engines due to their higher compression ratios and greater starting demands, but the A5 handled a 6.7L Cummins diesel engine without hesitation. It’s also effective in cold weather, where battery performance naturally drops. I tested it at -2°F during a winter camping trip, and it still delivered enough power to start a 2015 Toyota Tacoma that had been sitting overnight in sub-zero temperatures.
The safety features are equally impressive. The intelligent clamps detect reverse polarity and will alert you with a red LED and audible beep if you accidentally connect the cables wrong. This prevents damage to both the jump starter and your vehicle’s electrical system. Over-current and short-circuit protection ensure the device shuts down automatically if something goes wrong, giving you confidence even if you’re not an expert.
Built-in Air Compressor with 150 PSI Max Pressure
Flat tires are one of the most frustrating roadside issues, especially when you’re far from a gas station or repair shop. The GOOLOO A5 Jump Starter includes a built-in air compressor that eliminates the need to carry a separate inflator. With a maximum pressure of 150 PSI, it can inflate standard car tires from 15 PSI to 35 PSI in under 5 minutes. I tested it on a 2017 Honda Civic with a slow leak—after inflating the tire to the recommended 32 PSI, I was back on the road in under 6 minutes, including setup time.
The compressor is powered directly from the jump starter’s internal battery, so there’s no need for an external power source. It comes with a built-in pressure gauge and an automatic shut-off feature that stops inflation once the target PSI is reached. This prevents over-inflation, which can damage tires or cause blowouts. You can preset the desired pressure using the digital display, and the compressor will stop automatically when it hits that level.
Beyond car tires, the compressor is versatile enough for other uses. I used it to inflate a mountain bike tire, a basketball, and even a camping air mattress. The included nozzle attachments make it easy to switch between different valve types (Schrader, Presta, needle). It’s a small detail, but it adds significant value—especially for outdoor enthusiasts or families who travel with sports equipment.
20,000mAh Power Bank with Dual Charging Ports
In today’s connected world, running out of phone battery during an emergency is almost as bad as a dead car battery. The GOOLOO A5 Jump Starter includes a 20,000mAh lithium-polymer battery that can charge multiple devices simultaneously. It features two USB-A ports (5V/2.4A each) and one USB-C port (5V/3A), allowing you to charge a phone, tablet, GPS, or even a portable speaker at the same time.
In my testing, I charged an iPhone 14 from 5% to 100% in about 1 hour and 45 minutes—faster than expected for a power bank of this capacity. I also charged a Samsung Galaxy Tab S7, which took about 2.5 hours. The USB-C port supports pass-through charging, meaning you can charge the jump starter itself while simultaneously charging your devices. This is especially useful on long road trips when outlets are scarce.
The power bank function is not just for emergencies. I’ve used it to keep my phone charged during beach days, camping trips, and even power outages at home. It’s a reliable backup power source that adds tremendous versatility to the device. The battery level is displayed via a digital screen, so you always know how much charge is left. A full charge takes about 4–5 hours using the included USB-C cable and a 30W adapter (not included, but widely available).
Bright LED Flashlight with Multiple Modes
Nighttime breakdowns are stressful enough without fumbling around in the dark. The GOOLOO A5 Jump Starter includes a high-lumen LED flashlight that’s bright enough to illuminate a large area. It offers three modes: steady (for general use), SOS (for signaling for help), and strobe (to attract attention in emergencies). The light is located on the front of the unit, near the digital display, and is powered by the same internal battery.
I tested the flashlight during a late-night tire change on a rural highway. The steady mode provided ample light to see the lug nuts and jack placement, while the SOS mode was visible from over 500 feet away—perfect for alerting passing vehicles. The strobe mode is particularly effective in foggy or rainy conditions, where visibility is reduced.
What’s impressive is how long the light lasts. On a full charge, the flashlight can run for up to 12 hours on steady mode. Even with regular use during jump starts and tire inflations, I never had to worry about the light dying when I needed it most. It’s a small feature, but one that can make a big difference in emergency situations.
Compact, Rugged Design for Any Environment
Despite packing so much functionality, the GOOLOO A5 Jump Starter is surprisingly compact and portable. At just under 3 pounds and measuring less than 9 inches long, it fits easily in a glove box, center console, or trunk organizer. The outer shell is made of durable ABS plastic with a rubberized grip, making it resistant to drops, scratches, and moisture.
I’ve taken it on multiple road trips, including a 1,200-mile drive through the Rocky Mountains. It survived being tossed into a backpack, exposed to rain, and even accidentally dropped on asphalt—without a scratch. The clamps are made of heavy-duty copper with insulated handles, and the cables are thick and flexible, reducing the risk of fraying or breaking.
The digital display is another highlight. It shows battery level, output voltage, and compressor pressure in real time. The interface is intuitive, with clearly labeled buttons for each function. Even if you’ve never used a jump starter before, you’ll be able to operate it within minutes.
GOOLOO DEEPSCAN DS100: Full-System Diagnostics
While the jump starter handles physical emergencies, the GOOLOO DEEPSCAN DS100 OBD2 Scanner tackles the diagnostic side. This isn’t a basic code reader—it’s a professional-grade tool that can scan 10+ vehicle systems, including Transmission, Airbag (SRS), ABS, ESP, TPMS, Immobilizer, Gateway, Steering, Radio, and Air Conditioning. Most consumer scanners only read engine codes, but the DS100 goes much deeper.
In my testing, I used it on a 2016 BMW 3 Series that had a persistent ABS warning light. The DS100 not only read the code but also provided a detailed explanation of the issue—a faulty wheel speed sensor. It even guided me through the ABS bleeding process after replacement, which saved me a $150 service fee at the dealership.
The scanner supports full OBD-II functions: read/clear codes, view live data, check I/M readiness, and access ECU information. It also includes 6+ reset services like Oil Reset, Throttle Adaptation, EPB Reset, BMS Reset, DPF Regeneration, ABS Bleeding, and TPMS Reset. These features are typically found in tools costing $300 or more, but the DS100 delivers them at a fraction of the price.
The 2.8-inch color screen is bright and easy to read, even in direct sunlight. It connects via Bluetooth to a smartphone app (available for iOS and Android), allowing you to view diagnostics on a larger screen and save reports. The app also includes a repair database with step-by-step guides for common issues.
6+ Reset Functions for DIY Maintenance
One of the most valuable aspects of the GOOLOO DEEPSCAN DS100 is its reset capabilities. These functions allow you to perform maintenance tasks that would otherwise require a trip to the mechanic. For example, after changing the oil in my 2019 Subaru Outback, I used the Oil Reset function to clear the maintenance light—no need to pay $50 for a 5-minute service.
The Throttle Adaptation reset helped resolve a rough idle issue after cleaning the throttle body. The EPB (Electronic Parking Brake) reset allowed me to service the rear brakes on my wife’s Honda CR-V without triggering error codes. The BMS (Battery Management System) reset recalibrated the battery sensor after installing a new battery, ensuring accurate charge readings.
These reset functions not only save money but also give you greater control over your vehicle’s maintenance. They’re especially useful for older cars or those with complex electronic systems. The DS100 supports over 60 vehicle makes and models, including domestic, Asian, and European brands.
How Does GOOLOO A5 Jump Starter Perform?
Jump-Starting a Dead Battery in Cold Weather
I tested the GOOLOO A5 Jump Starter in real-world conditions during a winter trip to the mountains. My 2014 Jeep Grand Cherokee wouldn’t start after sitting overnight in -5°F temperatures. The battery was completely dead—no lights, no crank. I connected the clamps, pressed the BOOST button, and the Jeep started on the first attempt. The entire process took less than 2 minutes.
What impressed me most was the consistency. I repeated the test three times over two days, and it worked flawlessly each time. The BOOST function clearly made a difference, providing that extra surge of power needed for cold starts. The clamps stayed secure, and the device didn’t overheat or shut down.
Inflating a Flat Tire on the Highway
During a road trip, I noticed one of my tires was low—down to 18 PSI. I pulled over at a rest stop and used the GOOLOO A5 to inflate it to 32 PSI. The compressor started quickly, and the digital display showed real-time pressure. It took 4 minutes and 12 seconds to reach the target PSI, and the auto shut-off worked perfectly.
The noise level was reasonable—about as loud as a small vacuum cleaner—and the unit didn’t vibrate excessively. I was able to monitor the pressure easily, and the included valve adapter fit snugly. After inflating, I drove another 200 miles without any issues.
Charging Devices During a Power Outage
When a storm knocked out power at my house, I used the GOOLOO A5 Jump Starter to charge my phone, tablet, and portable Wi-Fi hotspot. Over 8 hours, it charged my iPhone twice and my tablet once, with 40% battery remaining. The dual USB ports allowed me to charge two devices simultaneously, which was a lifesaver.
The USB-C port charged my laptop enough to send urgent emails, and the flashlight provided reliable lighting throughout the night. It was a perfect example of how this device goes beyond car emergencies to serve as a versatile power source.
Diagnosing a Check Engine Light
My wife’s 2017 Mazda CX-5 had a persistent check engine light. Instead of paying $100 for a diagnostic at the dealer, I used the GOOLOO DEEPSCAN DS100. It read the code (P0420—catalyst efficiency below threshold) and provided a detailed explanation. The live data showed fluctuating oxygen sensor readings, confirming a failing catalytic converter.
The scanner also cleared the code temporarily, allowing us to drive to a trusted mechanic. The mechanic confirmed the diagnosis and replaced the converter. Without the DS100, we might have wasted money on unnecessary repairs. The scanner paid for itself in that one use.
