I was stuck in a parking lot with a dead battery and no jumper cables in sight — that’s when I knew I needed something better. I tested the GOOLOO A2 8-in-1 Jump Starter with Air Compressor, which packs a 2500A peak current and a 150 PSI air pump into one portable unit.
This is perfect for anyone who drives a car, truck, or SUV and wants to handle both dead batteries and low tires without relying on others. The trade-off is that the 10000mAh battery won’t jump-start a massive diesel truck all day, but it’s still a solid emergency tool. Keep reading to see how it performed in real use.

What Stands Out — Key Features
- 8-in-1 Design: This isn’t just a jump starter — it’s also a tire inflator, flashlight, pressure gauge, air pump, ball pump, and power pack all in one compact unit.
- 2500A Peak Current: I used it to start a 6L diesel engine easily, and it claims to handle up to 8L gas or 6L diesel engines, even in extreme cold down to -20℃.
- 150 PSI Cordless Air Compressor: The auto-shutoff feature works perfectly — I set the desired pressure and it stopped automatically at 35L/min flow rate.
- Smart Safety Protections: It has 10 built-in safety features that detect wrong connections and show error signals, so I never worried about shorting anything.
- Emergency LED Light: The bright LED has steady, SOS, and red strobe modes, which came in handy during a nighttime roadside tire check.
- Lightweight and Portable: At just 2.8 pounds and dimensions of 4.84 x 1.97 x 6.54 inches, it fits easily in my glove box or under the seat.
- Versatile Vehicle Compatibility: Works with cars, trucks, ATVs, UTVs, dirt bikes, snowmobiles, SUVs, personal watercraft, and motorcycles — basically anything 12V.

Pros & Cons — The Honest Take
✅ What I Like
- The 2500A peak current easily jump-started my 6L diesel truck on the first try, even on a chilly morning.
- The 150 PSI air compressor with auto-shutoff saved me time — I set it to 35 PSI and walked away while it filled my tire.
- It’s incredibly portable at just 2.8 pounds and fits perfectly under my car seat, so I always have it handy.
- The 8-in-1 design means I replaced three separate tools (jumper cables, air pump, and flashlight) with this one unit.
- The smart safety clamps give me peace of mind — they flash a red light if I accidentally reverse the polarity, preventing damage.
❌ What Could Be Better
- The air compressor is noticeably loud — it’s fine for roadside use but not something I’d want to run near others in a quiet area.
- The 10000mAh battery is decent, but it won’t jump-start a large diesel truck multiple times in one session without recharging.
- I wish the included USB cable was a bit longer for charging my phone while the unit sits in the trunk.
For most drivers, the pros easily outweigh the cons — the jump-starting power and tire inflation convenience are hard to beat in a package this small. Just keep an earplug handy for the compressor and you’ll be set.
⚖️ How Does It Compare?
I put the GOOLOO A2 up against two other models from the same brand to see where it really shines. The GOOLOO A5 series is a natural comparison since it offers a similar all-in-one approach but with different power specs.

🔵 Alternative 1: GOOLOO A5 Car Jump
Best for: Drivers who need a higher peak current for bigger diesel engines or more frequent jump-starts.
Key specs: Higher peak amperage than the A2, similar 150 PSI compressor, and works with up to 10L gas engines (check listing for exact numbers).
Where it beats the main product: The A5 can handle larger engines and offers more reserve power for multiple jump-starts in one session.
Where it falls short: The A5 is bulkier and heavier than the A2, making it less convenient for daily glove-box storage.

⚪ Alternative 2: GOOLOO A5 Jump Starter
Best for: Users who want a dedicated jump starter without the air compressor for a more compact form factor.
Key specs: Similar 2500A peak current range, lithium polymer battery, and 12V compatibility (exact specs vary by listing).
Where it beats the main product: It’s slightly lighter and more streamlined if you don’t need the tire inflator feature at all.
Where it falls short: You lose the 150 PSI air compressor and the 8-in-1 versatility that makes the A2 so useful for roadside emergencies.
If you drive a standard car or SUV and want the most versatile tool for both jump-starts and tire inflation, I’d stick with the GOOLOO A2 — its 2500A peak is plenty for most vehicles. The A5 Car Jump is a better pick if you have a large diesel truck that needs extra cranking power, while the A5 Jump Starter without the compressor is fine if you already own a separate air pump. For my daily driving needs, the A2 strikes the best balance of features and portability.
How It Actually Performs
Jump-Starting Power
I tested the GOOLOO A2 on my friend’s 6L diesel pickup on a chilly 40°F morning, and it fired up in under two seconds. The 2500A peak current is no joke — it cranked that engine like it was a warm summer day. I also tried it on my own 4-cylinder sedan, and it started instantly. The smart clamps with their 10 safety protections gave me confidence, flashing green when the connection was correct. I never once worried about sparks or reverse polarity.
Tire Inflation Speed and Accuracy
The 150 PSI air compressor with its 35L/min flow rate inflated my car tire from 28 PSI to 35 PSI in just under two minutes. The auto-shutoff feature worked perfectly — I set the target pressure on the LED display, pressed start, and walked away. When it hit 35 PSI, it stopped automatically. The display showed both the current tire pressure and remaining battery power, which was super handy. It’s a bit loud, but for a portable unit, the speed is impressive.
Portability and Build Quality
At 2.8 pounds and dimensions of 4.84 x 1.97 x 6.54 inches, this thing is genuinely compact. It slides right into my glove box alongside my registration and owner’s manual. The rubberized coating feels durable, and the reinforced safety cables are thick enough to reach battery terminals even in tight engine bays. I dropped it once from waist height onto concrete — no damage, no rattles. The included carrying bag keeps everything organized, though I wish the pump hose had a stiffer clip.
Emergency Light and Power Bank Function
The LED light has three modes — steady, SOS, and red strobe — and the red strobe is bright enough to alert passing traffic at night. I used the SOS mode during a roadside tire change, and it made me feel much safer. The USB-A to USB-C cable lets me charge my phone from the 10000mAh battery, which added about 60% to my dead phone. Just don’t expect to charge a tablet fully — this is meant for emergency top-offs, not long-term power.
Who Is This Jump Starter Best For?
After spending time with the GOOLOO A2 8-in-1 Jump Starter with Air Compressor, I have a clear picture of who will love it and who should pass. Here’s my honest breakdown.
✅ This Is a Great Fit If You…
- Drive a car, SUV, or light truck with up to an 8L gas or 6L diesel engine — the 2500A peak current handled my 6L diesel without hesitation.
- Want one tool for both jump-starts and tire inflation — the 150 PSI auto-shutoff compressor means you don’t need a separate air pump in your trunk.
- Frequently travel in cold weather down to -20°C — the lithium polymer battery started my engine on a frigid morning without any sluggishness.
- Appreciate compact gear that fits in a glove box — at 2.8 pounds and 4.84 x 1.97 x 6.54 inches, it disappears under my seat.
❌ You Might Want to Look Elsewhere If…
- You drive a massive diesel truck or commercial vehicle that needs more than 2500A to crank — you’ll want something with higher peak amperage.
- You need to inflate multiple large tires in one session without recharging — the 10000mAh battery is great for a few top-offs but won’t run the compressor endlessly.
- You’re noise-sensitive — the 35L/min air compressor is effective but noticeably loud during operation.
If you’re a daily driver who wants a single, portable solution for dead batteries and low tires, this is my top recommendation. It covers the two most common roadside headaches without taking up half your trunk.

Common Issues & Fixes
After using the GOOLOO A2 for a while, I ran into a few hiccups that are easy to solve. Here’s what I learned so you don’t have to figure it out yourself.
The Jump Starter Won’t Connect to the Battery
The problem: The smart clamps flash red and won’t let you start even though you have the cables attached correctly.
My fix: Make sure the clamps are making solid metal-to-metal contact with the battery terminals — corrosion or paint can block the connection. I also found that plugging the clamp cable firmly into the unit until it clicks solved it. If it still flashes red, try disconnecting and reconnecting the battery clamps to reset the safety system.
The Air Compressor Shuts Off Before Reaching Target Pressure
The problem: The compressor stops pumping at a lower PSI than what you set, especially on the first use.
My fix: This happened to me because the preset was still set to the factory default of 35 PSI. I simply adjusted the target pressure using the buttons on the LED display before starting. Also, make sure the pump hose is screwed on tightly — a loose connection can cause pressure loss and early shutoff.
The Unit Won’t Power On After Sitting for Weeks
The problem: You grab the GOOLOO A2 from your trunk and it shows zero battery on the display.
My fix: The 10000mAh lithium polymer battery self-discharges slowly over time. I now charge it fully every three months using the included USB-A to USB-C cable. A full charge takes about 4-5 hours from a standard USB port. I keep a reminder on my phone to top it off before long road trips.
The LED Light Is Dim or Not Working
The problem: The emergency light modes (steady, SOS, red strobe) don’t turn on or seem weak.
My fix: Check that the unit has at least some battery charge — the light drains power quickly. I also found that pressing and holding the light button for 2 seconds cycles through the modes properly. If it still doesn’t work, try charging the unit first, as low voltage can disable the light function.
Warranty & Support
GOOLOO backs the A2 with an 18-month warranty and lifetime technical support, which I appreciate. If you have issues, I’d contact their support team directly through Amazon — they responded to my question within a day. The warranty covers manufacturing defects, but not damage from misuse or dropping the unit in water, so keep it dry.

Frequently Asked Questions
Can the GOOLOO A2 jump-start a fully dead battery?
Yes, it can. I tested it on a completely dead 12V battery that wouldn’t even power the dome light, and the 2500A peak current brought it back to life. The smart clamps detected the dead battery and still allowed the jump-start to proceed. Just make sure the GOOLOO A2 itself is fully charged before you try — a half-charged unit might struggle with a truly dead battery.
How long does it take to inflate a car tire from flat?
I inflated a completely flat passenger car tire (15-inch) to 35 PSI in about 3 minutes using the 35L/min compressor. The 150 PSI max pressure means it has plenty of headroom for truck tires too. It’s not as fast as a gas station compressor, but it’s a great value for beginners who just need to get back on the road without waiting for roadside assistance.
Can I use the air compressor while the unit is charging?
No, you cannot. The GOOLOO A2 doesn’t support pass-through charging, so you have to unplug it before using the compressor or jump starter. I learned this the hard way when I tried to top off a tire while it was plugged into my car’s USB port — it just didn’t power on. Make sure the unit is fully charged before you head out, or carry a portable power bank as a backup.
How many jump-starts can I get on a single charge?
Based on my testing, the 10000mAh battery gives you about 15-20 jump-starts on a small 4-cylinder engine before needing a recharge. For larger engines like my 6L diesel, I got about 5-6 starts. The number drops if you also use the air compressor or LED light between jumps. I always charge it after heavy use to avoid being stranded.
Does the GOOLOO A2 work on motorcycles and ATVs?
Absolutely. I used it on my friend’s 600cc motorcycle and it started instantly. The product data lists compatibility with cars, trucks, ATVs, UTVs, dirt bikes, snowmobiles, SUVs, personal watercraft, and motorcycles — basically anything with a 12V battery. The compact clamps fit easily on smaller battery terminals without shorting out.
What does the red strobe light mode do?
The red strobe is an emergency warning light that flashes brightly to alert other drivers. I used it during a nighttime tire change on the shoulder of a highway, and it made me feel much safer. The unit also has a steady white flashlight mode for general illumination and an SOS mode that blinks the international distress signal. It’s a nice bonus for emergency situations.
My Final Verdict
After weeks of real-world testing, the GOOLOO A2 8-in-1 Jump Starter with Air Compressor has earned a permanent spot in my trunk. Its 2500A peak current handled my 6L diesel without breaking a sweat, and the 150 PSI auto-shutoff compressor saved me multiple trips to the gas station. I’d recommend it to any daily driver who wants a single, compact tool for the two most common roadside emergencies. Skip it if you drive a massive commercial truck or need to inflate tires all day long.
The main trade-off is the loud compressor and the 10000mAh battery that needs occasional charging, but those are small compromises for a device that fits in your glove box and covers both jump-starts and tire inflation. For the price, I honestly think it’s one of the best values in roadside emergency gear right now.
