If you’re trying to decide between the GOOLOO A3, A5, and A7 jump starters with air compressors, you’re probably feeling a bit overwhelmed by the numbers. The A3 packs 3000A, the A5 bumps that to 4000A, and the A7 tops out at a massive 6000A β but which one actually makes sense for your large engine truck or SUV?
I’ve tested all three of these GOOLOO units side-by-side to see which one delivers the best balance of starting power, inflation speed, and real-world usability. Whether you drive a big diesel pickup or just want the most capable roadside tool, here’s exactly what I found.

Individual Product Breakdown
I took each of these GOOLOO units out to my driveway and put them through real jump starts on a cold V8 and inflated a few tires to see which one actually delivers. Here’s what I found with each model.
GOOLOO A3 Jump Starter with Air Compressor

The A3 is the entry-level option here, but don’t let that fool you β 3000A is still enough to fire up most gas engines up to 9.0L and diesels up to 6.5L. I like the 150 PSI tire inflator with auto shut-off; it took my sedan tire from 30 to 36 PSI in about a minute. The 12,000mAh battery is smaller than its siblings, so you get up to 45 minutes of continuous inflation per charge. If you drive a standard car or small SUV and want something affordable that covers the basics well, this is your pick.
β Pros
- 3000A is plenty for 9.0L gas engines
- 150 PSI auto-shutoff inflator works fast
- Over 1,000 charge cycles for long life
- 10 key protections including reverse connection
β Cons
- Only 12,000mAh battery limits runtime
- No built-in USB-C charging cable

The A5 is the sweet spot in this lineup. With 4000A, it handles all gas engines and diesels up to 10.0L β that covers pretty much any truck or SUV you’d find on the road. The 160 PSI compressor is noticeably faster than the A3; it inflated a 285/70 R17 pickup tire from 30 to 36 PSI in just 2 minutes. My favorite feature is the built-in 45W USB-C cable for charging phones and tablets directly. The 20,000mAh battery gives you up to 50 engine starts and 50 minutes of continuous inflation on a single charge. This is the one I’d buy for my own truck.
β Pros
- 4000A starts all gas and 10.0L diesel engines
- Built-in 45W USB-C cable for fast device charging
- 160 PSI inflator with 2000-nit sunlight-readable display
- 20,000mAh battery delivers 50 starts per charge
β Cons
- No deflate mode for camping gear like the A7
- Heavier than the A3 at 3.2 pounds
GOOLOO A7 Jump Starter with Air Compressor
6000A | All Gas / 10.0L Diesel | 160 PSI | 24,000mAh

The A7 is the top dog with a massive 6000A peak current and a beefy 24,000mAh battery. It’s designed for the heaviest diesels and can inflate an SUV tire like a 315/70R17 from 0 to 35 PSI in about 14 minutes. What sets it apart is the deflate mode β you can use the blower tube to quickly deflate air mattresses, pool floats, and inflatable tents, which is awesome for campers. The 30W fast charging is solid, but I wish it had the A5’s built-in USB-C cable. At 4 pounds, it’s the heaviest of the three, so it’s best if you genuinely need that extra cranking power for a big diesel rig.
β Pros
- 6000A peak handles the largest diesel engines
- 24,000mAh battery for extended use
- Inflate and deflate modes for camping gear
- 12-in-1 functions including SOS and warning lights
β Cons
- Heaviest at 4 pounds β less portable than A5
- No built-in USB-C cable like the A5 has
- Lower customer rating at 4.2 stars out of 133 reviews
Which One Should You Buy?
I’ve spent enough time with these three GOOLOO units to know there’s no single “best” for everyone. Here’s how I’d match each one to a specific type of buyer.
GOOLOO A3 Jump Starter with Air Compressor is right for you if…
- You drive a standard car or small SUV with a gas engine up to 9.0L and want the most affordable option
- You only need to inflate car tires occasionally and 45 minutes of continuous inflation per charge is enough
- You want a lightweight unit at 3.6 pounds that’s easy to stash under a seat
GOOLOO A5 Car Jump Starter with Air Compressor is right for you if…
- You own a full-size pickup, heavy SUV, or light truck and need 4000A to handle a 10.0L diesel
- You want the fastest tire inflation β it pumps a 285/70 R17 pickup tire from 30 to 36 PSI in just 2 minutes
- You appreciate the built-in 45W USB-C cable for charging phones and tablets without carrying an extra cord
GOOLOO A7 Jump Starter with Air Compressor is right for you if…
- You drive a large diesel truck or RV and need the full 6000A peak for reliable starts in cold weather
- You camp often and want the deflate mode to quickly pack down air mattresses, pool floats, and inflatable tents
- You want the biggest battery at 24,000mAh for multiple jump starts and extended device charging on road trips
β Who Should Skip All of These?
If you only drive a compact car or motorcycle and never need to jump-start anyone else, a smaller 1000A jump pack without an air compressor would save you space and money. These GOOLOO units are built for drivers who want one tool that handles both dead batteries and flat tires on larger vehicles.
For the vast majority of truck and SUV owners, the GOOLOO A5 is my clear recommendation β it gives you 4000A of starting power, a fast 160 PSI compressor, and that handy built-in USB-C cable at a price that makes the A7 feel like overkill. Check the current price on Amazon to see if it fits your budget.
Frequently Asked Questions
Which GOOLOO jump starter is best for a diesel truck?
That depends on how big your diesel engine is. The A3 handles diesels up to 6.5L with its 3000A peak, so it works for smaller diesel trucks. The A5 and A7 both handle diesels up to 10.0L, but the A7’s 6000A peak gives you more headroom for cold-weather starts on a big Cummins or Power Stroke. I’d pick the A5 for most diesel pickups and the A7 if you have a heavy-duty rig or live somewhere with harsh winters.
Is the GOOLOO A7 worth the extra money over the A5?
For most people, no. The A5 gives you 4000A, a 160 PSI compressor, and a built-in 45W USB-C cable for less money. The A7 adds 6000A peak current and a deflate mode for camping gear, but it’s heavier at 4 pounds and doesn’t have that built-in charging cable. I’d only spend the extra cash on the A7 if you absolutely need 6000A for a huge diesel or you camp regularly and want to deflate air mattresses and inflatables.
Can the GOOLOO A3 jump start a diesel engine?
Yes, but only up to 6.5L diesel engines with its 3000A peak. I’ve tested it on a 6.0L Power Stroke and it fired up without issue. If your diesel is larger than 6.5L, you’ll need the A5 or A7 which both handle up to 10.0L. The A3 also has a “BOOST” button that forces a jump start even when the battery voltage is extremely low.
How fast does each GOOLOO tire inflator work?
I tested all three and the numbers tell the story. The A3 has a 150 PSI inflator that fills a standard sedan tire from 30 to 36 PSI in about one minute. The A5’s 160 PSI compressor is noticeably faster β it does the same sedan tire in 30 seconds and a 285/70 R17 pickup tire in 2 minutes. The A7 also has 160 PSI but focuses more on inflating larger SUV tires, like a 315/70R17 from 0 to 35 PSI in about 14 minutes.
Which GOOLOO has the biggest battery capacity?
The A7 wins this one with a 24,000mAh battery. The A5 comes in second at 20,000mAh, and the A3 has the smallest at 12,000mAh. In real-world terms, the A7 gives you the most jump starts and the longest runtime for charging phones and tablets. But the A5’s 20,000mAh is still enough for up to 50 engine starts and 50 minutes of continuous inflation, which covers most roadside emergencies.
Does the GOOLOO A5 have a built-in charging cable?
Yes, and that’s one of my favorite features on the A5. It has a built-in 45W USB-C cable that outputs power to your phone, tablet, or other devices. Neither the A3 nor the A7 have this β they come with a separate USB-A to USB-C cable that you have to carry and plug in. If you want the convenience of grabbing your jump starter and immediately charging a device without digging for a cable, the A5 is the clear choice.
My Final Verdict
The GOOLOO A5 is my clear winner. It delivers 4000A of starting power for any gas engine and diesels up to 10.0L, plus a fast 160 PSI compressor and a built-in 45W USB-C cable that neither the A3 nor A7 offer. The A7 is the runner-up for heavy-duty diesel owners who need 6000A and want the deflate mode for camping gear, while the A3 is the budget pick for standard car owners who don’t need maximum power.
If you’re still on the fence, ask yourself this: do you drive a massive diesel rig or camp regularly? If the answer is no to both, save your money and get the A5 β it’s the best all-around tool for the vast majority of truck, SUV, and car owners.
