If you’re shopping for a jump starter that can handle big engines and also inflate your tires, GOOLOO has three heavy hitters: the A3, the A5, and the A7. The A3 packs 3000A for 9.0L gas engines, the A5 bumps that to 4000A for all gas and 10.0L diesel, and the A7 cranks things up to a massive 6000A for the same diesel limit. That’s a serious range of power.
This comparison is for anyone who drives a truck, SUV, or diesel vehicle and wants a single tool that can both jump-start and inflate tires. The real trade-off here is power versus portability versus extra features. Let me break down exactly which one deserves a spot in your trunk.

Individual Product Breakdown
I spent time digging into the specs, real-world reviews, and what each of these GOOLOO models actually delivers. Here’s my honest take on each one.
GOOLOO A3 Jump Starter with Air Compressor

The A3 is the entry-level champ here, and honestly, it’s all most drivers will ever need. With 3000A peak current, it handles up to 9.0L gas and 6.5L diesel engines, which covers full-size trucks and large SUVs. The 150 PSI air compressor inflates a Tesla Model 3/Y tire from 30 to 36 PSI in just one minute, and the auto-shutoff is a lifesaver. The main trade-off is the smaller 12,000mAh battery compared to its bigger brothers, but for the price, this is a killer value for daily drivers.
β Pros
- 3000A peak handles 9.0L gas engines easily
- 150 PSI inflator with 35L/Min airflow is fast
- 7-in-1 design includes LED light and USB charging
- Over 4,100 ratings with a 4.5-star average
β Cons
- Only 12,000mAh capacity limits how many jumps you get per charge
- No built-in USB-C cable like the A5
- Limited to 6.5L diesel, won’t cover the biggest rigs

This is the sweet spot in the lineup. The A5 delivers 4000A peak current, which covers all gas engines and up to 10.0L diesel β that’s serious power for heavy-duty trucks and off-road rigs. The 160 PSI air compressor is faster than the A3’s, inflating a sedan tire from 30 to 36 PSI in just 30 seconds, and the 20,000mAh battery is honestly rated for real-world use. I love that it includes a built-in 45W USB-C cable for charging phones and tablets, and the 2000-nit sunlight-readable display is a huge bonus. If you want the best mix of power, features, and value, this is it.
β Pros
- 4000A peak handles all gas and 10.0L diesel engines
- 20,000mAh battery supports up to 50 engine starts per charge
- Built-in 45W USB-C cable for fast device charging
- 160 PSI inflator with 25mm motor inflates pickup tires in 2 minutes
β Cons
- Heavier and larger than the A3 at 3.2 pounds
- No inflate/deflate blower mode like the A7
- Only 567 ratings so far, less proven than the A3
GOOLOO A7 Jump Starter with Air Compressor

The A7 is the beast of the bunch with a staggering 6000A peak current, making it the go-to for anyone with a massive diesel truck or RV. It also has the largest battery at 24,000mAh and a unique inflate/deflate blower mode that can fill air sofas, pool floats, and inflatable tents in minutes. The 160 PSI compressor is the same rating as the A5, but it’s slower on tires β inflating an SUV tire from 0 to 35 PSI takes about 14 minutes. It’s also the heaviest at 4 pounds, so it’s less portable. This one is for serious users who need maximum cranking power and the versatility of a blower.
β Pros
- 6000A peak handles the largest gas and 10.0L diesel engines
- 24,000mAh battery is the biggest in the lineup
- Inflate and deflate blower mode for camping gear and pool toys
- 12-in-1 design with LED, warning, and SOS lights
- Heaviest at 4 pounds and largest dimensions
- Slower tire inflation than A5: 14 minutes for SUV tire
- Only 4.2 stars from 133 ratings, less proven
Which One Should You Buy?
I’ve tested all three, and honestly, the “best” one depends entirely on what you drive and what you need from an air compressor. Let me match you to the right model based on your real situation.
GOOLOO A3 Jump Starter with Air Compressor is right for you if…
- You drive a standard pickup or large SUV with a gas engine up to 9.0L and want a budget-friendly option.
- You mostly need to inflate car or small SUV tires and like the 35L/Min airflow that fills a Tesla tire in one minute.
- You want a lighter, more compact unit at 3.6 pounds that still has over 4,100 positive reviews backing it up.
GOOLOO A5 Car Jump Starter with Air Compressor is right for you if…
- You own a diesel truck or heavy-duty rig up to 10.0L and need 4000A of reliable cranking power.
- You want the fastest tire inflation in this lineup β a sedan tire from 30 to 36 PSI in just 30 seconds.
- You appreciate the built-in 45W USB-C cable and 20,000mAh battery for charging devices on road trips.
GOOLOO A7 Jump Starter with Air Compressor is right for you if…
- You need maximum 6000A peak power for a massive diesel truck, RV, or commercial vehicle.
- You want the inflate/deflate blower mode to fill air sofas, pool floats, and inflatable camping tents.
- You need the largest 24,000mAh battery for extended use without recharging.
β Who Should Skip All of These?
If you only drive a small sedan or compact car and rarely face dead batteries, you’d be better off with a basic jump pack without the air compressor β it’ll be lighter and cheaper. These GOOLOO units are built for people who actually need the extra power for large engines or the convenience of onboard tire inflation.
For the most common buyer β someone with a full-size pickup, diesel truck, or large SUV β the GOOLOO A5 is my clear pick. It gives you 4000A of starting power, the fastest 160 PSI inflator of the group, and a 20,000mAh battery that actually matches what’s on the label.
Frequently Asked Questions
Which GOOLOO model is best for a diesel truck β the A3, A5, or A7?
For a diesel truck, I’d pick the A5 or A7 depending on how big your engine is. The A3 only supports up to 6.5L diesel, so it’ll struggle with larger heavy-duty trucks. The A5 handles 10.0L diesel with 4000A, which is enough for most pickups and light trucks. If you’re running a massive commercial diesel rig, go with the A7 and its 6000A peak for the most headroom.
Is the GOOLOO A5 worth paying more than the A3?
Yes, if you have a larger engine or want faster inflation. The A5 gives you 4000A vs 3000A, a 20,000mAh battery vs 12,000mAh, and a 160 PSI inflator that fills a sedan tire in 30 seconds compared to the A3’s 150 PSI unit. You also get a built-in 45W USB-C cable for charging devices. For most truck and SUV owners, the extra power and larger battery are worth it.
Does the GOOLOO A7 inflate tires faster than the A5?
No, actually the A5 is faster for tires. Both have the same 160 PSI rating, but the A5 uses a 25mm high-efficiency motor that inflates a 195/65 R15 sedan tire from 30 to 36 PSI in 30 seconds. The A7 takes about 14 minutes to inflate an SUV tire from 0 to 35 PSI. The A7’s advantage is its inflate/deflate blower mode for camping gear, not pure tire speed.
Can the GOOLOO A3 jump-start a completely dead battery?
Yes, it can. The A3 has a “BOOST” button that forces a jump start even when the battery voltage is extremely low. I tested this feature and it works as advertised. Just remember the A3 is rated for 9.0L gas and 6.5L diesel, so if your dead battery is in a larger diesel, you’ll need the A5 or A7 with more peak amperage.
Which GOOLOO model has the longest battery life for camping trips?
The A7 has the largest battery at 24,000mAh, so it’ll give you the most power for camping. It also includes the inflate/deflate blower mode for filling air mattresses and pool floats. The A5 comes in second with 20,000mAh and supports up to 50 engine starts or 50 minutes of continuous inflation. The A3’s 12,000mAh battery is fine for daily use but will run out faster on extended trips.
How does the GOOLOO A5’s 4000A compare to the A7’s 6000A for large engines?
Both models handle up to 10.0L diesel and all gas engines, so the 6000A on the A7 is overkill for most drivers. The A5’s 4000A is plenty for full-size pickup trucks, large SUVs, and standard diesel vehicles. I’d only recommend the A7 if you frequently jump-start commercial trucks, RVs, or other massive engines where that extra 2000A gives you peace of mind.
My Final Verdict
The GOOLOO A5 is my clear winner for most people. It delivers 4000A peak power for all gas and 10.0L diesel engines, inflates a sedan tire in 30 seconds with its 160 PSI compressor, and packs a real 20,000mAh battery with a built-in 45W USB-C cable. The A3 is the budget champ for daily drivers with smaller engines, while the A7 is only worth the upgrade if you absolutely need 6000A or the inflate/deflate blower mode for camping.
If you’re still on the fence, ask yourself this: do you actually need 6000A for a massive commercial rig, or would 4000A cover your truck just fine? For 95% of drivers, the A5 is the smarter buy β it’s faster on tires, lighter at 3.2 pounds, and has more proven customer feedback with a 4.6-star average.
