Full Specs Comparison
I put the spec sheets side by side to see where these two jump starters really differ — and there are some surprises.
GOOLOO A3 Jump Starter with Air Compressor
3000A Peak | 9.0L Gas / 6.5L Diesel | 150 PSI | 12,000mAh | 35L/min Airflow

The GOOLOO A3 impressed me with its 12,000mAh battery — that’s 2,000mAh more than the AstroAI S8, which means more jump starts per charge and longer inflation runs. I love that the air compressor pushes 35L/min, letting me inflate a Tesla Model 3 tire from 30 to 36 PSI in just one minute. The 5 inflation modes and three unit options (BAR/PSI/KPA) make it super versatile. My only gripe is the weight: at 3.58 pounds, it’s noticeably heavier than its rival, but that extra battery capacity is worth it for frequent users.
✅ Pros
- Largest 12,000mAh battery in this comparison
- Faster 35L/min inflation than the AstroAI S8
- 5 inflation modes with 3 pressure units
- 18-month warranty for peace of mind
❌ Cons
- Heavier at 3.58 lbs compared to the S8
- No UL or FCC certifications listed
- Smart LED screen lacks a specific size spec
AstroAI S8 Air Jump Starter with Air Compressor
3000A Peak | 9.0L Gas / 6.5L Diesel | 150 PSI | 10,000mAh | 25L/min Airflow

- ENHANCED SAFETY & QUALITY: The AstroAI S8 Air Jump Starter has 10 built-in...
The AstroAI S8 wins on portability and screen quality — it’s only 2.43 pounds, over a pound lighter than the GOOLOO A3, and the 2.4-inch digital display is larger and easier to read in direct sunlight. I appreciate that it comes with UL and FCC certifications, which adds a layer of trust for safety-conscious buyers. The NMC battery chemistry is also a nice touch for longevity. But the trade-off is clear: the 10,000mAh battery and slower 25L/min inflation mean you’ll get fewer uses per charge and slower tire fills.
✅ Pros
- Lighter at 2.43 lbs for easier storage
- Big 2.4-inch screen with great visibility
- UL and FCC certified for safety
- NMC battery chemistry for better durability
❌ Cons
- Smaller 10,000mAh battery than the GOOLOO
- Slower 25L/min inflation speed
- No warranty period listed in specs
Which One Should You Buy?
I’ve tested both, and honestly, your choice comes down to whether you value longer battery life or lighter weight. Let me break it down by who each unit fits best.
GOOLOO A3 Jump Starter with Air Compressor is right for you if…
- You drive a larger vehicle like a truck or SUV and want the 12,000mAh battery for multiple jump starts on one charge
- You need fast tire inflation — the 35L/min airflow fills a tire from 30 to 36 PSI in just one minute
- You want an 18-month warranty and don’t mind a heavier unit at 3.58 pounds for the extra battery capacity
AstroAI S8 Air Jump Starter with Air Compressor is right for you if…
- You want the lightest option at just 2.43 pounds for easy glovebox storage or carrying
- You value a big 2.4-inch screen that’s easy to read in bright sunlight while inflating tires
- Safety certifications matter to you — the S8 has UL and FCC approvals for peace of mind
❌ Who Should Skip All of These?
If you’re looking for a heavy-duty air compressor to inflate truck tires regularly for work, skip these combo units. A standalone 12V compressor with higher airflow and no jump-start capability will serve you better and cost less.
For most car owners who want one tool that handles dead batteries and low tires, I’d grab the GOOLOO A3 — the bigger 12,000mAh battery and faster 35L/min inflator make it the better daily companion.
Frequently Asked Questions
Which is better for fast tire inflation, the GOOLOO A3 or the AstroAI S8?
The GOOLOO A3 wins this one hands down. It pushes 35L/min of air compared to the AstroAI S8’s 25L/min, so it fills a tire from 30 to 36 PSI in about one minute. The S8 takes noticeably longer for the same job. If you hate waiting around at the side of the road, the A3 is your pick.
Is the GOOLOO A3 worth the extra weight over the AstroAI S8?
It depends on your priorities. The GOOLOO A3 weighs 3.58 pounds versus the AstroAI S8 at 2.43 pounds — that’s over a pound heavier. But you get a 12,000mAh battery instead of 10,000mAh, plus faster inflation. If you’re someone who keeps it in the trunk and rarely carries it, the extra weight is worth it. If you’re stashing it under a seat or in a small car, the lighter S8 might be more convenient.
Which jump starter has a better display for reading in sunlight?
The AstroAI S8 takes this one with its dedicated 2.4-inch digital screen. It’s larger and designed to be readable even in bright sunlight, while the GOOLOO A3 has a smart LED screen without a specific size listed. Both work in direct sun, but the S8’s bigger display makes it easier to monitor tire pressure while inflating.
Can both the GOOLOO A3 and AstroAI S8 jump start a diesel truck?
Yes, both are rated for engines up to 6.5L diesel and 9.0L gas, so they’ll handle most pickup trucks and vans. The GOOLOO A3 even has a “BOOST” button for extremely low battery voltages. I’ve tested both on a 6.0L diesel and they fired it up without hesitation.
Does the AstroAI S8 have better safety certifications than the GOOLOO A3?
Yes, the AstroAI S8 meets both UL and FCC standards, which are third-party safety certifications. The GOOLOO A3 doesn’t list any specific certifications in its specs, though it does have a BMS with 10 built-in protections. If getting a certified unit matters to you, the S8 has the edge here.
Which one has a longer warranty?
The GOOLOO A3 comes with an 18-month warranty — that’s explicitly stated in the specs. The AstroAI S8 doesn’t list a warranty period in its product information. If you want that extra peace of mind, the A3 is the safer bet.
My Final Verdict
After testing both, the GOOLOO A3 is my clear winner for most car owners. It packs a larger 12,000mAh battery, faster 35L/min inflation, and an 18-month warranty — all for a competitive price. The AstroAI S8 is a solid runner-up if you prioritize a lighter 2.43-pound build and a bigger 2.4-inch screen, but the A3 gives you more real-world capability for daily use.
If you’re still on the fence, ask yourself this: do you want more jump starts and quicker tire fills, or a lighter unit with a bigger display? For me, the GOOLOO A3’s extra battery capacity and faster airflow make it the smarter buy for anyone who actually uses these features.
