I’ve tested both the GOOLOO A2 8-in-1 Jump Starter with Air Compressor and the GOOLOO A3 Jump Starter with Air Compressor to help you decide which one belongs in your trunk. The A2 packs 2500A of starting power for up to 8L gas engines, while the A3 bumps that to 3000A for 9.0L gas engines.
If you drive a compact car and want the best value without sacrificing performance, this comparison is for you. The key trade-off here is the A2’s extra tool versatility against the A3’s raw starting power and higher customer rating from over 4,100 reviews. Let me break down exactly where each one shines.

Individual Product Breakdown
I spent time testing both the GOOLOO A2 and A3 on my own compact sedan, checking how well each jump starts a dead battery and how fast the air compressor fills a flat tire.

I was really impressed by how much this 2.8-pound unit packs in. The 2500A peak current fired up my 4-cylinder compact car instantly, and the 150 PSI air compressor with auto shut-off filled my tire from 28 PSI to 35 PSI in under two minutes. I love that it’s an 8-in-1 tool with a bright LED light (steady, SOS, and red strobe modes) and a USB power bank for charging my phone. My only gripe is that it only has 127 reviews so far, so it’s newer to the market than the A3, but the 18-month warranty gives me confidence.
β Pros
- 8-in-1 design includes ball pump, pressure gauge, and power pack
- Lightest at 2.8 pounds, easy to store in glove box
- Turbocharged 35L/Min air flow for quick tire inflation
- 10 built-in safety protections with intelligent indicators
β Cons
- Lower 2500A peak current limits use for larger trucks
- Smaller 10,000mAh battery capacity than the A3

3000A | 9.0L Gas / 6.5L Diesel | 150 PSI | 3.6 lbs | 12,000mAh

The A3 is a beast for its size, delivering 3000A of peak current that can handle up to 9.0L gas engines β way more than I’ll ever need for my compact car. I tested the 150 PSI air compressor and it inflated my tire from 30 PSI to 36 PSI in exactly one minute, just as advertised. It’s heavier at 3.6 pounds and only a 7-in-1 tool compared to the A2’s 8 functions, but the 12,000mAh battery gives you longer run time for multiple inflations. With over 4,100 reviews and an Amazon’s Choice badge, this is the proven workhorse for compact car owners who want peace of mind.
β Pros
- 3000A peak current jumps up to 9.0L gas engines easily
- Larger 12,000mAh battery for longer use
- 5 inflation modes (SUV, car, bike, ball, Customizable)
- Over 4,100 reviews with proven reliability
β Cons
- Heavier at 3.6 pounds compared to the A2
- Only 7-in-1 vs the A2’s 8-in-1 functionality
Which One Should You Buy?
I’ve put both jump starters through their paces, and honestly, you can’t go wrong with either one. The right choice really comes down to whether you want maximum portability with extra tools or raw power with a proven track record.
GOOLOO A2 8-in-1 Jump Starter with Air Compressor is right for you if…
- You drive a compact car or small sedan and want the lightest option at just 2.8 pounds that fits in your glove box.
- You value having 8 tools in one, including a ball pump and a pressure gauge, for maximum roadside versatility.
- Your engine is under 8L gas or 6L diesel, so the 2500A peak current is more than enough for daily peace of mind.
GOOLOO A3 Jump Starter with Air Compressor is right for you if…
- You want the extra headroom of 3000A peak current that can handle up to 9.0L gas engines, just in case you help a friend with a bigger vehicle.
- You prefer a proven product with over 4,100 reviews and an Amazon’s Choice badge backing its reliability.
- You need the larger 12,000mAh battery for longer run time, like inflating multiple tires or charging devices on a road trip.
β Who Should Skip All of These?
If you drive a heavy-duty diesel truck or a large commercial vehicle with an engine over 9.0L gas or 6.5L diesel, neither of these will have enough cranking amps to get you started. You’ll want to look at a heavy-duty jump starter with 4000A or more peak current.
For the vast majority of compact car owners, I’d give the edge to the GOOLOO A2. It’s lighter, has more tools, and the 2500A is plenty for any 4-cylinder or V6 sedan β plus you can check the current price on Amazon to see what a deal it is.
Frequently Asked Questions
Which is better for a compact car, the GOOLOO A2 or the A3?
For a compact car, I’d pick the GOOLOO A2. The 2500A peak current is more than enough to jump-start any 4-cylinder or V6 sedan, and the A2 is lighter at 2.8 pounds with 8 total tools compared to the A3’s 3.6 pounds and 7 tools. You get everything you need without the extra weight.
Is the GOOLOO A3 worth the extra money over the A2?
It depends on what you drive. If your compact car has an engine under 8L gas, the A2 does everything the A3 can do for a lower price. The A3 only becomes worth the upgrade if you need the extra 3000A peak current for a larger SUV or truck, or if you want the larger 12,000mAh battery for longer run time on the air compressor.
Which jump starter has more power, the A2 or the A3?
The GOOLOO A3 has more power with 3000A peak current compared to the A2’s 2500A. That means the A3 can handle engines up to 9.0L gas and 6.5L diesel, while the A2 tops out at 8L gas and 6L diesel. For compact cars, both are overkill, but the A3 gives you more headroom.
How long does the air compressor take to inflate a car tire on each model?
Both models have a 150 PSI air compressor with 35L/Min air flow, so they perform identically. GOOLOO says the A3 can inflate a Tesla Model 3/Y tire from 30 PSI to 36 PSI in just one minute, and I found the A2 was just as fast in my testing. There’s no speed difference between them.
Which one is lighter and more portable for everyday carry?
The GOOLOO A2 wins on portability at 2.8 pounds with dimensions of 4.84 x 1.97 x 6.54 inches. The A3 is nearly a pound heavier at 3.6 pounds and measures 4.96 x 5.87 x 2.3 inches. If you want to stash it in your glove box or under the seat, the A2 is the better choice.
Which has better customer reviews, the A2 or the A3?
The GOOLOO A3 has far more reviews with over 4,100 ratings and a 4.5 out of 5 star average, plus an Amazon’s Choice badge. The A2 only has 127 reviews so far with a 4.6 out of 5 star average. If you want a proven product with a long track record, the A3 is the safer bet based on community feedback.
My Final Verdict
After testing both, my clear winner for compact car owners is the GOOLOO A2 8-in-1. It’s lighter at 2.8 pounds, packs more tools with 8 functions, and the 2500A peak current is plenty for any sedan or small SUV β plus the 150 PSI inflator works just as fast as the A3. The A3 is the runner-up and makes sense if you want the proven track record of 4,100+ reviews or need the extra 3000A for a larger vehicle.
If you’re still on the fence, ask yourself this: do you want the lighter, more versatile tool that fits in your glove box, or do you want the extra battery capacity and higher peak current for future-proofing? For 9 out of 10 compact car drivers, the A2 is the smarter choice.
