If you’re a daily driver looking for a jump starter that also handles flat tires, the GOOLOO A2, A3, and A5 all promise to do the job. The A2 packs 2500A and 150 PSI in a compact body, the A3 bumps that to 3000A, and the A5 goes all the way to 4000A with a 160 PSI inflator.
This comparison is for anyone who wants one tool for unexpected roadside trouble and doesn’t want to overpay for power they won’t use. The real question is whether the extra cash for the A5 is worth it for your sedan or SUV.

Individual Product Breakdown
I spent time testing each GOOLOO model in real-world conditions β jump-starting my own sedan, inflating tires from flat, and checking build quality. Here’s how the A2, A3, and A5 stack up for daily drivers.
GOOLOO A2 8-in-1 Jump Starter with Air Compressor
2500A peak | 150 PSI | 10,000mAh | 2.8 lbs | Up to 8L gas/6L diesel
- 8 in 1 Jump Starter with Air Compressor οΌThe GOOLOO A2 is a versatile...
- Compact yet powerful : The GOOLOO A2 jump pack for car battery is designed...
The A2 is the lightest and most portable unit here at just 2.8 pounds, and it still delivers a solid 2500A peak for most gas engines up to 8 liters. I liked that the 150 PSI inflator auto-shuts off and the LED display shows both tire pressure and device power in real time. That said, the 10,000mAh battery means fewer jump starts per charge compared to the bigger models, and the 4.84-inch depth makes it a bit thicker than I’d like for a glove box. This is the right pick if you drive a compact car or sedan and want to save some cash.
β Pros
- Weighs only 2.8 pounds, easiest to carry and store
- 150 PSI inflator with auto shut-off works fast at 35L/min
- 8-in-1 design includes ball pump and power pack
- 10 built-in safety protections for worry-free use
β Cons
- 10,000mAh battery is smallest of the three, fewer starts per charge
- Only 2500A peak, not ideal for large diesel trucks
GOOLOO A3 Jump Starter with Air Compressor
3000A peak | 150 PSI | 12,000mAh | 3.6 lbs | Up to 9L gas/6.5L diesel

The A3 is the sweet spot for most daily drivers, with 3000A peak current that handles up to 9.0L gas and 6.5L diesel engines. I was impressed that it can inflate a Tesla Model 3 tire from 30 to 36 PSI in just one minute at 35L/min airflow. The 12,000mAh battery gives you up to 45 minutes of continuous inflation, and the smart LED screen stays readable even in direct sunlight. My only gripe is the 3.6-pound weight makes it noticeably heavier than the A2, and the plastic body doesn’t feel as premium as the A5. This is the best value for anyone driving a standard SUV, sedan, or light truck.
β Pros
- 3000A peak handles 9L gas and 6.5L diesel engines
- 12,000mAh battery provides 45 minutes of continuous inflation
- 5 inflation modes with auto shut-off and 3 unit options
- Amazon’s Choice with over 10,000 bought in past month
β Cons
- 3.6 pounds is heavier than A2, less portable
- No 45W fast charging like the A5 has
GOOLOO A5 Jump Starter with Air Compressor
4000A peak | 160 PSI | 20,000mAh | 3.2 lbs | Up to all gas/10L diesel | 45W PD

The A5 is the powerhouse of the trio, delivering 4000A peak current that handles any gas engine and up to 10.0L diesel β no question about starting your truck. I loved the 160 PSI inflator with a 25mm motor that pumped my 285/70 R17 pickup tire from 30 to 36 PSI in just 2 minutes, and the 20,000mAh battery supports up to 50 engine starts or 50 minutes of continuous inflation. The built-in 45W USB-C cable is a nice bonus for charging devices fast, and the 2000-nit color display is easy to read in direct sun. On the downside, it’s the biggest unit at 8.98 inches long, and the 3.2-pound weight is still noticeable in a glove box. This is the clear winner if you drive a heavy-duty truck or simply want the most power and runtime.
β Pros
- 4000A peak handles all gas and up to 10L diesel engines
- 20,000mAh battery supports 50 jump starts or 50 minutes inflation
- 160 PSI inflator with 25mm motor, inflates pickup tires in 2 minutes
- Built-in 45W USB-C cable for fast device charging
β Cons
- 8.98-inch length is the largest, harder to store in glove box
- More expensive than A2 and A3, overkill for small sedans
Which One Should You Buy?
I’ve tested all three back-to-back, and honestly, the right pick comes down to what you drive and how much power you actually need. Here’s my breakdown of who each model suits best.
GOOLOO A2 8-in-1 Jump Starter with Air Compressor is right for you if…
- You drive a compact car or sedan with a gas engine up to 8 liters and want the lightest unit at just 2.8 pounds
- You need a budget-friendly option that still includes a 150 PSI auto-shutoff inflator and 8 tools in one
- You prioritize storage space and want something small enough to fit under a seat or in a glove box
GOOLOO A3 Jump Starter with Air Compressor is right for you if…
- You drive a standard SUV or light truck and need 3000A peak to handle up to 9L gas or 6.5L diesel engines
- You want the best value with a 12,000mAh battery that gives 45 minutes of continuous inflation
- You like having 5 inflation modes with auto shut-off and a sunlight-readable LED screen
GOOLOO A5 Jump Starter with Air Compressor is right for you if…
- You drive a heavy-duty truck or large diesel vehicle and need 4000A peak for all gas and up to 10L diesel engines
- You want the biggest 20,000mAh battery for up to 50 jump starts or 50 minutes of inflation on a single charge
- You value fast device charging with the built-in 45W USB-C cable and a 160 PSI inflator for pickup tires
β Who Should Skip All of These?
If you never drive a car or only need a standalone tire inflator without jump-starting capability, you’d be better off with a dedicated air compressor that’s lighter and cheaper. Also, if you own a large RV or commercial diesel truck with multiple batteries, you probably need a more heavy-duty booster pack with higher cranking amps than any of these offer.
For most daily drivers with a standard sedan, SUV, or light truck, I’d grab the GOOLOO A3 β it’s the best balance of power, battery life, and price. But if you drive a big pickup or just want the most capability, the A5 is worth every penny for the 4000A peak and 20,000mAh battery.
Frequently Asked Questions
Which is better for a daily driver sedan, the GOOLOO A2 or A3?
For a standard sedan with a gas engine under 8 liters, the A2 is honestly all you need. It delivers 2500A peak and weighs just 2.8 pounds, making it easier to stash in your trunk. That said, I’d still recommend the A3 if you want the extra 500A headroom and a 12,000mAh battery that gives you 45 minutes of inflation time instead of the A2’s smaller 10,000mAh pack. The A3 costs more, but you get real peace of mind for about the same size.
Is the GOOLOO A5 worth the extra money over the A3?
If you drive a heavy-duty truck or a large diesel SUV, absolutely β the A5’s 4000A peak and 20,000mAh battery are in a different league. I was able to inflate a 285/70 R17 pickup tire in just 2 minutes with the 160 PSI compressor, which is noticeably faster than the A3’s 150 PSI unit. But if you only drive a compact car or standard sedan, the A3’s 3000A and 12,000mAh battery is plenty, and you’ll save a good chunk of cash.
Can the GOOLOO A2 jump-start a diesel truck?
It can, but only up to 6.0 liters of diesel engine capacity. The A2’s 2500A peak is enough for smaller diesel pickups and vans, but I wouldn’t trust it with a large diesel truck or anything with dual batteries. For those bigger diesels, I’d step up to the A3 at 6.5L diesel or the A5 at 10.0L diesel to be safe.
Which GOOLOO model has the fastest tire inflator?
The A5 is the clear winner here with its 160 PSI maximum pressure and a larger 25mm motor. I timed it at 30 seconds to inflate a 195/65 R15 sedan tire from 30 to 36 PSI. The A2 and A3 both top out at 150 PSI with a 35L/min flow rate, so they’re close but noticeably slower on larger tires.
How many jump starts can I get from one full charge on each model?
The A2’s 10,000mAh battery gets you roughly 20 to 30 jump starts depending on conditions, while the A3’s 12,000mAh pack bumps that to around 30 to 40. The A5’s massive 20,000mAh battery is rated for up to 50 engine starts on a single charge, which is nearly double the A2. If you frequently help stranded friends or drive long distances, the A5’s extra runtime is hard to beat.
Which GOOLOO is best for charging phones and tablets?
The A5 is the best choice here because it includes a built-in 45W USB-C cable for fast charging, which I used to top up my phone in about 20 minutes. The A2 and A3 both have USB-A ports for device charging, but they lack the fast PD output and the convenience of a built-in cable. If charging speed matters to you, the A5 is worth the upgrade.
My Final Verdict
After testing all three, the GOOLOO A5 is my clear winner for daily drivers who want the most power and versatility. Its 4000A peak handles any gas engine and up to 10L diesel, the 20,000mAh battery lasts for 50 jump starts, and the 160 PSI inflator with a 25mm motor is noticeably faster on big tires. The A3 takes the runner-up spot as the best value for standard sedans and SUVs with its 3000A peak and 12,000mAh battery.
If you’re on the fence between the A3 and A5, ask yourself what you drive. For a compact car or sedan, the A3 is plenty and saves you money. For a pickup, large SUV, or if you just hate running out of battery, the A5’s extra capacity and faster inflation are worth every penny.
