If you’re shopping for a heavy duty jump starter, you’ve likely landed on the GOOLOO A5, A7, or GT6000. I’ve spent time digging through the specs on all three β the A5 packs 4000A and a tire inflator, the A7 bumps that to 6000A with inflate and deflate, and the GT6000 also hits 6000A but focuses on lightning-fast 100W charging.
This comparison is for truck and SUV owners who need real starting power and versatile accessories. The big question is whether you want an all-in-one tool with an air compressor or pure power with the fastest recharge. I’ll help you pick the right one.

Individual Product Breakdown
I tested the specs, features, and real-world use cases for each of these GOOLOO jump starters to see which one fits different heavy duty needs. Here’s what I found.
GOOLOO A5 Car Jump Starter with Air Compressor
4000A Peak | 160 PSI Inflator | 20,000mAh | 45W USB-C Cable
- γ6-in-1, compact & road-readyγ The 2026 GOOLOO A5 jump starter is a...
- β€γ4000A peak for confident startsγ Powered by GOOLOOβs JUMPCORE...
The GOOLOO A5 is my pick for the budget-conscious buyer who still wants a built-in air compressor. The 4000A peak is enough for all gas and up to 10.0L diesel engines, and the 25mm motor inflates a 285/70 R17 pickup tire from 30 to 36 PSI in just 2 minutes. I like the sunlight-readable 2000-nit display and the integrated 45W USB-C cable, but the 20,000mAh battery is smaller than the other two options. This is a great choice if you drive a standard pickup or SUV and don’t need the extra power for the biggest diesel rigs.
β Pros
- 160 PSI auto-off tire inflator with 5 modes and 5 nozzles
- Compact at 8.98 x 5.55 x 2.40 inches and 3.2 pounds
- 2000-nit color display is easy to read in direct sun
- Supports up to 50 engine starts per charge
β Cons
- Only 4000A peak β not ideal for the biggest diesel engines
- 45W charging is slower than the GT6000’s 100W
GOOLOO A7 Jump Starter with Air Compressor

- Multifunctional Jump Starter with Air Compressor: GOOLOO A7 battery jumper...
The GOOLOO A7 is the most versatile tool in this lineup because it combines 6000A peak power with a 160 PSI air compressor that can both inflate and deflate. I love that it inflates a 315/70R17 SUV tire from 0 to 35 PSI in about 14 minutes and can also rapidly blow up air sofas and pool floats using the blower nozzles. The 24,000mAh battery is the largest of the three, and the 12-in-1 design includes an LED warning light and SOS mode. My main concern is the 4-pound weight, which makes it a bit heavier to lug around, but the trade-off is worth it for the extra power and features.
β Pros
- 6000A peak starts all gas and up to 10L diesel engines
- Dual-mode inflate and deflate for tires and inflatables
- 24,000mAh battery is the largest capacity here
- Includes 5 air nozzles and 5 blower nozzles
β Cons
- Heavier at 4 pounds compared to the A5’s 3.2 pounds
- No 100W fast charging β recharges slower than GT6000
- Customer rating of 4.2 out of 5 stars is lower than competitors
GOOLOO 6000A Jump Starter GT6000 with 100W Bi-Directional Fast Charge

The GOOLOO GT6000 is the speed demon of the group thanks to its 100W bi-directional charging that goes from 0 to 100% in just 1.4 hours. With 6000A peak power, it can start engines up to 12.0L diesel β the highest rating here β and the 27,000mAh battery gives it the longest standby time at 24 months. I also appreciate the 3.2-inch LED display and the 400-lumen flashlight with SOS and strobe modes. The downside is there’s no built-in air compressor, so if you need tire inflation, you’ll have to carry a separate unit. This is the best choice for drivers of massive diesel trucks who want the fastest recharge and don’t mind skipping the inflator.
β Pros
- 100W bi-directional charging recharges in 1.4 hours
- 6000A peak starts engines up to 12.0L diesel
- 27,000mAh battery with 24-month standby time
- Includes a 100W car charger in the box
β Cons
- No built-in air compressor β you’ll need a separate inflator
- Only 1.49 inches wide, but longer at 8.98 inches
Which One Should You Buy?
I’ve spent a lot of time with the specs on these three, and honestly, the right pick comes down to whether you need an air compressor, max starting power, or the fastest recharge. Here’s who each one is built for.
GOOLOO A5 is right for you if…
- You drive a gas pickup or SUV and want a compact all-in-one with a 160 PSI tire inflator that can top off a 285/70 R17 tire in 2 minutes.
- You want the smallest and lightest option here at 3.2 pounds and 8.98 x 5.55 x 2.40 inches.
- You like having a sunlight-readable 2000-nit display and an integrated 45W USB-C cable for charging devices.
GOOLOO A7 is right for you if…
- You own a heavy duty diesel truck or SUV and need 6000A peak power plus a 24,000mAh battery for multiple jump starts.
- You want both inflate and deflate capability β great for airing down tires off-road and inflating air sofas or pool floats.
- You value having 12 functions in one unit, including an LED warning light, SOS mode, and a blower for camping gear.
GOOLOO GT6000 is right for you if…
- You drive a massive diesel rig up to 12.0L and need the highest starting power here with 6000A peak.
- You hate waiting for your gear to charge β 100W bi-directional charging gets you from 0 to 100% in just 1.4 hours.
- You want a power bank that can also charge a MacBook or laptop at full 100W speed through the USB-C port.
β Who Should Skip All of These?
If you only drive a small sedan or compact car and never need to jump-start big diesel engines, you’re probably overpaying for power you won’t use. A smaller 2000A or 3000A jump starter without an air compressor would save you money and take up less trunk space.
For the most common buyer β someone with a full-size pickup or SUV who wants one tool that does it all β my pick is the GOOLOO A7. The 6000A peak power, 24,000mAh battery, and inflate/deflate air pump cover just about every heavy duty situation you’ll run into.
Frequently Asked Questions
Which is better for heavy duty diesel trucks: the A7 or the GT6000?
For the biggest diesel engines, I’d give the edge to the GT6000 because it’s rated for engines up to 12.0L diesel, while the A7 is rated up to 10L. Both deliver 6000A peak, so they’re very close in raw starting power. But the GT6000 also has a 27,000mAh battery and 24-month standby, which means it’s ready to go when you need it most.
Is the GOOLOO A7 worth the extra money over the A5?
In my opinion, yes, if you own a heavy duty diesel truck or need more versatility. The A7 gives you 6000A peak versus the A5’s 4000A, a larger 24,000mAh battery versus 20,000mAh, and the ability to both inflate and deflate tires and gear. The A5 is still a great value for gas trucks and SUVs, but the A7’s extra power and features justify the jump for serious heavy duty use.
Does the GT6000 have a tire inflator like the A5 and A7?
No, it does not. The GT6000 is a pure jump starter and power bank β there’s no built-in air compressor. If you need to inflate tires on the go, you’ll have to carry a separate tire inflator. That’s the biggest trade-off for getting the 100W bi-directional fast charging and the largest 27,000mAh battery in this lineup.
Which model has the fastest recharge time?
The GT6000 wins this hands down with its 100W bi-directional charging that takes the battery from 0 to 100% in just 1.4 hours. The A5 has a 45W USB-C cable, and the A7 has 30W fast charging β both will take significantly longer to fully recharge. If you’re the type who forgets to charge your gear until the night before a trip, the GT6000 is your best friend.
Can the A5 handle a large diesel pickup truck?
The A5 is rated for all gas engines and up to 10.0L diesel, so it can handle many diesel pickups. But I’d be cautious with the biggest heavy duty diesels like a Ford F-450 or Ram 3500 with a larger displacement engine. For those, I’d step up to the A7 or GT6000 with their 6000A peak for a more comfortable starting margin.
Which model is the most compact and portable?
The A5 is the smallest and lightest of the three at 8.98 x 5.55 x 2.40 inches and 3.2 pounds. The GT6000 is thinner at 1.49 inches wide but longer, and the A7 is the bulkiest at 9.25 x 4.9 x 4.4 inches and 4 pounds. The A5 is the best choice if trunk space is tight and you want a single unit that does jump starting and tire inflation.
My Final Verdict
After comparing every spec, the GOOLOO A7 is my overall winner for heavy duty use. It delivers 6000A peak power for the biggest diesel engines, packs a 24,000mAh battery, and includes both inflate and deflate capabilities β no other model here matches that versatility. The runner-up GT6000 is best if you prioritize 100W fast charging and don’t need an air compressor, while the A5 remains a solid value for gas trucks and SUVs.
If you’re still on the fence, ask yourself this: do you need a built-in tire inflator? If yes, the A7 is your only choice at this power level. If you want the fastest recharge possible and carry a separate inflator, grab the GT6000. Either way, you’re getting a quality jump starter.
