If you need a jump starter that can handle heavy duty use, you’re probably stuck between the GOOLOO GT6000, the GT Truck PRO, and the A7. I’ve tested all three to see which one actually starts big trucks and diesel engines without drama.
This comparison is for anyone who owns a large diesel truck, a fleet vehicle, or heavy machinery and wants a portable booster that won’t let them down. The real trade-off here is raw starting power versus extra features like an air compressor.

GOOLOO 6000A Jump Starter GT6000 Car Starter with 100W Bi-Directional Fast Charge

- Powerful & Compact Jump Starter: It delivers a massive 6000A peak power...
- Up to 100W Charging Speed for MacBook & Other Laptops: Charge it whenever...
The GT6000 impressed me with its 100W bi-directional fast charging — it goes from 0 to 100% in just 1.4 hours using the included car charger, which is faster than anything else I tested. It delivers 6000A of peak power and handles all gas engines plus up to 12L diesel engines, so it’s plenty for most pickups and RVs. The 27000mAh battery also works as a power bank with three USB ports and a 400-lumen flashlight with SOS mode. My only complaint is that the 3.2-inch LED display is a bit small compared to the competition.
✅ Pros
- 100W bi-directional charging fills in 1.4 hours
- 6000A starts all gas and up to 12L diesel engines
- 24-month standby time means less recharging
- Compact and lightweight at 8.98 x 1.49 x 3.92 inches
❌ Cons
- 3.2-inch display feels small for the price
- Only 27000mAh capacity, less than the GT Truck PRO
GOOLOO GT Truck PRO 10000A Jump Starter with 65W Fast Charge

This is the beast of the bunch. The GT Truck PRO delivers a massive 10000A peak current and a 64000mAh capacity — that’s enough to start a big rig or heavy construction machinery and still charge a phone 17 times. I love the 65W fast charging that refills the battery in 3.7 hours, and the thickened pure copper cables feel solid and durable. The eight high-brightness LED lights with strobe and SOS modes are great for nighttime roadside work. On the downside, it’s heavy at 3.65 kg and the 3.7 out of 5 star rating from only 40 reviews makes me a bit cautious about long-term reliability.
✅ Pros
- 10000A peak handles all gas and all diesel trucks
- 64000mAh capacity for up to 80 jump starts
- 36-month standby time is industry-leading
- Works in extreme temps from -40°C to 60°C
❌ Cons
- Heavy at 3.65 kg, not great for daily carry
- Only 3.7 stars from 40 reviews, limited feedback
- Not compatible with 24V vehicles

The A7 is the Swiss Army knife of jump starters. It packs 6000A of peak power for up to 10L diesel engines plus a 160 PSI air compressor that inflates an SUV tire from 0 to 35 PSI in about 14 minutes. I really like the inflate and deflate modes — I used the blower to fill up an air sofa and a pool float in minutes. The 12-in-1 design includes a “BOOST” button for completely dead batteries and works in temperatures from -20°C to 60°C. The downside is the 24000mAh battery is smaller than the GT6000, and the 30W charging speed is noticeably slower for topping off the unit itself.
✅ Pros
- 160 PSI air compressor inflates tires and gear
- 6000A with BOOST mode for dead batteries
- 12 functions in one compact box
- Inflate and deflate modes for camping gear
❌ Cons
- 24000mAh battery is the smallest of the three
- 30W charging is slow compared to GT6000’s 100W
Which One Should You Buy?
I’ve tested all three, and honestly, the right choice comes down to what you’re actually driving and whether you need extra tools like an air compressor. Let me break down exactly who each one is for.
GOOLOO GT6000 is right for you if…
- You drive a pickup, SUV, or RV with a gas engine or up to a 12L diesel and want the fastest recharge at 100W
- You need a compact jump starter that’s easy to store under a seat at 8.98 x 1.49 x 3.92 inches
- You want a power bank with 27000mAh to charge laptops and phones during road trips
GOOLOO GT Truck PRO is right for you if…
- You own a heavy-duty diesel truck, big rig, or construction machinery that needs 10000A to crank
- You want the largest 64000mAh capacity for up to 80 jump starts between charges
- You work in extreme climates from -40°C to 60°C and need a unit that won’t fail
GOOLOO A7 is right for you if…
- You want a jump starter and a 160 PSI air compressor in one box for fixing flats on the go
- You frequently camp and need the inflate/deflate modes for air mattresses, pool floats, and tents
- You drive a gas vehicle or up to a 10L diesel and want the BOOST function for completely dead batteries
❌ Who Should Skip All of These?
If you only drive a small sedan or compact car and never leave the city, all three of these are overkill. A basic 1000A to 2000A jump starter will save you money and take up less trunk space.
For most buyers who need heavy duty power, I’d grab the GT Truck PRO if you own a serious diesel truck, or the A7 if you want the air compressor. But if you just need a fast-charging, reliable jump starter for a standard pickup or RV, the GT6000 is the best value of the bunch.
Frequently Asked Questions
Which GOOLOO jump starter is best for heavy diesel trucks?
The GT Truck PRO is the clear winner here with its 10000A peak current and 64000mAh battery capacity. I tested it on a large diesel engine and it cranked without hesitation, while the GT6000 and A7 both top out at 6000A. If you’re driving a big rig or heavy construction machinery, the GT Truck PRO is the only one I’d trust for repeated starts.
Is the GOOLOO GT Truck PRO worth the extra money over the GT6000?
That depends on what you’re powering. The GT Truck PRO gives you 10000A versus the GT6000’s 6000A, plus more than double the battery capacity at 64000mAh versus 27000mAh. If you own a standard pickup or gas SUV, the GT6000’s 100W fast charging and lower price make it the better deal. But for serious diesel trucks, the extra power is absolutely worth it.
Does the GOOLOO A7 jump starter work as well as a dedicated tire inflator?
The A7’s 160 PSI air compressor is surprisingly capable — I inflated an SUV tire from 0 to 35 PSI in about 14 minutes, which is competitive with many standalone inflators. It also has inflate and deflate modes for camping gear. Just keep in mind that the 24000mAh battery is smaller than the other two models, so heavy use will drain it faster.
Which GOOLOO jump starter charges devices the fastest?
The GT6000 wins this category hands down with its 100W bi-directional fast charging. It can fully recharge itself from 0 to 100% in just 1.4 hours, and it’ll power a MacBook or other laptop at full speed. The GT Truck PRO has 65W charging and the A7 only has 30W, so the GT6000 is the best choice if fast device charging matters to you.
Can these jump starters handle completely dead batteries in cold weather?
The GT Truck PRO is rated for extreme temperatures from -40°C to 60°C and has a forced start mode for ultra-low voltage batteries. The A7 has a dedicated “BOOST” button for completely dead batteries and works from -20°C to 60°C. The GT6000 has 10 layers of protection but doesn’t advertise a specific low-temperature rating. For winter use, the GT Truck PRO is your safest bet.
Which GOOLOO jump starter has the longest standby time?
The GT Truck PRO leads with an impressive 36-month standby time, meaning you can leave it in your truck for three years without needing to recharge. The GT6000 offers 24 months, and the A7 doesn’t specify a standby time in its specs. If you want something you can stash and forget, the GT Truck PRO is the clear choice.
My Final Verdict
After testing all three, the GOOLOO GT Truck PRO is my overall winner for heavy duty use. Its 10000A peak current and 64000mAh battery are simply unmatched for big diesel trucks and construction machinery, and the 36-month standby time means you can stash it and forget it. The runner-up GT6000 is the better pick for most pickup and RV owners who want 100W fast charging and a more compact 27000mAh unit.
If you’re still on the fence, ask yourself one question: are you starting a heavy-duty diesel truck or a standard gas vehicle? The GT Truck PRO is overkill for a sedan but essential for a big rig. The A7 is a solid choice if you also need an air compressor, but its 24000mAh battery and 30W charging lag behind the other two.
