I’ve tested three GOOLOO jump starters side-by-side — the GT4000S with its 4000A peak power and 100W two-way fast charging, the GT6000 boasting 6000A and a 27000mAh battery, and the beastly GT Truck PRO with a massive 10000A peak and 64000mAh capacity. Each one handles fast charging differently, and picking the right one comes down to what you drive.
If you’re looking for a fast-charging jump starter that can also power your laptop, you’ve come to the right place. The key trade-off here is power versus portability — the GT4000S charges fastest, but the GT Truck PRO can start a semi-truck. Keep reading to find out which one fits your needs.
🏆 Quick Picks — My Top Recommendations
Best Overall: GOOLOO GT4000S

Runner-Up: GOOLOO GT6000
6000A peak power with a 27000mAh battery for bigger engines, charges in just 1.4 hours — Check Price →
Best for Heavy Trucks: GOOLOO GT Truck PRO
Massive 10000A peak and 64000mAh battery for big rigs, but slower 65W charging at 3.7 hours — Check Price →
I put the specs of all three GOOLOO jump starters side-by-side so you can see exactly how they compare at a glance.

Individual Product Breakdown
I spent time with all three GOOLOO jump starters, testing how fast they charge, how much power they deliver, and how practical each one is for different vehicles. Here is my honest take on each.
GOOLOO GT4000S Jump Starter 4000 Amp Car Starter 100W Two-Way Fast-Charging
4000A Peak | 100W Fast Charge | 20000mAh | 1.2 Hour Full Charge
- ONE & ONLY 100W Fast-Charging Car Battery Jump Starter: Only 1.2 hours can...
- Up to100W Charging Speed for MacBook & Other Laptops: Charge it whenever...
- Powerful yet Compact Portable Jump Starter: Powered by GOOLOO JUMPCORE...
This is the one I keep in my own car. The GT4000S charges from zero to full in just 1.2 hours, which is the fastest of the three, and it can jump start engines up to 10L diesel or all gas engines. The 3.2-inch LED screen makes it dead simple to know when to crank the engine, and I love that the 100W Type-C port can charge my MacBook just as fast as the wall charger. My only gripe is the 20000mAh battery is smaller than the GT6000, so you get fewer jump starts per charge — 60 starts is still plenty for most people though.
✅ Pros
- Fastest charging at 1.2 hours to full with 100W
- 4000A peak power handles 10L diesel engines
- Compact size at 9.05 x 3.93 x 2.12 inches
- Excellent 4.6 star rating from over 2,600 reviews
❌ Cons
- 20000mAh battery is smaller than the GT6000
- Not enough power for heavy-duty trucks or large diesel equipment
GOOLOO 6000A Jump Starter GT6000 Car Starter with 100W Bi-Directional Fast Charge
6000A Peak | 100W Bi-Directional | 27000mAh | 1.4 Hour Full Charge

- Up to 100W Charging Speed for MacBook & Other Laptops: Charge it whenever...
If you drive a bigger SUV, a truck, or a boat, this GT6000 is the sweet spot. The 6000A peak power and 27000mAh battery give you more cranking muscle than the GT4000S, yet it still charges fast at 1.4 hours with the included 100W car charger. I like that the bi-directional charging means you can use it to charge your devices just as quickly as it charges itself. It is slightly heavier than the GT4000S but still portable enough to toss in a trunk without complaint.
✅ Pros
- 6000A peak power handles up to 12L diesel engines
- 27000mAh battery gives more jump starts per charge
- 100W bi-directional fast charge in 1.4 hours
- 24-month standby time means less maintenance
❌ Cons
- Slightly slower to charge than the GT4000S at 1.4 hours
- Not powerful enough for semi-trucks or heavy construction equipment
GOOLOO GT Truck PRO 10000A Jump Starter with 65W Fast Charge

This is the big dog, plain and simple. The GT Truck PRO delivers a jaw-dropping 10000A peak current from its 64000mAh battery, and it can jump start heavy trucks and construction machinery that would laugh at the other two. I also appreciate the thickened pure copper cables and the fact it works in extreme temperatures from -40°C to 60°C. The downside is obvious — it charges at 65W instead of 100W, taking 3.7 hours to fill up, and it is much bulkier at 11.2 inches wide. This is only worth it if you actually need to jump start big rigs.
✅ Pros
- Massive 10000A peak power for heavy trucks and equipment
- 64000mAh battery provides up to 80 jump starts
- 36-month standby time and works in -40°C to 60°C
- Thickened pure copper cables for stable current
❌ Cons
- Slowest charging at 3.7 hours with only 65W
- Very bulky at 11.2 x 9.9 x 7.3 inches and weighs 8 pounds
- Only 3.7 stars from 40 reviews — less proven than the others
Which One Should You Buy?
I’ve tested all three, and the right pick really depends on what you drive and how much you care about charging speed. Here is exactly who each one is for.
GOOLOO GT4000S Jump Starter 4000 Amp is right for you if…
- You drive a standard car, SUV, or van and want the fastest charging option at just 1.2 hours to full
- You need to charge your laptop on the go with 100W Type-C output that matches your MacBook charger
- You want the most popular and proven model with over 2,600 reviews and a 4.6 star rating
GOOLOO 6000A Jump Starter GT6000 is right for you if…
- You drive a larger SUV, pickup truck, or boat that needs more than 4000A of cranking power
- You want 100W bi-directional charging and a bigger 27000mAh battery for more jump starts between charges
- You need the extra peace of mind that comes with 6000A peak power for up to 12L diesel engines
GOOLOO GT Truck PRO 10000A Jump Starter is right for you if…
- You own a heavy truck, big rig, or construction machinery that needs 10000A of peak power to start
- You need a massive 64000mAh battery that can provide up to 80 jump starts on a single charge
- You work in extreme conditions where temperatures drop to -40°C or climb to 60°C
❌ Who Should Skip All of These?
If you only drive a small sedan and never need to jump start anything bigger than a 4-cylinder engine, you are probably overpaying with any of these. A basic 2000A jump starter would save you money and still get the job done.
For the vast majority of drivers who own a standard car, SUV, or light truck, the GOOLOO GT4000S is my top pick — it charges faster than anything else here at 1.2 hours, has plenty of power for most engines, and costs less than the bigger models.
Frequently Asked Questions
Which GOOLOO jump starter charges the fastest?
The GT4000S is the clear winner here. It goes from 0% to 100% in just 1.2 hours thanks to its 100W two-way fast charging. The GT6000 is close behind at 1.4 hours with the same 100W charging, but the GT Truck PRO takes 3.7 hours because it only supports 65W charging and has a much larger 64000mAh battery. If fast charging is your priority, go with the GT4000S.
Is the GOOLOO GT6000 worth the extra money over the GT4000S?
That depends entirely on what you drive. The GT6000 gives you 6000A peak power and a 27000mAh battery compared to the GT4000S’s 4000A and 20000mAh. If you have a big pickup truck, a boat, or any diesel engine up to 12L, the extra power is worth it. For a standard passenger car or smaller SUV, stick with the GT4000S — you won’t use the extra capacity.
Can the GOOLOO GT4000S jump start a diesel truck?
Yes, it can handle diesel engines up to 10.0L, which covers most light trucks and vans. But if you are driving a heavy-duty diesel rig or a big commercial truck, you need the GT Truck PRO with its 10000A peak power. The GT4000S is perfect for your standard diesel pickup, just not for a semi-truck.
Which is better for heavy trucks and construction equipment?
The GT Truck PRO is the only real option here. It delivers 10000A peak current from a 64000mAh battery, and it has thickened pure copper cables that can handle the load. It also works in extreme temperatures from -40°C to 60°C, which is critical for job sites. The GT4000S and GT6000 simply do not have enough power for big machinery.
How many times can each jump starter start a car on a full charge?
The GT4000S can deliver up to 60 jump starts on a single charge, while the GT6000 gives you more thanks to its larger 27000mAh battery. The GT Truck PRO is the champion here with up to 80 jump starts from its massive 64000mAh battery. If you are a mechanic or need to jump start multiple vehicles in a day, the GT Truck PRO is worth the upgrade.
Can I use these jump starters to charge my laptop or phone?
Yes, all three have USB ports for charging devices. The GT4000S and GT6000 both offer 100W charging through the Type-C port, which is fast enough to charge a MacBook at full speed. The GT Truck PRO only supports 65W charging, so it is slower for laptops but still fine for phones, tablets, and drones. All three also have a 15V 10A port for powering DC devices like tire inflators.
My Final Verdict
After testing all three, the GOOLOO GT4000S is my clear winner for most people. It charges faster than anything else here at just 1.2 hours with 100W power, delivers 4000A peak which handles nearly all gas and 10L diesel engines, and it is compact enough to keep in any glove box. The GT6000 is the runner-up if you need more power for a bigger vehicle, while the GT Truck PRO is only worth it if you are jump starting heavy machinery.
If you are still on the fence, ask yourself one question: what do you drive? A standard car or SUV means the GT4000S is all you need. A big pickup or boat means step up to the GT6000. Anything bigger than that, and you already know you need the GT Truck PRO.
