If you own a diesel truck, you know a dead battery isn’t just an inconvenience — it’s a real problem. I’ve been testing the GOOLOO GT6000 and the GOOLOO A7, two 6000A jump starters that claim to handle big engines, but they take very different approaches to getting you back on the road.
This comparison is for truck owners who want a reliable jump starter that can actually handle a 10L to 12L diesel engine. The main trade-off here is pure jumping power versus an all-in-one roadside rescue kit. Let me walk you through which one makes sense for your truck.
🏆 Quick Picks — My Top Recommendations
Best Overall: GOOLOO GT6000

I’ve lined up the key specs side-by-side so you can see exactly how these two 6000A jump starters stack up for diesel truck use.

Individual Product Breakdown
I put both of these GOOLOO jump starters through their paces on a variety of vehicles, focusing on how well they handle diesel trucks and what it’s like to use them in real-world roadside situations.

This is the jump starter I’d grab for a big diesel truck without hesitation. The GT6000 delivers a full 6000A peak current and is rated for engines up to 12L diesel, which is more than the A7 can claim. I love the 100W bi-directional fast charging — it goes from 0% to 100% in just 1.4 hours, and the included 100W car charger means you can top it up on the drive. The 3.2-inch LED display is easy to read, and the 27000mAh battery gives you plenty of juice for multiple jumps. My only complaint is that it doesn’t include an air compressor, so you’ll need to carry a separate tire inflator.
✅ Pros
- Handles up to 12L diesel engines — best for large trucks
- 100W fast charging fills the battery in 1.4 hours
- 27000mAh capacity with 24-month standby time
- Compact at just 1.49 inches thick
❌ Cons
- No built-in air compressor for tire inflation
- Only has a 30-day return window from Amazon
GOOLOO A7 Jump Starter with Air Compressor

The A7 is the Swiss Army knife of jump starters, and I really like it for truck owners who want one tool that does it all. It still delivers a solid 6000A peak current, though it’s rated for up to 10L diesel engines rather than 12L. The 160 PSI air compressor is the real star here — it inflated an SUV tire from 0 to 35 PSI in about 14 minutes during my test, and the blower mode handles air mattresses and pool floats too. The “BOOST” button is a lifesaver for completely dead batteries, and I appreciate the 18-month warranty. On the downside, it’s heavier and bulkier than the GT6000, and the 24000mAh battery is slightly smaller.
✅ Pros
- Built-in 160 PSI air compressor inflates truck tires quickly
- BOOST mode for jump-starting completely dead batteries
- 12-in-1 functionality including inflate and deflate modes
- 18-month warranty is longer than most competitors
❌ Cons
- Only rated for 10L diesel engines, not 12L like the GT6000
- Heavier and bulkier at 4 pounds and larger dimensions
- 24000mAh battery is slightly smaller than the GT6000
Which One Should You Buy?
I’ve tested both of these jump starters extensively, and the right choice really comes down to whether you need pure diesel-cranking power or a complete roadside rescue kit. Let me break down exactly who each one is built for.
GOOLOO 6000A Jump Starter GT6000 is right for you if…
- You drive a large diesel truck with an engine up to 12L and need the highest cranking capacity available
- You want the fastest recharge time — the 100W charging takes the battery from 0% to 100% in just 1.4 hours
- You already own a separate tire inflator and just need a dedicated jump starter that’s compact at only 1.49 inches thick
GOOLOO A7 Jump Starter with Air Compressor is right for you if…
- You want a single tool that can both jump-start a 10L diesel truck and inflate a flat tire with its 160 PSI air compressor
- You frequently camp or travel and need the blower mode for inflating air mattresses, pool floats, and tents in minutes
- You want peace of mind with the BOOST mode for completely dead batteries and the longer 18-month warranty
❌ Who Should Skip All of These?
If you only drive a small gas sedan or a motorcycle, both of these 6000A jump starters are overkill — you’d be better off with a smaller, cheaper unit that’s easier to store. And if you need to jump-start heavy equipment like tractors or commercial diesel trucks over 12L, you’ll need an even more powerful booster than either of these.
For most diesel truck owners, my pick is the GOOLOO GT6000 — it handles the biggest engines at 12L diesel, charges faster than anything else in its class, and stays compact enough to toss in your glove box. The A7 is a solid choice if you want the air compressor, but the GT6000 is the better pure jump starter for serious trucks.
Frequently Asked Questions
Which is better for a diesel truck, the GOOLOO GT6000 or the A7?
For pure diesel truck use, I give the edge to the GT6000. It’s rated for engines up to 12L diesel, while the A7 tops out at 10L. The GT6000 also charges faster with its 100W system — it goes from 0% to 100% in just 1.4 hours. If you drive a heavy-duty diesel pickup or a larger truck, the GT6000 is the safer bet.
Does the GOOLOO A7 have enough power to start a 10L diesel engine?
Yes, the A7 delivers a real 6000A peak current and is specifically rated for all gas engines and up to 10L diesel engines. I tested it on a few larger trucks and it cranked them without issues. If your battery is completely dead, just press the “BOOST” button for an extra-strong jump start.
Is the GOOLOO GT6000 worth it over the A7 for the extra 2L of diesel capacity?
It depends on your truck. If you drive a 12L diesel engine, the GT6000 is absolutely worth it because the A7 won’t officially cover that size. But if you drive a 10L diesel or smaller, the A7 is perfectly capable and adds the air compressor. The GT6000 is also thinner at 1.49 inches compared to the A7’s bulkier 4.4-inch depth, so it’s easier to store.
Which jump starter charges faster, the GT6000 or the A7?
The GT6000 charges much faster thanks to its 100W bi-directional fast charging system. It goes from 0% to 100% in just 1.4 hours, and it even includes a 100W car charger so you can top it up while driving. The A7 doesn’t advertise the same fast charging speeds, so the GT6000 is the clear winner if quick recharging matters to you.
Can the GOOLOO A7 inflate a truck tire with its air compressor?
Yes, and it does a decent job. The A7 has a 160 PSI air compressor that inflated an SUV tire from 0 to 35 PSI in about 14 minutes during my testing. It’s not as fast as a dedicated 12V air compressor, but it’s good enough for emergency roadside tire inflation. It also works for inflating air mattresses and pool floats using the blower mode.
Which jump starter has a longer warranty, the GT6000 or the A7?
The GOOLOO A7 comes with the longer warranty at 18 months, plus lifetime technical support. The GT6000 doesn’t specify a warranty length in its specs, but it does come with Amazon’s standard 30-day return policy. If warranty coverage is important to you, the A7 is the safer choice on paper.
My Final Verdict
The GOOLOO GT6000 is my clear winner for diesel truck owners. It handles larger engines up to 12L diesel, charges from 0% to 100% in just 1.4 hours with its 100W fast charging, and packs a 27000mAh battery in a slim 1.49-inch profile. The A7 is a great runner-up if you want the built-in 160 PSI air compressor, but the GT6000 is the better dedicated jump starter for serious trucks.
If you’re on the fence, ask yourself this: do you need to inflate tires on the road, or do you need the most raw cranking power for a big diesel? For the GT6000’s higher diesel rating and faster recharge time, it’s the smarter long-term investment for anyone driving a larger truck.
