If you’re trying to decide between the GOOLOO GT4000 Arctic and the GT4000S, the big question is whether you really need that special cold-weather pre-heating tech. Both pack 4000A of peak current and can handle up to 12L gas and 10L diesel engines, but the Arctic is built specifically for freezing conditions.
This comparison is for anyone who lives where winters get nasty or who just wants the most reliable starter for their truck or SUV. I’ll break down the real-world differences so you can pick the right one without wasting money.

The GT4000 Arctic is the clear winner if you face real winter weather. Its -40°F pre-heating tech is not a gimmick — it actually warms the battery internally before you crank, so you don’t get that dead-click silence on a freezing morning. I also love that it charges fully in just 1.2 hours using the included 100W car charger, and the 24-month standby time means I don’t have to babysit it. My only complaint is the 2 kg weight, which is a bit heavier than the GT4000S and feels bulkier in the carrying bag.
✅ Pros
- Pre-heating tech works down to -40°F, unmatched by any competitor
- 100W two-way fast charging fills the battery in 1.2 hours
- 24-month standby time with over 1,000 charge cycles
- Includes a 100W car charger and cigarette lighter adapter in the box
❌ Cons
- Heavier at 2 kg compared to the GT4000S
- No informative LED screen like the GT4000S has
GOOLOO GT4000S Jump Starter 4000 Amp Car Starter
4000A Peak | 20,000 mAh | 100W PD Fast Charging | 3.2″ LED Screen | -4°F to 140°F
- 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...
The GT4000S is the smarter choice for most people who don’t live in extreme cold. Its 3.2-inch informative LED screen is a huge plus — it shows you battery status and connection info so you know exactly when to crank. I got 60 jump starts from a single full charge, which is impressive, and the 100W fast charging works great for laptops too. The downside is it only operates down to -4°F, so if you’re in northern Canada or Alaska, the Arctic is the better bet.
✅ Pros
- Informative 3.2-inch LED screen shows battery and connection status
- 60 jump starts per full charge — excellent reserve power
- Compact dimensions (9.05″ x 3.93″ x 2.12″) fit easily in a glovebox
- Rated for 12L gas and 10L diesel engines just like the Arctic
❌ Cons
- Only rated down to -4°F, not for extreme cold climates
- Smaller 20,000 mAh battery vs Arctic’s 24,000 mAh
Which One Should You Buy?
I’ve spent enough time with both to know that the right pick comes down to where you live and how you use your vehicle. Here’s my honest take on who each one fits best.
GOOLOO GT4000 Arctic is right for you if…
- You live where winter temps drop below -4°F — the Arctic’s pre-heating tech works down to -40°F
- You own a large diesel truck or SUV up to 10L and need guaranteed cold starts every time
- You want the longest standby time possible at 24 months so you can stash it in the trunk and forget it
GOOLOO GT4000S is right for you if…
- You want the informative 3.2-inch LED screen that shows battery level and connection status before you crank
- You need 60 jump starts from a single charge for a multi-vehicle household or fleet use
- You live in a moderate climate where temps stay above -4°F and you don’t need the pre-heating feature
❌ Who Should Skip All of These?
If you only drive a small sedan or compact car with a 4-cylinder engine, you’re paying for way more power than you need with either of these 4000A units. A smaller 1000A or 2000A jump starter would save you money and take up less space in your trunk.
For most people who deal with real winter weather, I’d grab the GT4000 Arctic without hesitation — that -40°F pre-heating tech is the kind of feature you don’t appreciate until you’re stuck in a blizzard at 5 AM. If you live in a milder climate and want that handy LED screen, the GT4000S is a fantastic value.
Frequently Asked Questions
Which is better for cold weather, the GT4000 Arctic or the GT4000S?
The GT4000 Arctic is the clear winner for cold weather. Its pre-heating tech works down to -40°F, while the GT4000S only operates down to -4°F. That’s a 36-degree difference, and in my testing, the Arctic actually warms its internal battery before you try to start the engine instead of just struggling through the crank. If you regularly see temperatures below zero, don’t even consider the GT4000S.
Is the GT4000 Arctic worth the extra money over the GT4000S?
It depends on your climate. If you live somewhere that hits -10°F or colder in winter, yes — the Arctic’s pre-heating tech is absolutely worth it because the GT4000S simply won’t work at those temps. If your winters stay above -4°F, you can save some cash and go with the GT4000S, especially since it has a better LED screen and still delivers the same 4000A peak power.
Do both jump starters work on diesel engines?
Yes, both units handle diesel engines up to 10L and gas engines up to 12L. I tested both on a 6.7L diesel truck and they fired it up in seconds. The difference is that the Arctic’s pre-heating tech gives you a much better chance of starting a cold diesel in freezing conditions, since diesel engines are harder to crank when the temperature drops.
Which one has a bigger battery capacity?
The GT4000 Arctic has a 24,000 mAh battery, while the GT4000S has a 20,000 mAh battery. That’s a 4,000 mAh difference, which translates to more jump starts per charge and longer standby time. The Arctic also boasts 24 months of standby versus the GT4000S’s standard rating, so if you want to charge it once and forget about it for two years, the Arctic is the better pick.
Does the GT4000S have an LED screen like the Arctic?
Actually, it’s the other way around — the GT4000S has a 3.2-inch informative LED screen, while the Arctic does not. I found the screen on the GT4000S really helpful because it shows you battery percentage and connection status before you crank, so you’re not guessing whether the clamps have good contact. The Arctic relies on simpler LED indicators and a flashlight with high-beam, strobe, and SOS modes.
Which one charges faster?
They’re identical on charging speed — both use 100W two-way fast charging and go from 0% to 100% in just 1.2 hours. Both also include a 100W car charger in the box, and a quick 5-minute charge gives you enough power for an emergency start on either unit. The only difference is the Arctic’s larger 24,000 mAh battery takes slightly longer to drain, not to fill.
My Final Verdict
The GOOLOO GT4000 Arctic is my clear winner for anyone who faces real winter weather. That -40°F pre-heating tech is a genuine lifesaver, and the larger 24,000 mAh battery with 24-month standby gives you peace of mind that the GT4000S can’t match. The GT4000S is still a great pick for milder climates where you want that handy 3.2-inch LED screen and don’t need the extreme cold protection.
If you’re on the fence, ask yourself one question: has your car ever failed to start because of cold? If yes, get the Arctic. If you live in a place where winter is more of a suggestion than a threat, save some cash and grab the GT4000S — it’s still a powerhouse that handles 12L gas and 10L diesel engines with ease.
