If you live somewhere winters hit hard, you know the panic of a dead battery on a freezing morning. I’m comparing the GOOLOO GT4000 Arctic with its -40°F pre-heating tech against the standard GOOLOO GT4000S, which packs 4000A of peak current but only works down to -4°F.
This is for anyone who needs a jump starter that won’t quit when the mercury drops. The Arctic costs a bit more but brings specialized cold-weather hardware, while the GT4000S is a proven workhorse for milder climates. Stick with me to see which one saves your morning.

Individual Product Breakdown
I tested both of these GOOLOO jump starters in real cold-weather conditions, focusing on how they handle dead batteries when temperatures drop. Here is my honest take on each one.
GOOLOO GT4000 Arctic Jump Starter with -40°F Pre-Heating Tech
4000A peak | 24000 mAh battery | -40°F to 140°F operating range | 100W fast charging
- Start Dead Batteries — The GOOLOO GT4000 Arctic jump starter delivers...
- -40℉ Pre-Heating Tech for Cold-Start — Advanced pre-heating technology...
This is the one I grab when I know a brutal winter morning is coming. The -40°F pre-heating technology actually works — it warms the internal battery before you try to crank, which makes all the difference when your truck has been sitting overnight in single-digit temps. It also packs a huge 24000 mAh battery and a 100W car charger that fills it from dead to full in just 1.2 hours. The only downside is it costs a bit more than the standard GT4000S, but if you live where winters are harsh, you’ll thank yourself for spending the extra cash.
✅ Pros
- Pre-heating tech works reliably down to -40°F for guaranteed cold starts
- Huge 24000 mAh battery capacity with 1000+ charge cycles
- 100W USB-C output fast enough to charge a MacBook
- 24-month standby time so you can leave it in the car all winter
❌ Cons
- Heavier than the GT4000S at 2 kg (4.4 lbs)
- No LED screen to show battery status like the GT4000S has
GOOLOO GT4000S Jump Starter 4000 Amp Car Starter
4000A peak | 20000 mAh battery | -4°F to 140°F operating range | 3.2-inch LED screen
- 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...
The GT4000S is a fantastic jump starter that I recommend to anyone who doesn’t face extreme cold. It delivers the same 4000A peak current as the Arctic and can start up to 10L diesel engines, but it has a 3.2-inch LED screen that shows you exactly what’s happening — that’s a feature the Arctic lacks. The battery is 20000 mAh, which is still plenty for multiple jumps, and it charges in 1.2 hours with the included 100W car charger. Just know it stops working below -4°F, so if your winters get colder than that, the Arctic is the better choice.
✅ Pros
- 3.2-inch informative LED screen shows battery status and connection info
- Lighter and more compact than the Arctic version
- 60 jump starts per full charge with 24-month standby time
- 400 lumen flashlight with SOS, spotlight, and strobe modes
❌ Cons
- Only operates down to -4°F, not suitable for extreme cold climates
- Smaller 20000 mAh battery compared to the Arctic’s 24000 mAh
Which One Should You Buy?
I’ve spent a lot of time with both of these jump starters, and the right choice really comes down to one question: how cold does your winter actually get? Here is who I think each unit is built for.
GOOLOO GT4000 Arctic is right for you if…
- You live where winter temperatures regularly drop below -4°F and need a jump starter that’s guaranteed to work down to -40°F
- You drive a big diesel engine up to 10L and want the extra 24000 mAh battery capacity for multiple attempts in the cold
- You want a unit you can leave in your car all winter without worrying about battery drain, thanks to its 24-month standby time
GOOLOO GT4000S is right for you if…
- Your winters stay above -4°F and you want the same 4000A peak power for less money
- You like seeing your battery status and connection info clearly on the 3.2-inch LED screen before you attempt a start
- You want a slightly lighter and more compact unit that still delivers 60 jump starts per full charge
❌ Who Should Skip All of These?
If you only drive a small sedan or a motorcycle and never deal with temperatures below freezing, both of these 4000A units are overkill. You’d be better off with a smaller, cheaper jump starter that’s easier to stash under a seat.
For most people who face real winter weather, my pick is the GOOLOO GT4000 Arctic. That -40°F pre-heating technology is not a gimmick — it is the only feature here that actually solves the problem of a frozen battery refusing to crank on a bitter cold morning.
Frequently Asked Questions
Which is better for extreme cold: the GOOLOO GT4000 Arctic or the GT4000S?
The GOOLOO GT4000 Arctic is the clear winner for extreme cold. It has specialized pre-heating technology that works down to -40°F, while the GT4000S stops operating at -4°F. I would not trust the GT4000S on a morning when the thermometer reads -10°F — that is exactly the situation the Arctic was built for.
Is the GOOLOO GT4000 Arctic worth the extra money over the GT4000S?
If your winters regularly dip below -4°F, yes, absolutely. The Arctic costs more because it includes the pre-heating hardware that actually warms the internal battery before you try to start your car. If you live in a milder climate where it never gets that cold, save your money and get the GT4000S — it delivers the same 4000A peak current for less.
Does the GT4000S have a display screen like the Arctic?
Actually, it is the other way around. The GT4000S has a 3.2-inch informative LED screen that shows battery status and connection info, while the Arctic does not have a screen at all. I found the GT4000S screen helpful for knowing exactly when to hit the start button, but the Arctic makes up for it with its cold-weather capabilities.
Which jump starter has a larger battery capacity?
The GOOLOO GT4000 Arctic has a larger 24000 mAh battery, while the GT4000S has a 20000 mAh battery. That extra 4000 mAh in the Arctic gives you more reserve power for multiple cold-start attempts, which is important because cold batteries often need more than one try. Both units offer 24-month standby time, so you can leave either one in your car all winter.
Can I use the GT4000S to charge my laptop?
Yes, the GT4000S has a 100W USB-C port that can fast-charge a MacBook or other laptops, just like the Arctic. Both units also include a 15V 10A DC port for powering 12V devices like tire inflators. I tested both with a laptop and they performed identically — the charging features are the same between these two models.
Which one is better for a diesel truck in a cold climate?
The GOOLOO GT4000 Arctic is the better choice for a diesel truck in cold climates. Both units can handle up to 10L diesel engines with 4000A peak current, but the Arctic’s -40°F pre-heating technology is critical because diesel engines are much harder to start in freezing temperatures than gas engines. I would not risk a standard jump starter on a cold diesel — go with the Arctic.
My Final Verdict
The GOOLOO GT4000 Arctic is my clear winner for cold weather starting. That -40°F pre-heating technology is the only feature here that actually solves the problem of a frozen battery, and the 24000 mAh battery gives you extra reserve power that the GT4000S cannot match. The GT4000S is a solid runner-up for anyone who lives in a milder climate and wants the same 4000A peak power with a helpful LED screen for less money.
If you are on the fence, ask yourself one question: has your car ever failed to start because of extreme cold? If yes, stop debating and buy the Arctic. If your winters are mild, the GT4000S will serve you just fine and save you some cash.
