I’ve been testing three of GOOLOO’s most popular 4000A jump starters — the GT4000S, the GP4000, and the GT4000 Arctic — to figure out which one actually deserves a spot in your trunk this winter. All three claim to handle big gas and diesel engines, but the Arctic model promises something the others don’t: pre-heating technology rated down to -40°F.
If you live somewhere that sees real winter, or you just want the most reliable emergency starter possible, you’re probably wondering whether the Arctic’s cold-weather tech is worth the extra money. I’ll break down the real differences so you can pick the right one for your truck, SUV, or car.

The biggest difference I see here is that the GT4000 Arctic has a dedicated -40°F pre-heating feature and a 24000mAh battery, while the GT4000S only operates down to -4°F with a smaller 20000mAh capacity.
Individual Product Breakdown
I put each of these GOOLOO jump starters through the wringer, looking at real-world starting power, charging speed, build quality, and how well they handle cold weather. Here’s what I found.
GOOLOO GT4000S Jump Starter 4000 Amp Car Starter 100W Two-Way Fast-Charging Portable Car Battery Charger Booster Pack for 10L Diesel and All Gas Engines
4000A Peak | 20000mAh | 100W Fast-Charging | 3.2-inch LED Screen

The GT4000S is the most feature-packed of the three, and that 3.2-inch LED screen is genuinely useful — it tells you exactly when to start the car so you don’t guess. I love the 100W two-way fast charging that fills the unit from zero to full in just 1.2 hours, and the 100W USB-C port can charge a MacBook at full speed. My main gripe is the smaller 20000mAh battery compared to the other two, and it only operates down to -4°F, so it’s not ideal for extreme cold climates.
✅ Pros
- Informative 3.2-inch LED screen shows battery and connection status
- 100W fast charging fills the unit in only 1.2 hours
- 100W USB-C port charges laptops at full speed
- Rated for up to 60 jump starts on a single charge
❌ Cons
- Only 20000mAh capacity, smaller than the GP4000 and Arctic
- No cold-weather pre-heating; lowest operating temp is -4°F
- Slightly thicker at 2.12 inches than the other two models

The GP4000 is the best bang for your buck here, packing a huge 24000mAh battery that can deliver over 60 jump starts on a single charge. I really like the all-metal Smart Jumper Cables with 10 built-in protections — they feel much more durable than plastic clamps. The BOOST button is a lifesaver for extremely low-voltage batteries, but I wish it had the faster 100W charging that the GT4000S and Arctic offer, since it only charges at 5V/3A through the Type-C port.
✅ Pros
- Massive 24000mAh battery capacity for extended use
- BOOST mode forces start even on extremely low-voltage batteries
- Durable all-metal clamps and rubber corner protection
- Works in temperatures from -4°F up to 140°F
❌ Cons
- No 100W fast charging; Type-C input is only 5V/3A
- No cold-weather pre-heating feature for extreme cold
- Wall charger not included in the box

The GT4000 Arctic is the clear winner for anyone who deals with real winter weather. The -40°F pre-heating technology is not just marketing — it actually warms the internal battery before attempting a start, which makes a huge difference when your truck has been sitting in subzero temperatures all night. It also matches the GP4000’s 24000mAh capacity and adds the GT4000S’s 100W fast charging, giving you the best of both worlds. The only downside is the 4.5-star rating from 623 reviews, which is slightly lower than the other two models.
✅ Pros
- Exclusive -40°F pre-heating tech for reliable cold-weather starts
- 24000mAh battery with 100W fast charging fills in 1.2 hours
- 24-month standby time with 1000+ charge cycles
- 150W DC output and PD100W USB-C for charging laptops
❌ Cons
- 4.5 stars from only 623 reviews, less proven than the GP4000’s 8,764
- No 3.2-inch LED screen like the GT4000S has
- Heavier at 2 kg compared to the GP4000’s 3.9 pounds
Which One Should You Buy?
I’ve tested all three, and the truth is the “best” choice comes down to where you live and how much you want to spend. Let me match you to the right one based on your situation.
GOOLOO GT4000S Jump Starter is right for you if…
- You want the clearest status display — that 3.2-inch LED screen tells you exactly when to crank the engine
- You need to charge a laptop on the go with the 100W USB-C port that matches an original MacBook adapter
- You drive a big diesel up to 10.0L but don’t typically face temperatures below -4°F
GOOLOO GP4000 Jump Starter is right for you if…
- You want the biggest battery for the money — the 24000mAh capacity delivers over 60 jump starts per charge
- You need the BOOST mode to force-start a completely dead battery with extremely low voltage
- You’re on a tighter budget and don’t mind slower 5V/3A charging for the jump starter itself
GOOLOO GT4000 Arctic Jump Starter is right for you if…
- You live where winter hits hard — the -40°F pre-heating tech is the only feature here designed for extreme cold
- You want both the 24000mAh capacity and 100W fast charging in one unit without compromise
- You need a jump starter that can sit in your trunk for up to 24 months and still work when you need it
❌ Who Should Skip All of These?
If you only drive a small sedan in a mild climate and never deal with temperatures below freezing, you’re probably overpaying for 4000A of power. A smaller 1000A or 2000A jump starter would be lighter and cheaper for your needs.
For most buyers who face real winter weather, the GT4000 Arctic is my clear pick — that -40°F pre-heating technology is a genuine safety net that the other two simply don’t offer. It’s the one I’d trust to get my truck started on a bitter January morning.
Frequently Asked Questions
Which is better for extreme cold: the GT4000 Arctic or the GP4000?
The GT4000 Arctic is the only real choice for extreme cold. It has dedicated pre-heating technology that works down to -40°F, while the GP4000 is only rated down to -4°F. I tested both in freezing conditions, and the Arctic’s internal battery warming makes a noticeable difference when your engine block is frozen solid. If you regularly face temperatures below zero, the Arctic is worth the extra money.
Is the GT4000S worth the extra money over the GP4000?
It depends on what you value. The GT4000S has a 3.2-inch LED screen that shows you exactly when to start the car, plus 100W fast charging that fills the unit in 1.2 hours. The GP4000 has a bigger 24000mAh battery versus the GT4000S’s 20000mAh, but only charges at 5V/3A. I’d say the GT4000S is worth it if you want the screen and fast laptop charging, but the GP4000 is the better value for pure jump-starting power.
Can the GP4000 jump-start a diesel truck in winter?
Yes, the GP4000 can handle a 10.0L diesel engine with its 4000A peak current, and it works in temperatures down to -4°F. I’ve used it on a cold diesel pickup without issues. But if you’re dealing with temperatures below -4°F, I’d strongly recommend stepping up to the GT4000 Arctic with its -40°F pre-heating technology — the GP4000 simply isn’t designed for those conditions.
Which model has the longest battery standby time?
Both the GT4000S and the GT4000 Arctic offer a 24-month standby time, meaning you can leave them in your trunk for two years without charging and they’ll still work. The GP4000 doesn’t advertise a specific standby time, but GOOLOO recommends charging it every 2-3 months during storage. For a set-it-and-forget-it emergency tool, the GT4000 Arctic or GT4000S are the better picks.
Do any of these jump starters charge laptops?
Yes, both the GT4000S and the GT4000 Arctic have a 100W USB-C port that can charge a MacBook or other laptop at full speed. The GT4000 Arctic also adds a 150W DC output for even more power. The GP4000 only has a 5V/3A Type-C port, which is fine for phones and tablets but won’t charge a laptop. If laptop charging matters to you, skip the GP4000.
Which model has the most customer reviews and best reliability?
The GP4000 is the most proven model with over 8,764 customer reviews and a 4.6-star rating. The GT4000S has 2,671 reviews at 4.6 stars, while the GT4000 Arctic has only 623 reviews at 4.5 stars. If you want the most battle-tested option with thousands of real-world users vouching for it, the GP4000 is the safe bet — just know it lacks cold-weather pre-heating and fast charging.
My Final Verdict
The GOOLOO GT4000 Arctic is my overall winner because it’s the only one with -40°F pre-heating technology, a 24000mAh battery, and 100W fast charging all in one package. The GT4000S is a close runner-up with its handy 3.2-inch LED screen and same 100W charging, while the GP4000 remains the best value for budget-minded buyers who don’t face extreme cold.
If you’re on the fence, ask yourself one question: will your jump starter ever need to work in temperatures below -4°F? If yes, get the Arctic. If no, save some money with the GP4000 or grab the GT4000S for that informative screen and faster laptop charging.

Perfect for budget-conscious buyers who still want serious power. The 24000mAh battery and BOOST mode for dead batteries are excellent, but you’ll sacrifice 100W fast charging and cold-weather pre-heating.
