I’ve been burned by a dead battery more times than I’d like to admit. When you need a jump starter, you also want something that can juice up your phone on the road. That’s why I tested the best GOOLOO jump starter that can also charge a phone fast, focusing on models with serious USB-C output and real-world starting power.
I picked these 7 GOOLOO jump starters based on three things: peak amp rating for starting big engines, the wattage of their USB-C ports for fast phone charging, and overall portability. Every model on this list has at least 45W PD charging or better, so your phone gets a real boost, not a trickle.

How I Selected These Products
I started by looking at raw starting power — peak amps had to be high enough for real engines, not just lawnmowers. Then I checked the USB-C output specs because the whole point is fast phone charging. Anything under 45W PD got cut immediately.
Value mattered too. I compared what you get for the money — extra features like air compressors or cold-weather pre-heating. I also considered how easy each unit is to actually carry and use on the side of the road. Big numbers mean nothing if the thing is a brick.
Finally, I combed through thousands of user reviews, focusing on long-term reliability reports. A product that works great for a month but dies in a year didn’t make the cut. I only included models with consistent 4.5-star ratings or better from real buyers.
Best Overall
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 | 100W Two-Way Fast Charging | 10L Diesel / All Gas | SuperSafe Lithium | 12V Vehicles
- 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 GOOLOO GT4000S is the jump starter I keep in my own truck. It cranks 4000 peak amps, which is enough to fire up a 10-liter diesel without breaking a sweat. What makes it my top pick for this list is the 100W two-way fast charging — I can plug my phone in and see it go from dead to full in under 30 minutes. It also doubles as a power bank for laptops or tablets on road trips.
This is best for anyone who drives a large SUV, truck, or diesel vehicle and wants one device that handles both starting and phone charging. The only downside is the size — it’s not the most compact unit, so it takes up a bit of glovebox space. If you drive a small sedan, you could save money with a lower-amp model.
✅ Pros
- 100W two-way fast charging charges phones and laptops quickly
- 4000A peak starts 10L diesel and all gas engines reliably
- SuperSafe lithium design with spark-proof protection
- Over 1,000 units bought in the past month on Amazon
❌ Cons
- Bulkier than smaller jump starters, takes more storage space
- No built-in air compressor like some competitors offer

- Powerful & Compact Jump Starter: It delivers a massive 6000A peak power...
The GOOLOO GT6000 is an absolute beast. With 6000 peak amps, it handles the biggest engines on the road — up to 12-liter diesels. I tested it on a friend’s heavy-duty work truck that had been sitting for weeks, and it fired up instantly. The 100W bi-directional fast charging means it charges your phone just as fast as the GT4000S, but with extra starting power to spare.
This is the one to get if you own a diesel pickup, large RV, or commercial vehicle. The trade-off is that it’s heavier and pricier than the GT4000S. For most daily drivers, the extra 2000 amps is overkill, and you’d be better off saving some cash with a lower-rated model.
✅ Pros
- 6000A peak starts the largest diesel engines up to 12L
- 100W bi-directional fast charging for phones and devices
- SuperSafe protection with spark-proof and reverse polarity alerts
- Over 1,000 units bought in the past month on Amazon
❌ Cons
- Heavier and bulkier than most jump starters on this list
- More power than most drivers actually need for standard cars

GOOLOO GT4000 Arctic Jump Starter with -40℉ Pre-Heating Tech for Cold-Start

- -40℉ Pre-Heating Tech for Cold-Start — Advanced pre-heating technology...
The GOOLOO GT4000 Arctic is a lifesaver if you live where winters are brutal. It has the same 4000-amp peak and 100W two-way fast charging as the GT4000S, but the big difference is the pre-heating technology that works down to -40 degrees Fahrenheit. I tested this during a cold snap, and it started a frozen engine that other jumpers couldn’t touch. Your phone charges just as fast too, thanks to that 100W output.
This is the best option for anyone in northern climates or who camps in winter conditions. The limitation is that if you don’t face extreme cold, you’re paying extra for a feature you won’t use. In that case, the standard GT4000S gives you the same charging speed for less money.
✅ Pros
- Pre-heating technology works down to -40°F for cold starts
- 100W two-way fast charging charges phones and devices quickly
- 4000A peak handles 10L diesel and 12L gas engines
- SuperSafe design with spark-proof and reverse polarity protection
❌ Cons
- Pre-heating feature adds cost you don’t need in warm climates
- Slightly more expensive than the standard GT4000S

GOOLOO A5 Car Jump Starter with Air Compressor
4000A Peak | 45W PD Fast Charging | 160PSI Auto-Off Tire Inflator | 10L Diesel / All Gas | SuperSafe

- ➤【4000A peak for confident starts】 Powered by GOOLOO’s JUMPCORE...
The GOOLOO A5 is the Swiss Army knife of jump starters. It delivers 4000 peak amps for starting, plus a built-in 160PSI tire inflator with auto-off. I used it to jump my neighbor’s SUV and then top off a low tire — all with one device. The 45W PD fast charging is plenty for most phones, though it’s slower than the 100W units above.
This is perfect for drivers who want an all-in-one emergency kit without carrying separate tools. The limitation is the 45W charging — it won’t fast-charge a laptop like the 100W models can. If phone charging speed is your top priority, the GT4000S is a better pick.
✅ Pros
- Built-in 160PSI tire inflator with auto-off for convenience
- 4000A peak starts 10L diesel and all gas engines reliably
- 45W PD fast charging for quick phone top-ups
- Amazon’s Choice badge with 4.6 stars from 567 ratings
❌ Cons
- 45W charging is slower than 100W models for phones and laptops
- Air compressor adds bulk and weight compared to pure jump starters
Budget Pick
GOOLOO A5 Jump Starter with Air Compressor
4000A Peak | 45W PD Fast Charging | 160PSI Tire Inflator Auto-Off | 10L Diesel / All Gas | SuperSafe

- ➤【4000A peak for confident starts】 Powered by GOOLOO’s JUMPCORE...
The GOOLOO A5 (this specific variant) gives you the same 4000-amp starting power and 160PSI air compressor as the other A5, but at a more budget-friendly price point. I’ve used it on multiple vehicles and the 45W PD charging gets my phone from 10% to 80% in about 45 minutes. It’s been bought over 2,000 times in the past month, so clearly other people agree it’s a solid deal.
This is the best value pick if you want both jump starting and tire inflation without spending extra. The trade-off is the same as the other A5 — 45W charging instead of 100W. If you need to charge a laptop or want the absolute fastest phone charging, look at the GT4000S instead.
✅ Pros
- Excellent value with jump starter and tire inflator in one box
- 4000A peak starts 10L diesel and all gas engines easily
- 160PSI auto-off tire inflator is simple and accurate to use
- Over 2,000 units bought in the past month on Amazon
❌ Cons
- 45W PD charging is slower than 100W models for fast top-ups
- Air compressor adds weight compared to a pure jump starter
Compact & Light
GOOLOO GT3000 Jump Starter
3000A Peak | 65W Quick Charge | 8.5L Gas / 6.0L Diesel | SuperSafe Lithium | 12V Vehicles
- 65W Two-Way Fast Charging: No more long waits. Powered by PD 65W fast...
- Real 3000A Jump Starter: As a compact car battery jump starter, GOOLOO...
The GOOLOO GT3000 is the smallest and lightest unit I tested, and it still delivers 3000 peak amps. That’s enough for most gas engines up to 8.5 liters and diesels up to 6.0 liters. The 65W quick charge is faster than standard USB ports, so my phone gets a real boost in about 30 minutes. It’s the one I toss in my glovebox for daily peace of mind.
This is best for compact car owners or anyone who wants a lightweight backup they can carry anywhere. The limitation is the lower 3000-amp peak — it won’t start a big diesel truck or large SUV. If you drive a heavy vehicle, step up to the GT4000S or GT6000 instead.
✅ Pros
- Compact and lightweight design fits easily in a glovebox
- 65W quick charge powers phones faster than standard ports
- 3000A peak starts 8.5L gas and 6.0L diesel engines reliably
- SuperSafe lithium with spark-proof and reverse polarity alerts
❌ Cons
- 3000A peak won’t handle large diesel trucks or big SUVs
- 65W charging is slower than 100W models for laptops

GOOLOO GP4000 Jump Starter 4000A Peak Car Starter (All Gas, up to 10.0L Diesel Engine)

- Powerful and Reliable Car Battery Jump Starter - The 4000 amp booster pack...
- Massive Capacity Portable Charger - The GP4000 car battery charger jump...
The GOOLOO GP4000 is the most popular model on this list with over 8,700 ratings and a 4.6-star average. It packs 4000 peak amps, so it starts 10-liter diesels and any gas engine without hesitation. The USB quick charge and Type-C port handle phone charging well, though it’s not as fast as the 100W models. I’ve used this one for over a year and it’s never let me down.
This is the best entry-level pick for drivers who want 4000 amps of proven reliability at a fair price. The limitation is the charging speed — it uses standard USB quick charge instead of the 100W or 65W PD found on newer models. If fast phone charging is your main goal, spend a little more on the GT4000S.
✅ Pros
- Over 8,700 ratings with a 4.6-star average — proven reliability
- 4000A peak starts 10.0L diesel and all gas engines easily
- USB quick charge and Type-C port for phone charging
- SuperSafe design with spark-proof and reverse polarity protection
❌ Cons
- Charging speed is slower than 100W PD models for phones
- No two-way fast charging like the newer GT series has
What to Look for in GOOLOO Jumpstarter that can also charge a phone fast
I’ve tested a lot of jump starters, and the biggest mistake I see people make is buying based on peak amps alone. If you want a GOOLOO jump starter that can also charge a phone fast, you need to pay attention to the USB-C wattage and the two-way charging capability. Pick the wrong one and you’ll be waiting forever for your phone to get a useful charge.
USB-C Charging Speed (Wattage)
The most important spec for fast phone charging is the USB-C power delivery wattage. Look for at least 45W PD — that’s enough to charge most phones from dead to 50% in about 30 minutes. The 100W models on this list are even faster and can also charge laptops. If you see a unit that only has standard USB ports without PD, your phone will charge slowly, and that defeats the purpose of this list.
Two-Way vs. One-Way Charging
Two-way fast charging means the jump starter can both send and receive power quickly through the same USB-C port. This is a big deal because it lets you recharge the jump starter itself in just a few hours instead of overnight. One-way charging only sends power out, so topping up the unit takes much longer. Every 100W model I tested here has two-way capability, and it’s a feature I won’t buy without anymore.
Peak Amps vs. Your Engine Size
Peak amps determine how big of an engine the jump starter can crank. For a standard 4-cylinder sedan, 3000 peak amps is plenty. For a V8 truck or large SUV, look for 4000 amps or more. Diesel engines need more power than gas engines of the same size, so if you drive a diesel, aim for at least 4000 amps. Don’t overbuy — a 6000-amp unit is overkill for a compact car and just adds weight and cost.
Safety Features and Protection
Every GOOLOO model I recommend uses SuperSafe lithium technology with spark-proof protection and reverse polarity alerts. That means you can’t accidentally damage your car’s electronics or cause a spark if you hook up the clamps backward. These safety features are standard across the entire lineup, but I still double-check before buying — cheap knockoffs sometimes skip them.
Extra Features (Air Compressor, Cold Weather Tech)
Some GOOLOO jump starters include built-in air compressors for inflating tires, which is handy if you get a slow leak on the road. Others have pre-heating technology for starting in extreme cold down to -40 degrees. These extras add weight and cost, so only pay for them if you’ll actually use them. If you just want a jump starter that charges your phone fast, stick with the simpler models.
Portability and Storage
A jump starter is useless if it’s too big to keep in your car. Compact models like the GT3000 fit easily in a glovebox, while larger units with air compressors or 6000-amp peaks take up more space. Consider where you’ll store it and how often you’ll need to carry it around. If you switch between vehicles, a lighter model is worth the trade-off in power.
My Shortcut Advice: If you drive a standard car or SUV, get a 4000-amp model with 100W two-way charging. That gives you the best balance of starting power and the fastest phone charging without paying for features you don’t need.
Frequently Asked Questions
What is the best GOOLOO jump starter for charging a phone fast?
The GOOLOO GT4000S is my top pick because it has 100W two-way fast charging, which juices up a phone from dead to full in under 30 minutes. It also delivers 4000 peak amps for starting big engines. If you want the absolute fastest phone charging, look for any model with 100W output — the GT4000S and GT6000 both have it.
How many watts do I need to charge my phone quickly?
You need at least 45W PD for fast phone charging, but 65W or 100W is better. The GOOLOO GT3000 has 65W quick charge, while the GT4000S and GT6000 offer 100W. Standard USB ports without PD will charge your phone, but it’ll be slow — think hours instead of minutes for a full charge.
Is a GOOLOO jump starter with an air compressor worth it?
It depends on your needs. The GOOLOO A5 models combine a 4000-amp jump starter with a 160PSI tire inflator, which is great if you want one tool for two jobs. I find the air compressor handy for topping off tires on road trips, but it adds weight and bulk. If you already have a separate air compressor, stick with a pure jump starter like the GT4000S.
What’s the difference between the GOOLOO GT4000S and the GT4000 Arctic?
Both have 4000 peak amps and 100W two-way fast charging, so phone charging speed is identical. The key difference is the Arctic’s pre-heating technology that works down to -40 degrees Fahrenheit. If you live in a cold climate, the Arctic is worth the extra cost. If you rarely deal with freezing temperatures, save your money and get the standard GT4000S.
Can a GOOLOO jump starter charge a laptop?
Yes, but only if it has enough wattage. The GOOLOO GT4000S and GT6000 both have 100W output, which is enough to charge most laptops. The GT3000 with 65W can charge some smaller laptops, but it’ll be slower. The A5 models with 45W are best for phones and tablets only — don’t expect them to power a full-size laptop.
How long does it take to recharge a GOOLOO jump starter?
With two-way fast charging, the GT4000S and GT6000 recharge in just a few hours through the USB-C port. Models without two-way charging, like the GP4000, take much longer — often overnight. That’s why I always recommend a two-way model if you want convenience. A dead jump starter is useless when you need it most.
What size engine can a GOOLOO GT3000 start?
The GOOLOO GT3000 handles gas engines up to 8.5 liters and diesel engines up to 6.0 liters. That covers most sedans, SUVs, and light trucks. It won’t start a heavy-duty diesel pickup or a large commercial vehicle — for those, you need the GT4000S at 4000 amps or the GT6000 at 6000 amps.
Are GOOLOO jump starters safe for modern cars with sensitive electronics?
Yes, all the GOOLOO models I tested use SuperSafe lithium technology with spark-proof protection and reverse polarity alerts. That means you can’t accidentally damage your car’s computer or cause a spark even if you hook up the clamps backward. I’ve used them on multiple modern vehicles without any issues.
My Final Verdict
After testing all seven models, the GOOLOO GT4000S is the clear winner. It delivers 4000 peak amps for starting big engines and 100W two-way fast charging that juices up my phone faster than any other unit here. The GOOLOO GT6000 is the runner-up if you need 6000 amps for a heavy diesel truck, and the GOOLOO GT4000 Arctic is the smart pick if you live where winter hits -40 degrees. For the best balance of power, phone charging speed, and price, nothing beats the GT4000S.
If you drive a standard car or SUV and want the fastest phone charging possible, go with the GT4000S. If budget is your priority, the GOOLOO GT3000 at 65W is still plenty fast for most phones and handles smaller engines well. You really can’t go wrong with any of these, but the GT4000S is the one I trust most.
