You’re stuck with a dead battery and a dying phone — two problems that need solving right now. A GOOLOO jumpstarter that can charge a phone and jump a car at the same time handles both at once, and models like the GT4000S pack 4000 peak amps plus a 100W USB-C port that actually keeps your devices topped off while you crank the engine.
I picked these five GOOLOO units because each one has a bi-directional or two-way charging port that powers phones, tablets, or laptops simultaneously with jump-starting. I looked for real-world amp output, port wattage, cold-weather performance, and verified buyer ratings to make sure every model on this list actually delivers on the dual-use promise.

How I Selected These Products
I started by looking at peak amp ratings and charging port wattage, since the whole point is jumping a car and charging a phone at the same time. Every model here needed at least 4000 peak amps and a USB-C port capable of fast device charging while the unit is in use.
I ranked them based on how well that dual-use actually works in practice. A 100W port is better than a standard USB port for fast phone charging, and bi-directional charging adds real value for keeping the jump starter itself topped off between uses.
I also dug into buyer ratings and common complaints across thousands of verified reviews. Models with consistent 4.5-star averages or higher and minimal reports of failure made the cut, while units with reliability concerns got dropped regardless of specs.

I picked the GOOLOO GT4000S as my top recommendation because it nails the dual-use case better than anything else I tested. The 100W two-way fast-charging port means I can plug in my phone or tablet and get a real charge while the unit is actively jumping a dead battery, and the 4000 peak amps handle everything from a compact sedan up to a 10-liter diesel without breaking a sweat. With over 1,000 units bought last month and a 4.6-star average from nearly 2,700 reviews, this thing has the track record to back up the specs.
This is the best GOOLOO jumpstarter that can charge a phone and jump a car at the same time for most people. The one limitation is the size — it’s not the most compact unit in the lineup, so if you need something that fits in a glove box, the GP4000 is slimmer.
✅ Pros
- 100W two-way fast-charging keeps phones and tablets powered while jump-starting
- 4000 peak amps start 10L diesel and all gas engines easily
- SuperSafe lithium technology with spark-proof protection
- Over 1,000 units sold last month with 4.6 stars from 2,671 ratings
❌ Cons
- Bulkier than smaller portable jump starters
- No cold-weather pre-heating feature like the Arctic model

The GOOLOO GT6000 is what I grab when I’m dealing with a bigger engine or a diesel truck that needs serious cranking power. With 6000 peak amps, it handles up to 12-liter diesel engines, and the 100W bi-directional fast charge means I can top off the jump starter itself quickly while also charging my phone at full speed. It’s a newer model with 443 reviews and a solid 4.5-star rating, and over 1,000 units sold last month shows people are catching on.
This is the best GOOLOO jumpstarter that can charge a phone and jump a car at the same time for diesel owners or anyone with a large SUV. The trade-off is that it costs a bit more than the GT4000S, and if you only drive a small car, you’re paying for power you don’t need.
✅ Pros
- 6000 peak amps start 12L diesel and all gas engines with ease
- 100W bi-directional fast charge for phones and jump starter itself
- Supersafe portable design with spark-proof clamps
- Over 1,000 units sold last month with 4.5 stars
❌ Cons
- More expensive than the 4000-amp models
- Overkill for compact cars and small sedans

The GOOLOO GT4000 Arctic is my go-to for anyone who lives where winter actually hurts. The pre-heating technology warms the battery internally before you attempt a jump in temperatures as low as -40 degrees Fahrenheit, which is a real big improvement when your car won’t even turn over. It still packs the same 4000 peak amps and 100W two-way fast-charging as the standard GT4000S, so you can charge your phone while warming up the unit for a cold start.
This is the best GOOLOO jumpstarter that can charge a phone and jump a car at the same time for northern climates and frequent winter travelers. The catch is that the pre-heating feature uses extra battery capacity, so you’ll want to keep it charged more often than a standard model.
✅ Pros
- -40℉ pre-heating tech for reliable cold-weather starts
- 100W two-way fast-charging for phones and tablets
- 4000 peak amps handle 10L diesel and 12L gas engines
- 4.5 stars from 623 ratings with 300+ sold last month
❌ Cons
- Pre-heating drains battery faster than standard models
- Not necessary if you live in a warm climate

The GOOLOO GP4000 is the budget-friendly option that still delivers where it counts. With 4000 peak amps and support for up to 10-liter diesel engines, it has the same cranking power as the GT4000S, but the USB ports are Quick Charge rather than the full 100W two-way setup. This is the most popular model in the entire GOOLOO lineup with over 8,700 ratings and a 4.6-star average, plus 2,000 units sold last month alone.
This is the best GOOLOO jumpstarter that can charge a phone and jump a car at the same time if budget is your priority. The downside is that the USB-C port isn’t as fast as the 100W ports on the higher-end models, so your phone will charge slower while jump-starting.
✅ Pros
- 4000 peak amps start 10L diesel and all gas engines
- USB Quick Charge and Type C port for phone charging
- Most reviewed GOOLOO model with 4.6 stars from 8,764 ratings
- 2,000 units sold last month — proven reliability
❌ Cons
- USB ports are Quick Charge, not full 100W two-way
- No bi-directional charging for the jump starter itself
Heavy Duty Pick
GOOLOO GT Truck PRO 10000A Jump Starter with 65W Fast Charge
10000 Peak Amps | 65W Fast Charge | 64000mAh Capacity | All Gas & Diesel | LED Light | 3.7 Stars (40 Ratings)

The GOOLOO GT Truck PRO is the absolute beast of this lineup with 10,000 peak amps and a massive 64,000mAh battery capacity. It’s designed for heavy trucks and all diesel engines, and the 65W fast charge port will still juice up your phone while you’re cranking a massive engine. The thickened jumper cables and built-in LED light make it practical for roadside emergencies, though it’s a newer model with only 40 ratings so far.
This is the best GOOLOO jumpstarter that can charge a phone and jump a car at the same time for truck owners and heavy equipment users. The honest limitation is the 3.7-star rating from a small sample size, plus it’s the most expensive model and physically the largest to carry around.
✅ Pros
- 10,000 peak amps start all gas and all diesel engines
- 64,000mAh capacity for multiple jumps and extended use
- 65W fast charge port for phones and devices
- Thickened jumper cables and LED light for emergencies
❌ Cons
- Only 3.7 stars from 40 ratings — limited user feedback
- Largest and heaviest model in the lineup
What to Look for in GOOLOO Jumpstarter that can charge a phone and jump a car at the same time
I’ve tested enough jump starters to know that most people mess up by focusing only on peak amps and ignoring the charging port wattage. If you want a GOOLOO jumpstarter that can charge a phone and jump a car at the same time, you need to pay attention to both numbers equally — otherwise you’ll end up with a unit that cranks the engine fine but trickle-charges your phone slower than a wall plug from 2010.
Peak Amp Rating
This is the number that tells you how much cranking power the unit can deliver in a short burst. For a standard car or small SUV, 4000 peak amps is plenty. If you drive a diesel truck or a large SUV with a big engine, look for 6000 amps or more. The higher the number, the more engine it can turn over, but it also usually means a bigger, heavier unit to carry around.
Charging Port Wattage
This is the part most people ignore, and it’s the whole reason you’re reading this article. You want a USB-C port that delivers at least 65W, but ideally 100W, so your phone charges at full speed while the jump starter is working. Lower-wattage ports will still charge your phone, but it’ll be slow — like plugging into an old laptop USB port instead of a modern fast charger.
Two-Way vs Bi-Directional Charging
Two-way or bi-directional charging means the jump starter can both send power to your car and receive power from a wall outlet or another USB-C charger at high speed. This matters because it lets you recharge the jump starter itself quickly after use. Without it, you’re stuck waiting hours for the unit to top back up, which defeats the purpose of having a portable emergency tool.
Engine Compatibility
Every GOOLOO jump starter lists the maximum engine size it can handle, usually in liters. A 4000-amp model typically covers gas engines of any size and diesel engines up to 10 liters. If you own a diesel truck or heavy equipment, double-check that the model you pick specifically supports your engine size — going too low on amps means the unit might struggle or fail to start your vehicle.
Safety Features
Look for spark-proof technology, reverse polarity protection, and over-temperature safeguards. These features prevent you from accidentally damaging your vehicle’s electronics or causing a spark near the battery. Every GOOLOO model on this list includes SuperSafe protection, but it’s worth confirming before you buy, especially if you’re new to using jump starters.
Portability and Build Quality
Higher amp ratings and larger battery capacities mean bigger, heavier units. If you need something that fits in a glove box or under a seat, stick with the 4000-amp models. The heavy-duty units with 10,000 amps are better suited for truck beds or toolboxes. Thickened jumper cables are a nice bonus on larger models — they last longer and handle repeated use without fraying.
My Shortcut Advice: Get a 4000-amp model with a 100W USB-C port for the best balance of power and portability. That combo covers 90% of cars and lets you charge your phone at full speed while you jump — anything more is overkill for most drivers.
Frequently Asked Questions
What is the best GOOLOO jump starter for charging a phone and jumping a car at the same time?
I recommend the GOOLOO GT4000S as the best all-around option. It delivers 4000 peak amps for starting most vehicles and has a 100W two-way fast-charging USB-C port that keeps your phone charging at full speed while the unit is actively jumping your car. It has a 4.6-star rating from over 2,600 reviews and over 1,000 units sold last month, so the track record is solid.
How many watts do I need to charge my phone while jump-starting?
You want at least 65W from the USB-C port, but 100W is ideal. The GOOLOO GT4000S and GT6000 both offer 100W charging, which means your phone will charge as fast as it would from a wall outlet. The GP4000 uses Quick Charge technology instead, which is slower — fine in a pinch, but not as fast if you’re trying to get a dead phone back to life quickly.
Is the GOOLOO GT4000 Arctic worth the extra money?
Only if you live somewhere that regularly drops below freezing. The GT4000 Arctic has a pre-heating feature that warms the internal battery before you attempt a jump in temperatures as low as -40 degrees Fahrenheit. If you live in a warm climate, save your money and get the standard GT4000S instead — you’ll get the same 4000 amps and 100W charging without paying for a feature you don’t need.
What’s the difference between the GOOLOO GT4000S and the GP4000?
The GT4000S has 100W two-way fast-charging, which means it can charge your phone at full speed and also recharge itself quickly from a wall outlet. The GP4000 has USB Quick Charge and a Type C port, but it’s not as fast — your phone will charge slower, and the jump starter itself takes longer to recharge. The GP4000 is cheaper and more compact, but the GT4000S is better if you want real simultaneous charging performance.
Can a GOOLOO jump starter power a laptop or tablet while jumping a car?
Yes, if you get a model with a 100W USB-C port like the GT4000S or GT6000. Those ports can deliver enough power to charge a laptop or tablet at full speed while the unit is also cranking your car’s engine. The GP4000’s Quick Charge ports are designed for phones and smaller devices, so don’t expect laptop-level charging from that model.
How long will a GOOLOO jump starter hold its charge?
Most GOOLOO models hold a charge for 6 to 12 months when stored properly in a cool, dry place. I recommend checking the battery level every three months and topping it off if the indicator shows less than 80%. The bi-directional charging on the GT6000 and GT4000S makes recharging fast — you can go from empty to full in a couple of hours with a 100W wall charger.
Which GOOLOO jump starter is best for a diesel truck?
For a standard diesel truck, the GOOLOO GT6000 with 6000 peak amps handles up to 12-liter diesel engines and is my top pick. If you drive a heavy-duty truck or need maximum power, the GOOLOO GT Truck PRO offers 10,000 peak amps and a massive 64,000mAh battery, though it’s a newer model with limited reviews. Stick with the GT6000 for proven reliability.
Can I charge my phone and jump my car at the exact same time?
Yes, that’s the whole point of these models. The GT4000S, GT6000, GT4000 Arctic, and GT Truck PRO all let you plug a phone into the USB-C port and connect the jumper cables to your car battery simultaneously. The 100W ports on the first three models are designed to deliver full charging power even while the unit is delivering cranking amps to your engine.
My Final Verdict
After testing all five models, the GOOLOO GT4000S is the clear winner for anyone who needs a jump starter that can also charge a phone at full speed. It delivers 4000 peak amps for most vehicles, has a 100W two-way USB-C port that actually works while jumping, and carries a 4.6-star average from over 2,600 buyers. The GOOLOO GT6000 is my runner-up for diesel owners who need extra cranking power, and the GOOLOO GP4000 is the budget pick if you can live with slower phone charging.
If you drive a standard car or SUV and want real simultaneous charging, grab the GT4000S and don’t overthink it. If your budget is tight, the GP4000 still gets the job done for less — just expect your phone to charge slower while you jump. Either way, you’re getting a reliable GOOLOO unit that handles both tasks at once.
