Nothing worse than turning the key and getting nothing but silence. That’s the exact moment you need a jump starter that can handle a totally dead battery, not just a weak one. I’ve spent weeks testing GOOLOO’s lineup to find which models actually deliver when your battery is at zero.
I picked these 9 based on three things: peak amperage ratings for big engines, real-world performance on deeply discharged batteries, and safety features like spark-proof tech. Every model here can start a car that’s been sitting for months, but some do it way better than others.

How I Selected These Products
I looked at peak amperage ratings first because a completely dead battery needs serious cranking power. Every model here had to handle at least 3000A to qualify for this list. I also checked for safety features like spark-proof tech and reverse polarity protection.
Value mattered too. I compared what you get for the money — extra features like air compressors or fast charging ports. A jump starter that sits in your trunk and never gets used is worthless, so usability and portability were big factors in my rankings.
Finally, I dug through thousands of user reviews across multiple models. Real-world reliability over months and years tells you more than specs on a box. I prioritized units with consistent 4.5+ ratings and high purchase volumes from verified buyers.

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 GT4000S is the GOOLOO I reach for first when a battery is truly stone dead. Its 4000A cranking power fires up a 10L diesel like it’s a lawnmower, and the 100W two-way fast-charging means I can top off the jump box itself in under an hour. I tested this on a truck that sat for six months and it turned over on the first try without any hesitation.
This is the one I recommend for anyone with a big gas truck, a diesel rig, or a fleet vehicle that needs reliable starting power. The only downside is the size — it’s a bit chunky for a glovebox, so it lives better in a trunk or under a seat.
✅ Pros
- 4000A peak handles completely dead batteries with ease
- 100W two-way fast-charging recharges the unit quickly
- Works on all gas engines and up to 10L diesel
- SuperSafe design prevents sparking and reverse polarity
- Over 1,000 bought in the past month — proven popularity
❌ Cons
- Bulky design won’t fit in most gloveboxes
- No built-in air compressor for tire emergencies

GOOLOO A5 Car Jump Starter with Air Compressor
4000A Peak | 160PSI Air Compressor | 10L Diesel / All Gas | 45W PD Fast Charging | Auto-Off Inflator
- 【6-in-1, compact & road-ready】 The 2026 GOOLOO A5 jump starter is a...
- ➤【4000A peak for confident starts】 Powered by GOOLOO’s JUMPCORE...
The A5 combines a 4000A jump starter with a 160PSI tire inflator that shuts off automatically, and I love having both tools in one box. The 45W PD fast charging means my phone charges at full speed while the unit sits in my trunk. I used the inflator to top off a flat tire after a jump start and the auto-off feature saved me from over-inflating.
This is perfect if you want one device that handles dead batteries and low tires without carrying two separate units. The trade-off is that the air compressor is slower than a standalone unit, so it’s best for topping off rather than filling a completely flat tire from zero.
✅ Pros
- 4000A peak with built-in 160PSI air compressor
- 45W PD fast charging for phones and tablets
- Auto-off inflator prevents over-inflation damage
- Amazon’s Choice badge with strong reviews
- Works on all gas and up to 10L diesel engines
❌ Cons
- Air compressor is slow for filling completely flat tires
- Heavier than a dedicated jump starter alone

This A5 variant gives you the same 4000A jump starting power and 160PSI inflator as the other A5, but at a more accessible price point. Over 2,000 people bought this in the past month, and after testing it on a dead sedan battery, I get why — it fired up instantly and the 45W PD port charged my phone in under 30 minutes.
This is the best pick for budget-conscious buyers who still want both jump starting and tire inflation in one kit. The catch is the same as the other A5: the inflator works fine for topping off but struggles with a fully flat tire, so keep a separate pump if that’s a regular issue.
✅ Pros
- 4000A peak for dead batteries on gas and 10L diesel
- 160PSI auto-off tire inflator included
- 45W PD fast charging for modern devices
- Over 2,000 bought last month — very popular
- Strong value for a jump starter and inflator combo
❌ Cons
- Inflator is slow on completely flat tires
- Bulky design compared to pure jump starters

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 GT4000 Arctic is the only GOOLOO I’ve tested with pre-heating technology that warms the internal battery before you attempt a jump in freezing conditions. It still delivers 4000A peak power for up to 10L diesel and 12L gas engines, and the 100W two-way fast-charging keeps it ready to go. I left this in my truck overnight at 15°F and it started a dead battery without any lag.
This is the one to get if you live where winter temps regularly drop below freezing and you need guaranteed starts. The downside is that the pre-heating feature uses extra battery power, so you’ll want to recharge it more often than a standard unit if you’re not using it regularly.
✅ Pros
- Pre-heating tech works down to -40°F for cold starts
- 4000A peak handles 12L gas and 10L diesel engines
- 100W two-way fast-charging for quick top-ups
- SuperSafe spark-proof and reverse polarity protection
- 300+ bought last month in cold regions
❌ Cons
- Pre-heating drains battery faster between uses
- More expensive than standard 4000A models

- Massive Capacity Portable Charger - The GP4000 car battery charger jump...
The GP4000 is the most popular GOOLOO on Amazon with over 8,700 ratings and 2,000 bought last month, and for good reason. It delivers a full 4000A peak for dead batteries on all gas engines and up to 10L diesel, plus USB quick charge and a Type-C port for your devices. I tested this on a completely dead V8 and it cranked like the battery was brand new.
This is the go-to for drivers who want maximum cranking power at a budget-friendly price without extra features they won’t use. The limitation is that it lacks the 100W fast-charging of the GT4000S, so recharging the unit itself takes longer between jumps.
✅ Pros
- 4000A peak for dead batteries on big engines
- Over 8,700 ratings — most reviewed GOOLOO model
- USB quick charge and Type-C port included
- SuperSafe lithium with spark-proof protection
- 2,000+ bought last month — proven demand
❌ Cons
- Slower recharge time without 100W fast-charging
- No air compressor or extra utility features

- Powerful & Compact Jump Starter: It delivers a massive 6000A peak power...
The GT6000 is the most powerful GOOLOO I tested, cranking out 6000A peak for engines up to 12L diesel. The 100W bi-directional fast charge means it recharges itself in a flash and can also power up your laptop or tablet at full speed. I hooked this up to a dead diesel work truck and it spun the starter like the battery was fully charged.
This is the one for heavy-duty truck owners, fleet managers, or anyone with a massive diesel engine that needs serious cranking power. The trade-off is that it’s the largest and heaviest unit here, so it’s not ideal for tossing in a small car’s glovebox.
✅ Pros
- 6000A peak handles the biggest diesel engines up to 12L
- 100W bi-directional fast charge for rapid recharging
- Works on all gas engines without any issues
- SuperSafe spark-proof and reverse polarity protection
- Over 1,000 bought last month for heavy-duty use
❌ Cons
- Largest and heaviest unit in the GOOLOO lineup
- Overkill for small cars and sedans

The A3 is a beast in a smaller package, delivering 3000A peak for engines up to 9L gas and 6.5L diesel while also packing a 150PSI auto-shutoff tire inflator. Over 10,000 people bought this in the past month, and after testing it on a dead minivan, I see why — it’s compact enough to stash anywhere but still powerful enough for most vehicles. The 150PSI inflator with auto-shutoff saved me from guessing tire pressure.
This is the best choice for everyday drivers who want a jump starter and inflator that fits under a seat without breaking the bank. The limitation is the 3000A peak won’t handle the biggest diesel trucks, so stick with the GT6000 if you drive a heavy-duty rig.
✅ Pros
- 3000A peak with 150PSI auto-shutoff tire inflator
- Over 10,000 bought last month — most popular combo
- Compact size fits under most car seats
- Amazon’s Choice with 4.5 stars from 4,108 ratings
- SuperSafe spark-proof and reverse polarity protection
❌ Cons
- 3000A peak not enough for large diesel trucks
- Inflator slower than standalone air compressors

It delivers 3000A peak for engines up to 9L gas and 7L diesel, plus USB quick charge and a Type-C port for your devices. I tested this on a dead SUV with a 6L engine and it started without any hesitation, even after sitting for weeks.
This is the perfect pick for budget-minded buyers who want a reliable, well-reviewed jump starter for standard cars, SUVs, and smaller diesel engines. The downside is it lacks the 100W fast-charging of pricier models, so recharging the unit itself takes a bit longer.
✅ Pros
- 3000A peak for up to 9L gas and 7L diesel engines
- 4.7 out of 5 stars — highest rated GOOLOO model
- USB quick charge and Type-C port for devices

The G7 stands out because the jumper cables are built directly into the unit — no more digging around for loose clamps in your trunk. It delivers 3000A peak for engines up to 8.5L gas and 6L diesel, plus 45W fast charging for your phone or tablet. I appreciated not having to untangle cables when testing this on a dead sedan in a dark parking lot.
This is ideal for anyone who hates fumbling with separate cables or wants a clean, all-in-one design for quick access. The catch is that the built-in cables are shorter than standard removable ones, so you need to position the unit closer to your battery terminals.
✅ Pros
- Built-in cables mean no loose parts to lose
- 3000A peak for up to 8.5L gas and 6L diesel
- 45W fast charging for phones and tablets
- SuperSafe spark-proof and reverse polarity protection
- Compact design for easy storage
❌ Cons
- Built-in cables are shorter than removable ones

What to Look for in GOOLOO Jumpstarter for starting a car with a completely dead battery
Buying a GOOLOO jump starter for a completely dead battery isn’t just about picking the one with the highest number on the box. I’ve seen people grab a model that looks powerful but can’t actually deliver enough cranking amps to revive a battery at zero volts. The biggest mistake is ignoring peak amperage and assuming all 4000A units perform the same way.
Peak Amperage (A)
Peak amperage is the single most important spec when your battery is completely dead. A battery with zero charge needs a massive surge of current to spin the starter motor, and if your jump starter doesn’t have enough amps, you’ll get nothing but a click. For most cars and SUVs, 3000A is the minimum I’d recommend. For large diesel trucks or heavy-duty vehicles, look at 4000A or even 6000A to guarantee a start on the first try.
Engine Compatibility (Gas vs. Diesel)
Diesel engines need more cranking power than gas engines because of higher compression ratios. Every GOOLOO model lists the maximum engine size it can handle, like “10L Diesel” or “7L Diesel.” I always tell buyers to check their engine displacement before buying — a 4000A unit rated for 10L diesel will easily start a 6L gas truck, but a 3000A unit might struggle with a big diesel. Always go one step higher than you think you need.
Fast Charging (Recharge Speed)
A jump starter that takes hours to recharge isn’t useful in an emergency. Look for models with 100W two-way or bi-directional fast charging, which can refill the internal battery in under an hour. Lower-end models with standard USB charging can take 4-6 hours to fully recharge, which is a pain if you need to use it again the same day. I prioritize fast charging for anyone who uses their jump starter frequently.
Safety Features (Spark-Proof and Reverse Polarity)
When you’re hooking up to a dead battery in the dark or rain, safety features matter. GOOLOO’s SuperSafe technology prevents sparking and protects against reverse polarity if you accidentally connect the clamps backward. I’ve seen people smoke their electronics by hooking up cables wrong, so I won’t recommend a jump starter without these protections. Every model on this list includes them, but double-check before buying any other brand.
Extra Features (Air Compressor, USB Ports)
Some GOOLOO models add a tire inflator or fast-charging USB ports, which can save you from carrying separate tools. A 160PSI auto-off air compressor is great for topping off tires after a jump, but it won’t replace a full-size pump for completely flat tires. I like having a 45W PD port for charging my phone while I wait for a jump, but don’t pay extra for features you’ll never use.
Portability and Storage
The size and weight of your jump starter determine where you can store it. High-power models like the GT6000 with 6000A are bigger and heavier, so they’re best for trunks or truck beds. Smaller units like the A3 or GP3000 fit under a car seat or in a glovebox. I always tell buyers to measure their storage space before buying — a jump starter that’s too big to carry won’t help when you’re stranded.
My Shortcut Advice: Match the peak amperage to your engine size and always go one step higher than you think you need. For most drivers, a 4000A model like the GOOLOO GT4000S is the sweet spot for dead batteries on gas and diesel engines.
Frequently Asked Questions
What is the best GOOLOO jump starter for a completely dead battery?
The GOOLOO GT4000S is my top pick for reviving a completely dead battery. Its 4000A peak cranking power handles engines up to 10L diesel and all gas engines, plus the 100W two-way fast-charging means the unit itself recharges quickly between uses. I’ve tested it on batteries that read zero volts and it still fired the engine on the first try.
How many amps do I need to start a car with a dead battery?
For a completely dead battery on a standard car or SUV, I recommend at least 3000A peak. If you drive a large truck with a diesel engine, go for 4000A or higher — the GOOLOO GT6000 offers 6000A for up to 12L diesel engines. More amps give you a bigger safety margin when the battery is truly at zero.
Is a GOOLOO jump starter with an air compressor worth it?
Yes, if you want one tool that handles both dead batteries and low tires. The GOOLOO A5 gives you 4000A peak power plus a 160PSI auto-off tire inflator, which is perfect for topping off tires after a jump. Just know the inflator is slower than a standalone air compressor, so it’s best for maintenance rather than filling completely flat tires from scratch.
What’s the difference between the GOOLOO GT4000S and the GP4000?
The GT4000S has 100W two-way fast-charging, which recharges the jump starter itself much faster than the GP4000’s standard USB charging. Both deliver 4000A peak for engines up to 10L diesel, but the GT4000S is better for people who use their jump starter frequently and need quick turnaround. The GP4000 is a solid budget-friendly choice if you don’t mind slower recharge times.
Can a GOOLOO jump starter start a diesel truck?
Yes, but you need to match the model to your engine size. The GOOLOO GT4000S and GP4000 both handle up to 10L diesel, while the GT6000 handles up to 12L diesel with its 6000A peak. For smaller diesel engines under 7L, the GP3000 or A3 with 3000A peak will work fine.
How long does it take to recharge a GOOLOO jump starter?
It depends on the model. Units with 100W fast-charging like the GT4000S and GT6000 recharge in under an hour. Models with standard USB charging like the GP4000 and GP3000 can take 4-6 hours for a full charge. I always recommend fast-charging models if you use your jump starter regularly or share it between multiple vehicles.
Will the GOOLOO GT4000 Arctic work in freezing weather?
Yes, and that’s exactly what it’s designed for. The GT4000 Arctic has pre-heating technology that warms the internal battery before you attempt a jump in temperatures as low as -40°F. It still delivers 4000A peak for engines up to 10L diesel and 12L gas, making it the best choice for cold climates. Just keep in mind the pre-heating feature uses extra battery power, so recharge it more often during winter.
Can I use a GOOLOO jump starter to charge my phone or laptop?
Most models include USB ports for charging devices. The GT4000S and GT6000 have 100W output that can fast-charge laptops and tablets, while the A5 and G7 offer 45W PD fast charging for phones. I’ve charged my phone multiple times from a single jump starter charge, but remember that using the USB ports drains the battery you need for jumping.
My Final Verdict
After testing all nine GOOLOO jump starters on completely dead batteries, the GOOLOO GT4000S is my clear winner. Its 4000A peak power, 100W two-way fast-charging, and reliable performance on engines up to 10L diesel make it the most versatile choice for anyone who needs guaranteed starts. The GOOLOO A5 with air compressor is the runner-up if you want a jump starter and tire inflator in one box, and the GOOLOO GP4000 is the budget-friendly pick that still delivers 4000A of cranking power.
If you drive a standard car, SUV, or light truck, the GT4000S will handle any dead battery situation without breaking a sweat. If you need to save money, the GP4000 gives you the same 4000A peak at a lower price point. Either way, don’t settle for less than 3000A peak when you’re dealing with a battery at zero.
