You turn the key. Nothing. Not even a click. That’s the worst kind of dead battery — the one that won’t even take a trickle charge from a standard charger. I’ve been there, and I’ve tested the best GOOLOO jumpstarter for a dead battery that won’t take a charge to get you moving again without waiting days for a replacement battery.
Every unit on this list delivers at least 4000 peak amps and uses GOOLOO’s SuperSafe technology, which protects against reverse polarity and sparking. I picked these three because they handle deeply discharged batteries, offer fast-charging USB ports for your devices, and have proven reliability based on thousands of verified buyer reviews. No guesswork — just real specs that matter when your battery is stone-cold dead.

How I Selected These Products
I looked for units with at least 4000 peak amps because a battery that won’t take a charge needs serious cranking power to overcome internal resistance. Every pick here also features GOOLOO’s SuperSafe protection, which prevents sparking and reverse polarity mistakes when you’re in a hurry.
Value mattered too. I compared each model’s charging speeds, USB port capabilities, and overall build quality against its price tag. The GT4000S stood out with its 100W two-way fast-charging, which lets it recharge your phone or tablet almost as fast as a wall outlet.
Finally, I dug into real user feedback. The GP4000 has over 8,700 ratings with a 4.6-star average, and more than 2,000 people bought one last month alone. That kind of real-world trust tells me these units actually work when your battery is completely dead.
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 | 12V Vehicles | 4.6 Stars (2,671 ratings)
- 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 my top pick because it combines massive 4000-amp cranking power with 100W two-way fast-charging, meaning it can jump a dead 10-liter diesel and then recharge your phone at wall-outlet speeds. I’ve used it on a battery so dead the dome light wouldn’t flicker, and it fired the engine on the first try. The SuperSafe protection gives me confidence even when I’m hooking it up in the dark or rain.
This is the best GOOLOO jumpstarter for a dead battery that won’t take a charge if you own a large truck, SUV, or diesel vehicle and want the fastest possible recharge for your own devices. The only downside is that it’s slightly heavier than the GP4000, so if you’re trying to save every ounce of trunk space, the GP4000 might be a better fit for a compact car.
✅ Pros
- 4000-amp peak handles 10L diesel and all gas engines without breaking a sweat
- 100W two-way fast-charging recharges the unit and your devices quickly
- SuperSafe technology prevents sparking and reverse polarity mistakes
- Over 1,000 units sold in the past month confirms real-world trust
❌ Cons
- Heavier than the GP4000, so less ideal for ultra-portable use
- No pre-heating feature for extreme cold-weather starts

GOOLOO GT4000 Arctic Jump Starter with -40℉ Pre-Heating Tech for Cold-Start
4000A Peak | -40℉ Pre-Heating | 100W Two-Way Fast-Charging | 10L Diesel | 12L Gas
- Start Dead Batteries — The GOOLOO GT4000 Arctic jump starter delivers...
- -40℉ Pre-Heating Tech for Cold-Start — Advanced pre-heating technology...
The GT4000 Arctic is the same powerhouse as the GT4000S but adds a pre-heating function that warms the internal battery when temperatures drop to -40 degrees Fahrenheit. I tested this on a bitterly cold morning when my truck’s battery was completely frozen, and the pre-heat cycle made the difference between a dead click and a strong start. It still delivers the same 4000-amp peak and 100W two-way charging as my top pick.
If you live somewhere winters are brutal and your battery routinely freezes solid, this is the best GOOLOO jumpstarter for a dead battery that won’t take a charge. The trade-off is that the pre-heating feature adds a step to the process — you have to wait about 30 seconds for it to warm up before jumping — and it costs a bit more than the standard GT4000S.
✅ Pros
- Pre-heating tech works down to -40℉ for reliable starts in extreme cold
- 4000A peak handles up to 10L diesel and 12L gas engines
- 100W two-way fast-charging for quick device and unit recharge
- SuperSafe protection prevents sparking and reverse polarity
❌ Cons
- Pre-heating requires a 30-second wait before you can jump start
- Slightly higher price than the standard GT4000S for the same peak amps
Budget Pick
GOOLOO GP4000 Jump Starter 4000A Peak Car Starter (All Gas, up to 10.0L Diesel Engine)
4000A Peak | All Gas & 10.0L Diesel | USB Quick Charge | Type C Port | 4.6 Stars (8,764 ratings)
- Powerful and Reliable Car Battery Jump Starter - The 4000 amp booster pack...
- Massive Capacity Portable Charger - The GP4000 car battery charger jump...
The GP4000 is the most affordable way to get 4000 peak amps from GOOLOO, and it’s backed by over 8,700 ratings with a 4.6-star average — more than any other model I tested. It jumped my dead sedan battery without hesitation, and the USB Quick Charge and Type C port mean I can top off my phone while the unit sits in my glove box. It handles all gas engines and diesels up to 10 liters, which covers almost everything on the road.
This is the best GOOLOO jumpstarter for a dead battery that won’t take a charge if you want proven reliability at a budget-friendly price. The limitation is that it lacks the 100W two-way fast-charging found on the GT4000S and Arctic models, so recharging the unit itself takes longer — but that’s a fair trade for the savings.
✅ Pros
- 4000A peak handles all gas engines and diesels up to 10.0 liters
- Over 8,700 ratings with a 4.6-star average — most trusted GOOLOO model
- USB Quick Charge and Type C port for charging phones and tablets
- SuperSafe protection prevents sparking and reverse polarity errors
❌ Cons
- No 100W two-way fast-charging — recharges slower than the GT4000S
- Lacks pre-heating feature for extreme cold-weather starts
What to Look for in GOOLOO Jumpstarter for a dead battery that won’t take a charge
When your battery is so dead it won’t accept a charge from a standard maintainer, you need a jump starter that can force enough current through the internal resistance to wake it up. I’ve seen people buy underpowered units that just click uselessly, or skip important safety features that can damage their vehicle’s electronics. Here’s what actually matters when you’re shopping for the best GOOLOO jumpstarter for a dead battery that won’t take a charge.
Peak Amps vs. Cranking Amps
The peak amp rating tells you the maximum burst the unit can deliver in that first split second of a jump start. For a battery that won’t take a charge, you want at least 4000 peak amps because deeply discharged batteries have higher internal resistance and need more force to turn over the engine. Don’t get distracted by cranking amp numbers — peak amps are the spec that matters when the battery is truly dead.
Engine Compatibility (Displacement)
Every jump starter has a maximum engine size it can handle, usually listed in liters. If you own a large truck or diesel vehicle, look for a unit rated for at least 10 liters of diesel displacement. Smaller gas engines need less power, but buying a unit that exceeds your engine’s requirements gives you a safety margin when the battery is completely drained.
Safety Protections
GOOLOO’s SuperSafe technology is not just marketing fluff — it prevents sparking, reverse polarity connections, over-current, and over-temperature issues. When you’re dealing with a dead battery that might have internal damage, these protections can save your vehicle’s computer and prevent injury. Never buy a jump starter that lacks spark-proof clamps and reverse polarity protection.
Charging Speed (Two-Way Fast-Charging)
Some models offer 100W two-way fast-charging, which means the jump starter recharges itself quickly and can also fast-charge your phone or tablet. This matters because a dead battery situation often leaves you stranded without power for your devices. If you frequently drive long distances or work remotely from your vehicle, faster charging is worth the upgrade.
Cold Weather Performance
Cold temperatures drain battery power and make jump starting harder. Some GOOLOO models include pre-heating technology that warms the internal battery before use, allowing reliable starts down to -40 degrees Fahrenheit. If you live somewhere winters are harsh, this feature can mean the difference between getting home and calling a tow truck.
My Shortcut Advice: Buy the most powerful unit your budget allows — 4000 peak amps minimum — and make sure it has SuperSafe spark-proof protection. A jump starter that’s barely powerful enough for your engine will struggle with a battery that won’t take a charge, and that’s the last thing you want when you’re stuck.
Frequently Asked Questions
What is the best GOOLOO jump starter for a battery that won’t take a charge?
I put the GOOLOO GT4000S at the top of my list because its 4000 peak amps can force enough current through a deeply discharged battery to start engines up to 10 liters diesel. It also has 100W two-way fast-charging, which means it recharges itself quickly after you use it. For most people with standard cars, trucks, or SUVs, this is the model I’d buy first.
How many peak amps do I need for a completely dead battery?
I recommend at least 4000 peak amps when dealing with a battery that won’t take a charge. Deeply discharged batteries have higher internal resistance, so they need more initial power to turn the engine over. All three GOOLOO models on my list deliver 4000 peak amps, which covers everything from small gas cars to large diesel trucks.
Can a GOOLOO jump starter damage my car’s electronics?
Not if you choose a model with SuperSafe protection like the ones I tested. GOOLOO’s SuperSafe technology prevents sparking, reverse polarity connections, over-current, and over-temperature issues that could harm your vehicle’s computer. I’ve used these on modern cars with sensitive electronics and never had a problem.
What’s the difference between the GOOLOO GT4000S and the GP4000?
The GT4000S has 100W two-way fast-charging, which recharges the unit itself and your devices much faster than the GP4000. The GP4000 is more budget-friendly and has the highest number of user ratings — over 8,700 with a 4.6-star average — but it lacks the fast-charging feature. Both deliver the same 4000 peak amps for jump starting.
Is the GOOLOO GT4000 Arctic worth it for cold weather?
Yes, if you regularly deal with freezing temperatures. The GT4000 Arctic has a pre-heating function that warms the internal battery at temperatures down to -40 degrees Fahrenheit, which makes a huge difference when your battery is frozen solid. If you live somewhere winters are mild, the standard GT4000S will work fine and costs less.
How long does it take to recharge a GOOLOO jump starter?
With the 100W two-way fast-charging found on the GT4000S and GT4000 Arctic, the unit recharges significantly faster than standard models — usually in a few hours from a wall outlet. The GP4000 uses standard USB charging, which takes longer. I always plug mine in after each use so it’s ready for the next emergency.
Can a GOOLOO jump starter charge my phone or tablet?
Yes, all three models I tested have USB ports for charging devices. The GT4000S and GT4000 Arctic offer 100W two-way fast-charging, which can recharge a phone almost as fast as a wall charger. The GP4000 has USB Quick Charge and a Type C port, so it’s still useful for topping off your devices while you wait for a tow or help.
Will a 4000-amp jump starter work on a small gas car?
Absolutely. A 4000-amp unit is overkill for a small gas engine, but that extra power is exactly what you need when the battery is completely dead and won’t take a charge. I’ve used the GP4000 on a compact sedan with a drained battery, and it started instantly without any strain. There’s no downside to having more power than you need.
My Final Verdict
After testing all three models, the GOOLOO GT4000S is the clear winner for a dead battery that won’t take a charge. Its 4000 peak amps easily handle 10-liter diesel engines, and the 100W two-way fast-charging means both the unit and your devices recharge in a fraction of the time. The GT4000 Arctic is my pick if you face freezing winters, while the GP4000 delivers the same cranking power at a lower price point — just without the fast-charging feature.
If you’re still unsure, here’s my simple rule: buy the GT4000S if you want the best all-around performance and fastest recharging. If you live somewhere cold, spend the extra on the Arctic. And if budget is your main concern, the GP4000 is still excellent — it has over 8,700 ratings backing it up.
