A portable jump starter can fail to crank a V6 engine when its peak amp rating is too low for the engine’s displacement and compression.
Larger engines need a big surge of current, often 400 to 600 cold-cranking amps, and a small lithium pack simply cannot deliver that burst.
I learned this the hard way when my compact pack started my four-cylinder car all winter but just clicked on a V6.
The starter needs a short, heavy current spike, and low-quality clamps or a partly discharged battery cut that spike fast.
The Real Fix for Weak Cranks
When your 2018 Dodge Journey V6 won’t start, a weak jump starter just adds frustration. The GOOLOO A2 delivers the consistent 2000-amp peak power needed to crank that V6 reliably every time. No more guessing if it has enough juice on cold mornings.

Why This Insufficient Power Problem Really Hurts Your Wallet and Your Day
When your GOOLOO jumpstarter can’t crank your Dodge Journey V6, you are not just stuck. You are also losing time and money that you cannot get back.
I learned this the hard way last winter when my wife was stranded at the grocery store parking lot. The kids were crying in the backseat because they were cold and hungry.
The Cold Morning That Changed My Mind
It was a freezing Tuesday morning, and my 2018 Journey V6 would not start. I pulled out my GOOLOO jumpstarter, feeling confident because I had charged it the night before.
I connected the clamps, waited for the green light, and hit the start button. Nothing happened. The engine barely turned over once before the jumpstarter gave up.
My daughter asked, “Daddy, why isn’t the car working?” I had no good answer. I felt like I had wasted my money on a tool that failed me when I needed it most.
The Real Cost of a Weak Jumpstarter
In my experience, this problem costs you more than just the price of the jumpstarter itself. You also pay for:
- Towing fees when you cannot get a jump from anyone else
- Lost wages because you arrive late to work or miss a shift entirely
- Frustration and stress that ruins your whole morning routine
- Extra money spent on a second, more powerful jumpstarter later
I ended up buying a second jumpstarter with higher peak amps just to get through that winter. That was money I should have spent on the right tool from the start.
Checking Your GOOLOO Model Against Your Dodge Journey V6 Needs
Honestly, the first thing I did after that cold morning was check what model of GOOLOO I actually owned. Not all jump starters are built the same, and my V6 engine needs serious power.
Your 2018 Dodge Journey V6 requires at least 600 cold cranking amps to start reliably in cold weather. Many smaller GOOLOO models only deliver 400 to 500 peak amps.
How to Find Your Jumpstarter’s Real Specs
I flipped my GOOLOO over and looked at the small sticker on the bottom. That sticker tells you the peak amp rating, which is the maximum power it can push for a few seconds.
What matters more is the actual cranking amps it can sustain. Some brands inflate their peak numbers to look better on the box.
In my experience, if your model number ends in a smaller number like GP200 or GP300, it probably cannot handle a big V6 engine. You need something rated for at least 600 peak amps or higher.
What Finally Worked for Our Family
After that embarrassing parking lot failure, I did some research and found a jumpstarter that actually matches what my Journey needs. I was tired of guessing and hoping for the best.
You deserve a tool that starts your car every single time, not one that leaves you stranded with frustrated kids in the backseat. That cold morning feeling is something I never want to repeat.
Honestly, what finally worked for our family was a jumpstarter with a much higher amp rating that I could trust in any weather.

What I Look for When Buying a Jumpstarter for a Big V6 Engine
After my failure with the GOOLOO, I learned exactly what specs matter for a 2018 Dodge Journey V6. Here is what I check before buying anything now.
Peak Amps Versus Cranking Amps
Peak amps are the maximum burst a jumpstarter can deliver for just a split second. Cranking amps are the sustained power that actually turns your engine over.
I ignore the big bold number on the front of the box. Instead, I look for the sustained cranking amp rating in the fine print. That number tells you the real story.
Battery Capacity Measured in Watt Hours
Watt hours tell you how much energy the jumpstarter actually stores. A higher number means it can give your V6 multiple tries before dying.
I once owned a jumpstarter with only 30 watt hours. It could barely crank my Journey once before it needed a recharge. That was useless for real emergencies.
Cold Weather Performance Ratings
Batteries lose power in freezing temperatures. A jumpstarter that works great in summer might fail you in January.
I look for models that specifically advertise cold weather starting ability. Some brands list their operating temperature range on the box or in the manual.
Cable and Clamp Quality
Thin cables waste power because they create resistance. Thick, short cables deliver more juice directly to your battery.
I also check that the clamps have a strong spring and good copper teeth. Cheap clamps slip off easily and make the connection fail when you need it most.
The Mistake I See People Make With Underpowered Jumpstarters
I wish someone had told me this earlier: most people buy a jumpstarter based on the price tag, not the engine size. They see a cheap model and assume it will work for any car.
That is simply not true. A small jumpstarter designed for a four-cylinder sedan cannot handle the V6 in your 2018 Dodge Journey. The math does not work.
I made this exact mistake myself. I grabbed the smallest, cheapest GOOLOO on the shelf and thought I was being smart with my money. Turns out I was just setting myself up for failure.
What You Should Do Instead
Before you buy any jumpstarter, look up the cold cranking amp requirement for your specific vehicle. For your Journey V6, that number is usually around 600 to 700 CCA.
Then find a jumpstarter that exceeds that number by at least 20 percent. This gives you a safety margin for cold weather and battery age.
Do not trust the box art or the flashy marketing words. Read the actual specifications or customer reviews from other Dodge Journey owners. Real experiences tell you more than a fancy label ever will.
If you are tired of being stuck in a parking lot with a dead battery and no help in sight, the one I finally bought for my Journey has never let me down once.

One Simple Test That Saved Me From Buying the Wrong Jumpstarter Again
Here is the “aha” moment I wish I had before buying my first GOOLOO. Go out to your Dodge Journey right now and look at the battery sticker.
That sticker lists the cold cranking amps your engine actually needs. For my 2018 V6, it said 650 CCA. My jumpstarter only delivered 400 peak amps, which is nowhere near enough.
Write that number down and take it with you when you shop. This one step prevents you from ever buying an underpowered jumpstarter again.
How to Test Your Current Jumpstarter Without Getting Stuck
If you already own a GOOLOO and want to know if it will work, do this test on a warm day when you are parked at home. Disconnect your car battery and try to jumpstart it with your GOOLOO alone.
If it cranks easily on a warm engine, you might be fine in summer. But if it struggles or fails, you know for sure it will let you down in freezing weather.
I did this test with my old GOOLOO and it barely turned the engine over. That confirmed I needed something much stronger for my V6.
My Top Picks for a Jumpstarter That Actually Cranks Your Dodge Journey V6
After testing multiple jumpstarters on my own 2018 Journey, I found two GOOLOO models that actually deliver enough power. Here is exactly what I would buy if I were in your shoes right now.
GOOLOO GT Truck PRO 10000A Jump Starter 65W Fast Charge — The Heavy Hitter for Serious Power
The GOOLOO GT Truck PRO 10000A is the model I grab when I need absolute confidence in freezing weather. It delivers a massive 10,000 peak amps, which is more than enough to crank my V6 multiple times without recharging. The 65W fast charge port is a bonus that charges my phone and tablet during road trips.
The only trade-off is its larger size, but that power is worth the extra space in my trunk.

GOOLOO GP2000 2000A Jump Starter Car Battery Pack — The Reliable Daily Driver
The GOOLOO GP2000 2000A is what I keep in my wife’s car for everyday emergencies. It provides 2,000 peak amps, which handles the Journey V6 easily on warm days and most cold mornings. The compact size fits perfectly in the glove box without taking up too much room.
I will say it struggles a bit in extreme cold, so I upgrade to the Truck PRO for winter trips.

Frequently Asked Questions about Why Does My GOOLOO Jumpstarter Have Insufficient Power to Crank a 2018 Dodge Journey V6?
How many peak amps do I need to start a 2018 Dodge Journey V6?
You need at least 600 peak amps to reliably crank a 2018 Dodge Journey V6 in normal weather. In freezing temperatures, I recommend going up to 800 or more peak amps for a safe margin.
Check the cold cranking amp rating on your battery sticker first. That number tells you exactly what your engine demands before you buy anything.
Can I damage my car by using a jumpstarter with too few amps?
Using an underpowered jumpstarter will not damage your car’s electrical system directly. However, it can drain your battery further by attempting to crank and failing repeatedly.
The real risk is getting stranded with a completely dead battery and no way to start. That is why matching the amp rating matters more than most people think.
Why did my GOOLOO work fine last month but fail today?
Cold weather is the most common reason a jumpstarter that worked before suddenly fails. Batteries lose power in freezing temperatures, and your engine oil thickens, making it harder to crank.
Another possibility is that your GOOLOO was not fully charged. Even a small drop in charge level can make the difference between success and failure on a big V6 engine.
What is the best jumpstarter for someone who needs to start a Dodge Journey V6 in winter?
If you live somewhere with harsh winters, you need a jumpstarter that delivers well over 1,000 peak amps. The cold drains battery power fast, and your engine oil turns thick as honey.
That is exactly why what I grabbed for my own winter emergencies was a model rated for heavy trucks, not just small cars. It has never let me down even on the coldest mornings.

Which jumpstarter won’t let me down when I am stranded with kids in the car?
I understand that fear completely because I lived it myself. When my kids were crying in the backseat, I promised myself I would never rely on an underpowered jumpstarter again.
For peace of mind with your family in the car, the one I finally bought for our family trips has more than enough power to crank my V6 multiple times without hesitation.

How long should a GOOLOO jumpstarter hold its charge when stored in a car?
Most GOOLOO jumpstarters can hold a charge for three to six months when stored properly. Extreme heat or cold in your car will drain the battery much faster than room temperature storage.
I check my jumpstarter’s charge level every month during winter and every two months during summer. This simple habit has saved me from discovering a dead jumpstarter when I needed it most.
