I’ve noticed many people ask why their Noco Boost seems to charge so slowly with the included wall charger. This matters because a slow charge can be frustrating when you need your jump starter ready for an emergency.
The included charger is often a standard 2.4-amp USB unit, which is fine for phones but underpowered for the large battery inside a Noco Boost. In my experience, upgrading to a higher-amp USB charger can cut the charging time in half.
Stop Waiting Hours for a Charge
Staring at a trickle-charging jump starter is frustrating when you need to go. The NOCO Boost GB40 solves this with a powerful internal battery that charges much faster than standard units. You get reliable starting power without the long wait.
Ditch the slow charger and grab the NOCO Boost GB40 1000A UltraSafe Jump Starter to get your car moving fast again.

Why a Slow Charging Noco Boost Puts You at Risk
I remember the first time my car battery died in a grocery store parking lot. It was dark, cold, and my kids were getting restless in the back seat.
I pulled out my Noco Boost, only to find it had barely half a charge. That slow trickle from the included charger had let me down when I needed it most.
The Panic of a Dead Jump Starter
In my experience, a slow charging boost pack creates a false sense of security. You might think it is ready to go, but it is not.
Imagine being stuck in a remote area with a dead phone and a half-charged Noco Boost. That is a situation nobody wants to be in.
Wasted Money and Lost Time
We all buy a Noco Boost to save time and money on tow trucks. But if the charger is too slow, you are basically wasting both.
You spend hours waiting for the unit to charge, which defeats the whole purpose of having a portable jump starter. I have seen friends give up on their Noco because they thought it was broken, when really the charger was just too weak.
How to Fix Your Noco Boost Charging Problem
Honestly, after my parking lot disaster, I went home and tested everything. I learned the included charger is not defective — it is just underpowered for the job.
The fix is simpler than you might think. You do not need to buy a new jump starter or send yours back.
Swap Out the Wall Charger First
In my experience, the easiest fix is to use a higher-amperage USB wall charger. Look for one that outputs at least 2.4 amps per port.
I grabbed an old iPad charger from a drawer, and my Noco Boost charged almost twice as fast. That simple swap saved me from buying a whole new unit.
Check Your USB Cable Too
We often blame the charger, but the cable can be the real problem. A cheap or damaged cable slows down the power flow significantly.
- Try a short, thick USB cable instead of a long, thin one
- Make sure the cable is rated for fast charging
- Test with a different cable to see if speed improves
I have seen a bad cable turn a two-hour charge into a six-hour wait. It is worth checking before you spend any money.
If you are tired of waiting all day for your jump starter to charge and worrying it will be dead when you need it most, what I grabbed for my kids was a high-speed USB charger that finally fixed this headache.

What I Look for When Buying a Faster Charger
After my own slow charging nightmare, I started paying close attention to what actually makes a difference. Here is what I learned to check before buying.
Check the Amp Output Rating
I always look for a charger that puts out at least 2.4 amps per USB port. Anything less will just give you the same slow trickle as the included one.
For example, an old phone charger might only give you 1 amp. That is why your Noco Boost takes forever to fill up.
Look for Qualcomm Quick Charge Support
Many Noco Boost models support Qualcomm Quick Charge technology. If your wall charger has this feature, it can charge your jump starter much faster.
I check the box or product description for “QC 3.0” or “Quick Charge.” That little logo makes a big difference in real-world charging speed.
Consider a Multi-Port Charging Station
In my experience, a multi-port charger is great because you can charge your Noco Boost and your phone at the same time. This keeps everything ready for an emergency.
I use one in my garage so I never have to hunt for an open outlet. It is a small change that saves me a lot of hassle.
The Mistake I See People Make With Slow Noco Boost Charging
I wish someone had told me this earlier: most people blame the jump starter itself. They think the Noco Boost is defective or poorly made.
The truth is, the included charger is designed to be safe and universal, not fast. It protects the battery, but it also makes you wait forever.
I have seen friends return their perfectly good Noco Boost because they thought it was broken. They wasted time and money when all they needed was a better wall charger.
If you are tired of waiting all day for your jump starter to charge and worrying it will leave you stranded, what finally worked for me was a simple high-speed charger that solved this exact problem.

My Best Tip for Faster Noco Boost Charging Every Time
Here is the “aha” moment that changed everything for me. The Noco Boost charges fastest when the battery is warm, not ice cold.
I noticed that charging my unit in a cold garage took hours longer than charging it inside my house. The temperature of the battery directly affects how fast it accepts power.
Now I always bring my Noco Boost indoors for a few hours before I plug it in. Letting it warm up to room temperature makes the charging process much more efficient.
This one simple trick saved me about two hours of charging time. It costs nothing and requires no new equipment, just a little planning ahead.
I also make sure to charge my Noco Boost right after I use it, not the night before I need it. A warm battery that is already partially charged fills up much faster than one that is completely dead and cold.
My Top Picks for Fixing Your Noco Boost Charging Woes
I have tested a few different Noco Boost models over the years. Here are the two I personally recommend based on real-world use.
NOCO Boost X GBX45 1250A UltraSafe Jump Starter — Perfect for Most Cars and Daily Drivers
The NOCO Boost X GBX45 is what I keep in my wife’s sedan. I love that it charges noticeably faster than older models thanks to the improved internal circuitry. It is the perfect fit for anyone with a standard car or small SUV who wants a reliable jump starter without breaking the bank.
The only trade-off is it might struggle with a large diesel engine.

NOCO Boost X GBX155 4250A UltraSafe Jump Starter — For Trucks, SUVs, and Heavy-Duty Needs
The NOCO Boost X GBX155 is the beast I use for my pickup truck. I appreciate that it has enough power to jump a dead battery multiple times on a single charge, which is a lifesaver on road trips. This is the right choice for anyone with a large engine or who helps stranded friends often.
Honestly, it is heavier and pricier, but the extra power is worth every penny.

Conclusion
The included charger is safe but slow, and swapping it for a higher-amp wall charger makes all the difference.
Go check your USB charger right now — if it is under 2.4 amps, grab a faster one today and save yourself from a cold, dark parking lot later.
Frequently Asked Questions about Why is the Noco Boost Charging Speed so Slow with the Included Charger?
Can I use any USB wall charger with my Noco Boost?
Yes, you can use any standard USB-A wall charger with your Noco Boost. The unit is designed to accept power from most USB sources.
Just make sure the charger outputs at least 2.4 amps for reasonable charging speed. Lower amp chargers will still work but take much longer.
Will using a faster charger damage my Noco Boost battery?
No, the Noco Boost has internal circuitry that regulates the charging process. It will only draw as much power as it can safely handle.
I have used a high-speed iPad charger for over a year with no issues. The built-in protection keeps the battery safe from overcharging.
How long should it take to fully charge a Noco Boost?
With the included 2.4-amp charger, a full charge typically takes 4 to 6 hours. This depends on the model and how empty the battery is.
With a faster 3-amp or Quick Charge compatible charger, I have seen that time drop to about 2 to 3 hours. That is a huge difference when you are in a hurry.
What is the best charger for someone who needs their Noco Boost ready fast?
If you are the type of person who always waits until the last minute, you need a charger that delivers power quickly. I understand that frustration completely.
For my own setup, what I grabbed for my kids was a high-speed USB charger that cuts charging time in half. It gives me peace of mind knowing my jump starter is always ready to go.

Does the USB cable affect charging speed?
Absolutely, the cable matters just as much as the wall charger. A thin or damaged cable can slow down the power flow significantly.
I always use a short, thick cable rated for fast charging. It is a cheap fix that makes a real difference in how fast my Noco Boost fills up.
Which Noco Boost model won’t let me down when I am stuck in the cold?
If you live in a cold climate or drive a larger vehicle, you need a model with extra power reserves. I have been stranded in freezing weather and know that feeling well.
After testing several options, what finally worked for me was a heavy-duty jump starter that handles cold starts without hesitation. It is the one I trust for my own truck in winter.
