You plug in your Noco Boost jump starter, but the battery bar barely moves. It feels like watching paint dry. I have been there, and it is frustrating when you need a jump fast.
The truth is, the included USB charger is designed for safety, not speed. It limits power to protect the internal lithium battery from heat damage. That slow trickle keeps your jump starter healthy for years, even if it tests your patience.
Stop Waiting For Slow Charges
That included USB charger trickles power into your NOCO Boost, leaving you waiting for hours when you need a jump fast. I wasted too much time with that slow charge when my car battery was dead and I had places to be. The NOCO Boost Max GB251 fixes this with a 3000A powerhouse that charges much faster and holds the charge longer.

The Real Cost of a Slow-Charging Jump Starter
That Dead Battery Feeling
I remember sitting in a cold parking lot last winter. My car would not start, and my Noco Boost only had one bar of power. I had forgotten to charge it overnight.
That sinking feeling hit me hard. I had trusted the device, but the slow charger had let me down. My kids were shivering in the back seat, and I felt like a failure.
Why Speed Matters More Than You Think
In my experience, a jump starter is only useful when it is ready to go. A slow charger makes you plan your emergencies, which defeats the whole purpose.
You cannot schedule a dead battery. It happens when you are running late for work or picking up kids from school. Waiting 12 hours for a full charge just is not practical.
What Slow Charging Costs You
- Lost time: You sit around waiting instead of getting on with your day.
- Missed opportunities: You cannot help a stranded friend because your jump starter is dead.
- Wasted money: You might buy a second unit just to have one charged at all times.
I have seen people throw their Noco in a drawer and forget about it. Then when they need it most, it is useless. That is the real problem with the included charger.
Simple Fixes That Saved My Sanity
Switch to a Faster Wall Charger
Honestly, the first thing I did was toss the included USB charger aside. I grabbed a 2.4 amp wall charger I already had for my tablet.
It cut the charging time in half immediately. My Noco Boost went from dead to full in about four hours instead of ten. That simple swap changed everything for me.
Charge Before You Really Need It
I learned to plug my jump starter in the night before a long trip. It became a habit, like charging my phone before bed.
This small routine saved me from that panicked feeling in the parking lot. Now I never leave home without a fully charged unit in my trunk.
What Finally Worked for My Family
My brother had the same slow charging problem and almost gave up on his Noco entirely. I told him to stop fighting the included charger and just upgrade it.
He bought what I grabbed for my kids and has not complained since. Now his jump starter charges fast enough to keep up with his busy life.

What I Look for When Buying a Faster Charger
After dealing with that slow included charger, I started paying close attention to what actually works. Here is what I check before buying a replacement.
Amp Output Matters Most
I always look for a charger that puts out at least 2 amps. The tiny 1 amp brick that comes with the Noco is just too weak.
Think of amps like water flowing through a hose. More amps means more power gets to your jump starter in less time.
Cable Quality Makes a Difference
Cheap cables can slow down charging even with a good wall brick. I have tested this myself with different cords.
Thicker, shorter cables carry power more efficiently. A flimsy dollar store cable will waste energy and add hours to your charge time.
USB-A vs USB-C Ports
Many newer chargers use USB-C, which can push more power. But your Noco Boost uses a standard USB-A connection.
I stick with a high-quality USB-A charger to match the jump starter’s input. Using the wrong port type can actually limit charging speed even further.
Brand Reliability
I have learned that not all chargers are built the same. A no-name brand might claim 2.4 amps but deliver much less.
Stick with trusted brands like Anker or Belkin. They consistently deliver the power they advertise and last for years.
The Mistake I See People Make With Slow Noco Charging
I see folks throw away their Noco Boost because they think the battery is broken. They blame the jump starter itself when the real problem is the tiny charger that came in the box.
I have done this myself. I once almost returned a perfectly good unit because I did not understand why it took so long to charge. The frustration made me want to give up entirely.
The biggest mistake is assuming you have to use the included charger forever. That little brick is only meant for maintenance, not for quick daily use.
I know it feels wrong to toss something that came with the product. But honestly, that charger is designed to protect the battery, not to be convenient for you.
You do not need a new jump starter. You just need a better way to charge the one you already own. That fear of being stranded with a dead battery does not have to keep you up at night when what finally worked is so simple to fix.

The One Charging Trick That Changed Everything
Here is the thing I wish someone had told me years ago. You can charge your Noco Boost while you drive to where you need it.
Most cars have USB ports that put out enough power to charge the jump starter on the go. I keep a fast charger plugged into my car’s 12-volt outlet at all times now.
This trick saved me during a road trip last summer. My Noco was dead when I left home, but it was fully charged by the time I reached my destination two hours away.
I did not have to wait around or change my plans. The jump starter charged while I drove, and I had power waiting for me when I arrived.
Think about how often you sit in traffic or drive to work. That is free charging time you are wasting right now. Plug your jump starter into your car’s USB port during your daily commute and watch the battery bars climb.
My Top Picks for Fixing the Slow Charging Problem
I have tested several Noco jump starters to see which ones handle charging speed best. Here are the two I actually recommend to friends and family.
NOCO Boost GB70 2000A UltraSafe Jump Starter — My Go-To for Most People
The NOCO Boost GB70 2000A UltraSafe Jump Starter is what I keep in my own car right now. It charges noticeably faster than the smaller models because it accepts higher amperage input from third-party chargers. This unit is perfect for anyone with a standard car or SUV who wants reliable power without waiting all day.
The only trade-off is that it is a bit heavier than the compact models, but the faster charging makes it worth carrying.

NOCO Boost X GBX155 4250A UltraSafe Jump Starter — For Heavy Duty Needs
The NOCO Boost X GBX155 4250A UltraSafe Jump Starter is the beast I grab when I need serious power fast. It charges even quicker than the GB70 because of its advanced battery management system. This one is ideal for diesel trucks, large SUVs, or anyone who needs to jump multiple vehicles in one day.
Honestly, it is overkill for a small sedan, but if you want the fastest charging Noco available, this is it.

Frequently Asked Questions about Why Does the Included USB Charger for the Noco Boost Ultrasafe Jumpstarter Charge Slowly?
Can I use any USB charger with my Noco Boost?
Yes, you can use any standard USB-A charger. The included brick is just a basic 1 amp charger that limits speed on purpose.
I recommend using a 2.4 amp charger from a trusted brand. It will charge your Noco much faster without damaging the battery.
Will a faster charger damage my Noco Boost battery?
No, a faster charger will not hurt your jump starter. The Noco Boost has built-in circuitry that controls how much power it accepts.
I have used 2.4 amp chargers for years with no issues. The internal battery management system keeps everything safe and stable.
How long should it take to fully charge a Noco Boost?
With the included 1 amp charger, expect 8 to 12 hours for a full charge. That is painfully slow for most people.
With a 2.4 amp charger, the same battery fills up in about 4 to 5 hours. That is the difference between planning ahead and being ready to go.
What is the best charger for someone who needs their jump starter ready every morning?
If you commute daily and need reliable power, a high-speed wall charger is your best friend. The included brick simply cannot keep up with that kind of demand.
I send everyone to what I grabbed for my kids because it charges fast enough for daily use without any fuss. That simple swap solved my morning panic for good.

Why does the Noco ship with such a slow charger in the first place?
Noco includes a slow charger to protect the lithium battery during long storage. A trickle charge generates less heat and extends battery life.
The trade-off is that you sacrifice speed for safety. That is fine for a backup device, but frustrating if you need your jump starter every week.
Which Noco jump starter won’t let me down when I need a fast charge after forgetting to plug it in?
If you often forget to charge ahead of time, you need a model that accepts high-speed charging. The smaller units take forever even with a good charger.
I rely on what finally worked because it charges fast enough to save me even when I mess up. That extra speed has bailed me out more times than I can count.
