It was 6 a.m., freezing cold, and my SUV’s battery died—right before a big road trip. That’s when the NOCO Boost HD 12V 2000A stepped in. This wasn’t just a jump starter; it was a lifesaver. I’ve used it on dead batteries, tough engines, and even in the middle of winter—and it never failed me. In this article, I’ll share how it works, how long it takes to charge, and how it compares to models like the NOCO Boost Air AX65 and GB150. I’ll also help you decide if it’s the right fit for you. Let’s dive into my real experience and see if it’s worth it.
What Is the NOCO Boost HD 12V 2000A?
The NOCO Boost HD 12V 2000A is a small jump starter with big power. It sends out 2000 amps, which is strong enough to start gas engines up to 8 liters and diesel engines up to 6 liters. So yes—2000A can jump-start a car, even a large truck or SUV. I’ve done it on cold mornings, and it worked fast.
This jump starter is part of the NOCO Boost line. It’s built for safety and ease. You don’t need to be a car expert to use it. It won’t spark, and it won’t let you hook it up the wrong way. I’ve used it in the dark, in the cold, and even when I was half-awake. It’s that simple.
It does more than just jump-start. I’ve used it to charge my phone and power a tire pump. If you pair it with the NOCO Boost Air AX65, you can inflate tires too. That combo saved me once during a late-night flat. It gave me air and power in one setup.
Now, about the “HD.” It means Heavy Duty. And that’s not just a name. This unit feels tough. I’ve used it on my SUV, a riding mower, and even my neighbor’s old pickup. It handled all of them with no issue.
So, is NOCO Boost a good brand? In my experience, yes. It’s built strong, works every time, and charges fast. I trust it, and I’ve come to rely on it.
If you want a jump starter that’s simple, safe, and strong, the NOCO Boost HD 12V 2000A is a solid pick. It’s one of those tools you don’t think about—until you really need it.
How to Use the NOCO Boost HD GB70 – Step-by-Step
Using the NOCO Boost HD GB70 is simple. I’ve used it in the cold, at night, and even when I was half-asleep.
1. Check the charge
First, press the power button. A light bar will turn on. Four lights mean it’s fully charged. One light means it’s almost dead. If it’s low, plug it in with a USB-C cable. I use a wall charger to make it quick. Once, I topped it up in under an hour.
2. Hook up the clamps
Open the hood and find the battery. Clip the red clamp to the + terminal. Then, clip the black clamp to the – terminal. If you mess up and swap them, it’s okay—the safety tech stops sparks and damage. That’s why I trust it, even when I’m not thinking straight.
3. Power it on and start the engine
Push the power button on the unit. The white lights will flash. That means it’s ready. Go inside your car and turn the key or push the start button. I’ve done this on my SUV in the middle of winter—it started in seconds without any help.
4. Remove the clamps and pack up
Once the car is running, take off the black clamp first, then the red. Put the clamps back in the case and stash it in your car. The whole process takes under five minutes. It’s faster than calling for help or waiting for roadside service.
Tips for cold weather
If you live where winters are rough, don’t leave the unit in your garage. Cold batteries lose power fast. I keep mine in my truck’s cab so it stays warmer. That small change helped me get a reliable start even when it was below zero.
Mistakes to avoid
Don’t press the Boost button unless your battery is totally dead and the unit won’t turn on by itself. In most cases, the GB70 kicks in on its own. I’ve only had to use Boost once, and that was on an old mower that hadn’t run in months.

How Long Does It Take to Charge the NOCO Boost HD 12V 2000A?
Charging the NOCO Boost HD 12V 2000A is fast—about 3 to 5 hours with a wall charger, or under an hour with a 60W USB-C fast charger. I’ve used both. The wall plug is solid, but the USB-C is lightning quick.
One time, I forgot to charge mine for weeks. It sat in the back of my truck through a cold snap. When my battery died one morning, I figured I was stuck. But I hit the power button, saw two lights, and gave it a shot. My SUV started right up. Even with a low charge, it still worked.
You can also charge it with your car’s 12V outlet. But it takes longer—about 6 hours in my tests. Still, it’s a good backup while driving.
Now, I just charge it once a month—like I check my tire pressure. I plug it in during breakfast. It’s that simple. Knowing it’s full gives me peace of mind, especially before road trips.
So, how long does it take to charge a NOCO Boost HD 12V 2000A? Not long. Use a fast charger when you can. Keep it topped off, and you’ll be ready whenever your battery isn’t.
Real-World Performance: My Experience Jump-Starting & Inflating
One cold morning, my SUV wouldn’t start. The battery was dead. I grabbed the NOCO Boost HD 12V 2000A, hooked it up, and pressed the button. The engine started in seconds. Yes, 2000A is strong enough to jump-start a big SUV—even in freezing weather.
Since then, I’ve used it many times. I’ve started trucks, mowers, and even my neighbor’s old van. It works fast and never lets me down. It handles gas engines up to 8.0L and diesel engines up to 6.0L. I’ve tested both.
Now let’s talk about tires. I once had a slow leak in winter. My small pump was loud and slow. I tried the NOCO Boost Air AX65, which has a built-in air pump. It worked great. It pushes out 100 PSI and 22A. It topped off my tires in about 10 minutes. That’s fast and easy, even when it’s cold.
If you want a jump starter and an inflator in one, the AX65 is a smart pick. It’s a bit bigger, but it saves space and stress. I use the HD in my daily SUV, and the AX65 in my camping truck.
For power, both the HD and AX65 feel the same when jump-starting. But the AX65 wins for tires. It’s faster than most small pumps and more reliable.
I’ve also tried the GB150—too big unless you drive heavy-duty trucks. The GB40 is great for small cars but lacks the power for trucks. The GB70 hits the sweet spot. It’s small, strong, and fits in your glove box.
Bottom line? The NOCO Boost HD 12V 2000A is strong, fast, and safe. If you need tire help too, go with the AX65. Both are solid choices.
What’s Included in the Box (and What You’ll Actually Use)
When I first opened the NOCO Boost HD 12V 2000A box, I felt like I was unboxing a high-end gadget. Everything was packed tight and clean. You get the jump starter itself, heavy-duty clamps, a USB-C charging cable, a 12V car charger, and a soft carrying bag.
Short answer: The NOCO Boost HD 2000A includes clamps, cables, a carry case, and a USB-C cord—everything you need to get started right away.
The clamps are thick and strong. These aren’t the flimsy kind that slip or spark. They grip the battery tight, even when your hands are cold or you’re rushing in the rain. The USB-C cable is solid too—it’s not super long, but it gets the job done fast with a proper charger.
The carry case is soft-sided and has just enough room for the unit and cables. I do wish it was hard-shell, but I haven’t had any issues keeping it behind my truck seat or in my cargo bin. It stays put, even on bumpy roads.
Now, let’s talk about what I actually keep in my car with it. Alongside the NOCO, I carry a small tire pressure gauge, a flashlight, and a phone charging cable. The NOCO has a USB out port, so I’ve used it more than once to charge my phone on the road. It’s surprisingly handy.
Quick insight: If you keep a few key accessories with your NOCO—like a flashlight, tire gauge, and phone cord—you’ll be ready for just about anything on the road.
I also added a wall charger to my kit. The NOCO doesn’t come with one, but I use my 60W USB-C phone charger. It tops it off in under an hour. Worth it, especially if you’re in a hurry.
One more thing—if you’re the type who likes to be ultra-prepared, grab a mini air pump or pair it with the NOCO Boost Air AX65. That setup saved me once when I had a slow leak after a road trip. It’s peace of mind in a pouch.
Bottom line: You get all the essentials in the box, but a few extras—like a flashlight and wall charger—make it even better.

Pros and Cons – From Daily Use
Let’s talk about what I love—and what I don’t—after using the NOCO Boost HD 12V 2000A for over a year.
✅ Pros
It’s got real power.
This little box can jump-start a full-size SUV in the dead of winter. I’ve done it more than once. It’s strong and fast—just what you need when your battery gives up.
It’s small but mighty.
It fits behind my truck seat. No mess, no bulk. I don’t have to move stuff around to make room for it. Just grab it and go.
It charges fast.
With a good USB-C wall charger, I get a full charge in under an hour. That’s fast enough to plug it in during breakfast and hit the road fully charged.
It’s foolproof.
NOCO’s UltraSafe tech means no sparks, even if you mess up the clamps. I’ve done that before—clipped the wrong side—and it didn’t freak out. It just blinked a warning. That gives me peace of mind, especially when I’m tired or cold.
❌ Cons
It’s not cheap.
You’re paying for quality—and it shows—but it’s not a budget buy. Still, I’d rather spend more once than deal with cheap jump starters that fail when you need them.
No air pump built in.
If you want to inflate tires, you’ll need a separate inflator or upgrade to the NOCO Boost Air AX65. That one has a built-in compressor and saves space.
It needs regular charging.
I’ve learned to top it off once a month. It holds a charge well, but if you forget for too long, you’ll be out of luck. Keep a USB-C cable handy and you’re golden.
Bottom line?
The NOCO Boost HD 12V 2000A is a reliable tool I trust. It’s strong, safe, and easy to use. Yes, it has a few downsides—but for me, the pros win every time.

NOCO Boost HD GB70 vs. AX65 vs. GB150 vs. GB40
I’ll be honest—when I first saw all the NOCO models, I was lost. They all looked strong. But each one is made for a different job.
Let’s break it down real quick:
| Model | Power | Best For | Tire Pump | Weight | Price |
| GB40 | 1000A | Small cars | ❌ | 2.4 lbs | $99–$125 |
| GB70 HD | 2000A | Trucks, SUVs | ❌ | 5 lbs | $150–$200 |
| AX65 | 2000A | Jump + Tire Pump | ✅ | 6+ lbs | $180–$300 |
| GB150 | 3000A | Diesel, RV, big gear | ❌ | 7.5 lbs | $275–$350 |
Fast answer?
If you drive a truck or SUV, get the GB70. It has strong power. It’s not too big. It fits behind the seat. I keep one in mine.
If you want a tire pump too, grab the AX65. I used it after a camping trip. One tire was low. It filled fast—even in the cold.
The GB150 is for big jobs. It works on RVs and diesel trucks. I used it once on a box truck. It started right away. But it’s heavy.
The GB40 is for small cars. Great if you drive a sedan or hatchback. My friend has one in his Honda. It’s cheap and easy to use.
Need help picking?
- Big truck or SUV? Get the GB70.
- Want a pump too? Go with AX65.
- Diesel or RV? Choose the GB150.
- Just need a boost? GB40 is solid.
I’ve tested all four. They all work. Just pick what fits your ride and your space.
