My car battery died in the middle of nowhere. No help, no signal, just me and my dead car. But the NOCO Boost HD GB70 saved the day. If you’re wondering how to use the NOCO Boost HD GB70, I’ve got you covered. I’ll show you exactly how it works, share my real experience, and answer the questions you’re probably asking. Let’s get started, so you’re ready when it counts!
What Is the NOCO Boost HD GB70?
The NOCO Boost HD GB70 is a powerful jump starter. It gives you 12 volts and up to 2000 amps of power. In simple terms, it can start most cars, trucks, boats, and even big SUVs.
What I love most is how easy it is to carry. It’s small enough to fit in your trunk but strong enough to save the day. Plus, it has safety features built in. You don’t have to worry about sparks or hooking it up wrong. The device tells you if something’s not right.
You might also see it called the NOCO Boost HD 12V 2000A. That’s just another way to say it’s made for 12-volt batteries with 2000 amps.
Now, you might wonder: Is the GB70 the best one? Well, it depends. There’s also the NOCO Boost X GBX155. It’s a bit stronger and has newer tech. But for most drivers, the GB70 is more than enough. It’s the one I keep in my car, and it hasn’t let me down.
Step-By-Step: How to Use NOCO Boost HD GB70
3.1 Before You Start: Safety First
Before you start, do a quick safety check. Trust me, it’s worth it.
Make sure the NOCO Boost looks good. No damage. No loose wires. Check the clamps too—clean and tight is best. Put your car in park. Turn the key off. Take a look around. No water. No sparks. No funny smells.
👉 My tip: I keep a small flashlight in my glove box. It’s a lifesaver at night.
The NOCO GB70 has built-in safety. It won’t work if something’s wrong. You won’t get sparks or shocks.
If you want more info, the NOCO Boost HD GB70 manual is super clear. I actually read it. It’s rare, but this one’s helpful.
3.2 Step 1: Check the Charge
First, hit the power button.
You’ll see up to four white lights. That tells you how much charge is left.
- Four lights: full power.
- Three: 75%.
- Two: 50%.
- One: charge it now.
- Blinking? It’s charging.
👉 How do I know when my NOCO GB70 is fully charged?
When all four white lights stay solid, it’s full.
I plug mine in after every use. That way, it’s ready when I need it.
3.3 Step 2: Connect to the Battery
Now, open the hood. Find your car battery.
Connect the red clamp to the positive (+) side. The black clamp goes on the negative (–) side.
When it’s hooked up right, the GB70 shows a green light. That means it’s safe to go.
👉 What if the battery is totally dead?
If the car has zero power, use manual override. Hold the red exclamation button for 3 seconds. The white Boost light will turn on. That tells the unit to send power.
This saved me once when my old truck had nothing. Not even a dash light. The override worked fast.
3.4 Step 3: Jump Start Process
Next, press the Boost button.
The white light will turn on. Now try to start your car.
It should start fast. If not, wait 30 seconds and try again.
👉 What if you hear a clicking sound?
That means the clamps may not be tight. Or the unit is in safe mode. Check the cable ends. I had this once—it was just a dirty battery post. I cleaned it, and the car started.
3.5 Step 4: After the Jump
Your car is running? Great. Time to finish up.
First, remove the black clamp. Then the red one. Don’t let the clamps touch metal.
Turn off the NOCO Boost. Wait a minute before putting it away.
👉 Now recharge it.
Jumping drains the battery. Plug it into the wall or your car’s 12V outlet. I always top it off so I don’t get caught off guard.

Can NOCO Boost Jump a Completely Dead Battery?
Yes, it can. I’ve done it.
One cold day, I turned the key. Nothing. No lights. No clicks. My car was dead. Not low—fully dead.
I grabbed my NOCO Boost HD GB70. Hooked it up. Still nothing. That’s when I used the manual override.
➡️ Will NOCO Boost jump a completely dead battery?
Yes, if you use manual override.
Hold the red (!) button for 3 seconds. You’ll see a white Boost light. That means it’s sending power. Try the key again. Boom—my car started!
This trick saved me more than once. It works even when your battery has zero power.
Tip: Always check the light on the NOCO. It tells you what’s happening. If it’s not ready, hit override.
So yes, the NOCO GB70 can jump a dead battery. Even when it’s completely out of juice.
Charging the NOCO Boost HD GB70
After I use the NOCO GB70, I charge it right away. I don’t wait. I want it full the next time I need it.
➡️ How do you charge the NOCO Boost HD GB70?
Use the cord that comes with it. Plug it into a wall or your car’s 12V port. Press the power button. The white lights will show the charge.
- 4 lights = full
- 3 = 75%
- 2 = 50%
- 1 = low
- Blinking = it’s still charging
When all four lights stay on, it’s full. Easy.
Tips That Help Me
Here’s what I do to keep mine ready:
- Charge it after each use
- Use a wall plug—it’s fast
- Keep it cool and dry
➡️ How long does it take to charge?
With a wall plug, mine takes 6–7 hours. In the car, it takes more time.
I just plug it in at night. By morning, it’s done. No stress.
NOCO Boost HD GB70 Charging Problems
One time, mine didn’t charge. No lights. I thought it was dead.
➡️ What if your NOCO GB70 won’t charge?
First, try a new cord. Then, try a new plug. Still no luck? Hold the power button for 10 seconds. That resets it.
Check the port too. Mine had sand in it once. A toothpick cleaned it out. Worked great.
➡️ Use the right charger.
Use one with at least 2.1 amps. Weak plugs won’t work well.
Still stuck? Call NOCO. Their help team is fast and nice. They fixed my issue in one call.

NOCO GB70 Review – My Honest Thoughts
I’ll be real with you—the NOCO GB70 saved my butt more than once.
One time, my truck died on a cold morning. No lights, no clicks. Just silence. I grabbed the NOCO, clamped it on, hit Boost, and boom—started right up. That’s why I keep it in my trunk.
➡️ Is the NOCO GB70 worth it?
Yes. It’s easy, safe, and works fast—even on dead batteries.
What I Like
- It’s strong. It started my truck without a problem.
- It’s simple. Just clamp, press, and go.
- It’s safe. No sparks. No shocks.
- It’s small. Fits in my trunk with room to spare.
- It’s quick to charge. Wall charging is fast.
I also used it to charge my phone. Once, I even ran a tire inflator with it.
➡️ Can you use the NOCO GB70 for other stuff?
Yes. It can power phones, lights, or small tools with the USB port.
What I Don’t Like
- No wall charger in the box. You need your own plug.
- Clamps are stiff. They loosen after a few uses.
- Car charging is slow. Wall charging is better.
Still, none of this is a dealbreaker. I’ve tried cheap jump starters. They failed when I needed them most. The NOCO never did.
GB70 vs. GBX155
➡️ What’s the difference?
The GBX155 has more power and faster charging. But it costs more.
- GB70 = great for most people.
- GBX155 = best for big engines or daily use.
I chose the GB70. It’s strong and easy to use. Two years later, it still works like new.
Where to Buy & Best Price Tips

I got mine from Amazon. It was fast and easy. You can also check Walmart or NOCO’s official site. These are the best places to find the real thing.

➡️ How much does the NOCO GB70 cost?
Most times, it costs between $160 and $200. If you see it for less than $150, that’s a great deal. Over $200? I’d wait for a sale.
