Understanding Your Noco Jump Starter

Before we dive into the charging process, it’s important to understand what a Noco jump starter is and how it works. Noco is a leading brand in portable power solutions, known for their high-quality, reliable jump starters that can revive dead car batteries in minutes. These devices are essentially compact lithium-ion batteries with built-in safety features, designed to deliver a powerful burst of energy to your vehicle’s battery.

What Makes Noco Jump Starters Different?

Unlike traditional jumper cables that require another vehicle, Noco jump starters are self-contained units. They store electrical energy and release it when needed, making them perfect for emergencies. Most models come with additional features like USB ports for charging phones, LED flashlights, and even air compressors in some cases. But all of these features rely on one thing: a fully charged internal battery.

The key to their reliability lies in the lithium iron phosphate (LiFePO4) or lithium-ion (Li-ion) battery technology used. These batteries are lightweight, have a long lifespan, and can hold a charge for months—when properly maintained. However, they still need to be recharged periodically, especially if you haven’t used the device in a while.

Common Noco Jump Starter Models

Noco offers a range of jump starters, from compact models like the GB20 (500 peak amps) to heavy-duty ones like the GB150 (4000 peak amps). While the charging process is similar across models, the time it takes and the power source may vary slightly. Here’s a quick overview:

• GB20: Ideal for small cars and motorcycles. Charges in about 3 hours.
• GB40: Great for sedans and SUVs. Charges in 3–4 hours.
• GB70: Designed for larger vehicles like trucks and vans. Charges in 4–6 hours.
• GB150: A powerhouse for commercial vehicles and large engines. Charges in 6–8 hours.

No matter which model you have, the charging principles remain the same. The next section will break down exactly how to charge your Noco jump starter safely and efficiently.

How to Charge Your Noco Jump Starter: Step-by-Step

Charging your Noco jump starter is straightforward, but doing it correctly ensures maximum performance and longevity. Let’s walk through the process step by step.

Step 1: Locate the Charging Port

First, find the charging port on your jump starter. On most Noco models, it’s a small DC input port, usually labeled “DC IN” or “Charge.” It’s typically located on the side or back of the unit, near the power button and LED indicators. Make sure the device is turned off before plugging anything in.

Step 2: Use the Correct Charging Cable

Your Noco jump starter comes with a dedicated charging cable—usually a DC barrel plug or USB-C, depending on the model. Never use a random cable you find lying around. Using the wrong cable can damage the battery or result in a slow, inefficient charge. For example, the GB40 uses a DC input, while newer models like the GB70 may support USB-C fast charging.

Pro tip: Keep the original charging cable in your glove compartment or with the jump starter. It’s easy to lose, and replacements aren’t always compatible.

Step 3: Plug Into a Power Source

Now, plug the other end of the cable into a power source. This can be:

• A standard wall outlet (110V in the U.S.)
• A car’s 12V cigarette lighter socket (using an adapter)
• A portable power station or solar charger (for off-grid use)

Wall outlets are the fastest and most reliable option. Charging via a car’s cigarette lighter is convenient but slower and may not work if your car’s battery is also low. Avoid using extension cords with low-gauge wires, as they can reduce charging efficiency.

Step 4: Monitor the Charging Indicators

Once connected, your Noco jump starter will display charging status through LED lights. Most models have a series of lights that blink or change color as the battery charges. For example:

• Red light: Charging in progress
• Green light: Fully charged
• Flashing red: Error or connection issue

It’s normal for the lights to cycle through different patterns. If the red light stays solid or flashes repeatedly, double-check the connections. Make sure the cable is fully inserted and the power source is active.

Step 5: Wait for a Full Charge

Charging times vary by model and battery capacity. On average, it takes 3 to 6 hours to fully charge a Noco jump starter from empty. Here’s a quick reference:

Model	Battery Capacity	Charging Time (Wall Outlet)
GB20	5,000mAh	3 hours
GB40	10,000mAh	4 hours
GB70	18,000mAh	6 hours
GB150	40,000mAh	8 hours

Don’t rush the process. Charging too quickly with an incompatible power source can overheat the battery and shorten its lifespan. Patience pays off here.

Step 6: Unplug and Store Properly

Once the green light appears, unplug the charger immediately. Leaving it plugged in for extended periods won’t overcharge the battery (thanks to built-in protection circuits), but it’s still good practice to disconnect. Store your jump starter in a cool, dry place—away from direct sunlight or extreme temperatures.

And remember: even if you don’t use your jump starter often, it’s wise to recharge it every 3 to 6 months to maintain battery health.

Alternative Charging Methods

While wall outlets are the go-to method, there are times when you might need to charge your Noco jump starter on the go. Let’s explore some alternative charging options.

Charging in Your Car

Yes, you can charge your Noco jump starter using your car’s 12V cigarette lighter socket. This is especially useful during road trips or if you’re away from home. However, there are a few caveats:

• Your car’s engine should be running to provide stable power.
• Charging will be slower than using a wall outlet—expect 50–70% longer charging times.
• If your car battery is weak, it may not provide enough power to charge the jump starter effectively.

To charge via car, use the included DC adapter cable. Plug one end into the jump starter’s charging port and the other into the cigarette lighter. Keep an eye on the LED indicators to ensure it’s charging properly.

Using a Portable Power Station

If you’re camping or in a remote area, a portable power station can be a lifesaver. These devices store solar or grid energy and can power your jump starter via AC or DC output. Just make sure the power station has enough capacity—ideally 100Wh or more—to fully charge your Noco unit.

For example, a 200Wh power station can charge a GB40 jump starter about 1.5 times. Always check the wattage and compatibility before connecting.

Solar Charging (With Limitations)

Solar panels can charge your jump starter, but it’s not the most efficient method. Most portable solar panels output 10–20 watts, which means it could take 10–20 hours to fully charge a GB40. This is only practical if you have days of sunlight and no other power source.

If you do go solar, use a charge controller to prevent overcharging and connect the panel to a power bank first, then charge the jump starter from the bank. This adds stability and protects the battery.

How Long Does a Noco Jump Starter Hold a Charge?

One of the biggest advantages of Noco jump starters is their ability to hold a charge for months. But how long exactly?

Battery Longevity and Self-Discharge

Most Noco jump starters use lithium iron phosphate (LiFePO4) or high-quality lithium-ion batteries, which have low self-discharge rates. This means they lose only about 2–5% of their charge per month when not in use. So, if you fully charge your GB40 and store it properly, it should still have 80–90% charge after 6 months.

However, extreme temperatures can accelerate self-discharge. Storing your jump starter in a hot car trunk or freezing garage can reduce its shelf life. Ideal storage temperature is between 32°F and 77°F (0°C to 25°C).

Signs Your Jump Starter Needs a Charge

Even with low self-discharge, it’s smart to check your jump starter periodically. Here are signs it might need a recharge:

• The power button doesn’t light up when pressed.
• The LED indicators flash or behave erratically.
• It fails to jump-start your vehicle (even with correct connections).
• It’s been more than 6 months since the last charge.

Most Noco models have a built-in battery test feature. Press and hold the power button for a few seconds to see the charge level. If only one or two lights appear, it’s time to recharge.

Maximizing Battery Life

To get the most out of your jump starter’s battery:

• Recharge every 3–6 months, even if unused.
• Avoid draining the battery completely—try to recharge when it hits 20–30%.
• Store in a climate-controlled environment.
• Use the original charger and avoid fast chargers unless specified.

With proper care, a Noco jump starter can last 5–10 years or more. That’s a small price to pay for peace of mind on the road.

Common Charging Mistakes and How to Avoid Them

Even with the best intentions, it’s easy to make mistakes when charging your Noco jump starter. Let’s look at the most common ones and how to fix them.

Using the Wrong Charger

This is the #1 mistake. Using a charger from another device—like a laptop or power bank—can deliver too much or too little voltage, damaging the battery. Always use the charger that came with your Noco jump starter. If you’ve lost it, buy a replacement directly from Noco or an authorized retailer.

Charging in Extreme Temperatures

Batteries don’t like heat or cold. Charging in temperatures below 32°F (0°C) or above 113°F (45°C) can reduce efficiency and cause long-term damage. If your jump starter has been in a hot car, let it cool down for 30 minutes before charging. Same goes for cold environments—bring it inside and let it warm up.

Leaving It Plugged In Too Long

While modern jump starters have overcharge protection, it’s still best to unplug once fully charged. Leaving it connected for days can stress the battery and reduce its lifespan. Set a timer if you tend to forget.

Ignoring the LED Indicators

Those little lights are there for a reason. If the red light flashes or stays solid, it could mean a poor connection, faulty cable, or battery issue. Don’t ignore it—troubleshoot immediately. Check the cable, power source, and port for debris.

Storing a Dead Battery

Never store your jump starter with a dead battery. Lithium batteries can enter a “deep discharge” state, making them difficult or impossible to recharge. If you know you won’t use it for a while, charge it to 50–70% before storing.

Maintenance Tips for Long-Term Performance

Charging is just one part of the equation. To keep your Noco jump starter in top shape, follow these maintenance tips.

Keep It Clean

Dust and dirt can clog the charging port and vents. Use a dry cloth or compressed air to clean the exterior every few months. Avoid water or cleaning solutions—these can damage the electronics.

Inspect the Cables and Clamps

Check the jumper cables for fraying, cracks, or loose connections. The clamps should open and close smoothly. If they’re stiff or corroded, clean them with a wire brush and apply a light coat of dielectric grease.

Update Firmware (If Applicable)

Some newer Noco models support firmware updates via the Noco app. These updates can improve performance, fix bugs, and add new features. Check the app periodically and install updates when available.

Test It Regularly

Once a month, press the power button to ensure it turns on. If your model has a battery test feature, use it. This helps you catch issues early and ensures the device is ready when you need it.
