• Cable Quality: Using a damaged or low-quality USB-C or DC cable can reduce charging efficiency. Always use the cable that came with your device or a certified replacement.

Real-World Charging Examples

Let’s say you’re driving home late at night and your car battery dies. You use your NOCO GB40 to jump-start it, which drains about 30% of the battery. You get home, plug it in, and go to bed. By morning, it’s fully charged—ready for the next day’s commute.

Or imagine you’re camping and use your jump starter to power a small fridge overnight. The next day, you plug it into a portable solar panel. Depending on the panel’s output, it might take 6–8 hours to recharge—but that’s still manageable with a little planning.

These scenarios show that while charge time matters, it’s rarely a dealbreaker. With a little foresight, you can keep your NOCO jump starter ready when you need it most.

How to Charge Your NOCO Jump Starter: Step-by-Step Guide

Charging your NOCO jump starter is simple, but doing it right ensures safety and longevity. Here’s how to do it step by step:

Step 1: Check the Battery Level

Before plugging in, check the battery indicator on your device. Most NOCO jump starters have LED lights that show the charge level—green means full, red means low. If it’s already above 50%, you might not need a full charge.

Step 2: Use the Right Charger

Always use the charger that came with your NOCO jump starter. These are specifically designed to deliver the correct voltage and current. If you’ve lost it, make sure to buy a compatible replacement from NOCO or an authorized retailer.

For faster charging, consider upgrading to a NOCO 10-amp or 15-amp fast charger. These can cut charge time by up to 50% compared to standard chargers.

Step 3: Connect the Charger

Plug the charger into a standard wall outlet, then connect the other end to your jump starter. Most models use a USB-C or DC input. Make sure the connection is secure—loose cables can cause slow or interrupted charging.

Step 4: Monitor the Charging Process

Once connected, the LED indicator will show the charging status. Some models have a blinking light during charging, which turns solid when complete. Avoid unplugging too early—interrupting the charge cycle can reduce battery life over time.

Step 5: Store Properly After Charging

Once fully charged, unplug the device and store it in a cool, dry place. Avoid leaving it plugged in for extended periods, as this can stress the battery. NOCO recommends recharging every 3–6 months if the device hasn’t been used.

Pro Tips for Faster Charging

• Charge in a warm room: Cold temperatures slow down chemical reactions in the battery. A warm garage or indoor space helps speed things up.
• Avoid charging in direct sunlight: Heat can damage the battery and reduce lifespan.
• Keep the device clean: Dust or debris on the charging port can interfere with connections.
• Use a surge protector: This protects your jump starter from power spikes during charging.

Charging Your NOCO Jump Starter on the Go: Alternatives and Tips

What if you’re away from home and your jump starter runs low? No problem—there are several ways to recharge it on the go.

Using a Car Charger

Most NOCO jump starters can be charged via a 12V car outlet (cigarette lighter). Simply plug in the included car charger and let it run while you drive. This is perfect for road trips or long commutes. Just keep in mind that car charging is slower than wall charging—expect to add 1–2 hours to your total charge time.

Solar Charging Options

For outdoor enthusiasts, solar charging is a game-changer. NOCO jump starters can be charged using compatible solar panels, though this method is the slowest. A 20-watt solar panel might take 8–12 hours to fully recharge a GB40, depending on sunlight conditions. Still, it’s a reliable backup when you’re off the grid.

Power Banks and Portable Chargers

Some high-capacity power banks can charge NOCO jump starters via USB-C, but this is not recommended for regular use. Power banks aren’t designed to deliver the consistent current needed for fast charging, and they may overheat or fail. Stick to dedicated chargers whenever possible.

Emergency Charging Tips

• If you’re in a pinch, even a partial charge can help. A 30-minute charge might give you enough power for one jump-start.
• Keep a spare charger in your glove box or emergency kit.
• Consider carrying a second jump starter for extended trips—rotate usage to keep both charged.

Maximizing Battery Life and Performance

Charging your NOCO jump starter correctly isn’t just about speed—it’s also about preserving battery health. Lithium-ion batteries degrade over time, but proper care can extend their lifespan significantly.

Avoid Overcharging

Modern NOCO jump starters have built-in protection circuits that prevent overcharging. Once the battery reaches 100%, the device automatically stops drawing power. Still, it’s best to unplug once charging is complete to avoid unnecessary wear.

Store at Partial Charge

If you’re storing your jump starter for months, don’t leave it fully charged or completely drained. NOCO recommends storing it at around 50–60% charge. This reduces stress on the battery and helps it retain capacity over time.

Keep It Cool

Heat is the enemy of battery life. Avoid leaving your jump starter in a hot car or direct sunlight. High temperatures accelerate chemical degradation, leading to shorter battery life and reduced performance.

Regular Maintenance

Even if you don’t use your jump starter often, check it every few months. Turn it on, check the battery level, and recharge if needed. This keeps the battery active and prevents it from entering a deep discharge state, which can be hard to recover from.
