How to tell if my NOCO Boost GB40 is fully charged?

You can tell if your NOCO Boost GB40 is fully charged by checking the LED indicators on the device. When the jump starter is plugged in, the lights will illuminate in sequence, eventually stabilizing when fully charged. A solid green light indicates a complete charge, while red indicates low battery.

After charging, if you disconnect the unit and the light remains green, it’s a clear sign that your device is ready for use. Always keep an eye on the lights during the charging process to ensure you understand the battery’s status.

For example, if you see the green light flashing, it typically means it’s in the process of charging and not yet complete.

**Pro Tip:** Make it a habit to check the indicator lights before planning to use your jump starter to ensure it’s fully prepared.

**Consideration:** If the lights are not functioning properly or indicators do not change, you may need to troubleshoot the device further.
