Why is my NOCO Boost GB40 making a clicking noise?

A clicking noise from your NOCO Boost GB40 usually indicates a problem with the connection or insufficient power output. This noise is often the result of the internal relay clicking on and off, which can happen when it is unable to provide power to the vehicle.

First, check the connections between the jump starter and the car’s battery. Ensure that the clamps are securely attached to the battery terminals; otherwise, the device may not establish an adequate connection. Also, verify that the jump starter is charged; if the internal battery is low, it may not provide enough power to crank the engine and will click as it tries.

For instance, if you’re attempting to jump-start a vehicle with a significantly drained battery, the GB40 may struggle to provide enough current, resulting in repeated clicking.

**Pro Tip:** Before using the jump starter, always ensure it’s fully charged to prevent issues.

**Consideration:** If the clicking persists despite proper connections and a full charge, consider that the jump starter may be malfunctioning and needs further inspection.
