What to do if NOCO Boost GB40 won’t start my car?

If your NOCO Boost GB40 won’t start your car, there could be several reasons for this. First, verify that the jump starter is adequately charged before attempting to start the vehicle. If the jump starter's battery is low, it won't provide enough power to crank your car’s engine.

Next, check the connection of the clamps to both the jump starter and the vehicle’s battery. Ensure they are securely connected to the respective terminals—red to positive and black to negative. If the connections are loose or incorrectly placed, it may prevent the jump starter from distributing power effectively.

For example, if the terminals are corroded or if the battery itself is completely dead, the jump starter may struggle to provide the needed boost. In such cases, you might need to investigate the state of your car battery rather than the jump starter.

**Pro Tip:** Always keep your NOCO Boost GB40 charged and perform regular maintenance checks on your car battery.

**Consideration:** If your car has a more complex electrical issue or a severely drained battery, the jump starter may not be sufficient.
