Why is my Jackery Explorer 240D making noise?

If your Jackery Explorer 240D is making noise, it could be related to the internal fan or the inverter. The fan operates to keep the unit cool during high performance, and occasional noises can be normal. However, persistent loud noises may indicate an issue.

Users often report hearing a low hum or whirring sound while using high-wattage devices, which is typical. For example, if you’re charging multiple items at once, the fan may ramp up to accommodate the heat generated.

PRO TIP: If the noise is bothersome, monitor the unit’s temperature, and ensure it's being used in a ventilated area to minimize the fan's workload.

However, if you hear grinding or rattling noises that are unusual, it may warrant further inspection, as these could be signs of internal damage or loose components.
