Q: Is there any indicator light when the mouse is fully charged?

A: Normally, the mouse needs 3-4 hours for a full charge and it can last for 150 hours after fully charged. The power indicator on the mouse side will turn red while charging, and the red indicator will go off when the mouse is fully charged. ( Warming Tips: To protect thmouse's battery life, we recommend you use a 5V-1A or 5V-2A charger to charge the mouse. Fast charger may damage the mouse. )
