From Ghost Trappers Wiki
Recharge time is the length of time it takes to recover 1 chrono crystal charge. Recharging only occurs when you are not actively hunting. Recharge time is not affected by friend hunts, auto-hunts, or assisting the live feed. Your base recharge time is determined by which chrono crystal you have activated in your set up.
Cap to recharge time
Your chrono crystal recharge time cannot be reduced below 15 minutes even if you have all of the items that can theoretically reduce the recharge time.
