The Yellow Jacket 40847 TitanMax USB-C Charging and Data Cable is for use with the TitanMax Digital Manifold. Use the cable to connect the manifold to a power source. An LED will turn solid green on the manifold when connected. The LED will shut off once the device has reached full charge—approximately 3 to 3.5 hours from a dead battery. To ensure maximum battery life, make sure the TitanMax is charged before and after each job session.
