Will the JuiceBox still charge my car when offline?
An Internet connection is not required for charging. Even if the JuiceBox goes offline, it will continue to charge the car according to your preset schedule. To override the schedule in offline mode, you need to reset the JuiceBox by disconnecting it from power, waiting for 15-20 sec and then reconnecting it to the power source. The unit will then offer an immediate charge when connected to your car.
Furthermore, if you have adjusted the amperage limit via the dashboard or app, the unit will remember that last wire rating (amperage setting) until it is changed again online.
