The Navita phone case has been professionally developed in order to revolutionize the charging game. The Navita case adds another charging port to your phone, to never lose power again. When charging, you can charge both the case and the phone. First, the phone will use its main power source to keep the phone powered. Then, when charge starts to run low, the battery within the case will transfer power from the case to the phone, without you even having to think about it. In the Pulsar app, you can choose a threshold that will decide when the case will start charging your device.
