PRSRV (pronounced preserve) is an innovative, energy efficient power bank designed to preserve and extend the average device’s battery life. PRSRV is the first power bank that can be used in two different locations simultaneously as it includes a charging station as well as a removable battery which functions as a charger on the run. This credit card sized battery is designed to fit discretely in a wallet to provide consumers a portable, wire-free, sleek power bank. PRSRV’s economic design protects mobile’s battery life and prevents overcharging by automatically cutting off electricity to the mobile once it is fully powered. Surplus power is then directed to charge the back up power bank, reducing energy consumption and efficiently charging first your mobile and then PRSRV. PRSRV’s unique, patent pending design is compatible with both Apple and Android devices.
