Smart Power provides the exact battery status on your Apple and Android device’s screen while charging, so there’s no more guessing. Smart Power precisely indicates remaining power with the APK (Android Application Package File) and App called Powerocks. The power bank’s remaining battery capacity, status, voltage, charging time, remaining time, power evaluation, use frequency, percentage of remaining capacity, temperature, average current, and health index is displayed. Smart Power lets you check your battery’s status everywhere, anytime. It also reminds you to charge your phone by sending you an alert and automatically sets to “do not disturb” during night charging.
