If your phone runs low, rent an external battery.
How does it work?
Before your phone runs out of battery, download the app from the App Store, Google Play, AppGallery or RuStore
— find the nearest EnerGO terminal. In the Gallery, they are located on the 1st floor near the cloakroom and on the 4th floor in the food court area (next to Subway and opposite Sushi Booffet)
— in the application, enter the terminal number or scan the QR code on it,
— take a power bank with the necessary wires,
— after use, return the battery at any point from the app.
