Self-service power bank rental systems is a system composed of power bank rental stations, portable chargers, mobile Apps, admin dashboards, and optional Point Of Sale (POS) terminals. Our company places power bank charging stations with portable power banks in public places such as entertainment venues, restaurants, shopping centers, hotels, transportation hubs, to mention but a few. Users can scan the station QR code with their mobile App to rent a power bank and easily return the power bank at any power bank charging station nearby which can be located using their mobile app. If a user’s phone is dead, they can also rent a power bank by inserting a credit or debit card into the POS terminal integrated cabinet. Users can rent and return a power bank at any location with an open port and charge ‘on the go’. After a successful return at any location, users will be charged according to their rental time.
