Use what already works
If your own power bank is charged, use it. If a convenient outlet and the right cable are available, use those. Shared power is not meant to replace a solution that already works for you.
The unplanned moment
The useful moment is when you forgot the charger, your own power bank ran flat, the connector does not fit, every convenient outlet is occupied or you cannot leave your phone beside a wall.
Power that moves with you
A portable power bank lets you keep the phone in your hand for messages, maps, mobile payment, rides and the next part of your day. The supported journey is simple: scan, rent, charge and return.
