【實用生活app】Doblet|最夯免費app-綠色工廠好玩App

Doblet's building a network of portable batteries throughout your city, to ensure that power is always within reach. Our app notifies you when your battery's running low, and sends you to the nearest Doblet-carrying location.

Buy a one-time charge for $3. Or buy an annual subscription for $30, so you can charge anywhere Doblet is offered, for an entire year. With Doblet, you never have to worry about low battery life again, and you can stop carrying around an external battery.
