The Duckiebattery is a custom-designed smart power bank for robotics applications.

It is special because it can communicate to the connected computer (e.g., Raspberry Pi, Jetson Nano, etc.) via USB, enabling a number of autonomous behaviors.

Moreover, it is designed to provide continuous output in all operating conditions: in charge (for development), not in charge (for autonomous operations), when plugged in, when plugged out. Most power banks on the market will drop output voltage for a few milliseconds when plugged in/out, causing the robot to reset. 


  • Dimensions:  62 x 100 x 24.5 mm

  • Weight: 189g (fully charged) 

  • Capacity: 10 Ah at 3.7V (37Wh)

  • Charging: Micro USB 5V at up to 2A 

  • Outputs: 2x USB type A 5V at up to 4A combined
