The Challenge

The Problem

Access

Millions run out of battery daily with no convenient charging option when away from home or work.

🌎

Environment

Personal power banks rarely get recycled, end up in landfill, and are manufactured with no regard for carbon footprint or material sourcing.

🔗

The Gap

No existing solution combines convenient on-demand charging with genuine sustainability commitments and transparent impact tracking.

Our Answer

The Solution

Circul8 is a shared network of smart power bank stations across the city. Rent a fully charged power bank in seconds, return it at any station.

  • 3-in-1 charging: Lightning, USB-C, and Micro USB in every unit
  • 15,000mAh capacity: charge your phone up to 4 times per rental
  • QR scan to unlock: get a power bank in under 10 seconds
  • Return anywhere: drop off at any Circul8 station in the network
