OneFlash is a portable battery sharing service that aims to provide convenient access to recharge your smartphone on the go. By locating the nearest OneFlash station and scanning the QR code, users can unlock a portable OneFlash battery to charge their devices. These 5000 mAh batteries can swiftly recharge a phone from 20% to 100% in just one hour and have the capacity to charge up to 3 smartphones simultaneously.

Mobility is a key feature of OneFlash, allowing users to return the battery to any station within the network. This flexibility enables users to pick up a battery at one location, like a café near Bastille, and drop it off at another, such as a gym at République.
