Performance
Our 5000 mAh portable batteries can charge your phone from 20% to 100% in just one hour and can charge up to 3 smartphones.
Mobility
Return the OneFlash battery to any station in our network. Grab a battery in a café near Bastille metro and drop it off at a gym in République.
Sharing
Each OneFlash battery is equipped with 3 cables compatible with all smartphones. Charge up to 3 phones at once and share energy with your friends!
Ecology
OneFlash aims to reduce lithium overconsumption by offering a network of 100% recyclable rental portable batteries. We promote a sharing economy to reduce the purchase of personal external batteries.
Proximity
To make our rental and sharing system work for you, we've brought OneFlash to your favorite places, including shopping malls, gyms, airports, train stations, libraries, museums, and many more! Let us know where you'd like to see OneFlash stations!
Accessibility
We've made renting portable batteries convenient. That's why OneFlash is mostly free! To ensure availability for everyone, a €19 deposit is held but not charged. Plus, you have up to 4 days to return it.
Additional Functionality
At OneFlash, we think of everything. That's why we've added a micro USB port on each of our portable batteries. So, within the deposit period, you have the option to recharge the battery yourself. This gives you more flexibility and allows you to use the battery for as long as you need.
Practical, right?
What's New?
We're always planning new features and regularly updating the app to provide you with the best OneFlash experience possible!
