U:NIT

What it does

U:NIT is a modular powerstation made with repurposed e-bike cells. The metal casing is built for tough outdoor use. Each POWERUNIT works as a powerbank and can be replaced, making the system reliable, repairable and ready for shared moments.

Your inspiration

U:NIT started with a simple question. One of our team members, who worked as a bike mechanic, kept wondering, "Are these batteries really fully broken?" He saw how e-bike batteries were thrown away every day, often because of just one faulty part or a few bad cells. That question sparked our project. We wanted to prove that there is real value left in these cells. Together, we explored how to turn waste into a product that actually works and tells a story.

How it works

U:NIT is the main powerstation that holds 10 POWERUNITS, which function as removable powerbanks. To access them, the side panel opens like a door by loosening the G-Hook straps. Once opened, the POWERUNITS can be removed and used individually for mobile charging. They slide in and out smoothly and connect automatically. Each POWERUNIT can be returned for cell replacement, allowing the electronics and casing to be reused. The carry strap doubles as a handle and attachment point. A digital display shows the overall system status and is operated with a single button. U:NIT includes four USB-C outputs, two USB-A outputs, a 12V car socket, an XT60 input for solar charging, and a 5.5 mm input for standard charging. This modular setup allows for flexible use, easy repair and long-term service.

Design process

After identifying the waste problem in discarded e-bike batteries, we began by analysing how to safely reuse individual cells. We tested capacity, discharge curves and impact resistance to select only the best-performing ones. We conducted a market benchmark and looked for the real gap. We used various design methods to shape a bold, honest brand identity as a consistent foundation. We explored different handle concepts, exoskeleton frames and color directions. Dozens of prototypes helped us refine the click-in mechanism, the G-Hook strap system and the casing strength, while keeping things simple and intuitive. Impact tests and hands-on iterations led to a product that prioritises repairability, ease of use and long-term durability. We also explored sourcing materials sustainably, such as using old traffic signs for the metal casing and recycled 3D filament for the POWERUNITS. While some refinements are still needed for production, U:NIT is ready to take its next step from prototype to real-world impact.

How it is different

Most powerstations are made of plastic and become e-waste once the battery capacity drops. They target outdoor users who often value sustainability, yet their products can’t be repaired or upgraded. U:NIT is different. It’s not just another eco-product. It is a fully circular design with a business model to match. POWERUNITS can be returned, refilled and reused, reducing waste and extending lifespan. We didn’t try to beat major brands on price or specs. Instead, we built a story. U:NIT sells a feeling, a sense of connection to people, moments and nature. We designed for repairability and durability, but also focused on how it looks, feels and lives in real moments. Around a campfire, at a BBQ or on the road, U:NIT powers your moments together.

Future plans

We have built the first fully functional model and are testing it in real outdoor situations. Based on these insights, we will optimise both the POWERUNITS and the U:NIT powerstation. We are also working with local manufacturers and an engineer to simplify the electronics. First, we will build hype through social media and then reveal a launch date to create momentum for our Kickstarter campaign. If there is enough interest, we aim to bring U:NIT to market as a full brand.
