SWAP. SPIN. POWER ON.
Replace the battery with a single push and get back to 100% in seconds. Built to charge. Designed to play.
Power shouldn’t be disposable.
In a world where everything is becoming thinner, faster, and more “integrated,” we noticed something no one talks about enough:
When a battery wears out, people don’t just throw away a cell.
They throw away an entire device that still works.
Not because it is broken.
But because it was never designed to last.
From devices to energy
We are shifting from replacing entire devices to upgrading the energy inside them.
Power is no longer tied to a product—it becomes a replaceable core.
One battery. Endless use.
A single battery is no longer the end of a device’s life.
It is a reusable energy unit that keeps the system running again and again.
Energy, redefined
We are redefining energy from a disposable component into a modular system.
Not something you consume once, but something that evolves with use.
