Tau 2

A compact power source built for people who demand reliability without bulk. The TAU 2 is an emergency keyring power bank that lives with your keys and solves the classic “forgot to charge” problem with a magnetic wall dock that quietly tops it up every time you get home or to the office.

Design-wise, it’s clean, minimal, and purposeful. The dock hides a USB‑C cable and sticks firmly to a wall or desk, turning into a tidy drop zone for your keys. Integrated cables mean you don’t carry extras, and there’s a clever 4x tap feature to sip power from a laptop if the dock isn’t nearby. With 2000mAh, it delivers a realistic average +30% battery boost, enough to get you through meetings, flights, or late nights without the bulk of a traditional power bank. Digital ID and Lost Mode add thoughtful touches for everyday carry.

This is the kind of accessory that disappears into your routine and shows up when it matters: premium build, simple interface, always charged because it’s always where your keys are.
