Rolling Square TAU 2 02R – 2000mAh Ultra‑Portable Keyring Power Bank (Gray)

The TAU 2 02R (Gray) is Rolling Square’s second‑generation mini power bank, engineered for maximum portability and universal compatibility. It’s smaller than an AirPods Pro case and attaches directly to your keyring, ensuring you always have emergency power at hand.

Unlike traditional power banks, TAU 2 integrates dual connectors hidden inside a hook mechanism (Lightning + Micro‑USB), plus a USB‑C port that works as both input and output. This makes it compatible with virtually all smartphones and accessories.

The magnetic dock allows you to recharge TAU 2 easily at home—just slide it onto the dock and it charges automatically.
