The TAU 2 Powerbank from Rolling Square is a small, compact 3-in-1 charging option that is a convenient alternative to other heavy chargers. With a battery capacity of 2000 mAh, it provides a reliable power source for travelling and also supports pass-through charging.Â
Thanks to the two integrated cables, the TAU 2 is compatible with any smartphone and portable device and can be conveniently attached and detached from the key ring. The dual cable combines lightning and micro USB in one and is therefore suitable for all Apple and micro USB devices. The second separate USB-C cable supports the latest devices as well as Android devices or consoles. The power bank can be conveniently attached to the key ring and quickly attached or removed again thanks to the integrated removable key ring cover. When the cover is removed, the two ready-to-use cables are visible and can be used immediately.
The slim power bank can be positioned in various places in the home using the magnetic charging station and removable rubber adhesive surface supplied. This means the power bank is always to hand and can be charged quickly.Â
For additional security and functionality, the Rolling Square power bank has an integrated NFC tag and optional stick-on QR code stickers that enable digital ID and lost mode.
