TAU2 - The smallest universal power bank, 50% more powerful
TAU2 is the smallest keychain 3in1 power bank in the world with integrated cables (Lightning, MicroUSB and USB-C). It's 50% more powerful than TAU, but, counterintuitively, even more compact.
It's an emergency power bank that can provide a boost of up to 70% of power to a smartphone, and it's smaller than AirPods.
TAU2 comes with a dock that can be fixed on a counter, a wall or a desk. Everyday, when we get back home, we set down our keys somewhere. We exploit that daily habit to recharge TAU2, so it's always charged, without having to think about it.
