Tau 2 3 in 1 Keyring Powerbank

TAU 2 is the emergency power bank for every device (Lightning, Micro USB, USB-C). Its keyring form factor is perfect to let you attach it to your keys when carrying it around. Charge your TAU 2 just by putting away your keys. We even took the time to give you a quick and easy way to set up its charging dock on a desk, on a wall, or even the door side table. Now your power bank is always fully charged and within reach right alongside your keys, eliminating the frustration of a dead battery when you're on the go.<br><br> TAU 2 may not immediately captivate with its 2000mAh capacity, but it's truly impressive. Tested against smartphones from major processor producers, revealing three battery improvement ranges - small-battery phones gained up to 54 percent, mid-battery phones up to 35 percent, and large-battery phones up to 28 percent. Testing results available upon request. <br><br>Designed in Switzerland and Honoree at CES 2023 Innovation Awards.
