Unlike other bulky supplemental power banks, BOLD Knot is a stylish, pocket-sized charger and a power bank for any smartphone. It uses a fashionable, knot-shaped design that’s unrecognizable as a peripheral charger. Tiny battery pack… big power! Get up to 3 hours of extra talk time, 2.5 hours of internet, or 8 hours of music.
