This Granite Pro charging cable draws design inspiration from granite, a dense, hard magmatic rock renowned for outstanding acid & alkali resistance and weather durability. We adopt thickened high-toughness nylon braided outer sheath matching granite’s compact solid texture, with reinforced thickened connector joints resistant to frequent bending, abrasion and daily chemical erosion. Stable PD fast charging & data transmission performance, long service life, perfectly suited for daily commuting, travel and outdoor long-term use without easy aging or damage.
