The HP 140W USB-C Laptop Charger (HP part B7NK0AA) is a high-output USB-C power adapter for demanding laptops and mobile workstations. It delivers up to 140 W over USB Power Delivery, enough to charge high-performance HP laptops at full speed, and HP notes it is compatible with most devices that charge over USB-C, both HP and non-HP. HP tests it with its own laptops under its Total Test Process. The adapter body is a slim, flat brick of about 138 x 65.5 x 28.5 mm and weighs about 440 g according to HP's dimension graphic, with an attached USB-C output cable and a detachable AC power cord for easier packing and extended reach. Input is 47 to 63 Hz AC at up to 2.5 A. At least 80% of its plastic is post-consumer recycled material. It is a sensible choice as a replacement or second charger for the office and home, for users whose laptop shipped with a 140 W USB-C adapter, or for anyone who wants one charger for a laptop, tablet and phone. The box contains the adapter, power cord and warranty card; HP covers it with a one-year limited warranty.
