The HP 65W GaN USB-C LC Power Adapter (D36ZXAA) is a compact laptop charger that uses gallium nitride (GaN) technology to deliver more power with less heat in a smaller body than conventional adapters. It supplies up to 65 W through USB-C Power Delivery 3.0, so it can charge most USB-C notebooks, tablets and phones, not only HP devices, and supports HP Fast Charge on compatible HP notebooks. That makes it a useful spare for a second desk, a travel bag or a mixed fleet of USB-C laptops. The brick has an attached USB-C output cable and a separate AC power cord, both included along with a warranty card. It measures about 91 x 53 x 31.5 mm and weighs 250 g. Operating range is 0 to 35 degrees C and 20 to 95% relative humidity. The housing contains at least 25% post-consumer recycled plastic and the packaging is FSC certified. Check that the laptop you want to charge supports USB-C charging and draws no more than 65 W; high-performance workstations may need a larger adapter.
