This is a universal 65 W laptop charger that comes with 10 interchangeable DC tips, making it compatible with a wide variety of laptop brands (Dell, HP, Lenovo, Acer, Asus, Samsung, and more). It supports a broad input voltage (100–240 V) for global use, and provides a selectable output voltage (roughly 15–20 V) depending on the tip in use. Safety features like overload, over-current, over-voltage, and short-circuit protection are built in, and its compact design (with a detachable power cable) makes it a flexible solution for both home and travel.
