Original ASUS 45W USB-C Charger ADP-45EW B – Type-C AC Adapter for ZenBook 3 and Chromebook Flip

The ASUS ADP-45EW B is a 45W USB-C AC power adapter for compatible ASUS laptops and other ASUS devices that support USB-C charging. It has a number of output profiles (20V @ 2.25A, 12V @ 2A and 5V @ 2A), a universal 100-240V AC input and 50-60Hz frequency.

The ASUS 45W USB-C charger is marketed as being compatible with a range of ASUS ZenBook 3 models, Chromebook Flip devices and other USB-C powered devices. It can be used as a replacement power adapter provided the original adapter in question has a compatible USB-C input and meets the required charging requirements.

Before you go and buy it, make sure you check the part number, the supported USB-C charging profiles and the power requirements of your device. A USB-C connector on its own doesn't necessarily mean it'll work.
