ASUS Chromebook USB-C charger wattage

ASUS Chromebook, Chromebook Flip, and Chromebook Plus tech specs commonly list a TYPE-C, 45W AC Adapter (published output examples 15 V DC, 3 A, 45 W, or 20 V DC, 2.25 A, 45 W on some CR11 configs). ASUS’s own 45W USB-C Adapter accessory page publishes USB PD 3.0 profiles 5V/3A, 9V/3A, 15V/3A, 20V/2.25A. Match the wattage on your lost cube, then shop a nearby 45W USB-C PD / GaN brick — or 65W when you want PD headroom (ASUS FAQ guidance: a certified charger with output power higher than the recommended power can keep the device working properly). This Chrome OS page is distinct from Windows ASUS USB-C (65W / 100W) and from HP Chromebook USB-C / Lenovo Chromebook USB-C / Acer Chromebook USB-C.

Official ASUS USA / ASUS Global Chromebook tech-spec Power Supply lines and the ASUS 45W USB-C Adapter accessory page publish these wattage classes (accessed 26 Sep 2026). Confirm the number printed on your brick or in your ASUS Chromebook setup guide before you replace it. Full method: how to pick.

Shopping note A 65W USB-C PD GaN can be a spare when your Chromebook brick said 45W — match printed wattage first; do not downsize to a random 18–20W phone cube under load
• Not this page Windows ASUS / Zenbook / Vivobook / ROG USB-C Do not confuse ASUS Windows USB-C tables commonly publish 65W (20V/3.25A PD) and 100W (20V/5A PD) classes — that focus lives on ASUS USB-C charger. ROG high-watt compact plugs that are not USB-C are also not this Chrome OS page. Chromebook ≠ Zenbook/ROG power tables.
