100W USB-C charger for Asus laptops

This 100W USB-C power adapter supplies up to 20V at 5A and also delivers 15V, 9V and 5V profiles for lower-wattage Asus models. It is built for owners of ROG Ally, ROG Flow, Zephyrus, Strix, ZenBook and Vivobook S devices that charge through a USB-C port. The unit weighs .55 pounds and uses a two-pin mains plug.

USB-C Power Delivery limits

The adapter negotiates power over USB-C Power Delivery up to 100W; it cannot exceed the 20V 5A ceiling defined by the standard. Cables must be rated for 5A to carry the full 100W — thinner cables will restrict output to 60W or less. The brick accepts 100-240V AC input at 50 or 60Hz for worldwide use.

Check your laptop before ordering

Verify that your Asus laptop charges via USB-C and that its original adapter is rated at 100W or below; this unit will not suit machines that require a proprietary barrel connector or more than 100W. Confirm the USB-C port on the laptop supports Power Delivery charging, because some Asus models use the port for data only.

Questions about this item

Should I pick the 100 W or 65 W option for my ROG Ally?

The adapter negotiates 20 V at 5 A for 100 W, then steps down to 15 V 3 A, 9 V 3 A or 5 V 3 A, so one unit covers every listed profile.

What does the 100 W rating deliver to a Zephyrus G16?

At 20 V and 5 A the brick supplies the full 100 W the G16 can draw, while the 2.25 A rail handles lower-power states.

Which USB-C power standard limits the output in practice?

The charger implements USB Power Delivery with fixed 20 V 5 A, 15 V 3 A, 9 V 3 A and 5 V 3 A rails, capping at 100 W.
