100W USB-C power adapter for handhelds and laptops

This 2-Power SM100CL-01 adapter delivers up to 100W over USB-C Power Delivery 3.0. It supports output profiles of 20V at 5A, 15V at 3A, 9V at 3A and 5V at 3A. The unit is compatible with devices such as the Asus ROG Ally X, Lenovo Legion Go, MSI Claw, Steam Deck and Nintendo Switch 2.

Practical limits of USB-C Power Delivery 3.0 at 100W

The adapter negotiates the highest voltage the connected device accepts, so a handheld that only requests 15V will draw at that level. Total output is capped at 100W and the input range is AC 100-240V at 50/60Hz. Cable length and quality can affect the power actually delivered to the device.

Installation notes and common issues

Plug the AC cord into a mains socket and connect the USB-C cable to the device; no drivers are required. The most frequent problem is using a cable rated below 5A, which prevents the 20V 5A profile from activating. Ensure the device firmware supports USB-C PD 3.0 for full compatibility.

Questions about this item

Should I pick the 100W model or the 65W version for my Asus ROG Ally X?

The 100W unit delivers up to 100W over USB-C Power Delivery 3.0, so it covers the Ally X and also powers larger laptops like the Zephyrus G16; the 65W variant would limit you to 65W maximum.

What does the 100W rating actually give me when charging a Steam Deck?

The adapter negotiates the Steam Deck's supported profile — typically 45W or lower — so you get the fastest charge the handheld allows without exceeding its own limit.

Does the USB-C port support Power Delivery 3.0 and what voltage steps are available?

Yes, it implements PD 3.0 with fixed outputs of 20V at 5A, 15V at 3A, 9V at 3A and 5V at 3A, covering 100W down to 15W devices.
