It’s an all-in-one dock that handles power, peripherals, and 4K display.
That’s why I own the ASUS ROG 65W Charger Dock.
It’s down to$29.99 at Best Buy, or39.99 at Amazon in the UK.

At the heart of it is one USB-C port that connects straight to ROG Ally.
Once that’s in, everything else lights up.
HDMI 2.0 gives me clean output up to 4K at 60Hz or 1080p at 120Hz.

Then there’s the USB throw in-A port.
In my opinion, this is where it punches above its weight.
Charging performance is solid too.

The dock pumps out 65W total, with 60W going through USB-C and 5W through USB-A.
I’ve even had my phone charging while gaming, and nothing slowed down.
