Asus’ new USB-C dock supercharges your ROG Ally or Steam Deck

The term “docking station” usually assumes another word, too: “laptop.” Not so with the ROG Bulwark DG300 dock Asus is showing off at Computex 2025: it’s designed for either a phone or the Asus ROG Ally X gaming handheld, with a flirty little support stand for both. The idea seems to be that you can plug in your phone or handheld PC to charge on the dock, than either view it on the stand or use the dock’s output to project the display on to your desktop monitors. The Asus ROG Bulwark DG300 isn’t a USB4, DisplayLink docking station or Thunderbolt dock. It uses a plain 10-Gbit USB-C interface, with DisplayPort 1.4 running on top of it. It’s more of a traditional USB-C hub than anything else. But it’s definitely designed to accompany your gaming rig, with RGB plus some passive cooling for your peripherals. What really sets the Bulwark DG300 dock apart is the flip-up support stand, which looks tailor-made for a phone or especially the ROG Ally handheld. (We’d wonder if it could hold the reported ROG Ally 2 as well, but the demonstration shots Asus ROG sent over do not include a handheld with an Xbox button, one of the keys to the new device.) Asus says it can flip straight up or all the way down, to either angle the phone or just let it recline all the way. It appears that the back of the stand is possibly mesh, to allow air to move in and out and cool the device.

Asus says that you’ll have to use your own charger; Asus recommends its own AC140-01 140-watt USB-C charger. If you do use a third-party charger, it should deliver above 100W, Asus says. Asus says that the dock includes the upstream charging port, plus the downstream ports: a 10Gbps USB-C port, three 10Gbps USB-A ports, a gigabit Ethernet port, an HDMI 2.1 port (3840×2160 at 144Hz or 7680×4320 at 30Hz) and a 3.5mm audio jack.
