ASUS's portable gaming handheld packs 10Gbps USB-C with DisplayPort 1.4 Alt Mode, plus a proprietary ROG XG Mobile interface for external GPU expansion. Charging at 65W via USB-C means you'll sacrifice display output while powering up—a dock that splits video separately is essential. The UHS-II microSD slot is faster than Steam Deck, and the 3.5mm jack handles audio without fighting for bandwidth. Here's every port and the cables you'll need.
ASUS ROG Ally gaming handheld featuring combo USB-C 3.2 Gen 2 and proprietary ROG XG Mobile interface port with DisplayPort 1.4 Alt Mode, microSD card reader with UHS-II support, and 3.5mm audio jack.

Notes & Compatibility
Single multi-purpose port combines USB-C and proprietary ROG XG Mobile interface for external GPU support. MicroSD has faster UHS-II speeds than Steam Deck. 65W USB-C Power Delivery charging. XG Mobile port limits third-party eGPU options. Because it is one physical combo port, an XG Mobile enclosure occupies the only USB-C you have — you cannot run the eGPU and a separate USB-C dock at the same time. Worth knowing before you buy a card: Asus has acknowledged that under thermal stress the microSD reader can malfunction, addressed with a firmware update to the default and minimum fan speeds and an RMA programme. A card that disappears mid-session is a known fault of this unit, not the card or the reader cable.
