Razer Announces Prio, a Foldable USB-C Mobile Controller

Razer has announced Prio, a compact foldable controller that connects directly to iPhone and Android devices through USB-C. It is a phone accessory rather than a standalone handheld PC: the connected phone provides the screen, processing, network connection, and games.

The controller weighs 101 grams and measures 107 by 67 by 23 millimeters when folded. Razer says its expanding bridge holds phones up to seven inches, giving players full-size physical controls in a design intended to fit in a pocket or small bag.

Direct USB-C without a battery

Prio draws power through its wired USB-C connection, so it does not need charging or Bluetooth pairing. Direct input may also avoid some of the delay and connection management associated with wireless controllers. The tradeoff is that the phone’s port must remain occupied while playing.

Compatibility begins with iOS 18 and Android 14. Razer lists native mobile games, Xbox Cloud Gaming, Steam Link, PlayStation Remote Play, and Razer PC Remote Play among its intended uses. Actual game support can still depend on whether an app recognizes standard controller input.

Capacitive sticks and quieter buttons

The two analog sticks include capacitive sensors that can detect when a thumb is resting on them. Developers may use that information for more responsive input behavior, although support will vary by software. Razer also highlights quiet face buttons intended to make play less disruptive in shared spaces.

A familiar layout provides a directional pad, face buttons, shoulder controls, triggers, and menu inputs around the phone. Because Prio folds inward, its controls are protected during transport instead of remaining exposed at the ends of a telescoping frame.

A controller for games running elsewhere

Prio’s usefulness depends on the phone and the service behind it. A native mobile game runs on the device; Steam Link and remote-play apps transmit a game from a computer or console; cloud services run it in a data center. Connection quality and software support therefore matter as much as the controller hardware.

Razer has not positioned Prio as a replacement for a gaming PC or console. Its appeal is portability: one small wired accessory can add physical controls to hardware many people already carry. Price and regional availability will be important details for buyers, but those were not included in the announcement materials reviewed today.
