Razer Prio Folds a Full Phone Controller Down to Credit-Card Size

Most phone controllers are portable only in the technical sense. They fit in a bag, but fixed grips and exposed thumbsticks make them awkward to carry in a pocket. The Razer Prio tackles that problem with a controller that folds to 107 × 67 × 23 millimeters and weighs 101 grams.

Twist it open, connect a USB-C phone, and the compact block becomes a complete gamepad. The Prio costs $99.99 in the United States, so this is not a budget accessory. Razer is charging for a design that can stay with your phone instead of being left at home.

The folding mechanism is the main feature

When closed, the Prio has roughly the footprint of a credit card. That description needs context: at 23 millimeters, or just under an inch, it is much thicker than anything that belongs in a wallet. It is still small enough for a jacket pocket, a loose trouser pocket, or the corner of a small bag.

Opened around a phone, it provides two analog sticks, a four-way directional pad, face buttons, bumpers, and triggers. Razer uses low-profile capacitive analog sticks rather than conventional contact-based parts. The company says the contactless sensing is designed to reduce wear and stick drift. That is a durability claim, not proof that drift is impossible.

The face buttons are also designed to be quiet, which makes sense for the places this controller is meant to be used: buses, waiting rooms, airports, and short breaks around other people. A dedicated Cortex Mobile button opens Razer’s game library app without searching through the phone first.

USB-C removes two everyday annoyances

The Prio draws power through its direct USB-C connection. There is no Bluetooth pairing process and no separate controller battery to remember to charge. A wired link also avoids the extra wireless step between a button press and the phone.

Razer rates the holder for phones with displays up to 7 inches, including large models such as the iPhone 17 Pro Max and Samsung Galaxy S26 Ultra. Most slim and medium-size cases should fit, although a bulky protective case may still need to come off.

Compatibility starts at iOS 18 on iPhone and Android 14 on Android phones. That leaves older Lightning-equipped iPhones outside the target market, and an older Android handset may need an operating-system update before it qualifies.

It can reach games beyond the phone

The controller works with supported local mobile games, but streaming and remote play make the hardware more interesting. Razer lists Xbox Cloud Gaming, Steam Link, PS Remote Play, and Razer PC Remote Play. That covers cloud titles as well as games running on a PC or PlayStation elsewhere.

The controller does not include those services. A compatible game, console, computer, subscription, and reliable network may still be required. The Prio supplies physical controls; it cannot fix a weak connection or add controller support to a game that was built only for touch input.

The $100 decision comes down to where you play

A full button layout does not automatically provide the same hand comfort as a full-size console controller. The grips and sticks have to collapse into that small folded shape, so long sessions may favor a larger telescoping model. The 7-inch limit and USB-C requirement narrow the device list as well.

For someone who usually plays at home, pocket size may not justify a $99.99 purchase. For a commuter or frequent traveler who already streams PC, Xbox, or PlayStation games to a phone, the calculation is different. A controller that is actually present when there are 20 minutes to play is more useful than a roomier one sitting in a desk drawer.
