Bluetooth and USB-C controllers that either attach to or pair with a mobile device are fairly common; however, the new Razer Prio is described as an "ultra-mobile" gaming controller thanks to its unique foldable design. Built for iPhone and Android smartphones, the Razer Prio is a compact USB-C gaming controller built for portability.
When folded, Razer says the Prio is essentially the "size of a credit card," measuring 107 x 67 x 23mm. Although its 101-gram weight is heavier than your everyday card, it's considerably lighter than most mobile gaming controllers. The Razer Prio is designed for phones with screens up to 7 inches, so it pairs with flagship devices like the iPhone 17 Pro Max and Samsung Galaxy S26 Ultra.
Even though it's compact, it still has all the buttons and functionality you expect from a modern gaming controller. The Razer Prio layout features symmetrical low-profile thumbsticks, a four-way D-pad, ABXY face buttons, bumpers, triggers, and additional buttons for accessing menus and system features. Interestingly, Razer notes this is its first controller to feature "capacitive analog thumbsticks" to reduce drift, making it as much a premium controller as it is a portable, compact one.
The Razer Prio is also designed for ease of use, with a design that supports "most slim to medium phone cases," so you don't have to remove your phone from its case every time you want to use it. As a USB-C controller, it also has no battery and requires no charging.
"With the Razer Prio, we set out to erase the tradeoffs between portability and precision," said Travis Furst, Head of AI Hardware and Console Division at Razer. "It folds down to the size of a credit card, but the moment it opens, it plays like a full controller. That's the whole game, wherever you happen to be sitting."
