Razer has introduced the Prio, a foldable smartphone controller that measures about 101 x 67 mm when folded and weighs just 101 grams. When unfolded, it transforms into a full-sized controller on both sides of a smartphone, connecting via USB-C and drawing power directly from the phone. The Prio is compatible with smartphones up to 7 inches in size, including high-end models like the iPhone 17 Pro Max and Samsung Galaxy S26 Ultra. Most phone cases remain in place when the controller is attached, making it convenient for users who want a hands-free gaming experience. Priced at 109.99 euros, the Prio is now available for purchase on Razer’s official website and Amazon. The controller features a four-direction tactile directional cross, two bumpers, two triggers, and four silent front buttons with tactile feedback, allowing for precise and responsive gameplay. A dedicated button on the Prio opens Razer Cortex Mobile, a free app that functions as a centralized library for gaming content. While the app itself is free, some of the services it references require payment. The Prio is compatible with major cloud gaming and remote play platforms, such as Xbox Cloud Gaming, PS Remote Play, Steam Link, and Razer PC Remote Play. It can also connect to a PC running Windows 11 via USB-C, similar to other gaming controllers designed for desktop use. One of the key selling points of the Prio is its anti-drift capacitive sensors on the directional sticks. These sensors are designed to prevent unintended movement of on-screen characters, which can be a common issue with cheaper or lower-quality controllers. This feature aims to provide a smoother and more accurate gaming experience, especially for mobile and cloud gaming enthusiasts. The Prio is positioned as a direct competitor to the Backbone One, a well-known controller in the same price range that has been on the market for some time. Compared to Razer’s own Kishi V3 models, the Prio is much lighter—101 grams versus 175 grams for the Kishi V3 and 268 grams for the Kishi V3 Pro. However, it lacks a pass-through charging port and clickable sticks, features that are available on the Kishi V3 models. While the Prio offers a more compact and lightweight design, users who require additional features like pass-through charging or clickable sticks may still prefer the Kishi V3 models for their enhanced functionality.
