The Razer Prio is an unusual mobile gaming controller because its biggest selling point is something that most competitors tend to overlook: actually being small enough to carry everywhere. Rather than offering another telescopic controller that effectively turns a smartphone into a larger handheld, Razer has designed the Prio to fold in on itself, creating a remarkably compact package that can disappear into a pocket or small bag. At just 101 grams, it is considerably lighter than many conventional mobile controllers, while still retaining the sticks, D-pad, face buttons, bumpers, triggers and system controls expected from a full gamepad. That makes the Prio an interesting proposition for anyone who wants proper controls for mobile gaming, cloud streaming or remote play without having to plan around carrying a controller. The catch, however, is that almost every decision made to achieve that portability has consequences elsewhere.
The folding mechanism is undoubtedly the most impressive part of the design. When closed, the two halves protect the controls and create something roughly comparable to a thick wallet in terms of its footprint. Getting it open and attached to a phone is not completely intuitive at first, with the locking and rotating sections requiring some familiarisation, but the process becomes considerably easier after a few attempts. Once unfolded, the elastic connection and adjustable rubber inserts allow the Prio to accommodate a wide range of phones and many cases without requiring the usual removal of protective covers. That flexibility is welcome, although the elastic construction does make the whole arrangement feel less rigid than controllers using a conventional sliding mechanism.
The actual controls are considerably better than the tiny dimensions might suggest. The face buttons are tactile, responsive and notably quiet, which is particularly useful when playing in public spaces where constant clicking would quickly become irritating. The D-pad also has a pleasant amount of feedback and works well for many 2D games, although its rolling action can occasionally register an adjacent direction during more precise inputs. The pressure-sensitive triggers are another nice inclusion, giving racing games and other titles requiring analogue input more control than might be expected from something this small. The capacitive thumbsticks are arguably the Prio’s most technically interesting feature, using contactless sensing rather than conventional mechanical components. They respond quickly and should be less susceptible to the kind of mechanical wear associated with traditional sticks, although their extremely small size means that thumbs can sometimes brush against the surrounding plastic. We found them surprisingly accurate even in shooters, while longer tests highlighted the ergonomic compromises that become apparent when using both sticks for extended periods.
That contrast between functionality and ergonomics is ultimately what defines the Prio. There is an impressive amount of controller packed into a very small space, but there is simply not enough room for proper handgrips. The slight rearward angle of the controller helps keep the wrists in a reasonable position, and the phone itself provides some additional support, but the Prio never feels as natural in the hands as a conventional controller. Players with smaller or medium-sized hands may find it surprisingly manageable, particularly during short sessions, whereas larger hands can make the cramped layout much more apparent. The positioning of the D-pad and left analogue stick also makes the controller feel better suited to certain types of games than others. Slower-paced games, platformers, RPGs and retro titles work particularly well, while fast action games requiring frequent simultaneous inputs can become noticeably more awkward.
The Prio is therefore best understood as a controller for short gaming sessions rather than a replacement for a full-sized gamepad. That isn’t necessarily a criticism, because Razer has clearly designed it around the idea of turning a spare ten or twenty minutes into a gaming opportunity. In that role, the 101-gram weight and foldable construction make an enormous amount of sense. There is no battery to charge, no Bluetooth pairing process and, in many cases, no requirement to install software before playing. Connecting the Prio directly through USB-C makes it effectively ready to use, while the dedicated Razer Cortex Mobile button provides a convenient route into a game library for those who want to use Razer’s software ecosystem. The controller can also serve games accessed through cloud gaming and remote-play services, expanding its usefulness beyond native smartphone games.
The wired approach does have one significant drawback, however. Because the Prio occupies the phone’s USB-C port, there is no passthrough charging, meaning the smartphone cannot be charged through the controller while playing. The controller itself never needs charging, which is convenient, but that advantage comes at the expense of the phone’s battery life and charging flexibility. For a quick session this is unlikely to be a major issue, but longer cloud-gaming or remote-play sessions during a long flight can make the omission more noticeable. Compatibility is similarly broad without being completely universal. Android and USB-C iPhones are supported, and most ordinary cases should work, but unusually large camera modules, thicker cases and some foldable-phone configurations can introduce complications. The supplied spacers and rubber inserts help considerably, although getting the right combination can involve some trial and error.
Aesthetically, the Prio is understated and functional rather than particularly distinctive. The black finish fits neatly into Razer’s existing hardware range, but there is little visual flair beyond the familiar branding. That actually works in the controller’s favor to some extent, since this is an accessory intended to disappear into a pocket rather than demand attention in a living room. Build quality is more difficult to assess quite so uniformly, and the elastic folding connection is a potential long-term question mark. The engineering behind making a complete controller fold into such a small package is clever, but the physical compromises required to achieve that size prevent the Prio from feeling as substantial as its price might suggest.
That price is perhaps the biggest obstacle. At around €110 in the European market, the Prio is asking considerably more than its diminutive appearance might initially suggest, and it sits in territory occupied by larger controllers that generally offer better ergonomics. What the buyer is paying for here is not simply a collection of buttons and sticks, but the engineering required to make those controls fold into something genuinely pocketable – which is the core value proposal here. For someone who values portability above almost everything else, that distinction matters. For anyone primarily looking for the most comfortable way to play mobile games for hours at a time, the compromises become harder to justify. The Prio is an impressively focused piece of hardware, but it is also a very specialised one.
The Razer Prio ultimately succeeds because it understands that portability is a feature in its own right – and one that is rare within today’s market. It is light, compact, quiet, requires no charging and offers a surprisingly complete control scheme despite its tiny footprint. The capacitive sticks, analogue triggers and broad Android/iPhone compatibility show that Razer did not simply shrink a controller and call it a day; there is genuine engineering behind the concept. At the same time, the lack of handgrips, cramped controls, absent passthrough charging and questions surrounding the elastic construction prevent it from becoming an all-purpose replacement for a conventional mobile controller. For quick sessions on the train, during a lunch break or while waiting somewhere, the Prio makes considerably more sense than its tiny dimensions might suggest. For lengthy gaming sessions, however, its compactness becomes much more of a compromise. It is an inventive and highly portable controller, but one whose appeal depends heavily on whether convenience and pocketability matter more than comfort.
