Voidjoy SkyLark S1 Pro Review: A Pocket-Sized Pro Controller

This is the Voidjoy SkyLark S1 Pro, the first controller from JSAUX. Yes, the same JSAUX that makes all those Nintendo Switch 2 docks and accessories I've covered on the channel. This time they're trying something a bit different: take the features of a pro controller and squeeze them into something that fits in your pocket.

Honestly? It's a really interesting controller, and I kind of like it. But it comes with quite a few compromises, and it's definitely not for everyone. Let's go through it.

Disclosure: JSAUX sent me this controller for free. They didn't ask for anything in return, not even a video, and they don't even know this blog exists. All opinions here are my own.

Weight

The first thing I noticed when I picked it up: it's way lighter than I expected. 113 grams. At first that felt a bit weird, but it's a portable controller, and that's the whole point. So, not too bad.

Layout, D-pad and sticks

The layout is Xbox style, with membrane buttons. The D-pad is a standard membrane one, nothing crazy, and it actually works pretty well. I just would have preferred it on top, because that's where my thumb goes for retro games.

The sticks are TMR, the newer magnetic tech, so in theory there's no stick drift. After the Joy-Con years, especially with the original Switch, I really care about that. They feel fine, but the travel is short, very similar to the Switch sticks, which I'm not a big fan of. For the Switch 2 they're fine, but this controller is designed to work with lots of devices, so… yeah.

Triggers

There's a switch that turns the triggers from analog, for racing games, into basically normal digital buttons, for shooters. On a controller this small, that's a really nice feature to have, and it's something you'd expect on a real pro controller.

My one complaint: the controller is pretty thick at the back, so why not put the triggers there? I think they had the room, and it would have felt much more natural. These are basically the same type of shoulder buttons you'd find on the 3DS, but back then you didn't use them in every game like today.

To be honest, I'm not a big fan of this layout. For older titles it's fine, but in newer games my muscle memory is fighting me hard.

ML and MR buttons

There are also two programmable buttons on the front, ML and MR. I rarely use back buttons on other controllers anyway, but these are small, so they're not that easy to hit. And being on the front, you have to press them with your thumb, which kind of defeats the purpose. But you can record macros on them, full button combinations, and that's the real benefit.

The back cover

The back cover looks removable, and JSAUX says it is, but it's not really that easy to take off. It's glued on, and there's nothing inside, just empty space. I know it's there for grip, but on a tiny controller it kind of defeats the purpose. You technically can remove it, but the glue will wear off over time, so it's not something I'd do often.

Connectivity

This is where JSAUX went all in: wired, 2.4G with a dongle, and Bluetooth. Five modes and, I believe, twelve different setups across PC, Switch, mobile and more, and each mode remembers the last device you paired.

They include a dongle in the box, but it has nowhere to go. There's no slot on the controller, nothing. So it's either in your bag, in your pocket, or lost.

You can even turn on a Switch 2 with it. It just took me way too long to figure out how.

The app, rumble and motion controls

There's a mobile app called KeyLinker where you can remap buttons, load game presets, fine-tune the sticks and triggers, and set the rumble intensity. You'll probably want to turn that down, because the rumble is quite loud. Note that KeyLinker is a third-party app, not one made by JSAUX.

There's also motion control, which you can use with the programmable buttons. It's there, it just doesn't work that well. In my testing it was pretty unusable, so I wouldn't rely on it.

Two controllers at once

JSAUX also added a cool feature: you can connect two of them at the same time. Picture this: your kid is stuck on a level and getting frustrated. Instead of grabbing the controller out of their hands, you pick up the second one and help them out. A really cool idea. The catch is that it only works with another Voidjoy, so you need to buy two. I only have one, so I couldn't test it.

Battery

JSAUX claims about 10 hours, and in my testing that's pretty much on par. Charging takes about three hours, which I find a bit much, especially in 2026. It gives you plenty of playtime, but it might be a dealbreaker for some of you.

Ergonomics

This is the big compromise. It's small, so your hands are a bit folded in on themselves. It's fine for quick sessions; for hours on the couch, not really.

But this is a portable pro controller. It won't replace your standard controller, but it's a good option to take on the go. If you like using a pro controller and don't want to carry a full-size one around, this is a good fit for quick sessions. I think there's a market for it.

Price

It's $49.99, and for now it's only sold on the official JSAUX website, not on Amazon or anywhere else. That's cheaper than a lot of pro controllers, but for a portable controller it's a bit on the expensive side. You do get plenty of pro features, but whether that's worth it is up to you. And with Xbox announcing its own portable controller, I'm really curious how the two will compare.

Verdict

So, is it worth the compromise: pro features in a form factor this small, at this price? Will it replace your regular pro controller? Absolutely not. When I'm playing at home for hours, I'm picking up a full-size controller every time.

But on the go, with a Steam Deck, a Switch, or just your phone, it makes a lot of sense. Same for casual gamers, and for kids, because it fits their hands much better.

And for JSAUX's first controller, this is not bad at all. They played it fairly safe, but they added TMR sticks, switchable triggers, two controllers at once, macros and a few other features. Move those triggers, give the dongle a home, and version two could be something special. Maybe improve the build quality as well: I'm not worried it will break, but the plastic does feel a bit cheap at first. Not horrible, and you get used to it.

Will I keep using it? It's definitely going in my travel bag, and it has replaced the 8BitDo SN30 Pro I've used for years. At home, though, I couldn't use it even if I wanted to, because my wife took it. She's exactly the casual gamer I was talking about, she uses it all the time now, and I'm pretty sure I'm not getting it back. So JSAUX, if you're reading this… we need another one.

Would you trade comfort for something that fits in your pocket? Or is a controller only a controller if it's full size? Watch the full video review and let me know in the comments.
