So, you're thinking about using custom keycaps on the ROCCAT Vulcan II Mini Air? Here's what we've found:

This keyboard comes with TITAN II Optical Switches, which are known for their super-fast linear actuation and are a hit among gamers. They could work well with keycaps designed for Cherry MX stems, but you'll want to double-check the specs of the custom keycaps you're considering to be sure they fit.

You can connect the Vulcan II Mini Air via Bluetooth to three devices, which is pretty handy if you switch between a Windows PC, a Mac, and a phone or tablet.

Just keep in mind, if you want to tweak the RGB lighting or key functions, you'll need the ROCCAT Swarm software, and that's only available for Windows. So, while you can use it on Mac or Linux, customizing it fully might be a bit limited.

In short, the Vulcan II Mini Air is a flexible and high-quality keyboard. For custom keycaps, just make sure they fit with Cherry MX stems, and if customization is a big deal for you, using it on Windows offers the most options.

If you're wondering about the noise from the TITAN II Optical Switches on the ROCCAT Vulcan II Mini Air, they're known to give a decent clicky sound. Some folks really love that because it adds to the tactile feedback during gaming.

It's not the quietest keyboard out there, though, so it might not be the best choice for a really silent environment like a shared office or if you're gaming late at night with others around.

The switches are designed to be pretty responsive and fast, which is awesome for gaming, but it can also mean they click a bit more than some other options. So, if noise is a big concern for you, you might want to think about how that'll mesh with your situation.

Overall, if you appreciate that satisfying click and value speed and performance in gaming, then it's a solid option.

But if a quieter keyboard is a must, you might want to consider other options based on what our research and user experiences suggest.

So, you're curious about the battery life of the ROCCAT Vulcan II Mini Air keyboard. Unfortunately, there aren't specific details about its battery life in the manufacturer's info. But here's what we gathered from our research.

The Vulcan II Mini Air is designed to be flexible and convenient, thanks to its cool wireless features. You can connect it via Bluetooth or using ROCCAT's special 2.4GHz Stellar Wireless tech.

In terms of build, it’s got those sweet ROCCAT TITAN II Optical Switches that are known for being speedy and lasting up to 150 million key presses. This could be great if you're a gamer who needs keys that respond quickly. Plus, the Easy-Shift[+] function means you can set more commands on your keys, which adds more flexibility.

Its compact 65% size is a win if you're short on desk space, and there’s some neat RGB lighting for a bit of flair—though some folks think the brightness might not match up to wired models. But it syncs nicely with ROCCAT's AIMO lighting for cool effects.

One thing to keep in mind is that if you want to customize the lighting and set up profiles, you'll need some software.
