The whole point of a portable fan is that it goes where you go. Bedroom in the morning, home office by noon, patio by evening, campsite by the weekend. That flexibility is basically the product’s entire reason for existing. Smart home integration has historically worked against that, though. Most connected fans are smart in exactly one place: wherever the hub lives. The Curtain 3 and the Blind Tilt, products we’ve covered in the SwitchBot lineup, both need the Hub 3 to talk to Apple Home or Google Home. The Hub lives on a shelf. Your fan moves. That tension has been quietly baked into smart home portability for a while.
Matter over Wi-Fi is the fix. It’s the open connectivity standard that Apple, Google, Amazon, and hundreds of other tech companies built together so that devices can join any smart home platform without a proprietary bridge in the middle. The Battery Circulator Fan 2 Pro has it built in, which means it connects straight to Apple Home, Alexa, Google Home, or Home Assistant from wherever it happens to be, bedroom, patio, campsite, corner of the living room you forgot existed. No Hub required. SwitchBot says it’s the first battery-powered air circulator to ship with Matter over Wi-Fi, and and boasts a 70-hour battery, making it last well over a long weekend when you’re out camping. Even more if you hook it to a power bank.
Designer: SwitchBot
A 3,600 mAh battery gives the fan its untethered freedom – that’s enough to run for several days, or even a full week of evenings, without needing a charge. On its highest setting, you get about four hours of peak performance, which is plenty for cooling down a room quickly. SwitchBot also built in a practical safety net for when the battery does run low. The fan supports both AC wall power and USB-C charging, so you can plug it in and keep it running indefinitely. This triple-power setup makes the portability feel genuine, because the fan is never truly out of commission; it just switches from being cordless to corded without missing a beat.
This fan moves a serious amount of air. It’s an air circulator, designed to generate a powerful, focused column of air that can travel up to 33.5 meters, or about 110 feet. With a max airflow of 477 cubic feet per minute (CFM) and a wind speed of 6.5 meters per second, it’s engineered for whole-room ventilation. This is the kind of performance that helps an air conditioner work more efficiently by distributing cold air evenly, or keeps a stuffy room from feeling stagnant. It’s a significant step up from smaller personal fans that are only effective when they are pointed directly at you from a few feet away, making this a much more versatile cooling tool for larger spaces.
At its lowest setting, the fan runs at just 21 decibels. That’s quieter than a whisper, making it an easy addition to a bedroom or a quiet office without creating a distracting hum in the background. This focus on low-noise operation is a critical detail, because a loud fan, no matter how powerful, often gets turned off. The fan also includes a subtle but clever lifestyle feature: an optional aroma diffuser. A small pad near the grille allows you to add a few drops of your favorite essential oil, letting the fan circulate a pleasant scent throughout the room along with the cool air. It’s a small touch that elevates the experience from simple utility to something that enhances the room’s overall atmosphere.
The fan’s physical design is built around its portability. Its clean, sculptural form is available in both black and white, with a large, integrated handle on top that makes it easy to pick up and move with one hand. The unit feels solid without being heavy, striking a good balance for a device meant to be relocated often. SwitchBot also included a thoughtful, practical detail for long-term use: a removable and washable filter. This fine mesh screen sits behind the main grille and is designed to catch larger particles like pet hair and dust before they get into the fan blades. It’s a simple addition that makes maintenance easier and keeps the air it circulates a little cleaner.
That direct Matter connection unlocks some genuinely useful automations. Because the fan can talk to any Matter-compatible platform, you can tie it into routines with devices from other brands. You could pair it with a separate temperature and humidity sensor, for example, and create an automation that kicks the fan on whenever the living room hits 78 degrees. Or, you could include it in a “Good Night” scene that turns off the lights, locks the doors, and starts the fan on its quietest setting. This is where the hub-free design really shines, allowing the fan to act as a truly independent and intelligent part of your home, wherever you decide to place it for the day.
For years, the intelligence in our devices has been tethered to a power outlet and a central hub. By embedding Matter over Wi-Fi in a battery-powered device, SwitchBot has created a gadget that is smart everywhere, not just in one room. It’s a small but significant step toward a more flexible and intuitive connected home, where our devices adapt to our lives instead of forcing us to arrange our lives around them. For $119.99, you get a powerful air circulator, a long-lasting battery, and a glimpse of a more sensible smart home future.
