The Fantech PAC4 is a compact portable mini cooler fan built for everyday comfort in home, office, and desktop workspaces. Designed around a brushless motor, it focuses on efficient cooling with reduced noise and improved durability compared to basic portable fan designs that rely on simpler motor systems. Whether you’re commuting, working at a desk for long hours, or setting up a personal cooling station, PAC4 helps you create a more comfortable temperature zone exactly where you need it.
PAC4 delivers reliable airflow performance with a maximum velocity of 8.9 m/s at 10,000 RPM, helping you feel cooling quickly rather than waiting for gradual temperature changes. Instead of fixed fan speeds, it provides a 120-level stepless infinite scroll speed adjustment mode, so you can fine-tune airflow from a gentle breeze to a stronger jet-like output. This makes it suitable for different environments—quiet office use on lower settings, focused desk comfort during work, and stronger airflow when you need more immediate cooling outdoors or in warmer rooms.
Noise matters when you’re working, studying, or gaming, and PAC4 is designed to keep operation quiet. With noise rated at ≤ 40 dB on low-speed profiling scales, it’s intended to be unobtrusive during everyday tasks. For users who prefer a calmer workspace, the ability to adjust airflow in 120 levels also helps you avoid the “too strong” problem common with fans that only offer a few rigid speed steps.
Powered by a 3600 mAh Li-ion battery, the PAC4 supports approximately 2.5 to 3.5 hours of active runtime depending on your selected speed and usage pattern. An integrated smart LCD digital screen helps you monitor remaining battery capacity and the exact speed layout, reducing uncertainty and making it easier to plan your sessions—especially during travel, power interruptions, or long workdays.
For convenient charging, PAC4 supports USB charging. This makes it practical to recharge using compatible USB power sources, so you can keep the fan ready for daily use without needing specialized chargers. The device is also described as using universal Type-C fast charging lines, aligning well with modern charging setups commonly used for phones and other portable electronics.
Built with a high-impact rugged ABS + polycarbonate premium composite shell framework, the PAC4 is designed to handle regular handling and daily portability. Its grey color and stable flat bottom base make it easy to place on a desk or table as a dependable companion for personal cooling. At a weight of 531 ± 3 g, it’s light enough to carry while still feeling solid for desk use.
Choose the Fantech PAC4 if you want a portable mini cooler fan with brushless motor efficiency, low-noise operation, and precise 120-level airflow control. It’s a good fit for commuters, students, and professionals who spend long hours at a desk and want adjustable comfort without relying on bulky cooling equipment. If you prefer a fan that can be dialed to your exact comfort level—rather than settling for a few fixed speeds—PAC4’s stepless infinite scroll control is especially useful.
The product comes with a 03 Months Warranty, offering additional peace of mind for your purchase.
