Top 5 Reasons Why Lorantech WinCool Small Is the Best
The Lorantech WinCool Small stands out for delivering 20,000 KRW-level specs at under 10,000 KRW - exceptional value that’s hard to beat.
- 102g ultra-lightweight maximizes portability. At half the weight of a typical smartphone (180-200g), this 102g fan practically disappears in your pocket. The compact 155x65x45mm dimensions make it easy to carry anywhere, and the strap hole at the bottom lets you attach it to your bag with a separate strap.
- BLDC motor delivers quiet operation and longevity. The Brushless DC motor eliminates friction, enabling faster heat dissipation and consistent cool airflow even during extended use. It's quiet enough for libraries, offices, and classrooms.
- 3-blade straight design creates powerful direct airflow. The optimized blade design moves large volumes of air efficiently, with the straight configuration focusing airflow forward without scattering. The manufacturer highlights "powerful direct airflow" as a key selling point.
- Pass-through charging adds practical convenience. Officially confirmed in Coupang Q&A, the fan operates while charging via USB-C. When your battery dies, simply plug it in and continue using it - perfect for urgent situations.
- Complete core features at under 10,000 KRW. You get everything typically found in 20,000 KRW products: 102g lightweight build, BLDC motor, 1200mAh battery, USB-C charging, 3-speed control, and KC certification. The lithium battery also allows airplane carry-on, making it ideal for travel.
