What to Compare Before Buying
- Battery life: The stated runtime reaches up to 24 hours on low or 10 hours on high. Compare that with how long you want the fan to run between charges.
- Size and weight: At 17.8 cm wide, 21.3 cm high and about 400 g, it is worth checking against the desk, bag or shelf space you have available.
- Speed control: The fan has 4 speeds, so compare whether that range is enough for the airflow level you want.
- Charging setup: USB-C 5V/2A is part of the specification, so confirm that suits your charging plans.
- Cleaning access: The detachable front cover makes routine cleaning simpler, which matters if you want easier maintenance.
Using It in Practice
The foldable stand lets the fan angle its airflow on a desk, bedside table or similar surface, while the LED display helps you keep track of battery level and speed. If you plan to use it away from mains power, the battery percentage readout is a practical detail for planning recharging rather than guessing.
Before You Decide
Check the battery life, dimensions and charging method against the space and run time you need. Confirm that 4 speed settings are enough for your preferred airflow, and make sure the foldable stand and detachable front cover suit how you want to use and clean the fan.
