"Micro Cooling Fan" using contact-type charger, fan base is fixed to the battery charger on the realization of charge, and convenient. An exception fan built battery can work 20 hours continuously at a low gear, summer heat resistance is no pressure. The innovation also lies in changing the fan blades of the fan, dual-angle blades make a greater range of air diffuser; "Micro Cooling Fan" swing angle can also be adjusted, compared to the traditional fixed head 150 ° swing, You can set the swing range, simply rotate the head, respectively, when the fan is screwed to the start position and end position, after swinging in between these two positions. "Micro Cooling Fan" is also equipped with a remote control, you can adjust the swing angle and speed of the blades, even at maximum speed and no noise, so you can rest in a quiet environment. Due to the use of green energy-saving technologies, the impact on the environment of ultra-low power 1.5W small.
