【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction. 【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary. 【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product. 【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. Ultra-quiet design, as it is a cooling fan that operates continuously, quietness is important. Furthermore, if you are concerned about the quietness, when you switch to low wind mode, the operating noise is at a level that you can't hear at all. A USB cooling fan ideal for cooling various electronic devices such as PS4 Pro, wireless LAN routers, AV amplifiers, computers, and external HDDs. The power cable, which uses USB plug power supply, is divided into two from the center, and two 12cm 5V fans are connected to obtain even more air volume. In addition, the mini fan can be installed freely at multiple angles, increasing the cooling effect. Since the rotation speed can be adjusted in 3 stages, the air volume can be adjusted depending on the usage environment or target. Since the noise value is related to the rotation speed, it operates extremely quietly when set to 2 or 1 mode. Adopts dual ball bearings, which ensure stable rotation of the blades and suppress fan vibration. Furthermore, it has the advantage of a rated life of approximately 60,000 hours, so it can operate continuously 24 hours a day. Light and compact, it does not take up much space and can be installed upright or flat. Metal fan guards are already installed on both sides of the USB fan, making it easier to hold and prevent your fingers from getting into it. It also prevents foreign objects such as cables from entering. basic information: Size: 12*12*3.4cm (including fan guard, for one unit) USB wire length: approx. 100cm Specifications: 5V/0.3A Input voltage: 5V/1A/2A Rotation speed: Max1500RPM Noise: 35dB Weight: Approx. 418g Precautions ①Although the power cord is fixed with resin (*black and red wires), please do not pull the USB cable with too much force. There is a risk of wire breakage. ② Do not force the blades of the USB cooling fan to stop while it is rotating. This may cause motor failure. ③Please note that this is a 5V power supply, so we do not recommend it for people who want particularly strong wind power. ④We do not recommend inserting the USB plug into the USB port of audio equipment.
