【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.

[About clocks that synchronize time via radio waves] The function of clocks that synchronize time via radio waves only works in the Japanese area. Please be careful. Equipped with a 4cm USB fan, it has more heat dissipation effect than a normal heat sink, making it ideal for preventing thermal runaway. In addition, the USB cooling fan can be adjusted in three stages and rotates quietly. W8 x D4cm small and compact heat sink, can also be used for heat dissipation of various electronic machines. A thermally conductive sheet is also included, so it can be easily attached to the object to be cooled. A single fan guard is attached to the USB cooling fan to prevent foreign objects from interfering with the rotation of the fan. USB 5V
