--------------------------------------------------- 【Voltage Compatibility】 Our products are selected to support international voltage ranges (e.g. 100–240V). However, please make sure your local voltage is compatible before use, as incorrect voltage may still cause 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 appropriate voltage or equipment. --------------------------------------------------- This is a USB hub that can be powered by both self-powering and bus-powering devices and comes with an AC adapter. It supports USB 3.0, achieving a transfer speed of 5Gbps, which is approximately 10 times faster than conventional USB 2.0 (theoretical value). If your computer or device supports USB 3.0, you can transfer large amounts of data at high speed. It can be used with USB 2.0/1.1, so it can be connected directly to computers and devices that support USB 2.0/1.1. By connecting the included AC adapter and using it in self-powered mode, a stable power supply is possible even when using power-hungry devices such as hard disk drives and DVD drives (*).
