Model No.:
JAN:
For charging laptops, it comes with two eUSB cables that support 15V–16V and 18V–20V, along with six eUSB charging connectors, making it compatible with a wide range of laptop brands. It cannot be used with devices that consume 45W or more. (Some models may not be supported. Please check the connector shape and voltage.)
Since it also supports 5V USB power output, it can charge tablets, smartphones (including iPhone 5), mobile phones, handheld game devices, portable music players, digital cameras, and more.
“sofun4jp” is equipped with eUSB, which enables laptop charging while maintaining compatibility with conventional USB port specifications.
eUSB is a technology developed by ROMOSS. Although it looks the same as a standard USB port, using a dedicated eUSB cable allows it to deliver power above 5V. For example, it can output 14V or more, which is required by laptops. In addition, the eUSB port can also be used with a regular USB cable, in which case it automatically operates at 5V. This automatic control function is patented worldwide.
