External power adapter(optional)
- Input: 100-240V~0.3A, MAX 50-60HZ
- Output: +5V - 1.2A
* The hub may be used without the optional power adapter with most USB devices. However, if you want to connect a peripheral that will consume more power, such as a CD-ROM/CD burner, external hard drive or printer, then you might need to use the optional external power adapter to support the extra power requirement of the device.
