The hub has data transfer rates up to 5Gbps allowing data to move quickly between devices. The hub’s one upstream port and seven downstream ports provide USB 3.0 SuperSpeed transfer rates when linking a USB 3.0 host with USB 3.0 devices. USB’s practical speeds vary by device and usually are lower than the theoretical maximum speed.
The hub comes with a premium twelve-volt, 2.5 amp AC power adapter for powering up to USB 3.0’s maximum of 900 milliamps per port for today’s power heavy devices. The power adapter included provides a total of 5 feet of distance between the hub and the electrical outlet. Power management features USB over-current detection and protection.

USB3-HUB4AC1 units have been tested to work well with both Windows 8.1, and OS X 10.9.x, as well as older systems running Windows 8, Windows 7, Windows Vista, Windows XP, and OS X systems with both USB 3.0 and USB 2.0. Older USB 1.1 devices connected to USB 2.0 systems via the hub are also supported.
For desktop PCs where USB 3.0 ports may be hard to reach, the HUB4AC1’s design with top-facing angled ports can make connecting devices easier. The extra ports on a USB hub can also help avoid damaging built-in ports when frequently swapping devices. The built-in power button on the hub also makes for a convenient way to quickly disable all attached devices with the press of a single button, to make sure attached USB devices are off and saving power.
USB ChargingBattery charging over USB has become a standard practice but the actual charging behavior of different devices is often unpredictable and sometimes disappointing. The devices themselves decide how much current to draw and manufacturers haven’t settled on a single standard. We constantly test our products with as many different devices as possible and publish the results so it’s easy to determine the charging behavior to expect from your device on each of our USB products. These are the results for the devices we’ve tested on this charger so far.
For hubs, "Hosted" means the hub is attached to a host computer that is powered on. "Unhosted" means just the opposite, that the hub isn't attached to a host computer, or that the host computer is turned off. This doesn't apply to stand-alone chargers that only plug in to a wall outlet.
The "Estimated Charging Time" column is the minimum amount of time that the device would take to charge if it was fully drained. This is just an estimate! We provided this to give a general idea of the expected charge time. If this column is blank for a device, that means that the device indicated that it wasn't charging. In this case, even if the device is drawing power, it will likely either "tread water" keeping the battery at a constant level, or slowly lose ground.
How do I update the firmware on my hub?
Firmware updates should not be necessary for any of the USB3-HUB4AC1 units sold to date.

There is a blue led for each of the USB input ports on the hub. The LEDs turn on when a USB device is connected and recognized by the operating system. The LED by the charging port is to indicate power on the hub.
Is this hub a good match for my Raspberry Pi?
Because the Raspberry Pi is a USB 2.0 device and can’t take advantage of USB 3.0 functionality as well as mixed results from users, we do not recommend this hub for use the Raspberry Pi. The hub we do recommend is our 7 port USB 2.0 hub
