Featuring a simple yet flexible design, the Plugable 10 Port USB 2.0 Hub provides easy expansion for any USB capable system. All upstream and downstream ports are on the front and back sides of the hub, with two rear ports minimizing desktop cable clutter. Two BC 1.2 Standard complaint ports swivel to a vertical position to allow easy insertion with one hand. Blue LED bar reports power status. Hub Controller Cascaded Terminus Technology hub chips support efficient data transfers for maximum performance across all devices with minimal power draw. Supports Multiple Transaction Translators for optimum performance when a combination of USB 2.0 and 1.1 devices are attached. Low power consumption is achieved with 0.18um technology and declocking/depowering of unused ports and parts of chip not currently in use. USB Charging Battery 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.
