If this were to happen to a USB storage device, such an event could result in permanent data loss. If the power runs out, any USB device attached to the computer may suddenly disconnect. However, even though the device may function, each additional device attached to the host computer reduces the total available bus power. Many of our devices that include power adapters, especially USB hubs, will function in either self-powered or bus-powered mode. Bus-powered devices can cause issues if they need more power than is available from the host machine. High-current devices usually come with their own power adapter, making them self-powered, in contrast to a bus-powered device that draws all of its power from the host computer's USB interface. While all USB ports provide some amount of power for attached devices, the available power may not be enough for certain high-current devices such as USB hubs or external hard drives. All of our products are backed with a 2-year limited parts and labor warranty as well as Seattle-based email support
