About USB Powered Ethernet Hubs
USB ports have the capacity to provide a substantial amount of power to connected devices, often eliminating the need for an AC power adapter. A USB powered Ethernet hub runs on power from the USB rather than power from an AC adapter connected to a wall outlet, making it possible to set up a small Ethernet network with only battery power available.
This means that laptop computers equipped with a USB port can power a small wired Ethernet network without the need for AC power.
Shoppers looking for a USB powered Ethernet hub should consider the options listed below as they begin their search.
While shopping, keep in mind the fact that these hubs draw their power from the computer's USB port, but do not interface with the computer through the USB. This means that users wishing to include the host computer in the network must bring an Ethernet cable to connect the computer's Ethernet jack to an Ethernet port on the hub.
