-Even though it is marketed as a //"3G travel router"//, the **TL-WR720N** does not include a 3G modem. It simply means that the OEM firmware and GUI support a certain range of USB 3G modems. OpenWRT supports USB 3G modems, too. The router is powered through either a AC source (100-240V, Chinese-style foldable plug, i.e. two prongs without hole), or a mini-USB socket stub (5V).+**__Note:__** TP-Link also markets a very [[http://www.tp-link.com/en/products/details/?model=TL-WR720N|different router under the same name]].
