Whether you have a MacBook Air or a MacBook Pro, there’s one port you definitely don’t have: Gigabit Ethernet. But today you can add one for cheap: Amazon’s Woot is selling an official Apple Thunderbolt to Gigabit Ethernet Adapter for just $18, a savings of $11 and the best price we’ve ever seen.
Apple’s Ethernet adapter is simple: It has a USB-C cable on one end and an ethernet port on the other to provide and provides an RJ-45 port that supports 10/100/1000BASE-T networks. It measures just six inches and can easily fit in any bag for travel. To use it, just plug it into an available USB-C port on your MacBook, plug an ethernet cable into it, and select Ethernet in the Network settings.
The sale is good until Wednesday or until stock sells out. And one more bonus—if you’re an Amazon Prime member, you’ll get free shipping.
