On sale for Prime Day is the Smays Ethernet Adapter w/ built-in USB OTG Hub for $10.39. While this isn’t a particularly spectacular deal, I know a lot of you just picked up new Fire TV Sticks and Fire TV Cubes during Prime Day and this is easily the best accessory to get for your new or existing Fire TVs. This simple adapter adds a 100 Mbps Ethernet port and 3 full-sized USB-A ports to your Fire TV. It comes with a separate power cable so that it can power a Fire TV Stick while it’s being used. The Ethernet portion is great for a more stable network connection if you have a nearby router. The USB port allows you to expand your device’s internal storage, either for additional apps or for accessing external media, and lets you connect USB peripherals like mice, keyboards, gamepads, and more. The adapter is compatible with all Fire TV Stick models (Standard, Lite, 4K, and 4K Max) except for the original 1st-gen Fire TV Stick from 2014. It’s also compatible with all Fire TV Cube models and the 3rd-gen Fire TV pendant. That said, read this article to understand how external data access differs among Fire TV model, especially if you have a Fire TV Stick 4K. Amazon’s own Fire TV Ethernet adapter is fine, but its biggest flaw is that it doesn’t also pass data through its micro USB connection, so you can use it if you also want to connect something else to the Fire TV. This Smays adapter solves that in a single compact device and that’s why it’s my go-to recommendation for Fire TV Ethernet adapters.
