Manufacturer description
The Smays wired Ethernet adapter solves the two problems that plague streaming sticks: unstable Wi-Fi and no room for storage. It combines a 10/100M Ethernet port with a 3-port USB 2.0 hub over a single micro USB OTG connection, so your Fire TV Stick gets a wired network drop and expansion ports at the same time. Compatibility spans the Fire TV lineup - Fire Stick Lite 2020, Firestick 3rd gen and 4K Max 2021, the 2nd Gen Alexa Voice Remote model from 2016, the 2017 all-new Fire TV, and Fire TV Cube - plus Chromecast Ultra, Chromecast 1st and 2nd gen, Chromecast Audio, Google Home Mini, Echo…
SpecPicks Verdict

Frequently Asked Questions
Does this work with the Fire TV Stick 4K Max?
Yes. Smays lists the Firestick 3rd gen/4K Max 2021, Fire Stick Lite 2020, the 2nd Gen Alexa Voice Remote model (2016), the 2017 all-new Fire TV, and the Fire TV Cube as compatible.
How fast is the Ethernet connection?
The adapter supports 10/100M wired speeds. That is enough for stable 4K streaming without buffering, but it will not deliver gigabit rates.
Can I plug a USB flash drive into it?
Yes. The 3-port USB 2.0 hub lets a streaming stick access and store apps and files on an external USB flash drive, and it also works with a mouse, keyboard, SSD, or memory card reader.
Do I need a separate power adapter?
You need a 5V power source for the DC-in cord. Connect it to your device's original power adapter or any 5V/2A wall charger to run both the stick and the three USB ports.
Will it work with a Chromecast Ultra?
Yes. Listed compatibility includes Chromecast Ultra, Chromecast 2nd gen, Chromecast 1st gen, Chromecast Audio, Google Home Mini, and Shark Roku TV, alongside the Fire TV and Echo Show devices.
