I bought a new Firestick 4K max International and recieved it yesterday.
It is small with a cable that either connects to mains or USB for power. Mine is connected to USB, but some TV's may not be compatible, so also carry a plug that a USB connector can connect to.
I use Tivimate as my IPTV player and set it up using a fake MAC, so you should be able to use it anywhere. I also installed my VPN and multiple Apks to watch free Movies and Series. So far I can do everything on it that I could do on an Android device
