Amazon's $59.99 TV stick needs no wall plug

Amazon launched a $59.99 Fire TV Stick 4K, a plug-in device for watching shows in extra-sharp 4K. It draws power from the TV's USB socket, so no wall plug is needed. It uses Amazon's updated TV menu software and faster Wi-Fi 6, plus Bluetooth 5.3 and low-energy Bluetooth for remotes and headphones. It replaces the Select and Plus 4K models.
