The NexDock is a budget device that adds a 14-inch screen, a Bluetooth keyboard and a capable battery to smartphones, tablets, and PC sticks A California-based startup is seeking crowdfunding via Indiegogo for NexDock, a budget device that increases the productivity of smartphones and tablets by adding a Bluetooth keyboard, a capable battery and a 14-inch screen.
