The PlayStation Portal is purely a Remote Play streaming device, so it doesn't play games locally via cartridges, discs, or built-in storage like the Switch or Steam Deck. This means that it relies on an internet connection and a PS5 console in order to work, and your experience will depend on how strong your Wi-Fi is. However, if you have a stable connection, the Portal delivers seamless gameplay that can make it feel as if you're sitting on your coach in front of your console even if you're miles from your PS5.
