howtogeek.com:

The Steam Deck is a fantastic gaming handheld, but you don’t have to own one to play your Steam games on the go. All you need is a smartphone, tablet, streaming handheld, Nintendo Switch, PS Vita, or a compatible retro handheld, along with the Steam Link app or the Moonlight and Sunshine combo.
