It has a USB-C port, which offers external display support for up to two 4K monitors at 60Hz. The claim is up to eight hours of battery life, though in our experience and testing it's more like two to three depending on the game. Valve says the Steam Deck can charge and play at the same and will come with a 45-watt power supply. Other features include built-in mics, a gyroscope for motion controls, and a '40 watt-hour battery that provides several hours of playtime for most games'. The GPU will apparently have access to up to 8GB of that shared memory. The Steam Deck boasts 16GB of unified LPDDR5 memory, with a total of 88GB/s of bandwidth. You can also expand the storage via microSD on any of the models. There are three different storage tiers available, though: 64GB eMMC storage, 256GB NVMe SSD storage, and 512GB of high-speed NVME SSD storage. In terms of power, every Steam Deck offers the same power 16GB of LPDDR5 RAM and an AMD APU containing a quad-core Zen 2 CPU with eight threads and eight compute units’ worth of AMD RDNA 2 graphics.

It's touch-enabled to let you control suitable games that way, too. Steam Deck features a 7-inch 1280 x 800 touchscreen for 720p gameplay.
