The Nintendo Switch is a portable home game console in one.
Hence the name: This Nintendo console can "switch" from a home console attached to a television to a handheld game console with controllers on both sides. The Switch Lite cannot be connected to a television and is intended exclusively as a handheld device.
Simply put, the Nintendo Switch is a tablet with a 6.2-inch display and two Wii-style game controllers attached to either end of the device. The Nintendo Switch Lite has a 5.5-inch display, while the OLED model has a 7-inch display.
This setup allows the Nintendo Switch to be a portable game console. But the Switch does much more than just function as a portable console.
