Multiple models of the excellent Backbone Onesmartphone controller are on sale for just $70 (normally $100) during Black Friday. My Best Buy Plus/Total members can get the Backbone for only $65. Keep in mind that you can use either the PlayStation or Xbox editions of the Backbone for Xbox Cloud Gaming and PlayStation Remote Play.
The Backbone One is one of our favorite smartphone controllers, featuring great buttons and analog sticks, a 3.5mm headphone jack, simple setup, and more. Like other split mobile pads, the Backbone slots on either end of your smartphone, turning it into a Nintendo Switch-like handheld that can play Android, iOS, and cloud-streaming games. Best of all, it doesn't need charging, so you can plug it in and start playing anytime. You can even charge your phone while playing thanks to the charging port passthrough.
The Backbone comes in PlayStation and Xbox editions that feature color schemes and button labels that match the console they're based on. The USB-C models work with Android devices and the latest iPhone 15 line. Meanwhile, the Lightning models are compatible with iPhones prior to iPhone 15.
