Of the many new devices that Razer was showcasing at their CES 2020 suite, I was instantly drawn to the Razer Kishi, their successor of sorts to the Razer Junglecat. Their design shift from a pair of wireless controllers to an all-in-one unit that you can slide your phone wasn't anything new. After all, we had seen this before from Gamevice, which isn't too surprising, given the Gamevice branding and partnership that Razer is putting into the Razer Kishi.

While the Razer Junglecat uses a wireless Bluetooth connection to pair the controllers to the phone, the Kishi operates via the same way that the Gamevice does: via your phone's USB-C connection. Connection is done simply by taking your phone out of its existing case (so if you drop the Kishi mid-game, you're SoL) and into the USB-C connection in the right handset and stretching the docking station outwards until you can slip your phone into the left side (and yes, there is a Lightning-supported version for iOS devices). Once it's in, your phone is instantly transformed into a powerful Android competitor for the Nintendo Switch. At the bottom of the right hand grip is a passthrough for whatever charger your phone needs, handy if you plan on an all gaming session.
