At CES 2020 Razer showed off several products, one of which was a mobile gaming controller called Kishi that works with iPhones.
The controllers fit on each side of your iPhone, giving it a similar form factor to the Nintendo Switch. The left controller features a joystick and D-pad, while the right controller has a joystick and buttons. They can connect via the Lightning port or USB-C port in the case of Android phones. They offer pass-through charging ports so you can play and charge at the same time.
