mobile split gamepad

smartphones and tablets usually only have a usb c port 

on the lower side of the device 

so that it becomes problematic to connect a split gamepad 

on the upper side of the device 

while it works to connect the split gamepad 

on the lower side of the device 

but both split gamepads could have clamps 

that clamps them to the device 

so that the right split gamepad 

clamps onto the lower side of the device 

while the left split gamepad 

clamps onto the upper side of the device 

both split gamepads would each use their own batteries 

to power themselves 

and connect to the device wirelessly
