Kmart have another Anko PS5 dual controller charging dock on sale like the $3 version. This one lies flat and there's a display which goes green when the controller is fully charged and red when it's charging. There are two detachable USB-C adapters that you can plug into the controllers and a USB-C cable comes included.
It's not available online, however you can view the manual here.
That's too low for the DualSense which needs 1500 mA minimum. Don't recommend using this at all.
