Standard USB OTG Adapters do not allow the tablet to be charged while operating with USB accessories. The USB Host Mode detects that a USB accessory has been plugged in and automatically switches to operate as a USB Host Controller. USB OTG allows devices to switch back and forth between the role of host and client. When operating as an OTG USB host, the tablet as a Host is expected to supply power to the attached USB accessories, which means power is drained from the tablet or phone battery.

Simulcharge mode informs the tablet or phone to operate as a USB host
controller, but not to provide power for USB accessories. With Simulcharge mode active, the tablet is expecting power to be provided to it for battery charging and running the tablet. This allows the tablet to be run simultaneously while interacting with one or more USB accessories. When the tablet operates in Simulcharge mode it restricts the amount of power drawn from the external power source.
