Tablet USB Host & Charging Adapter

The STS-2UE adapter provides wired Ethernet connectivity and simultaneous charging capability (SimulCharge) for select Samsung tablets. This adapter includes two USB-2.0 (A-Type) ports for connecting two additional peripherals. LAVA’s SimulCharge technology allows the tablet to operate as a USB Host while continuously charging the battery.

Standard USB OTG Adapters do not allow the tablet to be charged while operating with USB accessories. This intelligent adapter is designed for robust operation allowing rapid switching between SimulCharge and Charge-Only mode.

The LAVA product can be switched into Charge-Only mode to rapidly replenish the battery in the same manner as USB Charger with a Direct Charge Port (DCP) as defined by the USB Battery Charging specification v1.2.

The STS-2UE can be used on its own, or as part of a third-party enclosure solution, supporting a variety of kiosk-type
