Tablet USB Host & Charging Adapter

Designed for commercial/OEM applications, this intelligent adapter makes it possible to not only simultaneously operate your Samsung Galaxy Tab 4/S in host mode and to charge it at the same time, but also provide critical control of OTG modes. These features are useful when installing tablets in kiosks or other commercial applications.

This adapter is designed for robust operation, with more advanced Accessory Charging Adapter (ACA) mode switching, and even more stable tablet charging characteristics than the LAVA TL-002 adapter.

This adapter is not provided with a case.


OTG Device
Samsung Galaxy Tablet (see compatibility list of supported devices)

USB Charger/Power Supply with a Micro USB-B connector, such as the power supply provided with the Galaxy tablet. Any regulated 5 volt power supply capable of at least 2 amperes can be used.

The DC Barrel Jack can be used with a 5-volt regulated power supply. The jack is rated for 3.5 amperes. The jack has a 2 mm center positive pin. The DC Barrel Jack is an option, therefore is not populated on the standard product.

The power supply must never exceed 5.25 volts. Only one of the two power inputs are to be used.

Note: The custom 8″ cable connects the STS device to the tablet.
