Smart USB Power Switch

The TP-Link SMT196 is a compact Wi-Fi adapter that adds smart control to USB-powered devices. It connects to a 5-12V DC power source and lets you manage connected gadgets remotely via the eWelink app. The unit features both USB-A and USB-C output ports for versatile compatibility. Voice control is supported through Alexa and Google Home integration.

Home Automation Users

This switch suits anyone wanting to automate LED strips, desk fans, lamps or small USB pumps using a smartphone or voice commands. The timer function allows custom on/off schedules for daily routines. It is not for buyers who need a USB data hub or a network adapter for internet connectivity. The device handles power switching only and does not pass data signals.

5-12V DC Input Range

The adapter accepts a 5-12V DC supply to operate its wireless radio and relay. This voltage window determines which power sources can drive the unit safely. The FCC ID 2A4I5-EWB4CH-B1 confirms regulatory compliance for wireless operation. Verify your power source matches this range before purchase.
