Smart Plug for Appliance Control

The TP-LINK S31 is a 15A smart outlet designed for indoor use with lamps, heaters and other household appliances. It connects to a 2.4 GHz Wi-Fi network and is managed through the eWeLink app. Voice commands via Alexa or Google Home provide hands-free operation. The plug is ETL, FCC and RoHS certified for safety.

Fits a Standard Wall Outlet

The compact white unit plugs directly into a North American socket without blocking the adjacent receptacle. No hub or additional wiring is required; the device joins the existing Wi-Fi network during a brief app pairing process. Once connected, it frees the user from manual switching and enables remote on/off control from anywhere with internet access.

Monitors Energy for 100 Days

Real-time power, current and voltage readings appear in the app, and up to 100 days of consumption history are stored for review. Schedules and timers can automate daily routines, while smart scenes let one device trigger another. The 15 amp rating supports common resistive loads, but high-draw equipment exceeding this limit is not suitable.

Questions about this item

What is the maximum current the 15A outlet can handle before the ETL-certified safety limit trips?

The outlet is rated for 15 amps and carries ETL certification, so the internal protection will interrupt power if the connected load exceeds that 15-amp threshold.

How much heat does the plug generate when it runs continuously at full 15-amp load for a full day?

The unit weighs only 0.09 kilograms and uses a compact 72-inch form factor, so sustained maximum load will produce noticeable warmth but stays within ETL-certified thermal limits.

Which Wi-Fi band must my router broadcast for the S31 to connect during initial setup?

The plug requires a 2.4 GHz Wi-Fi network; it will not pair with a 5 GHz-only SSID, so ensure your router has the 2.4 GHz band enabled before starting the eWeLink pairing process.
