Smart Plug for Home Automation

The Black & Decker S40TPB is a Wi-Fi enabled smart plug rated at 15 amps and 1800 watts on a 120 volt circuit. It installs by plugging directly into a standard indoor outlet and connects to the eWeLink app for remote switching. Voice control is supported through Alexa, Google Assistant and IFTTT routines. No separate hub is required for operation.

Indoor Use Only with Single Outlet

This device suits renters and homeowners who want to automate lamps, fans or small appliances from a phone or voice assistant. The single receptacle and indoor enclosure mean it cannot control hard-wired fixtures, outdoor circuits or multiple devices from one unit. Builders needing weather-proof boxes, DIN-rail mounting or multi-gang timer panels should look elsewhere.

15 Amp 1800 Watt Rating at 120 Volts

The plug handles resistive loads up to 1800 watts at 15 amps on a 120 volt supply. Exceeding this limit will trip the internal protection or damage the relay. Always verify the connected appliance draws less than 15 amps before use.

Questions about this item

Does the S40TPB generate noticeable heat or noise when running continuously at its 1800 W rating?

The switch is rated for 1800 W at 120 V with an operating range of -10 °C to 40 °C and has no moving parts, so it runs silently and stays within safe temperature limits under normal indoor use.

What must I already have at home for the S40TPB to function?

You need a standard 120 V indoor wall outlet, a 15 A circuit, and the eWeLink app on a smartphone or tablet; the device connects directly without a separate hub.

Will the S40TPB interfere with older appliances or legacy wiring on the same 15 A circuit?

It draws only the load of the plugged-in device up to 1800 W and uses a single-pole digital switch, so it behaves like a regular timer on existing 120 V circuits without affecting other equipment.
