Amazon is offering its Smart Plug for $13 during the current Prime Day event, marking a 48% discount from its usual $25 price tag. This represents a record low for the device. The Smart Plug, compatible with Alexa, allows voice control of appliances like lamps and coffee makers. It's easy to set up through the Alexa app and doesn't require a smart home hub. Its compact design allows for use in standard outlets without blocking the second plug.
