What's the difference between a smart plug and an ordinary socket?

Helium krypton smart plug will analyze it for you from several points.

Ordinary sockets can only be controlled manually, which means that they can only be controlled by touching them.

Smart plug, can be controlled by mobile phone? But also can be automatically controlled by the device itself.

Like what? For example, your mobile phone is charging? Is the kettle boiling hot water? People go shopping? What if it's an ordinary socket? Turn off the switch when the hot water is boiling? So we're in a hurry? And a smart plug? You're outside? When the water boils. Will the smart plug automatically turn off the power? Disconnect the hot water kettle? And the phone will charge? When the phone is full? The socket will also disconnect the power of the mobile phone? You forgot to boil water at home? Will people go out? At this time, you can only run back and turn off the ordinary socket? There is also a smart plug, which can take out the mobile phone and send a shutdown signal to the helium-krypton cloud platform through the mobile phone? And pass on the instructions? Turn off the electrical outlet at home.
