Overloading a single extention cord may lead to an electric fire and a terrible accident. Since you can’t tell how much electricity you are using at any given time, you don’t see the danger. The Smart Power Manager will let you know whether or not it’s safe to plug in another appliance. If the load is getting close to the danger limit, it will warn the user to unplug at least one household appliance before plugging another one in.
