Benefits of three-in-one extension cord
Compared to an extension cord with a single outlet, a heavy-duty extension cord with three outlets can connect three appliances at the same time. You dont have to worry about insufficient interfaces. For example, when you need to connect a lamp and an oven at the same time outdoors, but there is only one wall socket, then an extension cord with only one interface obviously cannot meet your requirements. Then you will need a multi-outlet extension cord to connect multiple appliance.
