In parallel circuit arrangement you get the same voltage for all circuits as at mains. You know that all the electrical appliances are designed for a standard nominal voltage.

A series arrangement will have the obvious disadvantages that unless all the appliances are not turned on, the circuit will not complete and no gadget will operate. But more importantly there will be a voltage drop associated with each of the electrical appliance and your gadgets will get a low voltage than required and may get damaged. And even if it works, it will not give you the rated/designed output.
