Description

The present invention relates to, for example, a power supply device including a power strip to which a power cable of an electric product such as a personal computer or a tablet is connected.

In the office, unlike ordinary households, there are many opportunities to use electric appliances such as personal computers and tablets, but the places where power outlets are installed are limited in the office. If digital work can be performed in a place away from the installation location of the power outlet in the office, it is thought that the office environment will be comfortable and the choice of working place will be expanded. It is necessary to change or add a power outlet. At that time, if the power outlets are added in the office work, it takes a lot of time and money to peel off the walls and flooring to pass the wiring.

Conventionally, for example, there is a storage case for storing and transporting a projector (see, for example, Patent Document 1). The storage case has a case body in which a projector or the like is stored, and a battery for supplying power to the projector is stored inside the case body. Wheels are provided on both the left and right sides of the bottom of the case body, and the storage case can be transported by holding the grip portion on the upper part of the case body.
