In the video, a person is holding a small black device in their hands. The device has a red switch on the right side and a power outlet on the left side. The person flips the switch to the on position and then flips it back to the off position. The device appears to be a power inverter, which is used to convert DC power from a battery or other source to AC power for use with electronic devices. The person's hands are visible, but their face is not shown in the video. The background is a plain white wall.
