The video shows a person holding a red and black device, which appears to be a portable battery charger. The person is demonstrating how to attach a black USB cable to the device. The device has several ports, including a USB port, a micro USB port, and a lightning port. The person is holding the device in their left hand and the USB cable in their right hand. They insert the USB end of the cable into the USB port on the device and then attach the other end of the cable to a device, presumably to charge it. The person is wearing a red shirt and is standing in front of a red background.
