[0002] In the work of photography and videography, in addition to the photography and videography unit, auxiliary equipment such as monitors, fill lights, microphones, electric focus devices, image transmission, etc. are also needed to complete the shooting. These devices are generally installed on the shooting kit, so each device needs to use a different power module, and the power supply voltage of different devices is different. At present, the power supply method is partly powered by the additional output port on the camera battery, and partly requires an additional power module to be installed on the kit to power the accessories, which increases the number of accessories around the photography and videography unit, which not only takes up space but also is cumbersome to operate.
