I use an additional portable 5000 mA USB source for power. And when choosing this camera, remember: 1 takes good pictures - a camera (it was made for this), 2 shoots video well - a video camera (it is made for this), 3 For every situation - the right gadget! An action camera is needed for shooting in fast motion and you don’t have to wait for miracles. For miracles, there are image and video processing software products and direct hands.
