Fujifilm X-h1 power supply fix In: Cameras Posted May 9, 2018 6 hours ago, Vladimir said: output of an original dc power supply is 9V 2A. Are you sure that DC power supply is made by Fuji? 6 hours ago, Vladimir said: maybe there is converter inside original dummy battery. Or maybe the camera just runs hot and noisy when powered by 9V. The voltage of the X-h1's internal battery is definitely 7.2V. I would avoid running any camera at a voltage higher than that of its internal battery.
